Excavation Equipment

These days there is no need for any construction job to go ahead without the proper excavation equipment. Many excavators or other kinds of machinery can be made to do several tasks with additional attachments. Backhoe buckets can easily be replaced with other backhoe attachments such as the backhoe debris fork that attaches to the bucket and doubles as a forklift.

Excavator attachments include such things as stump grinders or splitters to get rid of those stumps from your paddocks, brush cutters for clearing brush and stirrers for mixing solid aggregate or slurry. Buckets for excavators come in various sizes, making it easy to get just the right one for your excavator.

However, before buying attachments for your backhoe or excavator, make sure that it is attachment-ready. Most manufacturers claim their machinery will accept any kind of attachments made for them, but you may need to buy different couplers, hoses, control mounts and clamps, for such attachments may vary. No use getting out on the job and finding you need another trip to town to purchase the right clamps or control valves.

However, if you can purchase those attachments that do not require any additional device to ensure they work well, then you will save a great deal on the cost and the time spent in attaching them.

Having many additional attachments for your excavators or backhoes will ensure greater flexibility and enable you to do a great many more jobs. Thus much more contracting work will become available to you as a contractor.

Some attachments fit between the main vehicle and the additional tool, enabling it to work with greater flexibility, rather like a wrist provides to the arm. When such additions are quick to attach and fit they save a great deal of time and work for the operator, enabling him to remain on schedule with the job.

All About Brass Tubes

Sparkling materials like gold always attracts people. It also exudes elegance and style especially if seen as a decor in houses. But since gold is a very expensive material, people find other products that will be an alternate to the element. This is where brass comes in.

Brass is an alloy of zinc and copper. It resists corrosion and is better than other materials. However, it bends and dents easily so it needs proper care. There are different forms of brass that are known even in the old times but it was not recognized by metallurgists as a metallic alloy.

In homes, brass is widely used as a decor. It can be used in railings, curtain rods, hand and foot rails as well. Brass tubes are normally seen as round type. Aside from the round type, there is also square, rectangle, ornamental, and round roped, among others. Furthermore, the ornament tubing has several types like the twisted octagonal, hexagonal, and round embossed. So if you are thinking of incorporating brass tubes in your home, you have a wide range of styles to choose from.

Aside from brass tube as a home decor, it is also the material used in making musical instruments. Trumpets, baritones, and trombones along with other musical instruments are made from brass. Consequently, brass’ acoustic properties help in giving the instruments their distinctive, loud sounds.

Aside from being used as an instrument and home decor, brass tubing is also used in creating other products like faucets and other industrial equipment. So if you want brass tubing in your home or for any purpose, you can find brass tube suppliers over the internet that can provide you high quality products according to your sizing and specifications.

There are many reasons why brass tube is widely used. One of the reasons is its ability to resist corrosive solutions and its capability to destroy microorganisms that carry diseases. However, brass tubing needs to be cleaned and polished on a regular basis to maintain its beauty. This can be done by combining water and soap and using it to clean the brass. Then use brass polish to bring its shine back to its original state.

Save Money by Insulating Commonly Overlooked Systems

Although OSHA has strong requirements for overly hot pipes and fittings to be insulated, we often find that some systems are just overlooked. The common offenders are listed below – if you’re not insulating these systems, not only are you losing heat and money, but you may be setting yourself up for legal actions down the road.

Steam Traps

Steam traps are commonly overlooked when it comes to insulation. Definition: Steam traps are the mechanisms that allow the water that condenses from the steam (“condensate”) to pass from the steam system into a system that allows it to be reused without losing valuable steam and heat. The traps are typically missed because they are a smaller item that is often out of the way. Furthermore, steam traps need to be inspected periodically (at least semi-annually), and pipes that require inspection are often left uncovered, despite OSHA requirements. Steam traps have moving parts that wear out: another reason that the insulation needs to be removed, often resulting in no insulation at all.

Steam Trap Stations

Steam trap stations are also “no insulation” victims. The purpose of the trap stations is to strain out the big chunks of non-steam, such as metal, broken gaskets and other debris. Stations also isolate the actual steam trap from the rest of the pipe system, so that the steam trap can be maintained without taking the whole system down. Like steam traps, the stations are small and out of the way (since they are part of the same system as the actual traps). Furthermore, the Y-strainer (the part that catches the big chunks) has to be cleaned out. Once again, insulation may be avoided to reduce the expense of repeatedly ripping it off and reinstalling it.

Shell and Tube Heat Exchangers

Why don’t they have insulation on them? Definitions first: a heat exchanger is a device that transfers heat from one place to another. Cars have heat exchangers: the water that cools off the engine becomes hot, and that hot water then is used to heat the car on cold days and nights. Shell and tube heat exchangers (a specific kind of exchanger) are usually insulated to start with, but as soon as the insulation has to be torn off (e.g. for maintenance or a leak), the facility may conveniently forget to reinsulate. Reinsulation is not a priority because this type of exchanger is complicated to work with – it is not a smooth pipe, but rather, has numerous valves.

Plate and Frame Heat Exchangers

This is a different kind of heat exchanger, and the reason it’s usually is that it has a rectangular shape. Conventional insulation (fiberglass board) is difficult to wrap around plate and frame heat exchangers. Facilities that do not take advantage of reusable (and flexible) insulation often ignore these square exchangers.

Expansion Joints

Expansion Joints are in need of insulation, but so often ignored. Pipes aren’t always hot. They get hot and then cool down. Hot pipes expand, and they contract when they are no longer hot. Expansion joins safely absorb that expansion and contraction. However, regular insulation is not flexible enough to handle a joint that is all about flexibility – and so they are ignored.

Triple Duty Valves

Triple duty valves are often an orphan in the family of insulation. A triple duty valve has three jobs (shutoff, check and flow balancing), but the reason that it is overlooked are the little connection points on the vale. A flow meter is attached to those connections, and is used to check and adjust the flow. In other words, it is used so much that covering it with insulation is inconvenient (unless the insulation is easily removable and reusable).

Polyethylene Liner – Advantages Of Installing It

Currently many people are installing polyethylene liner in place of ordinary pipelines. This is because all of them are trying to get rid of the frequent leakage problems. Visible leaks are easy to repair and they do not cause any damage to your house. Whereas, invisible leakages can anytime bring down the entire setup.

Why should we use high density polyethylene liners?

Protection of Our House:
Currently, in every house, water channels are embedded under the floor and below the tiles so that your room or bathroom looks more sophisticated and spacious. House being the ultimate cozy corner of every individual as well as the most private and restricted area, we spend a lot of time and money in decorating in the best possible way. Everyone of us try our level best to improve the visual appearance of our home or house to the maximum extent. We furnish our home with the trendy furnitures and lightings and wall decors. But water can damage the entire show of the house and also soften the tight brick and mortar and make it very brittle.

As nowadays, water channels are concealed, hence it is very difficult to identify leakages under the floor tiles and behind the walls. Ceramic tiles are not waterproof but are water repellent (that means they block the passage of water). These tiles are held together with one another with layers of cement mortar. This gives a feeling that everything is dry and warm but in reality water seeps in through the tiny “weep-holes”, which is not visible to naked eyes. When it remains unnoticed for quite some time, then you will see the damp patches all over the walls and also on your wooden furnitures. Water can damage your paint, furniture, softens the brick and mortar etc. Thus it can ruin your sweet home.

Durable Pipeline Network:
HDPE polyethylene liners prevent frequent leakage. Hence it protects your house from damp problems. These types of pipes are highly weather resistant and thus prevents pipeline corrosion. These type of pipes can easily withstand the extreme temperatures. No matter how clod, dry, hot and moist the temperature is, these special pipes are very durable in all types of climatic condition. The materials used in manufacturing these pipes are highly inert and does not tend to change in extreme atmospheric conditions.

Easy To Install Facility:
It is very easy to install HDPE polyethylene liners. The trench less technology applied in the process of installation makes it a zero leak substance, thus ensuring a long time security. Usually, the liner pipes are manufactured a bit bigger in diameter than the host pipes. The fusion process is a crucial part, which is responsible for judging the quality of the substance. The fusion process is carried out in a highly protected enclosure, which acts as a thermal controlling unit. The entire fusion procedure depends on appropriate cooling and heating period.

Therefore, you can install polyethylene liners anytime and anywhere, in order to avoid leakage problems and then searching for good plumbers.

Optimized Manufacturing Includes Packaging Automation Robotics

Packaging automation robotics must be part of the overall optimization of product manufacturing. Even small manufacturers can realize the return-on-investment for capital outlay for packaging automation robotics in a reasonable period of time. It is not unrealistic for such a capital expense to get paid back in as little as 18 months. This, by itself, should warrant a very serious look by all manufacturers who have to package their products before shipping to customers. Technology has moved packaging automation robotics forward in that the equipment that you can purchase now to perform this task can be readily integrated with your existing production line.

The first level or primary packaging usually occurs right after a product has been manufactured. This process amounts to putting the product in its first level of packaging. This can be a plastic closed end wrapping like for a candy bar or a bar of soap. A second level or secondary wrapping most always will occur. This happens when the wrapped product is bundled in some way with several other units of the same product or the wrapped product is put into a box. This secondary packaging is sometimes added to products because they need security or tamper-resistant packaging. Both these levels of packaging can be administered by packaging automation robotics. Secondary packaging can be warranted by the distribution method of the products. Sometimes products need more protection due to the handling that they may get during distribution.

Delta robotics to assist in the first level packaging of products in the production stream makes it easy to integrate packaging into the line using current equipment. There may be slight adjustments that have to be made in current production equipment to optimize the packaging capability into the line. In a lot of cases in food product packaging Delta robotics are the optimum selection for packaging delicate food items into their initial wrapping. The delicate touch of Delta robotics accomplish this task very readily. Usually products are loaded into packaging on the horizontal plane for this first level of wrapping. Adding vision capability to the robotics will allow the products that are to be packaged to enter the packaging work cell in random orientation. This packaging solution should not interrupt, but should help to optimize, the production flow.

Delta robotics can also be implemented as the second level of packaging automation robotics. Top loading is the method that is used in some cases to put products into a second package. This is called top loading because the previously wrapped product is inserted into a carton or other substantial wrapper by being inserted from the top of the wrapper. Sometimes these products that have both first and second level packaging in place are collected into groups of products and inserted into a third level of stretch wrap, tray or carton.

There are different types of patterns of presentation that products with which products can be moved into the packaging area. The type of presentation will depend on how the packaging equipment is best included into the overall flow of the production line. The collation pattern brings the products to the packaging operation in a single stream. Products are grouped or collated into a given count so that this group of products can then be wrapped. This can be eight first or second level packaging. Delta robotics are often used for the “pick and place” of these products for packaging.

Perpendicular presentation occurs when the products are brought to the packaging area at right angle to the packaging process. This method can be effectively used for raw food products that are to be packaged by the first level of packaging. Delta robotics perform this operation very well. The robot can be joined with vision capability to get optimum results. The inline presentation can be used to get products to the packaging area either in multiple or single streams. Often the flow of products to be packaged opposes the flow of packages into which they are placed. This allows the robotics to have a full stream of products to pick from in order to effective packaging.

To get optimum results from packaging automation robotics more than one robotic can be used to increase the speed to a higher production rate. A single controller can be programmed to control more that one robotic to do both first and second level packaging. Programming can be adjusted to fit exactly into the speed required by both upstream and downstream equipment. The speed of the production line is going to be influenced by the delicacy of the products being wrapped. Softer, more pliable products usually require a slower speed when being produced and packaged. The capability of the packaging robotic should, however, be able to handle any product consistency at any speed. It is very easy to vary the programming that controls robotics to get the optimum packaging result that is required.

Gas Adsorption Measurement

Gas adsorption measurement is an important technique to determine the specific surface area of powders, solids and granules. This article provides an introduction to gas adsorption (including physiosorption and chemisorptions) plus the theory and practice of measuring it.

What is gas adsorption?

When a gas and solid come into contact they can interact in many different ways, so first off let’s outline some definitions to help when describing the various processes. The adsorbent is the solid whose surface the adsorbate (gas or vapour) accumulates in some way.

As well as absorbing the gas (see below) the solid may take up the adsorbate in a process called adsorption due to the attraction of atoms or molecules in the gas to the solid surface. This results in layers (or films) on the adsorbent’s surface with the kinetic energy (of thermal agitation) being transferred into the solid surface.

The phenomenon has been studied since the 18th century when it was first noticed as the uptake of gases by charcoal which is still an important application today with activated carbon having a very large surface area and high degree of microporosity. Gas adsorption is also an important factor for the function of catalysts which need to bind the reactants quickly and effectively and also release the products of the reaction.

Gas adsorption can be sub-divided into physisorption (physical adsorption) and chemisorption (chemical adsorption) depending on how the molecules and atoms attach themselves to the adsorbent.

Physisorption is where the attraction is due to the long range but weak van der Waals force between molecules in the adsorbate and the surface. The molecules do not react with the adsorbent and the chemical identity of the adsorbate remains unchanged.

On the contrary, chemisorption is driven by a chemical reaction occurring at the exposed surface where a chemical bond is formed between the adsorbate and adsorbent. This strong interaction creates a new chemical species (and electronic bonds) at the surface and can be a greater bond than between the molecules in the gas themselves resulting in dissociative adsorption. Chemisorption is typically far more dependent on the chemical identity of the adsorbate and adsorbent than for physisorption.

Difference between adsorption and absorption

Gas adsorption refers to molecules in a gas interacting with a solid at its surface. Where the molecules actually enter into the inside of the solid this is termed absorption (or dissolution).

The term “sorption” refers to the action of both absorption and/or adsorption.

Gas Adsorption Measurement

Gas adsorption is usually measured to determine the specific surface area of a solid by measuring how much gas is adsorbed over the entire exposed surface of a material plus the filling of pores. The specific surface area (e.g. of powders, solids and granules) is defined as the total surface area per unit of mass and is expressed in meter square per gram (m2/g).

Isotherms are used to describe adsorption by plotting a graph of the number of molecules adsorbed per molecular mass of adsorbate as a function of its pressure at constant temperature.

The most common technique used to determine the specific surface area is BET surface area analysis which is based on a mathematical model for the process of gas sorption and takes into account multilayer adsorption.

Key points to consider when selecting scientific equipment for gas adsorption measurement:

  • surface area measurement range – Krypton typically used as adsorbate for surface areas down to 0.001 m2/g
  • physisorption and chemisorption support
  • desorption isotherms capability
  • speed & accuracy – sampling points v analysis time
  • unattended operation
  • cost and maintenance
  • size and footprint

Early attempts at drilling had to rely on the power supplied by man or beast. Just imagine turning those rods by hand! It was only after the internal combustion engine was invented that drilling could be done with any serious results. Even then, in the early days of oil exploration drilling rigs were semi-permanent; they were left onsite after the hole had been drilled and oil found.

These days, the use of custom made drilling rigs – and smaller rigs – means that they can be moved to another site while a different rig that is used to actually extract the end solution – whether that be oil, gas or water – takes its place. And while it does take time to dismantle the original, larger rig, it is still cheaper to do that than to leave it in place and be unable to use it to drill another hole elsewhere.

But because smaller rigs are often suitable for the job, they can be brought in mounted on trucks or tracked carriers to do the job, and after it is completed, they can be easily removed without any – or only a little – dismantling being done. The work is also expedited by using a rig that is capable of doing two types of drilling.

Thus, air core drilling through unconsolidated ground can be first carried out and when solid rock is reached, the same rig can be changed to do diamond core drilling with much less time and cost than bringing in a second rig.

Drilling can be classified by the use of several different terms or attributes; by the pipes used; the type of power used; by the height of the rig; by the method of rotation or by the position of the derrick.

  • Pipes – cable, conventional or coil tubing.
  • Power – mechanical, electric, steam, pneumatic or hydraulic.
  • Height – single, double or triple.
  • Method of rotation – top drive, rotary table, sonic, hammer or no rotation (direct push).
  • Derrick position – convention where the rig is vertical or slant where the derrick must be at an angle due to the terrain.

Plasma Cutters use for various purposes

Plasma cutter is one of the main devices used in many metal fabrication industries. It is a way to make fine cut in metal and they use high heat to attain high accuracy. The tool was first used during the 2nd world war and since than it has undergone through several improvements and upgraded many times to remain a very useful instrument. Plasma cutters use an inert gas and electrical energy to make a powerful torch so that it can slice metals.

Let us have a look on the various uses of this special device.
Movable or Available on site
As plasma cutters are handy, they can be used by several service providers to slice metal when they are working out on the field. It is easy for the mechanical contractor to repair the item on the client’s site itself, instead of bringing the big portion of metal back to the store for repairing it. Many times you just need a normal trim in order to join two metal pieces together and if you have a plasma cutter right there then it makes your task done within few minutes. On the other hand when you don’t have this particular tool, you have to wait for the manufacture store to make the essential modifications.

Used in art
In order to create exclusive works with the help of metal, many artists utilize small size plasma cutters. Tip of this machine can create very fine slice and allow the artist to make multiple models in metal. Various patterns can be formed with the help of plasma cutter, which can be used as an outline for other template of art.
Demolition or annihilation

As plasma cutters have the ability to slice the large and heavy sheets of metals, they are also getting their way into the demolition industry. The capacity of their beam permits the demolition team to take out pipes and structures more quickly than the hand cutter or when the metal had to be cut manually. With the help of this device metal sheets can be carved into small-small pieces so that it will be much easier to manage them and to load inside the trucks for elimination from the site. Hence, they make disposal of the material much more convenient.

Cutting the pipeline
Accuracy is the main result when working with plasma cutter and it is useful for plumbing service provider. If a standard torch is being used to carve pipes, the ends can become flattened and it makes the task much complicated when it comes to fit the ends of both pipe’s parts together. Tip of the plasma cutter leaves a much more silky edge than a blade. This cut down the time that should be spent to grind the edges of the pipes.
