things-you-must-know-before-purchasing-precision-pipe-fitting-tubes

Precision pipe fittings, tubes, and adapters come in the vast range of products such as Hex Nipples, hex reducing nipple, adapter gasket, hex coupling, and much more. These are important partsof the industrial components, especially in the gas, power, fertilizer, and other industries.

It’s important for you to know the standard required before making the selection. These products should be made of very high quality raw materials to ensure the international quality.

Design features

These are the following design specifications to consider:

  • Fittings are properly packaged with exposed threads protected to ensure they are not damaged during delivery.
  • Working pressures calculated in accordance with Power Piping Code, Process Piping Code & Pressure Vessel Code.
  • Full form threads are machined to ensure leak-free & reliable systems.
  • Large choice of connections and configurations should be available.

How to select the right parameters

You need to ask right questions:

    • Can it bear the pressure?
    • Can it withstand the high temperature?
    • Are the joints and seals reliable?
    • Are the manufacturers reliable?

Choosing the right pipe fittings and adapters should be done with a lot of caution. Industrial applications are sensitive and compromise with the quality may result to untoward accident. Only those products should be selected that follow the Pressure Equipment Directive ofinternational standards

These are international standards for the design and fabrication of pressure equipment for piping, safety valves and other components and assemblies subject to pressure loading. Good companies such as Seal Excel follow such international standards.

Apart from that quality companies follows other international standards which ensure the safety of the equipment working in the potentially explosive material.

Certification ensures that the equipment or protective system is fit for its intended purpose and that adequate information is supplied with it to ensure that it can be used safely. There are four ATEX classifications to ensure that a specific piece of equipment or protective system is appropriate and can be safely used in a particular application.

Seal Excel instrumentation precision pipe and Tube fittings are completely heat code traceable. The company has a high standard of manufacturing process which completely follows the chemical and physical makeup. Our Instrumentation Pipe Fittings are manufactured under the international standard specifications and we strive hard to thoroughly clean the contamination during the process.

Summing up

Pipe Fitting Tubes are an important part of the industrial application and you need to be very careful while making the choice. Apart from the quality of the product, you also need to consider the brand and pricing before making the final decision.

Tips for Choosing the Correct Pneumatic Fittings

tips-for-choosing-the-correct-pneumatic-fittings

 

 

Typically, you will find a range of varying pneumatic fittings easily in the market. However, the problem is that choosing an appropriate one is not simple. To take the right decision, you must be aware of the tubing to be utilized, the functional pressure of air, type of thread required for the receiving fitting, and lastly, the extent of vibration tolerable by the fitting.

 

Commonly Used Fittings

Outlined below are some of the common kinds of pneumatic fittings to help you choose the right one:

 

Quick Connect Couplings

Quick Connect Couplings are indispensable when it comes to connections that direct the flow of gas, water or air. Alternatively known as quick disconnect or quick release couplings, they offer a swift connection for transferring fluids. Usually operated manually, they serve as a great substitute for threaded and flanged connections.

 

Check Valves

In the simplest sense, check valves permit the flow in a single direction; hence, preventing reverse flow. Being a self-automated valve, they consistently work even if the manufacturing facility falls short of air, electricity or manual assistance. Not just manufacturing plants, check valves are found everywhere – even homes. In case you have a sump pump, it must have a check valve fitted over the discharge line. Check valves are utilized in every industry that makes use of pumps.

 

Hi-Duty Flareless Fittings

These fittings fall into the sub-category of compression fittings. However, they are particularly made applications that involve high pressure; usually more than 1000 PSI.

 

Push-Connect Fittings

Push-Connect Fittings use a similar mechanism as compression fittings. However, instead of using a metal-ferrule, these fittings utilize an O-ring (made using vulcanized rubber) that possesses the ability to get its actual shape let loose.

Consequently, this feature permits the fitting to get easily undone—just the way it was manufactured. Push-connect fittings have applications that involve lesser pressure. These fittings are extremely simple to connect, disconnect and then reconnect, ideal for applications that involve frequent alterations. Moreover, they can be utilized with brass, steel, copper, nylon, etc.

In addition to the above stated pneumatic fittings, there are a range of varying options, depending on the application. The more different the job requirements are, the more atypical the fittings will be.

Generally, compression fittings, push-connect fittings, specialty compression fittings can be easily bought and utilized for a broad array of applications. Find a comprehensive range of pneumatic fittings at SEALEXCEL.

Recognized as one of the finest pneumatic fittings manufacturers and suppliers, we additionally manufacture stainless steel push-in fittings, push-on fittings, monoflange valves, and more.

Stainless steel tube fitting manufacturer improves productivity with new all-electric tube benders

vr-fittings

Wellington, New Zealand, March 23, 2016 — Two new all-electric tube bending machines are helping Ultibend Industries to boost the manufacturing productivity of stainless steel tube fittings for food and beverage processing systems. Customised to suit Ultibend’s proprietary manufacturing process, the machines from Unison automate the bending of tube fitting shapes such as elbows and U-bends, in sizes from 1/2 to 4 inches diameter. Initial manufacturing operations have demonstrated that the new machinery boosts manufacturing speed compared with the previous hydraulic bending process.

Ultibend started in 1992 as a subcontract tube bender, supplying architectural pipework. The company also found a market for tubular parts for the strong local food processing industry, and evolved from sub-contract work into offering a broad range of stainless steel tube fitting parts for applications including food, winery, brewery, dairy and sanitary processing.

As part of the company’s development, Ultibend designed and manufactured its own tube bending machines. There are now four of these machines and they have served Ultibend well, but they are hydraulically powered – and critically for the future development of the company – only offer a very basic level of machine and operator control. As the company has expanded, it became interested in upgrading the bending process with more flexible all-electric machines – using software-controlled servomotor controlled bending. Developing its own solution to this upgrade would involve familiarity with servomotor based motion control as well as much more sophisticated machine control and interfacing software – and it was viewed as too big a step for the Ultibend engineering team. So, it decided to look to the commercial market for an upgrade.

Ultibend settled on Unison as the supplier, largely because of the fact that it had started life as a machine controls and software supplier and that a large proportion of its output was customised.

“We didn’t want a standard machine, so discovering Unison was great. Their willingness to customise – and the fact that they are genuine machine control experts – gave us confidence that we would get the far-reaching solution that we were searching for,” says Ultibend’s co-founder and director, Linc Turley. “The investment means that our business now has the manufacturing platform to support substantial growth, including our current expansion into the USA and other new export markets.”

One of Ultibend’s unique advantages is the very high functional quality of its tube fittings. Bends are highly uniform, with the kind of ovality tolerances that would normally only be found in an aerospace workshop. This quality level is achieved by Ultibend’s proprietary manufacturing process, which means that bent parts are exceptionally uniform as they come off the machine. Ultibend also developed its own clamping system, which allows short elbow and U-shape parts to be gripped and bent at the expense of trimming only a miniscule amount of scrap material. Both of these techniques have been incorporated in Unison’s new customised machine design.

“Unison’s customisation capability means that we’ve been able to emulate unique features Ultibend uses in its process, and then exploit the all-electric machine architecture to enhance productivity,” says Jim Saynor, Unison’s Senior Commercial Manager. “The result is that the two new machines have increased output- while also providing much richer programming, networking and operator control facilities to open up further opportunities for progress.”

The main reason the Unison machines speed the bending is the inherently greater control of motion that’s possible inside Unison’s software-controlled, all-electric machine architecture. The software gearbox is able to control and coordinate several axes simultaneously for instance, avoiding the delays of a more mechanical machine such as the latency in response of a slave axis.
