Is There a Right Way to Choose Welded Bellows?

Welded

At first glance, you may feel that welded bellows are much exactly the same, an easy task to spot and also there is no actual reason to be worried about details. There’s a perfect way to go about determining the ideal type of bellows for the project, and also following these simple tips could make the task a joy. Key factors include airtightness, durability, thermostability and KP-LOK corrosion resistance.

Consider the Plan

Bellows are widely used across many different actuation, fluid handling and sensing applications. There exists a widely used acronym, “STEP” which pertains to the four main types where welded bellows are used: sealing, temperature, pressure and evacuation. Bellows also perform differently under various kinds of load, therefore it is very important to look closely at the plan and materials when making your selection.

A special mixture of piston-like and spring-like action, bellows may convert pressure changes into applied force and redirect implemented force reactively. Welded bellows will exhibit a specific balance based upon the materials and construction method used in their manufacturing. Each kind has its suitable purpose, and also there are factors to consider that will put you to the perfect path to deciding on the ideal component for the project.

Welded Bellows Used

During their use, welded bellows make a flexible connection and secure, ideal for expansion joints and electrical interrupters. Additionally reactive to changes in altitude, bellows can adjust gas to atmosphere mixes. In pressurized uses, bellows respond in a linear way, which makes them useful in pressure springs and switches.

Temperature Extremes

Welded bellows made from stainless steel contain the capability to work well in extremely high and extremely low temperature environments, an average of -260° to 1200°. This level of versatility is ideal for software within power transmission systems, industrial controllers and electric interrupters.

Corrosive Resistance

Welded bellows might be made from an assortment of metals including stainless steel, Inconel, Haynes and Hastelloy, among others. Stainless steel offers high tensile strength – at the minimum of 90 ksi – and – high corrosion resistance, making bellows made within this material used in many media and environments.

Durability

Circular or rectangular welded bellows, when fabricated to the greatest specifications and fit bellow seal to the proper purpose offer extensive durability in the long run. Over 1,000,000 bicycles is a common standard for bellows of high quality. As a business that is dedicated to high-performance in production of fluid control systems and components is always achieving top notch standards in bellows and fluid system components development, and welcomes collaboration with organizations sharing those values.
