Hydro-Formed, Electro-Deposited, Mechanically-Formed, Edge-Welded Bellows
Flex-Weld, Inc. bellows are formed from TIG welded tubing fabricated, assembled, and
tested to exact specifications. A variety of forming methods can be utilized to achieve optimum
performance. Bellows can be selected or designed for any application or market. Single or multi-ply fabrication capabilities allow for a wide range of pressure, cycle life, or
spring rate requirements.
Flex-Weld, Inc.’s exceptional manufacturing methods result in a bellows configuration that
exceed each industry’s highest standards. Uniform wall thickness, symmetrical convolutions
and reliable spring rates are assured. All incoming material is metallurgically
checked to internal requirements. Our proprietary forming processes preserve and increase
the inherent strength and ductility of the bellows material to enhance cycle life and
fatigue resistance.
The most important feature of Flex-Weld bellows is the multi-ply geometry produced by
telescoping thin wall precision tubing. Utilizing the same dimensions, Flex-Weld bellows
can accept significantly more movements than our competitors. The stresses induced on
the individual layers of Flex-Weld bellows are a fraction of the stresses induced in single
wall bellows of equal thickness. This results in Flex-Weld bellows having a much higher
cycle life and lower spring rates than our competition.
