As the sole United Kingdom distributor for Servometer©, Abssac can supply quality-crafted edge welded bellows.

In 2007, Servometer acquired BellowsTech, LLC.  BellowsTech is a premier manufacturer of edge welded bellows and assemblies, encompassing a wide array of alloys and dimensional configurations. BellowsTech and Servometer have a synergistic relationship to offer customers solutions and Abssac is proud to be part of that team. The technologies complement each other in size, compatibility, pressure and temperature limitations without sacrificing performance. The cross-over of engineering talent adds value and experience to ensure customers employ the right technology for their applications.

If you have an application where the control of volume in a liquid or gas is important, the edge welded bellows product may be able to help. Providing the most flex in the smallest amount of space, we are dedicated to developing and perfecting edge welded bellows design, fabrication and manufacturing technologies with full application design assistance.

Using state-of-the-art manufacturing capabilities allows our customers to  benefit  from exact requirements.  We excel at optimising the design and attachments so that we have consistently achieved outstanding performance and reliability reviews.  For applications that require high quality micro fusion joining, edge welded bellows are more cost effective and functional than either electron beam or laser welding.

Working within the size range of 12.7mm to 147mm (OD) and working in materials such as AM350, Stainless steel, Titanium, Hasteloy, and Inconel, we will design and manufacture bellows in 0.05mm  to 2 ply 0.18mm thickness. In fact we can weld any weldable alloy that is commercially available.

Your understanding of edge welded bellows does not have to end here. Did you know that edge welded bellows can be used as a liquid or gas accumulator, expansion joint, or actuator?

Hydraulically formed, or hydroformed, bellows can typically travel about twenty percent of their free length. Edge welded metal bellows have the ability to travel ninety percent; thus, edge welded bellows can accomplish the same movement in smaller sizes and lighter weight assemblies. Bellows accumulators can have pressure internal or external to the bellows assembly. This design factor should be defined early in the design phase since the assembly will ideally receive internal pressure. Understanding the differential pressure between the inside and outside of the assembly also helps engineers to determine the proper size and length of the bellows assembly.
