Edge-Welded Bellows

Edge-Welded Bellows, also known as welded plate bellows, and welded diaphragm bellows, are essential engineered components in ultra-high vacuum and high pressure sealing applications. Their primary function is to compensate for system vacuum and pressure differentials during normal and upset operations. Secondary functions include mechanical sealing, vibration, isolation, compensation for relative movement between pipe sections, and reduction in forces and induced moments at various connections. In the bellows industry, edge welded bellows stand out in their ability to control large amounts of motion precisely and repeatedly.

Bellows Features

GST manufactures edge welded bellows from I.D.4.0mm through O.D.550mm, with many sizes in between. If we do not have the exact bellows size you need, we can manufacture a stamping die, in house, to meet your needs. The length of your final assembly is only limited by your application, as we have welded assemblies With our machine shop on site, we are able to manufacture everything from the simple tube to the most complex flange assembly, in a timely manner with the highest quality standards. We also specialize in quick turn around for bellows rebuild/repair. By re-using the end flanges from damaged bellows you can save yourself time and money, and limit downtime. Our Quality Control, which consists in part of inspection, leak testing and scheduled welder certification, through weld bead analysis, allows us to ensure the highest quality for our product.
