U.S. Bellows designed universal expansion joints for a wastewater treatment plant in Florida. This was done for a longtime client and market leader in wastewater management, energy services, water, and wastewater treatment. The units are 60″ tall and have a 26.75″ inside diameter. The bellows, cover, liner, and weld-ends are fabricated from 304 stainless steel. They are designed for an operating temperature of 1000°F at 11 psig, with 2″ axial compression and lateral deflection. The units were pneumatically tested at 12 psig prior to shipment. The on-site inspection was done by the client and the EPC firm at our manufacturing facility with our Engineers present to provide any additional clarity that was needed.
U.S. Bellows, EJMA member, is a leader in bellows design and manufacturing. With our manufacturing and engineering both in Houston, we have over 45 years of experience and have deployed over 250k expansion joints which does not include maintenance and repairs services conducted by our highly qualified field service team.
Custom expansion joint design and manufacturing is a complex process and we execute it effectively by focusing on the approval drawings from the customer side, training on customer support with all functional teams (production, engineering, shipping, and sales), and inter-team communication. We developed and deployed digital work instructions for all key production steps and added detailing and reviewing checklists of all of the expansion joint drawings before releasing them to fabrication. These improvements have reduced considerably the number of revisions and reworks. Some insight into jobs we have conducted successfully include:
- Refurbished 6 48″-64″ Refractory-lined Expansion Joints for a Large Houston Refinery during a 45-day turnaround
- Completed a large ducting project for a Major Chemical facility in Texas with on-time delivery
- In the last 6 months, 40% of our expansion joint jobs have shipped in 2 weeks
