U.S. Bellows, Inc. designed these single expansion joints
for a pipeline application in Louisiana. Each expansion joint measures 13.5″ in diameter with a 6″ overall length (OAL). The bellows and internal liner were fabricated from 304L stainless steel to provide enhanced corrosion resistance and durability, while the flanges were constructed from carbon steel for structural strength and cost efficiency.
These expansion joints were engineered to operate at a design temperature of 300°F and a pressure rating of 85 psig. The units were designed to accommodate 1″ of axial compression and 0.10″ of lateral deflection, ensuring the system can safely absorb thermal growth and minor misalignment within the pipeline.
Manufactured to meet design standards such as EJMA, ASME Section VIII, or B31.3 to reinforce engineering credibility, these expansion joints help absorb thermal expansion, reduce stress on piping systems, and extend overall system service life.
To ensure quality and reliability, all expansion joints were hydrostatically tested prior to shipment in accordance with applicable industry standards. This testing verified pressure integrity and overall performance before installation in the field. U.S. Bellows, Inc. specializes in the custom design and manufacture of expansion joints for demanding industrial applications worldwide.
