U.S. Bellows, Inc. Fabricated and Designed 5 Expansion Joints for a Heat Exchanger Company in Japan

April 5, 2006

These single expansion joints were fabricated from ASTM-A-240 Type 321 stainless steel bellows and liners. The shell material is ASTM-A-516 Grade 70. They are 32 diameters with an overall length of 26″. Each joint weighs 280 lbs. They were designed for 150 PSIG at 650F with a travel capacity of 0.33″ axial compression and 0.08″ lateral deflection. These expansion joints absorb differential expansion between the shell side and the tube side of a heat exchanger.

They were hydrostatically tested to 208 PSIG to comply with the Japanese code, Ministry of Health, Labor and Welfares (MHLW), and the ASME Pressure Vessel Code Section VIII
