U.S. Bellows/PT&P Manufactures Three 36" Expansion Joints for an E&C Company in Singapore --11/08/99
In October 1999, U.S. Bellow, Inc. fabricated three expansion joints for an E&C company in Singapore. The expansion joints manufactured included one 36" single hinged expansion joint, one 36" double hinged expansion joint and one 36" double gimbal expansion joint. These expansion joints will be used at a compressor in Singapore. Due to the critical applications of these expansion joints, they were tested per ASME Sect. VIII Div. 1 Appendix 26. The bellows together with the hinge assembly were hydro-tested. Additionally, a dry nitrogen test between the two plies was conducted to ensure that each of the two plies would withstand the design pressure. Gimbal expansion joints allow for restrained angular movement of attached piping in two planes. Expansion joints, in general, allow for axial, lateral, angular and torsional movement in piping systems.

U.S. Bellows, Inc., manufactures a full line of expansion joint products. This product line includes: fabric expansion joints, thick-wall metallic expansion joints, thin-wall metallic expansion joints, slip-type expansion joints and rubber expansion joints. U.S. Bellows/PT&P has extensive experience designing and manufacturing products of this type per EJMA and ASME codes. Piping Technology & Products, Inc. and its wholly owned subsidiaries U.S. Bellows, Inc. and Sweco Fab, Inc. are manufacturer’s of a variety of high-quality, engineered products. They are located in Houston, Texas, USA on a 22-acre property with more than 450,000 square feet of covered shop space.
