Fabric Expansion Joint Custom Designed for an Exhaust Application in a Gas Turbine Facility

This 153″ x 55″ x 21″ fabric expansion joint was custom designed for an exhaust application in a gas turbine facility overseas. It is fabricated from carbon steel with a painted frame and liner. The fabric belt is reinforced neoprene, and it’s designed for +/- 100″ water column with a temperature of -20°F to 600°F. A dye penetrant examination and paint thickness test was conducted on the assembly before being shipped.

44" Expansion Joints for a Petrochemical Plant

U.S. Bellows, Inc., a division of Piping Technology & Products, Inc., designed and fabricated 44″ fabric expansion joints for a petrochemical plant in Malaysia. The expansion joints measure 44″ ID x 40″ face to face and are fabricated from stainless steel pipe and flanges and a three layer fabric belt protected by an insulation pillow. The design conditions were 3 PSIG at 845°F. The expansion joints are designed for a lateral movement of 1/2″ and an angular rotation of 1.5°. Stainless steel covers were included to protect the fabric expansion element from possible outside damage.

These 59” x 39.5” fabric expansion joints were fabricated using a 1/8” thick neoprene sheet. The joints were then bonded to the carbon steel angles and plates, and secured using stainless steel band clamps, with T-bolt latches. The carbon steel angles and plates were primed and finished at Piping Technology & Products’ paint production facility. The expansion joints were designed to facilitate any vibration and movement during the generator units’ normal operation.
