81″ Long Rectangular Fabric Expansion Joint for an Offshore Oil Extraction and Natural Gas Project

February 21, 2012

A total of three rectangular fabric expansion joints and six round fabric expansion joints were custom designed for an offshore oil extraction and natural gas project. The rectangular joints are 56″ x 81″ I.D. x 25″ O.A.L. and the round joints are 105″ dia. x 24″ O.A.L. 309 stainless steel was used for the duct, 310 for the liners, 316 for the covers, 321 for the studs, 309 for the flanges. The fabric belt was a three layer belt with an inner layer of glass cloth, a layer of Kaowool and an outside layer of reinforced PTFE. The expansion joints were designed for 1 psig at a temperature of 1100°F. The rectangular joints were designed for 2″ axial compression, a 1″ extension, and a 1″ lateral offset. The round joints were designed for 4″ axial compression, a 1″ extension, and a 0.5″ lateral offset. All welds were 100% dye-penetrant examined prior to shipment.
