U.S. Bellows, Inc. specially designed and fabricated two 770 lb. pressure balanced expansion joints for a company in Ohio. These expansion joints, designed for 450 PSIG and 1350 °F, will be used for wind tunnel testing of airplanes and engines. With an overall length of 70, these expansion joints consist of four 8 diameter bellows with 3 plies of Inco 625 Gr1 material, an 8 diameter Inco 800 HT elbow, four 74 A193 B8 tie rods, and four 2 thick A240 tp304H rings. To ensure quality, 100% x-ray and 100% dye-penetran tests were performed on the bellows. A pneumatic test at 550 PSIG was conducted on the entire assembly prior to shipping
