October 31, 2016

132483a1

Type: Hinged Expansion Joint
Size: 66″ in diameter and 39-3/8″ OAL
Material: Incoloy 825 / 321 stainless steel
Design 73 psig at 986°F with 4.25 degrees of angular rotation
Testing: Dye Penetrant, X-Ray, PMI, Hydrotest

These single hinged expansion joints were custom designed by U.S. Bellows for a chemical plant in Saudi Arabia. The units are 66″ in diameter and 39-3/8″ OAL. The bellows are fabricated from Incoloy 825 with the weld ends, hinges, liner, and cover from 321 stainless steel. The expansion joints are designed for an operating pressure of 73 psig at 986°F with 4.25 degrees of angular rotation. All units were dye-penetrant tested, X-ray tested on all bellows and pipe longitudinal weld seams, PMI tested on all alloy components, and the alloy steel plate for the pipe was ultrasonic tested prior to shipment.
