Read MoreThis single tied expansion joint was designed to withstand 400 PSIG and 200°F. The bellow was manufactured using B443 material (Inconel® 625) with a 300 lb. carbon steel flange. It measures 8” x 16” with 3/16” lateral movement. Pressure testing and 100% dye-penetrant tests were performed to ensure quality.
The rectangular fabric expansion joints consisted of two carbon and stainless steel frames separated by a high-temperature Silica fabric. The frames measured 13” × 37” × 6”, 14½” × 20½” × 6” and 17¼” × 17¼” × 4” and weighed 90, 115, and 170 lb. Each expansion joint was designed for a 15” Water Column (W.C.) with a temperature of 750°F and allowed for movement ranging from ±½” to ±1” in both the axial and lateral directions.
U.S. Bellows, Inc. custom designed and manufactured a 60” diameter and 120” long universal expansion joint for a chemical plant in Louisiana.This metallic expansion joint was fabricated from 304 stainless steel bellows and carbon steel. It was designed for 10PSIG and 550°F. To ensure quality a 100% dye-penetrant, radiography, and soap leak test was performed prior to shipment.
This 3,400 lb. expansion joint is capable of 2.3″ lateral movement and 1.5″ axial movement and was designed for 65 PSIG and 1076ºF. It was made with SB-409 alloy 800 bellows and 316H piping and gimbal components. The dimension of this expansion joint is 24″ x 168″ x 71″. This gimbal expansion joint contains two sets of hinge pins or pivots with the axis of each set perpendicular to each other. To ensure the quality of the product, the joints were 100% X-rayed and hydro-tested at 120 PSIG prior to delivery.
US Bellows custom-designed and manufactured three 3″ diameter and 36″ long universal expansion joints for a power plant project in South Carolina. These expansion joints, fabricated from 2-ply A240-304H stainless steel bellows, are designed to withstand 170 PSIG and 1200°F per EJMA specifications.
