The bellows are fabricated from 304 stainless steel, and the pipe and flanges are carbon steel. The units range from 1″ to 8″ in diameter and are designed for a spring rate of 20 lb./in. The expansion joints are designed for 140°F at 25 psig and are capable of 1″ axial compression. Each unit was hydro-tested prior to shipment.

U.S. Bellows custom designed universal expansion joints for an oil refinery in the Philippines. The bellows and liner are fabricated from 304 stainless steel and the cover, tie rods, flanges and pipe spool are carbon steel. The sizes are 18″ dia. x 60.5″ long, 28″ dia. x 80.75″ and 36″ dia. x 40″ long. The units are designed with movement indicators and for 50 psig at 655°F. They are capable of 0.675″ compression, 0.375″ lateral and 1″ angular. The bellows and pipes were 100% x-rayed, PMI examined and hydro-tested

U.S. Bellows designed and manufactured this universal expansion joint in accordance with ASME section VIII for an oil and gas refinery in Europe. A U2A- form was furnished as part of the units’ documentation. The expansion joint has a 24″ diameter and 103″ overall length. The bellows, liners and covers are fabricated from 316 stainless steel, and the flanges, tie-rods and pipe are carbon steel. The unit is designed for an operating temperature of 181°F at 101 psig and 1″ axial movement with a 3″ lateral offset. The bellows and pipe longitudinal weld seams were x-rayed, dye-penetrant and hydro- tested prior to shipment

These universal metallic expansion joints were custom designed for a pipe line in a bioengergy plant. They range from 20″ to 30″ in diameter, and are designed for 2″ lateral movement with a 1,362 lb/in. spring rate. The expansion joints are fabricated entirely from 304 stainless steel and designed for 250°F and 30 psig. Each unit was 100% dye penetrant examined and air tested prior to shipment.

This pressure balanced tee expansion joint was custom designed for a boiler feed pump turbine exhaust in a power plant. It is 96″ Dia. x 288″ OAL and fabricated from carbon steel with 304 stainless steel bellows, turning vanes and liners. It is designed for 2″ axial movement at 315°F and 15 psig.
