Steam Bellows Expansion Joints

Our Steam Bellows Expansion Joint is built for boiler plants, heat networks, and steam systems in chemical plants. We have been making pipe parts for over 20 years. This steam bellows expansion joint takes in axial, lateral, and angular moves. It stops leaks and stops parts from breaking. We use 321 or 310S heat-resistant stainless steel for the bellows. The flanges and pipes use heat-resistant alloy. It handles high temperatures and water hammer well.

This thing works from -50℃ to 800℃. It handles pressures from PN10 to PN63. Each steam bellows expansion joint gets a water test at 1.5 times the design pressure. We also do an air tightness test at 1.1 times. Its fatigue life goes over 10,000 cycles. We use heat-resistant graphite and metal for the seals. It gives you zero leaks and a long life. Our factory is 10,000 square meters with 50 workers. We have our own test machines. We give a 24-month warranty.

Every steam pipe has different temperature, pressure, and start-stop frequency. So you can change this steam bellows expansion joint to fit your system. Tell us your pipe size, pressure, insulation type, and connection style. Minimum order is 10 pieces. We give free samples. Custom samples take about 15 to 20 days. We take USD, EUR, GBP, and RMB. Before you buy, we help you pick the right material. After you buy, we answer your call 24/7. If it breaks within warranty and not by misuse, we send you a new one for free.
