Inline Pressure Balanced Expansion Joint

Our Inline Pressure Balanced Expansion Joint is made for long pipelines, heat networks, and chemical plants. We have been doing this for over 20 years. This inline pressure balanced expansion joint takes in axial moves and balances the inside pressure thrust at the same time. It helps you spend less on pipe supports. We use 316L or 321 stainless steel for the bellows. The balance part uses high-strength alloy steel with a tensile strength over 550MPa.

This thing works from -20℃ to 650℃. It handles pressures from PN6 to PN100. Each inline pressure balanced 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 12,000 cycles. It stands up to high pressure, high heat, and corrosion. It protects valves, pumps, and flanges. Our factory is 10,000 square meters with 50 workers. We check every unit before shipping. We give a 24-month warranty.

Long distance, high pressure, and big pipes are all different. So you can adjust this inline pressure balanced expansion joint to your needs. Tell us your pipe size, pressure, connection type, and special conditions. Minimum order is 10 pieces. We give free samples. Custom samples take about 15 to 20 days. We take USD, EUR, GBP, and RMB. After you order, we update you every day. If there is a problem, we tell you right away. No hiding, no delaying.
