Built for High-Pressure Trunk Mains
The High-Pressure Pipeline Emergency Repair Clamp is made for high-pressure networks. Trunk mains, industrial high-pressure lines, and long-distance transmission pipes often run at 1.0 MPa or higher. A leak on these pipes is dangerous. The water jets out with great force. Our clamp has extra strength and sealing power for these tough conditions.
The housing wall thickness is increased by 40% over standard clamps. The housing ends and mating faces are precision-machined for tight fit. The bolts are M24 or larger with more bolts per clamp. The torque values are calculated precisely. This ensures enough clamping force to resist high pressure. The gasket has a self-energizing shape. Higher pressure pushes the gasket harder against the pipe wall. The seal gets tighter as pressure goes up. We test every clamp at 2.4 MPa for ten minutes.
We have 14 years of experience in high-pressure repair products. Our technical team can recommend the right clamp for your operating pressure and pipe size. Our products have been used in many high-pressure water projects across China. We hold ISO 9001 certification. Our quality process is strict and well-documented.
Used on a Major Water Diversion Project
A large water diversion project had a DN250 steel pipe weld leak during testing. The test pressure was 2.0 MPa. The project could not be depressurized. The repair team used our High-Pressure Pipeline Emergency Repair Clamp. They installed it under 2.0 MPa pressure.
The leak stopped. The project went into operation on schedule.
We offer a 10-year warranty. Each clamp comes with a hydro test report and material test report. Sizes cover DN50 to DN400. Larger sizes are available on request.
