Built for High-Pressure Networks
The High Pressure Pipe Repair Clamp handles leaks on high-pressure water mains. Some city trunk lines run at 1.6 MPa or higher. Standard clamps may fail under these pressures. Our clamp uses thicker walls, bigger bolts, and a stronger seal design. It holds tight even under high operating pressure.
The housing walls are 30% thicker than our standard models. The bolt size and bolt count are increased. More bolts spread the clamping force more evenly. The gasket has a self-energizing design. Higher water pressure pushes the gasket harder against the pipe wall. The seal actually gets tighter as pressure goes up. We test every clamp at 2.4 MPa for ten minutes. This is well above the normal working pressure. The test record comes with each product.
We hold ISO 9001, ISO 14001, and ISO 45001 certifications. Our products are tested by the Shanghai Institute of Quality Inspection. The tests include housing strength and seal performance. Our quality team uses stricter standards for high-pressure products. Each clamp has its own pressure-time test curve. You can trace the test data through our records.
Reliable Under Extreme Conditions
A chemical plant had a cooling water leak at 1.4 MPa. The pipe was steel and had a weld crack. They could not shut down the process. They used our High Pressure Pipe Repair Clamp as a trial. The team installed it without reducing pressure. The leak stopped immediately. After three months of monitoring, there was no sign of leakage. The plant now keeps our clamps as standard emergency stock.
The housing uses reinforced QT450 ductile iron. The epoxy coating is cured at high temperature. This gives better adhesion and corrosion resistance. The gasket uses a high-pressure EPDM compound. It has higher hardness and better extrusion resistance. The bolts are oversized 8.8 grade with anti-loosening washers.
