No-Heat Repairs for Polyethylene Pipes
The PE Pipe Repair Clamp is made for fast fixes on polyethylene water mains. PE pipes are popular in city supply, gas lines, and rural water projects. But when they leak, traditional heat fusion takes time – you must drain, dry, and cool the joint. This clamp installs under pressure with water still flowing, saving hours.
The seal is optimized for PE's soft surface. Our EPDM gasket is flexible and gentle – it seals tightly without scratching the pipe. The QT450 ductile iron housing is strong and impact-resistant, handling pressure surges. One worker can install it in about 20 minutes without electricity or special equipment.
We have a 3,500 m² workshop with our own R&D team and patents. Our epoxy spray line gives each clamp a uniform, dense coating that resists acids, alkalis, and moisture. We supply tens of thousands of these clamps to water groups every year, building deep application experience.

Reliable Performance in PE Networks
The housing and 8.8-grade bolts give high mechanical strength and fatigue resistance. The epoxy coating passes adhesion and salt spray tests for long-term corrosion protection. The EPDM rubber resists aging, ozone, and many chemicals for over 10 years.
In a northern Chinese city, a DN315 PE main burst threatened 50,000 households. The repair team used our clamp and fixed it in 50 minutes – avoiding a huge water outage. They received official commendation. This real example confirms the clamp's effectiveness. We include detailed installation guides and accept third-party inspections for your confidence.
