Built for Buried Pipe Conditions
The Underground Pipeline Emergency Repair Clamp is made for buried pipe repairs. Underground leaks are the most common and most damaging type in water networks. Repairs involve excavation, dewatering, and working in confined spaces. The environment is wet, muddy, and corrosive. Our clamp is designed for these harsh conditions.
The housing walls are thick enough to handle soil loads. Even under deep burial, the housing does not deform. The gasket uses a wear-resistant EPDM compound. It performs well even in sandy water. The epoxy coating is twice as thick as our standard coating. This gives excellent corrosion resistance for long-term burial. The bolts have Dacromet anti-rust treatment. They stay removable even after years underground. This makes future pipe maintenance possible.
We hold ISO 9001, ISO 14001, and ISO 45001 certifications. Our factory follows strict environmental and safety standards. We test every clamp for coating thickness and pressure resistance. Each clamp comes with a salt spray test report and coating thickness report.

Reduced Repair Failure Rate by 90%
A coastal city's water network is buried in reclaimed land with high salt content. Pipe corrosion is severe. Underground leaks happen often. The city water company switched to our Underground Pipeline Emergency Repair Clamp. Their repair failure rate dropped from 15% to under 1%.
They excavated some clamps for inspection after two years. The coating was intact. The bolts turned freely. The gaskets were still elastic.
We offer a 10-year warranty. Sizes cover DN50 to DN400. We can customize for deep burial and special soil conditions.
