Frequently Asked Questions
What pipe types and sizes is the Direct Repair Clamp for PE Pipe compatible with?
The Direct Repair Clamp for PE Pipe fits DN50 to DN315 pipelines and is engineered for PE (HDPE). It seals longitudinal cracks, pinholes, circumferential fractures, and joint leaks without cutting out the damaged pipe section.
What is the working pressure rating?
Rated for 1.0 MPa. Standard clamp bodies are tested to at least PN16 (1.6 MPa); higher-pressure variants are available on request for gas-distribution and industrial service.
Can this clamp be installed on a live, pressurized pipeline?
Yes. The Direct Repair Clamp for PE Pipe is designed for installation on live pipelines under pressure, which means municipal water, gas, or process flow does not have to be interrupted. Our technical team provides pre-install checklists to ensure safe deployment.
What materials are used in the body and sealing gasket?
Construction — shell: Ductile iron QT450-10 · seal: EPDM. Corrosion-resistant stainless-steel banding (SUS304 / SUS316) with EPDM (potable water) or NBR (oil / hydrocarbon service) gaskets is available depending on the application.
What is the lead time and how is it shipped?
