Frequently Asked Questions
What pipe types and sizes is the Straight Pipe Repair Clamp for Steel Pipe compatible with?
The Straight Pipe Repair Clamp for Steel Pipe fits DN125 to DN1400 pipelines and is engineered for carbon and galvanized steel. 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 Straight Pipe Repair Clamp for Steel 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 / carbon steel · 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.
