Frequently Asked Questions
What pipe types and sizes is the Reducing Straight Pipe Repair Clamp compatible with?
The Reducing Straight Pipe Repair Clamp fits OD90 to OD315 pipelines and is engineered for PE (HDPE), PVC, PPR, and ductile iron. 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 Reducing Straight Pipe Repair Clamp 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: 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?
Standard lead time is 15 working days ex-factory, shipping FOB Shanghai. Sea, air, and combined transport are arranged through PipeKnot to over 40 countries. Volume orders and project tenders receive priority scheduling.
Is installation guidance and technical support included?
PipeKnot provides English-language installation drawings, torque specifications, and remote technical support. On-site commissioning support can be arranged for qualifying projects in partnership with Anhui Tongfa field engineers.
