Frequently Asked Questions
What pipe types and sizes is the Sleeve Repair Clamp for DI Pipe compatible with?
The Sleeve Repair Clamp for DI Pipe fits DN80 to DN1200 pipelines and is engineered for ductile iron and grey cast 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 Sleeve Repair Clamp for DI 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?
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.
