Structural Characteristics
Split-body design:The unit consists of two semi-cylindrical halves that can be clamped directly around the leak site from the outside of the pipe, eliminating the need to dismantle the existing pipeline.
Modular sealing assembly: Composed of two metal body halves, two rubber gaskets, and matching fastening bolts and nuts; the structure is simple, allowing for convenient on-site assembly.
Material versatility: The body can be made from materials such as ductile iron, plastic-coated carbon steel, or stainless steel, while the gaskets typically utilize EPDM or NBR (nitrile rubber), offering excellent corrosion and aging resistance.
Performance Characteristics
Non-welded installation: Installation requires no hot work (welding or heat fusion) and relies solely on bolt tightening, ensuring a high safety factor.
Live repair capability:Emergency repairs can be performed without shutting down the flow of water or gas, significantly minimizing the impact of service interruptions.
Dual-sealing technology:Combines molded-contact sealing with elastic-contact sealing; the rubber gasket deforms to fill pipe irregularities and form a reliable seal, supporting a nominal pressure of up to 1.6 MPa.
Long sealing lifespan:The accompanying rubber gaskets offer a service life of up to 50 years under normal operating conditions, ensuring strong long-term operational stability.
