Key Features
- Double socket structure: both ends are rubber ring sockets sealing against pipe spigots.
- Straight connection: used for extending two UPVC pipes of the same diameter.
- Rubber ring seal: quick installation without solvent cement or curing time.
- Flexible connection: accommodates minor ground settlement and pipe movement.
Manufacturing Process
Coupler body manufactured via high-precision injection molding. Both socket ends have machined grooves for rubber rings. A center stop ring limits pipe insertion depth.
Critical Process Parameters
- Coaxiality control of both sockets.
- Rubber ring groove dimensional accuracy.
- Socket ID and ovality control.
- Stop ring positioning accuracy.
Raw Material Characteristics
- Material Composition: Unplasticized Polyvinyl Chloride (UPVC), sanitary-grade resin, no plasticizers. Sealing rings: EPDM.
- Material Properties: High mechanical strength and rigidity. Outstanding chemical resistance. Suitable for cold water ≤45°C. Complies with potable water standards.
Typical Applications
- Straight extension connections in municipal water supply networks.
- Pipe joining in industrial water supply pipelines.
- Pipe splicing in agricultural irrigation systems.
- Quick connection of buried water supply pipes.
Application Scenarios
- Straight extension connections in UPVC water supply systems.
