Steel-Plastic Coated Rubber Ring Joint Equal Tee for Water

Key Features

• Steel-plastic composite structure: external metal reinforcement for ultra-high strength.
• Triple socket design: all three ports are rubber ring sockets with full rubber ring sealing.
• Equal diameter branch: main and branch have same diameter, no flow loss.
• Large diameter capability: maximum diameter up to 1200mm.

Manufacturing Process

Internal UPVC layer formed by injection molding or welding; external metal reinforcement coating. Rubber ring grooves machined in all three sockets; reinforced junction structure.

Critical Process Parameters

• Bonding strength between metal reinforcement and PVC layer.
• Rubber ring groove accuracy on all three sockets.
• Coaxiality and perpendicularity control of all ports.

Raw Material Characteristics

• Inner layer: UPVC
• Outer layer: Steel or ductile iron
• Sealing rings: EPDM

Typical Applications

• Branch distribution on large-diameter municipal water mains.
• Pipe branching in large pump stations and water plants.

Application Scenarios

• Equal diameter tee branch connections for large-diameter water supply pipes.
