Steel-Plastic Coated Rubber Ring Joint 45° Elbow for Water

Key Features

• Steel-plastic composite structure: external metal reinforcement for ultra-high strength.
• Double socket design: both ends are rubber ring sockets.
• 45° smooth turn: low local resistance, smooth flow transition.
• 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 both sockets; uniform bend wall thickness.

Critical Process Parameters

• Bonding strength between metal reinforcement and PVC layer.
• Rubber ring groove accuracy on both sockets.
• 45°±1° bend angle control.

Raw Material Characteristics

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

Typical Applications

• Low-angle turns on large-diameter water supply pipes.
• Pipes following terrain slopes.
• Used in conjunction with 45° wye tees.

Application Scenarios

• 45° smooth directional changes for large-diameter water supply pipes.
