Steel-Plastic Coated Rubber Ring Joint Saddle Clamp for Water

Key Features

• Steel-plastic composite structure: external metal reinforcement for ultra-high clamping force and strength.
• Hot tap capable: can be operated under pressure with a tapping tool.
• Saddle design: tightly conforms to main pipe exterior for reliable sealing.
• Large diameter capability: main pipe diameter up to 1200mm.

Manufacturing Process

Internal UPVC layer conforms to main pipe; external metal reinforced saddle. EPDM gasket on inner surface; bolted tightening. Branch outlet available as rubber ring socket or flange.

Critical Process Parameters

• Fit accuracy between metal reinforced saddle and gasket.
• Matching accuracy between saddle inner arc and main pipe OD.
• Gasket compression and sealing performance.

Raw Material Characteristics

• Inner layer/Gasket: UPVC/EPDM
• Outer saddle: Steel or ductile iron
• Fasteners: Stainless steel

Typical Applications

• Online branch addition on large-diameter water mains.
• Pressurized service line connections.
• Post-installation of reserved branch interfaces.

Application Scenarios

• Online branch connections on large-diameter water supply pipes.
