ASTM SCH40 & SCH80 PVC-U/C Integral Flange

Key Features

• ASTM SCH40/SCH80 compliant: meets ASTM wall thickness and pressure rating requirements.
• One-piece molding: seamless flange and adapter, high strength, no leak paths.
• Solvent cement joint: permanent fusion with PVC-U/C pipe.
• Fixed flange: non-rotating bolt holes for nodes not requiring frequent disassembly.

Manufacturing Process

One-piece injection molding from PVC-U/C. Flat flange face and precise socket dimensions. Bolt holes distributed per ASTM standards.

Critical Process Parameters

• Flange face flatness and perpendicularity conforming to ASTM tolerances.
• Bolt circle and hole diameter conform to ASTM standards.
• Precise socket machining.

Raw Material Characteristics

• Material Composition: PVC-U or PVC-C, conforming to ASTM D1784.
• Material Properties: PVC-U suitable ≤60°C; PVC-C suitable ≤93°C.
• SCH40/SCH80 wall thickness options available.
• High mechanical strength and internal pressure resistance.

Typical Applications

• Fixed connections to flanged equipment in ASTM chemical piping.
• Flanged connections in industrial water treatment systems.
• Pipe connections in electroplating and semiconductor industries.

Application Scenarios

• Fixed connections between ASTM industrial piping and flanged equipment.
