UPVC Lap Joint Flange for Industry

Key Features of UPVC Lap Joint Flange for Industry

• Lap joint design: has a flange ring that rotates freely for precise bolt hole alignment.
• Solvent cement connection: the stub end is permanently bonded to the UPVC pipe via solvent cement.
• Detachable: allows easy maintenance and replacement of valves or equipment.
• Corrosion resistant: fluid contacts only the UPVC stub end; the flange ring can be metal.

Manufacturing Process of UPVC Lap Joint Flange for Industry

For each, the stub end is injection molded from UPVC. The flange ring can be UPVC, PP, or metal (carbon steel, stainless steel). The ring slides over the stub end and presses against the back of the flare.

Critical Process Parameters of UPVC Lap Joint Flange for Industry

Every is checked against these parameters:

• Precise stub end socket machining.
• Flatness and perpendicularity control of flare face against flange ring contact surface.
• Flange ring bolt circle and hole diameter conform to standards.

Raw Material Characteristics of UPVC Lap Joint Flange for Industry

• Stub end: UPVC (PVC-C version available for high-temperature use)
• Flange ring: UPVC, PP, or metal (galvanized carbon steel, stainless steel)
• Gasket: EPDM
• UPVC suitable up to 60°C; PVC-C suitable up to 93°C

Typical Applications of UPVC Lap Joint Flange for Industry

• The fitting connects chemical piping to metal flanged valves.
• The fitting connects to flanged equipment such as corrosion-resistant pumps and filters.
• The fitting provides transition connections between plastic pipes and metal pipes or dissimilar plastic pipes.

Application Scenarios of UPVC Lap Joint Flange for Industry

• Connection of UPVC piping to pump inlets/outlets in pump rooms — is the standard fitting for these transitions.
• Installation of metal flanged valves on chemical piping — provides a reliable detachable joint.
