CPVC Flange
The CPVC Flange is a robust pipe fitting used to connect CPVC piping systems to valves, pumps, tanks, or other equipment using a bolted connection. Made from Chlorinated Polyvinyl Chloride (CPVC), the flange ensures high resistance to heat and chemicals, making it ideal for demanding industrial and chemical processing applications. It is typically used in systems requiring frequent disassembly or maintenance. The flange may be supplied with or without a metal backing ring for reinforcement and enhanced load-bearing capacity.
CPVC Flange
Key Feature of CPVC Flange
- Bolted Connection Interface: Allows for easy assembly, disassembly, and maintenance of piping systems.
- High Thermal Resistance: Performs reliably at temperatures up to 93°C (200°F).
- Excellent Chemical Resistance: Inert to a wide range of aggressive chemicals, acids, and alkalis.
- Durable Construction: Manufactured from CPVC for high strength and long service life.
- Leak-Proof Sealing Surface: Compatible with gasketed connections for tight sealing.
- Corrosion-Free Operation: Non-metallic design resists rust and corrosion in harsh environments.
- Optional Backing Ring: Can include a metal or plastic ring for additional mechanical support.
- Versatile Application: Suitable for industrial, chemical, water treatment, and HVAC systems.
