Schedule 80 CPVC Flanges

Schedule 80 CPVC flanges are used to create a secure, leak proof connection between pipes, valves, pumps, and other equipment to complete a piping system. Flanges have a compact, flat disc shaped design that helps minimize space requirements in tight installations. They include bolt holes for securing with bolts and often use gaskets or O-rings to create a tight seal. CPVC flanges are available in solid, van stone, and blind fitting types. The bolted connection of Schedule 80 CPVC flanges provides easy disassembly and reassembly, which allows for maintenance and repairs of specific components without needing to dismantle the entire system. Their unique installation also enables easy addition or modification of components like valves, pumps, and instruments within a plumbing system. 

Schedule 80 CPVC flanges are made from durable and corrosion resistant CPVC thermoplastic material that is suitable for a variety of environments and applications. CPVC flanges are also known as heavy duty flanges, industrial flanges, and high pressure flanges. They have thicker walls than standard Schedule 40 fittings to provide increased strength and rigidity. These characteristics make Sch 80 CPVC flanges rated for systems with high fluid pressure requirements, risk of pressure surges, high temperatures, or other mechanical stresses. CPVC plastic is rated for operational temperatures up to 200°F (93°C) making the flanges approved for handling hot liquids. Heavy duty CPVC flanges are commonly used in high pressure or demanding conveyance systems such as chemical processing, water treatment, manufacturing, and industrial work processes.

Sch 80 PVC flange sizes range from 1/2" to 12” in plumbing diameter. CPVC flange products are available in solid flange, van stone flange, and blind flange fittings. Sch 80 flanges come in either socket, threaded, spigot, or blind bolted connection options.

Solid CPVC flanges are either slip-on flanges or threaded flanges. Van stone CPVC flanges feature a free-moving ring that rotates to allow for easier installation and have either spigot or socket connection types. Blind CPVC flanges have a bolted flat end and are used to terminate pipe lengths similar to caps or plugs.

Our Schedule 80 CPVC flanges are USA made and engineered. They are precision manufactured using modern production practices and materials to meet the top industry standards for technical specifications and performance. CPVC Schedule 80 flanges meet ASTM D1784, ASTM F439, ASTM F437, and NSF standards for long term reliability, quality, and safety. 

Standard ASTM D1784 guarantees the base CPVC material has the correct composition and classification for purity, strength, and chemical resistance. Standards ASTM F439 and ASTM F437 specify requirements for fitting connections, dimensions, and pressure ratings per Schedule 80 sizing. Our CPVC Schedule 80 flanges are NSF certified and approved safe for use in potable water applications.

CPVC is a thermoplastic material that has compatibility with many commonly used industrial, manufacturing, and commercial chemicals, materials, and ingredients. Chemical compatibility should always be verified before installing and using any plumbing lines for chemical conveyance systems.

Schedule 80 CPVC flanges are widely used in plumbing systems and CPVC pipe networks across various industries. They are particularly suited for applications involving corrosive chemicals, reactants, hot liquids, or high pressure networks, making them ideal for use in the chemical processing industry. In commercial, industrial, and manufacturing settings, Schedule 80 CPVC flanges are used to create secure connections between distribution systems and equipment. They are also installed in large scale irrigation systems to maintain reliable connections, even under high pressure conditions, while allowing disassembly for system maintenance or modification. In water treatment and wastewater management, Schedule 80 CPVC flanges are essential for handling systems with high water pressure and exposure to treatment chemicals.
