Nibco CC09250 Polypropylene Socket Pipe Flange 3 in Sch 80

Product Description

The NIBCO CC09250 is a Schedule 80 polypropylene socket pipe flange designed for 3-inch pipe with a 7.5-inch outer diameter. This flange provides a secure, removable connection point in thermoplastic piping systems, allowing sections of pipe to be bolted together or connected to equipment. Molded in black polypropylene, it offers strong chemical resistance and durability in corrosive fluid handling applications. Licensed plumbers and pipefitters working on industrial, commercial, or chemical process systems are the primary installers. The socket-style end accepts pipe by solvent cement bonding, creating a leak-resistant joint suited to pressure-rated systems.

This flange is appropriate for use in Schedule 80 thermoplastic piping systems handling corrosive chemicals, wastewater, or industrial process fluids where metal flanges are unsuitable. The polypropylene construction makes it a common choice in chemical processing plants, water treatment facilities, and industrial facilities requiring non-metallic piping solutions. It is sized for 3-inch nominal pipe with a 7.5-inch OD flange face.

Key Features

• Schedule 80 pressure rating for thermoplastic piping systems
• Polypropylene construction provides resistance to a broad range of corrosive chemicals
• Socket-style end for solvent cement bonding to matching Schedule 80 pipe
• 3-inch nominal pipe size with 7.5-inch outer diameter flange face
• Black color molded polypropylene for UV stability and part identification

Compatibility

Designed as an OEM-style replacement or new-installation flange for 3-inch Schedule 80 polypropylene socket pipe systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic piping systems. Depressurize and drain the line completely before cutting into any existing piping. Use only solvent cement rated for polypropylene on the socket end and allow full cure time before pressurizing. Flange bolt torque should follow the system designer's specifications or the flange manufacturer's published guidelines to avoid cracking the flange face.
