Spears 54211185148 Van Stone Flange 10 in Cpvc Sch 80

Product Description

The SPEARS 54211185148 is a 2-piece van stone flange designed for 10-inch nominal pipe in CPVC construction. It provides a removable, rotating ring design that allows bolt holes to be aligned without rotating the pipe itself, simplifying installation in tight spaces. Rated at 150 psi at 73 degrees F, this flange is built to Schedule 80/XH wall thickness standards and uses a socket connection for solvent-welded assembly. It is manufactured domestically and suited for corrosive-fluid piping systems where standard metal flanges are not appropriate. Licensed plumbers and industrial pipefitters typically specify this flange in chemical processing, water treatment, and industrial plumbing applications.

This flange is intended for use in systems handling corrosive or high-purity liquids where CPVC thermoplastic is the preferred material. The 10-inch nominal size and 14-1/4-inch bolt circle diameter conform to standard ANSI 150-class flange bolt patterns, making it compatible with standard raised-face or flat-face mating flanges in the same class. It is commonly installed in industrial process lines, municipal water treatment facilities, and chemical distribution systems requiring pressure-rated plastic flanging. The gray color is standard for CPVC Schedule 80 fittings.

Key Features

• 2-piece van stone design allows the flange ring to rotate freely, enabling bolt-hole alignment without pipe rotation
• CPVC material provides resistance to corrosive fluids and elevated-temperature service compared to PVC
• Schedule 80/XH wall rating delivers added pressure capacity and durability
• Socket connection accepts solvent-welded Schedule 80 CPVC pipe for a permanent, leak-resistant joint
• 150 psi pressure rating at 73 degrees F suits a wide range of industrial and municipal service conditions
• Domestically manufactured in the United States

Compatibility

Designed for use with 10-inch nominal Schedule 80 CPVC pipe and standard ANSI 150-class flange hardware. The 14-1/4-inch bolt circle diameter and 16-inch outside diameter conform to standard dimensional requirements for 10-inch class 150 flanged connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC and local plumbing code requirements. Depressurize and drain the system completely before cutting into any existing line. Socket joints require proper CPVC solvent cement and primer applied according to the cement manufacturer's instructions and ASTM D2846 or F441 guidelines. Avoid over-torquing flange bolts, as CPVC is a thermoplastic and is susceptible to cracking under excessive mechanical stress.
