Aquatherm 3315742 Flange Ring 12 Inch Socket Weld

Product Description

The AQUATHERM 3315742 is a 12-inch flange ring designed for use with Aquatherm Green Pipe polypropylene piping systems. It provides a secure, leak-resistant bolted connection between pipe segments or at equipment termination points. Constructed from a polypropylene and steel composite, this flange ring uses a socket weld connection type and is built to the dimensional standards required for 12-inch nominal pipe applications. With an inside diameter of 13.4 inches and an outside diameter of 19 inches, it accommodates the full bore of the pipe while providing a robust mechanical interface. Licensed plumbers and mechanical contractors are the typical installers for this fitting.

This flange ring is intended for use in commercial and industrial mechanical piping systems where Aquatherm Green Pipe is specified. It is well-suited for hydronic heating and cooling distribution, chilled water systems, and process piping applications. The socket weld design allows the pipe to be fused directly into the flange ring using standard polypropylene heat fusion tooling. The green finish is consistent with the Aquatherm Green Pipe product line, aiding in system identification during installation and inspection.

Key Features

• 12-inch nominal size with a 13.4-inch inside diameter and 19-inch outside diameter
• Socket weld connection for heat fusion compatibility with polypropylene pipe
• Polypropylene and steel composite construction for structural rigidity and chemical resistance
• 17-inch bolt circle diameter with 12 bolt holes at 1-inch diameter each
• 0.88-inch flange thickness provides a stable sealing surface
• Green finish for visual identification in Aquatherm Green Pipe systems

Compatibility

Designed as an OEM-style component for use with 12-inch Aquatherm Green Pipe polypropylene piping systems using socket weld heat fusion connections.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor familiar with polypropylene heat fusion procedures and applicable codes including the IPC and ASME B31.9. The piping system must be fully depressurized and drained before flange work begins. Use appropriate heat fusion tooling sized for 12-inch pipe when seating the pipe into the socket weld end. Verify bolt torque patterns and gasket selection against the project engineer specifications prior to final assembly.
