Merit Brass SW3611HD-32 Pipe Half Coupling 2 in 316 Ss

Product Description

The MERIT BRASS SW3611HD-32 is a 2-inch pipe half coupling designed for socket weld installations in high-pressure piping systems. Machined from 316 stainless steel, this fitting delivers a pressure rating of 3,000 psi and resists corrosion in demanding process, industrial, and commercial plumbing environments. A half coupling provides a single female socket end for branch connections to pipe or fittings, making it a standard component in fabricated piping assemblies. Licensed pipefitters and industrial plumbers select this fitting when a full coupling is not required or where space constraints limit the installation envelope.

This fitting is suited for use in process piping, steam lines, chemical distribution, and other high-pressure systems where 316 stainless steel is specified for corrosion resistance. The socket weld end connection accepts standard pipe inserted into the socket bore before fillet welding, producing a smooth internal bore with minimal turbulence. It is commonly used in both new construction and retrofit piping projects across industrial, commercial, and heavy mechanical applications.

Key Features

• 316 stainless steel construction for superior corrosion resistance in aggressive media
• 3,000 psi pressure rating supports high-pressure piping system requirements
• Socket weld end connection on both fitting ends for secure fillet-welded joints
• 2-inch fitting size for standard pipe branch or inline connections
• Half coupling design reduces material where only one socket end is needed

Compatibility

Designed as an OEM-style replacement or new-install component for 2-inch socket weld piping assemblies requiring a 3,000 psi rated 316 stainless steel half coupling.

Installation Notes

Installation should be performed by a qualified pipefitter or licensed plumber in accordance with applicable codes such as ASME B16.11 and the applicable sections of the IAPMO or local mechanical codes. Depressurize and drain the piping system fully before cutting into any existing line. Socket weld fittings require the pipe to be inserted into the socket bore with a small gap per ASME welding procedures before fillet welding by a qualified welder. Do not use threaded tools or excessive force that could distort the socket bore prior to welding.
