Merit Brass SW3611HD-24 Half Coupling 1-1/2 in 316 Ss

Product Description

The MERIT BRASS SW3611HD-24 is a 316 stainless steel pipe half coupling rated for high-pressure service in demanding industrial and mechanical piping systems. Configured with socket weld connections on both ends, the fitting accepts pipe into a recessed socket and is then welded in place, creating a permanent, leak-resistant joint. The 316 stainless steel alloy provides superior corrosion resistance compared to 304-grade material, making it a reliable choice where chloride exposure or aggressive process fluids are a concern. At 3,000 psi pressure rating, this half coupling is suited for high-pressure process lines, steam service, and hydraulic applications requiring a compact, full-penetration welded connection.

This half coupling is used in commercial and industrial piping installations where a branch outlet or end connection is needed on a main run. Socket weld fittings at this pressure class are commonly installed in chemical processing, oil and gas, marine, and industrial utility systems. A licensed pipefitter or certified welder performs the installation, with the fitting purged and welded per applicable welding procedure specifications. The 1-1/2 inch fitting size accommodates standard Schedule pipe in that nominal diameter.

Key Features

• 316 stainless steel construction for enhanced corrosion resistance in chloride and process environments
• 3,000 psi pressure rating suitable for high-pressure steam, hydraulic, and process piping
• Socket weld x socket weld end connections for full-penetration, permanent welded joints
• 1-1/2 inch nominal fitting size for standard Schedule pipe compatibility
• Compact half coupling profile for branch outlet or end-of-run applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch nominal socket weld piping systems requiring 3,000 psi Class fittings in 316 stainless steel.

Installation Notes

Installation must be performed by a qualified pipefitter or certified welder following applicable welding codes such as ASME B31.1 or B31.3. The system must be fully depressurized and drained before any welding work begins. Socket weld fittings require a small gap between the pipe end and the socket shoulder prior to welding to allow for thermal expansion. Do not pressurize the system until all welds have cooled and have been inspected per the applicable code requirement.
