Merit Brass SWM611-24 Pipe Coupling 1-1/2 in 316 Ss Sw

Product Description

The MERIT BRASS SWM611-24 is a 1-1/2 inch socket weld pipe coupling manufactured from 316 stainless steel and rated to 150 psi. Couplings in this configuration join two sections of same-diameter pipe by accepting each pipe end into a recessed socket, which is then fillet-welded to create a permanent, leak-resistant joint. The 316 stainless steel alloy provides elevated corrosion resistance compared to 304 grade, making this fitting well suited for chemically aggressive or high-moisture service environments. Licensed plumbers, pipefitters, and industrial piping contractors are the typical installers of socket weld fittings of this type.

This coupling is used in commercial and industrial piping systems where a socket weld end connection is specified. Common applications include process piping, chemical handling lines, food and beverage systems, and marine or coastal installations where chloride exposure is a concern. The 1-1/2 inch fitting size places it in a range frequently encountered in mechanical room headers, pump discharge lines, and process distribution manifolds. It is sold individually as a single unit.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh and chemically aggressive environments
• Socket weld by socket weld end connections for a permanent, full-penetration fillet weld joint
• 150 psi pressure rating suitable for a broad range of commercial and industrial service conditions
• 1-1/2 inch fitting size for mid-range pipe diameter applications
• Single-unit packaging allows procurement of exact quantities needed

Compatibility

Designed as an OEM-style replacement or new-installation socket weld coupling for 1-1/2 inch piping systems specified for 316 stainless steel fittings at 150 psi service ratings.

Installation Notes

Socket weld fittings must be installed by a qualified pipefitter or welder following applicable codes such as ASME B31.3 for process piping. Depressurize and drain the line completely before cutting or fitting any pipe section. The pipe end should be fully inserted into the socket and then backed out slightly before tack welding, as required by standard socket weld procedure, to allow for weld shrinkage. Do not use this fitting beyond its rated pressure without consulting the system engineer of record.
