The SERVICE METAL 3mcplhs.50 is a Class 3000 forged carbon steel half coupling designed for socket weld connections in high-pressure piping systems. Manufactured to ASME B16.11 standards and material specification ASTM A105/ASME SA105, this straight half coupling provides a reliable branch or end connection point on 0.5-inch pipe lines. At 0.28 pounds and an extra heavy (XH) wall thickness rated to Schedule 80, it delivers the mechanical strength required for demanding industrial and commercial piping applications. Licensed plumbers and pipefitters install this fitting wherever a secure, pressure-rated socket weld half coupling is needed.
This half coupling is suited for use in steam, water, oil, and gas piping systems where Class 3000 pressure ratings and socket weld end connections are specified. Its compact forged construction makes it appropriate for tight installation spaces in both commercial mechanical rooms and industrial process piping. The 0.5-inch size fits standard half-inch pipe runs requiring a branch outlet or a terminal connection point.
Designed as an OEM-style replacement or new-installation fitting for 0.5-inch socket weld piping systems requiring ASME B16.11 Class 3000 forged carbon steel half couplings.
Installation is performed by licensed plumbers or pipefitters in accordance with applicable codes, including ASME B31.1 or B31.3 as required by the system. Depressurize and isolate the piping system completely before cutting in or modifying any existing line. Socket weld fittings require proper gap clearance between pipe end and socket bottom prior to welding — follow applicable welding procedure specifications. Post-weld inspection requirements should be confirmed against project specifications and local code.
