Penn Machine 5981301601 Socket Weld Insert 4x3 in 3000 Lb

Product Description

The PENN MACHINE 5981301601 is a forged carbon steel socket weld insert designed for high-pressure piping systems. Manufactured to SCH 80/XH schedule rating and rated at 3000 lb pressure class, this insert is built for demanding industrial and commercial piping applications. The 4 x 3 inch nominal size fitting features a 4-1/2 inch OD and is produced by Pennsylvania Machine Works under Series 13016. Installation is performed by licensed pipefitters and plumbers working on high-pressure process or utility lines where joint integrity and pressure rating are critical.

This insert is suited for industrial process piping, steam systems, and high-pressure utility lines where socket weld connections are specified. The 3000 lb pressure class rating makes it appropriate for applications requiring elevated pressure resistance. It conforms to ASME B16.11 and ASTM A105 standards and carries PED Certification along with Canadian Registration in all provinces, making it suitable for both domestic and Canadian job sites.

Installation Notes

Installation of socket weld fittings should be performed by a qualified pipefitter or licensed plumber in accordance with applicable codes including ASME B31.1 or B31.3 as required by the system. Depressurize and isolate the line completely before beginning work. Socket weld joints require proper fit-up and certified welding procedures — do not substitute fillet weld size or skip post-weld inspection steps required by the governing code. Verify pressure class and schedule compatibility with the connected piping before installation.
