Penn Machine 4971301601 Insert 3x1-1/2 in Socket Weld 3000 Lb

Product Description

The PENN MACHINE 4971301601 is a forged carbon steel insert fitting designed for socket weld connections in high-pressure piping systems. Part of the Series 13016 product line from Pennsylvania Machine Works, this insert carries a 3000 lb pressure class and a Schedule 80/XH rating, making it suitable for demanding industrial and commercial pipe installations. The fitting measures 3 x 1-1/2 inches nominal with a 3-1/2 inch OD and weighs 3.927 pounds. Licensed pipefitters and industrial mechanical contractors work with this class of fitting in process, utility, and plant piping applications where pressure integrity and material traceability are required.

This insert is intended for use in socket weld piping assemblies operating at elevated pressures. The 3000 lb class rating and SCH 80/XH schedule compatibility make it appropriate for steam, hydraulic, and process fluid systems in both industrial plant and commercial mechanical environments. The forged carbon steel construction meets ASME B16.11 and ASTM A105 standards, and the fitting carries PED Certification as well as Canadian Registration in all provinces, supporting cross-border project compliance.

Key Features

• 3000 lb pressure class with Schedule 80/XH rating for high-pressure piping service
• Forged carbon steel construction meeting ASTM A105 material requirements
• Socket weld end style for full-penetration weld connections
• 3-1/2 inch OD on a 3 x 1-1/2 inch nominal size
• ASME B16.11 compliant forged fitting geometry
• PED Certified and Canadian Registered in all provinces for broad project compliance

Compatibility

Designed for socket weld piping systems rated at 3000 lb pressure class with Schedule 80/XH pipe. Compliant with ASME B16.11 and ASTM A105, making it compatible with standard forged carbon steel socket weld assemblies in industrial and commercial mechanical piping.

Installation Notes

Installation should be performed by a qualified pipefitter or certified welder in accordance with applicable codes including ASME B31.1 or B31.3 depending on the service classification. De-pressurize and isolate the piping system completely before fitting installation. Socket weld connections require proper gap spacing between pipe end and fitting socket shoulder before welding to allow for thermal expansion. Follow applicable welding procedure specifications and inspection requirements for the service type.
