Service Metal wn102.5 Weld Neck Flange 2.5 in 150 Lb Carbon Steel

Product Description

The SERVICE METAL wn102.5 is a 2-1/2 inch, 150 LB class weld neck flange with a raised face and standard bore, manufactured from carbon steel. Weld neck flanges are designed to be butt-welded to pipe, transferring stress to the pipe itself and providing high integrity connections suited to demanding service conditions. Weighing 11 pounds with a 7-inch outer diameter, this flange is built to ANSI/ASME B16.5 dimensional standards and is a common choice for plumbing, mechanical, and industrial piping systems where a permanent, pressure-rated flanged joint is required. Licensed pipefitters and plumbers specify this style for systems operating at moderate pressures where a reliable full-bore connection is critical.

This flange is appropriate for use in commercial and industrial piping installations, including process lines, HVAC hydronic systems, steam distribution, and general-purpose water or gas service at 150 LB pressure class ratings. Standard bore sizing ensures compatibility with Schedule 40 and similarly dimensioned pipe in 2-1/2 inch nominal pipe size. It is well suited for both new construction and retrofit applications where an existing flange connection must be matched.

Key Features

• Carbon steel construction for durability in standard-service industrial and mechanical piping
• Weld neck design transfers pipeline stress away from the flange face, reducing fatigue risk at the joint
• Raised face profile provides a focused sealing surface compatible with standard spiral-wound or ring gaskets
• 150 LB pressure class suitable for moderate-pressure steam, water, and gas service
• Standard bore sizing matches Schedule 40 pipe for consistent flow path and alignment
• 7-inch outer diameter with 11-pound construction weight typical of ANSI B16.5 dimensional conformance

Compatibility

Designed as an OEM-style replacement or new-installation weld neck flange for 2-1/2 inch nominal pipe size, 150 LB class carbon steel flanged piping systems with a raised face configuration.

Installation Notes

Installation requires a licensed pipefitter or plumber qualified to perform butt-weld connections per applicable codes such as ASME B31.1, B31.3, or local mechanical codes. The mating pipe end must be properly beveled and the bore aligned before welding to prevent stress concentrations. Depressurize and isolate the piping system completely before making any flange connection. Use only gaskets and bolting rated for the intended service pressure and temperature.
