Fibre-metal 69029109136 90 Degree Elbow 4 in 3000lb Sw

Product Description

The FIBRE-METAL 69029109136 is a 4-inch, 3000-pound class forged steel socket weld 90-degree elbow rated to ASTM A105 carbon steel material specifications. This fitting redirects piping flow at a 90-degree angle in high-pressure socket weld piping systems. The socket weld end configuration accepts pipe into a recessed socket before fillet welding, producing a strong, leak-resistant joint suitable for demanding service conditions. Licensed pipefitters and welders install this type of fitting in industrial, commercial, and mechanical piping applications where reliable directional changes are required.

This elbow is suited for use in high-pressure piping systems operating in industrial plants, refineries, mechanical rooms, and commercial facilities. The 3000-pound pressure class makes it appropriate for moderate to high-pressure steam, water, oil, and gas service lines. The 4-inch nominal pipe size fits standard Schedule 80 or heavier pipe in socket weld configurations. Installations typically occur in process piping, HVAC hot-water systems, compressed air headers, and similar fluid-handling systems requiring durable forged fittings.

Key Features

• 4-inch nominal pipe size for socket weld installation
• 3000-pound pressure class rating for high-pressure service
• ASTM A105 forged carbon steel construction for strength and durability
• 90-degree elbow geometry for right-angle directional changes in piping runs
• Socket weld end connection for fillet-welded, leak-resistant joints

Compatibility

Designed as an OEM-style forged steel socket weld fitting compatible with 4-inch nominal pipe in 3000-pound class socket weld piping systems conforming to ASTM A105 carbon steel material standards.

Installation Notes

Installation of socket weld fittings must be performed by a qualified, certified pipefitter or welder in accordance with applicable codes including ASME B31.1, ASME B31.3, or the governing piping code for the service. Depressurize and isolate the piping system completely before cutting and fitting any components. Insert pipe to the full socket depth, then pull back approximately 1/16 inch before tack welding to allow for weld shrinkage. Follow applicable welding procedure specifications and inspection requirements for the pressure class and service fluid.
