Weld Neck Flange for Oil and Gas Industry

The weld neck flange is designed according to API 6A and API Spec Q1 standards. It features a neck on the side opposite the sealing face, beveled for welding directly to the pipe.

Weld neck flanges are highly valued in the oil and gas industry for their strength and reliability in high-pressure, high-temperature applications. They have a smooth bore, which facilitates inspection, cleaning, and modifications to the pipeline. The direct weld connection between the flange neck and pipe ensures a strong, leak-proof joint.

Technical Parameters:

Sizes: 1-13/16”, 2 1/16”, 3 1/16”, 4-1/16”, 5 1/8”
Pressure ratings: 3000 PSI to 15000 PSI

Recognizable by their beveled hubs, weld neck flanges are ideal for high-pressure environments and applications involving frequent bending stresses. They are connected by welding the pipe to the flange neck. Stainless steel is commonly used due to its excellent weldability, making it a preferred material for manufacturing stainless steel pipes.

The design of weld neck flanges reduces stress concentration at the hub base and effectively transfers stress from the flange to the pipe, enhancing durability and safety.
