ASME Weld Neck Flange

ASME weld neck flange is a type of flange used in pipeworks to connect pipes, valves, and fittings. This flange is attached to the end of a pipe, where it provides a bolt hole pattern for bolting to another flange or to a mating flange. The most common types of ASME weld neck flanges are available in sizes ranging from 1/2 inches to 24 inches and are designed to withstand high pressure and temperature applications.

The ASME weld neck flange is designed with a neck that extends from the flange hub. This neck connects to the pipe by welding the pipe’s end to the neck’s inner bore. The flange’s hub extends outward from the neck and provides a bolting surface.

Our ASME weld neck flanges are typically made from 304 and 316 stainless steel, or alloy steel. The choice of material used in ASME weld neck flanges depends on the specific application and the fluids or gases being transported through the pipelines.

Advantages

ASME weld neck flanges offer several advantages over other types of flanges. These include:

1. High durability and strength – Weld neck flanges are designed to withstand high-pressure and high-temperature applications.

2. Better sealing capacity – ASME weld neck flanges have better sealing capacity than other types of flanges due to the larger surface area available for sealing.

3. Easy to install – ASME weld neck flanges are easy to install as they have a machined surface for precise alignment.

4. Longer lifespan – ASME weld neck flanges have a longer lifespan compared to other types of flanges due to their sturdy design.
