Weld Neck Flanges
High-pressure flanges welded directly onto the pipe, with a long tapered neck that reinforces the joint.
Ideal for high-pressure applications, weld neck flanges are designed to be welded directly onto the pipe, ensuring a strong, leak-proof connection.
Their long neck provides reinforcement and reduces stress at the joint, transferring load from the flange into the pipe wall — which is why they are specified for cyclic, high-temperature and high-pressure duty.
Materials
- Stainless steel
- Carbon steel
- Alloy steel
Key features
