What are Stainless Steel Flanges?

Stainless Steel Flanges are constructed from various stainless steel materials. Stainless steel grades differ depending on the material composition, and mechanical properties vary. A flange is a forged or cast ring used to join sections of a pipe or any other machinery that requires an intermediate connecting point.

What are Weld Neck Flanges?

A weld neck flange (also known as a high-hub flange or tapered hub flange is a type of flange. It has two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in the process plants. A Weld Neck Flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.

Such flanges are suitable for use in hostile environments that have extremes of temperature, pressure, or other sources of stress. The resilience of this type of flange is achieved by sharing the environmental stress with the pipe with which it is welded. This type of flange has been used successfully at pressures up to 5,000 psi.
