A flange is an external or internal ridge, or rim, for strength, such as the support mechanism of an iron beam like an I-beam or T-beam.


Flanges are used for strengthening and connecting supports or attachments, for example for helping a wheel maintain a position on a rail. Flanges are welded together or screwed on at a joint providing a seal.

They can typically be found employed by the petrochemical industry and the oil and gas industries, but they are also implemented in the plumbing, mechanics, and electronics industries.

Flanges are designed to withstand various ranges of pressure and weight and come in a spectrum of types, like slip-on, blind, weld-neck, threaded, socket weld, lap joint, and orifice. They help prevent pipe leakage, as the prices of oil and gas continuously increase.


Enforcing any means to procure and save these precious and unrenewable resources is imperative, which is why Process Pipe fabricates and manufactures flanges in a variety of materials, shapes, and sizes to meet your specific construction needs.
