Product Description

High Pressure Pipe Flanges Alloy Steel Weld Neck Pipe Flanges , 2500 # Astm A182 F9 F91 High Pressure Pipe Flanges

A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term "flange" is also used for a kind of tool used to form flanges.
