High Pressure SA350 LF6 CLASS 2 For Low-Alloy Steel Welding-Neck Flang Requiring Notch Tough RTJ Face
Flanges are used when the piping joint needs dismantling. These are used mainly at equipment’s, valves and specialties. In certain pipelines where maintenance is a regular feature, breakout flanges are provided at definite intervals. A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets and the bolting. Special controls are required in the selection and application of all these elements to attain a leak-proof joint.
Flanges can be classified based on the method of attachment to the piping as below: Welding-Neck, Slip-on, Blind, Threaded, Socket-Weld, Flat, Lap-Joint, Reducing Flange
