What is a Flanges? What are the Various Types of Flanges?
A flange is type of fitting used to connect pipes, valves, pumps and other equipment to form a piping system. A flanged joint involves three separate components; the flanges, the gaskets, and the bolting. One of the most important advantage of using a flange is that it allows more flexibility in maintenance.
The various types of flanges include: Weld neck Flanges (WNRF), Slip-on Flanges (SORF), Blind Flanges (BLRF), Lap Joint Flanges, (SOLJ), Socket-weld Flanges (SWRF), Screwed (Threaded) Flanges, Long weld neck Flanges (LWNRF), Spectacle Blind Flanges, Spacer & Blind Flanges, Ring Type Joint Flanges (RTJ), Reducing Flanges, Raised Face (RF) Flanges, Orifice Flanges, Large Diameter Flanges, Custom Flanges, Drawing Flanges, Forged Flanges, Plate Flanges, Flat Face Flanges, etc.
