FLANGE
What is a Flange ?
A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
Types Of Flanges
Weld Neck Flange
Slip on Flange
Socket Weld Flange
Threaded Flange
Lap Joint Flange
Blind Flange
