Flanged Joint

Flanged joints are generally used at locations where it becomes necessary to disjoint the pipe off and on, like as at pumping stations, filter plants and etc. Cast iron pipes which are to be joined with flanged joints are cast with heavy flanges at both ends whereas in case of steel pipes, flanges are separately cast and screwed or welded at both ends of the pipe length.

The flanges are put together and a rubber washer known as gasket is kept between flanges and fixed by means of nuts and bolts. The gasket is not less than 1.5 mm thick.

The joints are rigid, strong and simple to repair.
