Description:

Flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework systems. It also provides easy access for cleaning, inspection or modifications. Flanges are usually welded or screwed int such systems and then joined with bolts.It is the machinery, petroleum, chemical, water, electricity, shipbuilding sectors piping systems and devices most widely used pipe fittings.

Slip on weld flanges are slipped over the pipe and welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on Flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe to length. These SO flanges can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube.
