Lap joint flanges, ASTM A182 Lap joint flanges, Stainless Steel Lap joint flanges, ANSI B16.5 Lap joint flanges, Steel Lap joint flanges Manufacturers, Carbon Steel Lap joint flanges, Steel Lap joint flanges Suppliers in India.

The lap joint flanges with the stub end assembly is normally used in piping systems which require regular dismantling for inspection and cleaning. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End). ASTM A182 Lap Joint Flanges are similar to other types of industrial flanges, but it does not have a raised face. Lap joint flanges are used in conjunction with a “Lap Joint Stub End”.

The total initial cost of a lap joint flange along with a stub end is around one-third higher than that of comparable Blind Flanges. The backing flange is the other part of a Stainless Steel Lap Joint Flanges. This flange is all the same as any other flanges but has no raised face. To one side the left, has a slight shoulder in the middle or pipe opening. The front is flat with an external fillet in the middle to suit the fillet of the piece "Stub-end." Before the sleeve is sold to the adjacent pipe or fit, the flange part of the ANSI B16.5 Lap joint flanges is slipped onto the rear end of the sleeve. The flanges are not in any manner offered or fastened. It is free to rotate with what it joins to for correct alignment. The pressure holding capacity of lap joint flanges is comparatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flanges.
