These Lapped Joint Flange are manufacture in different Material of Flanges like SORF Flanges, Carbon Steel Lapped Joint Flanges, Stainless Steel Lapped Joint Flanges, Alloy Steel Lapped Joint Flanges, Duplex Steel Lapped Joint Flanges, Inconel Lapped Joint Flanges, Monel Lapped Joint Flanges, Hastelloy Lapped Joint Flanges, Copper Nickel Lapped Joint Flanges in India & Asia, conform to Slip On specifications.
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 welding neck flanges. 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.The lap joint flange 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).
