Kencotube is a pioneer manufacturer & suppliers of Duplex Steel Lap Joint Flanges in India, which is very similar to a slip-on flange, with the main difference being that it has a curved radius at the bore and face to house a lap joint stub-end. Duplex Steel Lap Joint Flanges in India are characteristically used in circumstances where recurrent dismantling is essential for the inspection. Super Duplex Steel Lap Joint Flanges look very similar to Slip-On flanges but the actual main difference is that the threaded flange has been was bored out to match a specific pipe inside diameter. The backside of the center opening in Duplex Steel Lap Joint Flanges is counterbored to form the appropriate size socket to take the pipe outside diameter.
The diameter of the smaller bore in Duplex Steel Lap Joint Flanges is the same as the inner diameter of the matching pipe. A restriction is built into the bottom of the bore in Duplex Steel Lap Joint Flanges, which sets as a shoulder for the pipe to rest on. Super Duplex Steel Lap Joint Flanges can be used in very high-pressure services and their major advantage is that they can be assibled without welding. Duplex Stainless Steel Lap Joint Flanges itself is not welded or fixed in any way. It is free to spin for proper alignment with whatever it is joining. The contact surfaces in these Super Duple Steel Lap Joint Flanges do not match and there is no gasket that has one type on one side and another type on the other side.
Duplex Steel Lap Joint Flanges are similar to other types of industrial Flanges, but it does not have a raised face. Duplex Steel Lap Joint Flanges are used in conjunction with a “Duplex Steel Lap Joint Stub End”. The total initial cost of a Duplex Steel Lap Joint Flanges along with a stub end is around one-third higher than that of comparable welding neck Flanges. The pressure holding capacity of Duplex Steel Lap Joint Flanges is comparatively lower, and the fatigue life for the assembly is only one-tenth that of welding neck Flanges. These Flanges are offered at custom-made sizes and shapes to our valued patrons.
The Duplex Steel Lap Joint Flanges with the stub end assembly is normally used in piping systems that 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 Flanges against the back of the pipe lap (Stub End).
