Lap Joints Also named Stub Ends

A lap joint stub end and its associated slip-on flange in a piping system allows quick disconnection of the particular section involved. Stub ends are installed in pairs and mated together with two lap joint flanges. The surface of the stub end has a phonographic serrated gasket surface which prevents leakage at the joint. To accommodate a lap joint stub end the flange radius is must. Using stub ends allows sections of the line to be opened for cleaning, inspection or quick replacement etc., without the need to re-weld.

If you are looking for stainless steel lap joint stub end with excellent quality, then Siddhagiri is the right source to buy stainless steel lap joint stub end.

There are two basic types of stub end, ANSI types A & B long barrel, and M.S.S. types short barrel. Under certain design criteria such as temperature or pressure, etc., it is not acceptable to have the joint between stub end and pipe in close proximity with the flange joint, in these applications ANSI types are used.

Application:

Widely used in petroleum, chemical, power, gas, metallurgy, shipbuilding and construction industries
