Stub End is basically fittings which replace welded flanges when you need rotating backup flanges. Another name of Stub Ends is Lap joints and Vanstone Flared Laps. Stub end are born from adaptable materials from the designed piping systems. Although, the backup flanges need not be made from the same ingredient.
Fittingcart manufactures the best stub end in the world. Well, you must be wondering how the stub ends work? Firstly, a pivoting backup flange is placed against the backside of the stub end. Now, when you add bolts, they start clamping which presses the pivoting backup flange against the back of stub end. Further, this leads to the gasket surface of the stub end pressing against a gasket and another gasket surface. Hence, supplying joints like standard flange joints. Hence, the gasket surface of the stub end alone makes the seal whereas the flange just supplies the clamping pressure on the joint.

The correlated slip on the flange and the lap joint stub end helps you in faster detachment of a specific sector in the piping system. First, the stub end are set up in pairs and breed together along with two lap joint flanges. However, the surface of the stub ends has a phonographic jagged gasket surface base to prevent leakage at the joint. The major advantage with stub end is that they allow a section of line to open when inspecting or cleaning and substituting, hence avoiding the need of re-welding. A.S.A long barrel and M.S.S. short barrel are two types of lap joint stub ends. Strangely enough, it is not precise to have a joint between stub end and pipe in short or close concurrence with the flange joint under some design qualifications like pressure or temperature. Hence, in such applications A.S.A. types are useful.We at Fittingcart, manufacture high-quality stub ends of long & short radius to MSS and ANSI B 16.9 standard.
