Buttweld Lap Joint Stub End Fittings are mechanical joints that contain of Two components: The Stub end, that primarily a brief length of pipe, that has one finish that’s flaring outward and therefore, the alternative end ready to be welded to pipe of identical Nominal Pipe Size (NPS), material, and of an identical wall thickness. Lap joint pipe flange slide over the pipe & are most typically used with stub end fittings. A pipe is sometimes welded to the Stub end, and therefore, the lap joint pipe flange is absolve to rotate round the stub end. The good thing about lap joint stub end fittings is there’ll not be any problems with bolt hole alignment. The lap joint stub end is the fittings that are employed in place of welded flanges once the support of rotating duplicate flanges are needed. Lap Joints also named stub Ends and van stone flaring laps, it’s employed in place of welded flanges wherever rotating duplicate flanges are desired. Minimum lap thickness shall not be but nominal wall thickness. Contact faces of stub ends shall have a serration or spiral in keeping with the purchaser’s needs. These lengths and radius apply for schedule 40s or agent stainless steel pipes. Radius of fillet B is barely effective to MSS SP-43 joint stub ends.

Lap Joint Stub End Types

Lap Joint Stub end are offered in three different ways, type A, B and C. Type A and B stub end are similar to forged fittings, such as elbows and tees, and type C stub end are made in customized sizes.

Type A

The Type A lap joint Stub end is employed for standard joint flange. The lap thickness on the stub end is bigger than or up to the nominal thickness of pipe wall. Additionally, the outer corner radius of the sort A will receive the lap joint flange. The within corner is square. Lap sometimes includes a machined rough face.

Type B

The Type B lap joint Stub end is employed for standard slip on flanges as lap flanges. The lap thickness on these short ends is bigger than or up to the nominal thickness of pipe wall. Also, the outer corner radius of type B is tiny enough to receive the slip o flange which will be used as a backup flange. The inner corner is square. Lap sometimes includes a machined rough face.

Type C

The Type C lap joint Stub end will be used for standard lap joint flange, and put on flange. It’s flaring feat a rounded edge at the within diameter of the lap. If necessary, the radius will be created closed to a square. The lap thickness is 75th of the pipe wall. The sort C is very short enough to accommodate any backup flange. The lap joint on kind C is smooth, and it’s not machined.

ASME B16.9 Butt Weld Lap Joint Stub End Dimensions

Dimensions are in millimeters unless otherwise indicated. Wall thickness (t) should be nominative by client. Outlet dimension (M) for NPS and bigger is usually recommended however not needed.

Benefits of Lap Joint Stub Ends

The use of lap joint stub ends has these 2 advantages:

Reduces the price of the flanged joint

Generally, the lap joint flange is of a lower grade than the fabric of the stub end and also the wind, so saving the overall weight of best material used for the flange joint.

Example:

For associate SS316 pipe, rather than employing a full 316 welding neck flange, a mixture of associate SS316 stub end and a steel lap joint flange would do a similar actual job, however the overall weight of SS316 material would be lower, and also the price still.

Essentially, stub ends enable to reduce the burden of best material in untainted, duplex, and nickel-base alloy piping, saving prices. Of course, the larger the diameter and also the category of the flanges, the upper the saving.

Facilitates the installation of the flange

The lap joint flange is turned on the pipe and change the alignment of the bolt holes of the coupling flanges

It shall be noted that stud ends have become popular additionally in hard-hitting applications (whereas they were used for low-pressure applications only within the past).
