Stainless Steel Short Stub End

A stainless steel short stub end is a type of pipe fitting used in piping systems to connect two pipes of different sizes or materials. It is designed as a short length of pipe with one end shaped like a flange and the other end plain, allowing it to be welded to the pipe or fitting. The flange end is used to connect to a companion flange, making it easy to remove the joint for maintenance or repair. Stainless steel is used for its excellent resistance to corrosion and high temperatures, making it ideal for use in aggressive environments. Short stub ends are commonly used in petrochemical, chemical, and water treatment plants, as well as in food and beverage processing facilities.

Short Stub End Types

Short 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 Short 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 Long flange. The within corner is square. Lap sometimes includes a machined rough face.

Type B

The Type B Short 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. Short Stub End sometimes includes a machined rough face.

Type C

The Type C Short Stub End will be used for standard Long 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 Short Stub End on kind C is smooth, and it’s not machined.The lap thickness is 75th of the pipe wall. The sort C is very short enough to accommodate any backup flange. The Long Stub End on kind C is smooth, and it’s not machined.
