A stainless steel long stub end is a type of fitting used in piping systems to connect two sections of pipe or tubing. The long stub end is typically used in applications where the piping system needs to be easily disassembled or in situations where the pipe needs to be cut and reconnected at a later time.
Stainless steel is a popular material for long stub ends because it is corrosion-resistant, durable, and can withstand high temperatures and pressures. This makes it suitable for use in a variety of industries, including chemical processing, oil and gas, and food and beverage.
The design of a stainless steel long stub end consists of a short length of pipe with a flange on one end and a buttweld connection on the other end. The flange allows the stub end to be bolted to a corresponding flange on the pipe or equipment being connected. The buttweld connection is used to weld the stub end to the pipe or tubing that needs to be connected.
Overall, a stainless steel long stub end is an essential component of many piping systems and is used to ensure reliable and efficient operation.

Long Stub End Types
Long 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 Long 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 Long 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. Long Stub End sometimes includes a machined rough face.
Type C
The Type C Long 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 Long Stub End on kind C is smooth, and it’s not machined.
