What is Stainless Steel Stub End

Stub ends are also known as stainless steel lap joint stub ends. The primary purpose of a stub end, in conjunction with a stainless steel lap joint flange/backing flange, is to connect pipes in a piping system. The stainless steel stub ends are used in conjunction with the stainless steel lap joint flanges and backing flanges. While the lap joint flange is free to rotate around the stub end and slips directly over the pipe, the stub end is welded to the pipe into which it is to be installed.

Main Types Of Stainless Steel Stub End

Type A, B, and C stub ends are available in three different configurations. Stub ends of types A and B and C are produced in bespoke sizes and resemble forged fittings like elbows and tees.

Type A

The typical lap joint flange is utilized with type A Stainless Steel stub ends. The stub end's lap thickness is larger than or equal to the pipe wall's nominal thickness. The lap joint flange can also be received by type A's outer corner radius. It has a square inside the corner. The face of the lap is often machine-serrated.

Type B

Standard slip-on flanges are used as lap flanges and have a type B Stainless Steel stub end. These short ends' lap thicknesses are larger than or equal to the pipe wall's nominal thickness. Additionally, type B's outer corner radius is narrow enough to accommodate the slip-o flange, which can be utilized as a backup flange. It has a square inner corner. The face of a lap is often machine-serrated.

Type C

The type C Stainless Steel stub ends can be utilized with slip-on and regular lap joint flanges. The inside diameter of the lap has a rounded border where it has flared. The radius can be made almost square if necessary. 75% of the pipe wall makes up the lap thickness. Type C is extremely short and can fit any backup flange. The type C lap joint is smooth and not mechanical.

Ordinary Forms and Lengths

Type A and Type B manufacturing processes are typically used to create stub ends. They come in either the long (ANSI) or short pattern standard lengths (MSS).

Short lengths of schedule 5s and 10s stub ends are typically given, and larger lengths are available upon request. Stub ends for Schedule 40 are available in both short and long lengths.

Stainless Steel Stub End Compensation

Easy to prepare (needs neither parallel nor exactly flat cut faces).

b. It is possible to build a bond between two different metals, such as copper and aluminum.

c. Allows for varied thicknesses (thinner portions must be welded on top), allowing for the connection of thin materials like diaphragms and foils
