Important Features Of Stainless Steel Stub End
Additionally known as stainless steel lap joint stub ends, stub ends In conjunction with a stainless steel lap joint flange/backing flange, the stub end’s primary purpose is to link pipes together in a piping system. The stainless steel lap joint flanges and backing flanges are used in conjunction with the Stainless Steel Stub end While the lap joint flange slips directly over the pipe and are free to revolve around the stub end, the stub end is welded to the pipe into which it is to be installed.
Main Types Of SS 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.
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).

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