Stub Ends are mechanical joints that consist of two components. The Stub End which essentially a brief length of pipes, which has one end that’s flared outward and therefore, the other end prepared to be welded to the pipe of an equivalent Nominal Pipe Size (NPS), material, and of an identical wall thickness.
Stub ends are butt weld fittings which will be used alternatively to welding neck flanges to form flange connection. The utilization of stub ends has two advantages: it can reduce the entire cost of flange joints for piping systems in high material grades, it accelerates the installation process because the lap joint flange is rotated to facilitate the alignment of the bolt holes. Stub ends are available briefly and in long patterns (ASA and MSS stub ends), in sizes up to 80 inches.

Stub End Types
Type A :
- The Type A Stub End is used for the normal joint flange. The lap thickness on the Stub end is greater than or up to the thickness of the pipe wall. Additionally, the outer corner radius of type A will receive the lap joint flange. The within the corner is square. Lap sometimes includes a machined rough face.
Type B
- The Type B Stub End is used for normal slip-on flanges as lap flanges. The lap thickness on these short ends is greater than or up to the nominal thickness of the pipe wall. Also, the outer corner radius of B is small enough to receive the slip o flange which can be used as a backup flange. The inner corner is square. Lap sometimes includes a machined rough face.
Type C
- The Type C Stub End is going to be used for normal lap joint flange and placed on the flange. If necessary, the radius is going to be created close to a square. The lap joint Stub End thickness is 75th of the pipe wall. The type C is extremely short enough to accommodate any back up flange. The lap joint Stub End on kind C is smooth, and it’s not machined.

The Importance of proper packing for piping goods. it is not only protection of products or save cash but also proof of our professionalize. So for various goods, there are different protecting packing methods. For packing of Stub End with painting, We might use the bubble wrap to guard the painting. We might suggest client to use the anti-tarnish paper and bag to stop the rust. Each item is packed in poly pouches after multi stage inspections. These mini cartons are sealed and skilled Shrink Wrapping poly bag sealing machine to make sure safety from moisture. Such mini cartons are placed in bituminous hessian cloth 7 poly master carton. The contents of every master carton are shown on the carton. Each master carton is sealed with white printed heat salable strapping.
