Stub ends are buttweld fittings that can be used (in combination with a lap joint flange) alternatively to welding neck flanges to make flanged connections.
Stainless steel stub end is a punching method for turning over the outer edge of the rough forgings or semi-finished product. the edge is turned into a vertical edge along a certain curve. When the edge of the stub end is a straight line, the converted deformation is converted into a curved, so it can also be said that a bending method is a special form of stub end.

Both stub end and cap manufacture standard can be ASME B16.9,ASME B16.28,MSS SP-43,MSS SP-75 JIS B2311,DIN2605/2615/2616/2617,GOST 17375/17376/17378/17379,ISO
Both stub end and cap wall thickness can be SCH10/10S, SCH20/the 20S, STD, SCH40/40S, XS, SCH80, XXS ETC.(for ANSI), SGP(for JIS)
Size: 1/2"-48"(DN15-DN1200), or even bigger
Finishing: Polished, Pickled.
Connection type: Butt Welding
One end of stub end is connected with a flange, and one end is butt welded with pipe, directly in contact with the medium.
Stub ends are buttweld fittings that can be used (in combination with a lap joint flange) alternatively to welding neck flanges to make flanged connections.
Stub ends are widely used in the petroleum, chemical, power, gas, metallurgy, shipbuilding, and construction industries. They are made from high-quality raw materials, and are available in a variety of sizes and designs.
