Stub End

Stub End is a short length of pipe with one flared end and one square-cut end, which is welded to a pipe of the same NPS, material grade and schedule. Stub ends are fittings used in place of welded flanges where rotating back up flanges are desired. They are mainly used with standard Lap Joint Flanges

Stub ends allow to minimize the weight of high-grade material in stainless, duplex, and nickel alloy piping, saving costs.

The stub ends are available in three types –

Type A, Type B and Type 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 stub end is used for standard lap joint flange. The lap thickness on the stub end is greater than or equal to the nominal thickness of pipe wall.

Type B – The type B stub end is used for standard Slip On Flanges as lap flanges. The lap thickness on these short ends is greater than or equal to the nominal thickness of pipe wall.

Type C- The type C stub end can be used for standard lap joint flange and slip on flange. It is flared leaving a rounded edge at the inside diameter of the lap. If necessary, the radius can be made closed to a square.

They are also available in two patterns – Short pattern and Long pattern.

Stub ends exhibit many benefits such as

Stub Ends also match both pipe material and wall schedule to maintain both inside and outside diameters of your piping process. This style is typically used in engineered piping systems with critical wall thickness requirements. The combination of a Stub End and a backing flange is generally used as an alternative to a standard flange. Stub ends are available in most grades of material.
