The stub ends are usually used with lap joint flanges, both of stub and lap joint flange can be purchased from EATHU. This flanged joint is an inexpensive flanged joint method suitable for low pressure and non-critical applications. Since the flange does not come into direct contact with the pipe, carbon steel short joints can be used to reduce the total weight and cost.
For more technical support please contact EATHU.

Question: I want to know the difference between Stub End Type A and Type B, which one is more suitable for me?
Eathu answer: Stub End has three different types – Type A, Type B, Type C, they are classified by the different “R” – the lap corner. But in actual working, “type A” is the common type as it is matching with lap joint flange specially.
Type A: To match standard lap joint flange, it is the default type if the client didn’t indicate the type specifically.
Type B: Stub End B type is mainly used for slip-on flanges and backing flanges, its lap angle is different from “type A”.
Type C: It can be used either with lap joint flange or slip-on flange. But it is not common type, most of eathu customers need “Type A” or “Type B” stub end.
