Stub Ends

Stub ends are used to connect pipes together along with a lap joint or backing flange. A stub end is welded to the end of each pipe that requires connecting with a lap join flange slip over the top of it before welding. Because the stub end has a serrated face it acts to seal both the pipes together. The lap joint flange is then bolted together with the mating lap joint flange to secure it all in place. This in turn means that the pipes can be opened easily to inspect or clean them, as they are not welded together, merely bolted together.

At Alexander Comley we press our own stub ends from seamless European pipes.
