A Stub End fitting is a short length of pipe with one flared end and the other end needing to be welded to the pipe of the same size. A combination of stub ends and backing flanges is an alternate way of joining pipes compared to the use of standard flanges. The use of stub ends reduces the weight of the flanged joints. The stub ends allow quick disconnection of the particular section involved. Stub ends are installed in pairs and mated together with two lap joint flanges.


These can also be used in high-pressure pipelines. The stub ends do not get in contact with the fluid conveyed by the pipeline. Stub ends allow sections of the line to be opened without the need to re-weld. Aspirinox Alloys Inc is a quality buttweld Stub End Supplier.
