Pipe Fittings SScm415 Chromoly Stub End


Pipe Fittings SScm415 Chromoly Stub End Stainless Steel Stub End Pipe Fittings are buttweld fittings that can be used in combination with a lap joint flange. Alternatively the ASME B 16.9 Stub End can be used with welding neck flanges to make flanged connections. The use of Lap Joint Stub End has two advantages. One , the ANSI B 16.9 Stub End can reduce the total cost of flanged joints when used in a piping system in high material grades. This is because the lap joint flange does not need to be of the same material of the pipe while the Stub Ends B16.9 but could be a lower grade. And two , the Long Stub End speeds up the installation process. Since a lap joint flange can be rotated to smoothen the alignment of the bolt holes. Stub End Din 2642 fittings are available in short and long pattern i.e. - ASA and MSS ASME B16.9 Stub End .

ANSI / ASME B16.9 Stub End

Stub End Buttweld Fittings are available in three different types. These ASME B16.9 Stub End can be labelled as - Stub End Type A , Mss Type B Stub End and Type C : The first type is the Stub End Sch 10 Type A fitting. This type A Stub Ends Specification has been manufactured and machined to match standard lap joint backing flange. This is because both the lap joint backing flange as well as the type A Stub End Jis 10k have to be used in combination. The mating surfaces of the Stub End Type A have an identical profile, which permits the smooth loading of the flare face Type B Stub Ends Stainless Steel are to be used with standard slip-on flanges. Stub End Carbon Steel in Type C could be used either way – i.e. - with lap joint or with slip-on flanges. These type C EN 1092-1 Stub End are manufactured from pipes. Ss Stub End Dimensions could be ordered with different finished ends such as Bevelled Ends, Grooved Ends, Squared Ends , Flanged Ends as well as Threaded Ends which are meant for Male fittings Only.

What is ASME B16.9 Stub End?

The Stub End EN 1092-1 Type 35, is essentially a piece of pipe, with one end flared outwards whereas the other end has to be prepared to be welded to a pipe which will be the same bore size or NPS i.e - nominal pipe size, material as well as wall thickness. The most extensively used fabrication tool for Type B Stub End Dimensions is the flaring machine. This machine is able to flare the end of the pipe of the Stub End EN 1092-1 Type 36 and then cuts it to length.
