Branch outlet pipe is the support of large diameter pipe to small diameter pipe.Branch outlet is a reinforcing type pipe fitting mainly used for intuitive connection. It is a connection form of branch pipe, such as strengthening pipe segment, instead of using reducing three-way reinforcing plate.Branch connections have full specifications, types, holes, and working pressure levels.
Branch outlet pipe has the advantages of safety and reliability, cost reduction, simple construction, improvement of medium channel, serialization and standardization, convenient design and selection, etc., especially in the high pressure, high temperature, large diameter, thick wall pipeline is increasingly widely used, replacing the traditional branch pipe connection method.
Common branch outlet pipe classification: Weldolet, Sockolet, Threadolet, Latrolet, Nipolet.
Weldolet is most common and economical of all branch connections, it is welded to the main run pipe (larger size) and connceted to the branch pipe (small size). The shape of the Weldolet ensures little stress concentration on the branched pipe, providing an integral reinforcement.
It is molded by round steel or steel ingot and then machined by lathe. One end of the socketolet is flat, inserted into the branch pipe, and then fillet welded together. It has higher tensile strength, firmness, corrosion resistance, higher durability, excellent weld ability and longer service life.
Threadolet have a female thread connection in its bore section that screwed to the fittings, it is manufactured as standard MSS MS-97. It typically is in the size range of 1/2″ to 2” and is welded over a hole either drilled or burned in the pipe.
Latrolet fitting is a kind of special olets that used in the piping system. It is available in connection of butt weld, threaded and socket weld. The ends of a Latrolet are bevelled to facilitate the welding process, and for this reason Latrolet belong to the family of butt weld fittings.
Nipolet is not common type of branch connection that also called nipple outlet, the connection end can be plain end and screwed. It is available with varying ends as Plain or bevelled ends, both of them are used for weld connections while the ends for screw connections have an external thread.
