The pipe olet is mainly used for reinforcing pipe fittings of branch pipe connection, instead of using different diameter tee, reinforcing plate, reinforcing pipe section and other branch pipe connection types. It has the outstanding advantages of safety, reliability, cost reduction, simple construction, improvement of medium runner, series standardization, convenient design and selection, especially in high pressure, high temperature, large diameter, thick. The wall pipe is used more and more widely, which replaces the traditional branch pipe connection method.

Weldolet
This fitting's purpose is to make self-reinforced branch outlets on a larger (one size or more) run of pipe. The base of the common weld-o-let has a saddle shape to fit the run pipe. The outlet end of the weldolet has a beveled-end allowing for butt welding a pipe or fitting.

Sockolet
The Sockolet is also made much the same as the weldolet except that the outlet has a socket to match the socket welded piping fittings and pipe. The socket outlet sizes are normally limited to the smaller (2" and under) pipe sizes.

Threadolet
The Thredolet is made much the same as the Weld-O-Let except that the outlet is threaded to match the normal tapered pipe threads. The threaded outlet sizes are normally limited to the smaller (2" and under) pipe sizes.

Latrolet
A Latrolet is a weld on branch fitting that is attached to the run pipe at a 45° angle. The angle attachment is sometimes required on high pressure relief systems.

Elbolet
The Elbolet is made to be fitted on the back side of a long radius 90° elbow.

    There are various Pipe Fittings Manufacturing Process that used to manufactured Elbow, Tee, Reducers and other pipe fittings.

    Fittings are manufactured from Seamless Pipe and from Welded Pipe with filler material (ERW & EFW pipes cannot be used to manufactured fittings). large diameter fittings are manufactured from Plate.

    To manufactured wrought fitting various methods are used, these are the different type of Hot and cold forming process.

    These methods are:
    Hot forming or Extrusion Method
    Hydraulic Bulge method – Cold forming
    UO or Single weld seam Method
    Monaka or Double weld seam Method
    Deep Drawing Method for caps
    Flare Method for Stub ends
