The pipe fitting is a component that connects the pipe into a pipe. According to the coupling method, it can be divided into four types: socket pipe fitting, threaded pipe fitting, flanged pipe fitting and welded pipe fitting. The elbow is used for the pipe to turn; the flange is used to make the pipe The parts connected to the pipe are connected to the pipe end, the tee pipe is used for the place where the three pipes are collected, the four-way pipe(cross pipe) is used for the place where the four pipes are collected, and the reducer pipe is used for the connection of the two pipes of different pipe diameters.

Elbow

Seamless Elbow Manufacturing Process (Heat Bending & Cold Bending) One of the most common methods for manufacturing elbows is using hot mandrel bending from straight steel pipes. After heating the steel pipe at a elevated temperature, the pipe is pushed, expanded, bended by the inner tools of mandrel step by step. Applying hot mandrel

Flange

Pipe Flanges, Flanges Fittings Slip-on pipe flanges  Slip-on pipe flanges actually slip over the pipe.  These pipe flanges are typically machined with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe.  This allows the flange to slideover the pipe but to still have a somewhat snug fit.  Slip-on pipe flanges are secured to the pip

Tee

Pipe Tee, Tee Fittings A tee is also called triplet,three way and “T” pieces and it can be used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but ‘reducing’ tees are available as well. 

Reducer

A steel pipe reducer is a component used in the pipelines to reduce its size from large to small bore in accordance to the inner diameter. The length of the reduction here is equal to an average of the smaller and larger pipe diameters. Here, the reducer can be used as a diffuser or a nozzle.
