Classification of pipe fittings: according to purpose and connection
Pipe fitting is a general term for components in the piping system that function as connection,control,direction change,split,seal,and support.According to different processing methods,it is divided into four categories,namely butt welding pipe fitting(both welded and non-welded),socket welding pipe fitting,threaded pipe fitting and flanged pipe fitting.Pipe fittings contain 45°/90°/180° elbow,concentric/eccentric reducer,eqaul/reducing/lateral/barred tee,3D/5D/7D bend,cap,coupling,nipple,cross,stub end,union,outlet,swage nipple,etc.
There are many types of pipe fittings,which are classified according to their use,connection,materials,and processing methods.
By purpose:
- Pipe fittings for pipe joints are: flanges,unions,coupling,etc.
- Change the pipe fitting pipe direction: elbow,bend.
- Pipe fitting that changes the pipe diameter: eccentric reducer,reducing elbow,outlet and reinforcing pipe
- Increase the pipe fitting of the pipeline branch: tee,cross.
- pipe fitting for pipeline sealing: gasket,blind flange,plug,cap
By connection:
- Welded pipe fitting
- Threaded pipe fitting
- ferrule pipe fitting
- clamp pipe fitting
- socket pipe fitting
- bonded pipe fitting
- hot melt pipe fitting
- curved double pipe fitting
- rubber ring connected pipe fitting
By material:
- carbon steel: ASTM A105,A350 LF2,SS400,P235GH,P250GH,C22.8,Q235,20#,16Mn.
- stainless steel: ASTM A182 F304,F304L,F316,F316L,F321,F347,F310,F44,F51,etc.
- alloy steel: ASTM A694 F42,F46,F52,F56,F60,F65,F70,A182 F5,F9,F91,F12,F11,F22,etc.
