Materials and Classifications of Metal Pipe Fittings

Materials and classifications of metal pipe fittings
Pipe fittings play the role of changing the direction, changing the elevation or changing the diameter, closing the pipe end and leading the branch pipe from the main pipe in the pipe system. In petrochemical plants, there are many types of pipelines. The pipeline system is complex and has various shapes. There are many types of pipe fittings used and made from different materials. They need to be selected according to the specific use.
 
Classifications of metal pipe fittings
There are many types of pipe fittings. Here we divide them based on connections, processing, and materials.
 
Classifications by uses
The pipe fittings used for the interconnection of pipes are flanges, unions, pipe clamps, ferrules, etc.
Pipe fittings that change the direction of the pipe are elbows and bends.
Pipe fittings that change the diameter of the pipe are reducers, reducing elbows, reinforcing pipe, etc.
Pipe fittings for adding pipeline branches are tees and crosses.
Pipe fittings for sealing the pipeline are gaskets, pipe plugs, blind plates, welded plugs, etc.
Pipe fittings for fixing the pipeline fixing are snap rings, lifting rings, brackets, pipe clips, etc.
 
Classifications by connections
Pipe fittings are classified into threaded pipe fittings, ferrule pipe fittings, clamp pipe fittings, socket pipe fittings, adhesive pipe fittings, hot-melt pipe fittings and apron-connected pipe fittings according to connections.
 
Classifications by processing methods
Pipe fittings are classified into push fittings, pressed pipe fittings, forged pipe fittings and casting pipe fittings based on processing methods.
 
Classifications by materials
Pipe fittings are classified into cast steel pipe fittings, cast iron pipe fittings, alloy pipe fittings, stainless steel pipe fittings, forged steel pipe fittings, non-ferrous metal pipe fittings, pipe fittings with special purposes, PPR pipe fittings, PE pipe fittings, ABS pipe fittings, plastic pipe fittings, PVC pipe fittings, rubber pipe fittings and graphite pipe fittings based on materials.
