Pipe fitting (Pipe fitting) is a general term for the parts and components that play the role of connection, control, redirection, diversion, sealing, support, etc. in the pipeline system. Commonly used in water conservancy technology, irrigation and drainage, irrigation and other fields.
Steel pipe fittings are all pressure pipe fittings. According to the different processing technology, it is divided into four categories, namely butt welding pipe fittings (two kinds of welding seam and no welding seam), socket welding and threaded pipe fittings, and flange pipe fittings.
There are many types of pipe fittings, which are classified here according to use, connection, material, and processing methods.
一、Divided by purpose
1. The pipe fittings used to connect the pipes are: flanges, unions, pipe clamps, clamps, ferrules, hose clamps, etc.
2. Fittings that change the direction of the pipe: elbows, elbows
3. Fittings that change the diameter of the pipe: reducing diameter (reducing pipe), reducing elbow, branch pipe stand, reinforcing pipe
4. Increase the pipe fittings of the pipeline branch: three-way, four-way
5. Pipe fittings used for pipeline sealing: gaskets, raw material belts, hemp, flange blind plates, pipe plugs, blind plates, heads, welding plugs
6. Pipe fittings used for pipeline fixing: snap ring, towing hook, lifting ring, bracket, bracket, pipe clamp, etc.
二、Divided by connection
Welded pipe fittings, threaded pipe fittings, tube fittings, clamp pipe fittings, socket pipe fittings, bonded pipe fittings, hot melt pipe fittings, curved double melt pipe fittings, rubber ring connection pipe fittings
三、According to materials
Cast steel pipe fittings, cast iron pipe fittings, stainless steel pipe fittings, plastic pipe fittings, PVC pipe fittings, rubber pipe fittings, graphite pipe fittings, forged steel pipe fittings, PPR pipe fittings, alloy pipe fittings, PE pipe fittings, ABS pipe fittings
