Pipe fittings are parts that connect pipes into pipelines. Pipe fittings are used in disciplines such as water conservancy technology, irrigation and drainage. According to the connection method, it can be divided into four categories: socket type pipe fittings, threaded pipe fittings, flange pipe fittings and Welded Pipe Fittings. They are mostly made of the same material as the pipe. In addition to the classification according to the connection method, there are other methods of classification. Today, let's take a look at the types of pipe fittings?
Pipe fittings include elbows (elbows), flanges, three-way pipes, four-way pipes (cross heads) and reducers (small and small heads). The elbow is used where the pipe turns; the flange is used to connect the pipe and the pipe to each other, connected to the pipe end, the three-way pipe is used for the place where the three pipes meet; the four-way pipe is used for the place where the four pipes meet; Diameter pipes are used where two pipes of different diameters are connected. According to manufacturing standards, pipe fittings can be divided into national standards, electrical standards, ship standards, chemical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.
Pipe fittings are a general term for the parts and components that play the role of connection, control, change of direction, diversion, sealing, and support in the pipeline system.
Malleable Iron Pipe Fittings
There are many types of pipe fittings, which are classified according to use, connection, material, and processing methods.
1. The pipe fittings used to connect the pipes are: flanges, unions, pipe clamps, clamps, clamps, hose clamps, etc.
2. Fittings that change the direction of the pipe: elbows, elbows.
3. Fittings for changing the pipe diameter: reducing diameter (reducing pipe), reducing elbow, branch pipe stand, reinforcing pipe.
4. Increase the pipe fittings of the pipeline branch: three-way and four-way.
5. Pipe fittings used for pipeline sealing: gaskets, raw material tapes, 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.
According to the connection points, they are divided into nine categories, namely: 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 type Pipe fittings.
According to the material, it is divided into twelve categories, namely: 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.
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 (there are two kinds of welding seam and no welding seam), socket welding and threaded pipe fittings, and flange pipe fittings.
