Basic definition and usage classification of pipe fittings

Basic definition and use of pipe fittings:
Pipe fittings are parts that connect pipes into pipelines. According to the connection method, it can be divided into four categories: socket pipe fittings, threaded pipe fittings, flange pipe fittings and welded pipe fittings. It is mostly made of the same material as the pipe. There are elbows (elbows), flanges, three-way pipes, four-way pipes (cross heads) and reducers (small and small heads), etc. 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.

The use of pipe fittings is classified as follows:
1. The pipe fittings used to connect the pipes are: flanges, unions, pipe clamps, ferrules, hose clamps, etc. Tee
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 tapes, hemp, flange blind plates, pipe plugs, blind plates, heads
6. Pipe fittings used for pipeline fixing: snap ring, towing hook, lifting ring, bracket, bracket, pipe clamp, etc.

The pipe fittings are classified into the following categories according to the connection:
1. Welded pipe fittings
2. Threaded pipe fittings
3. Tube fittings
4. Clamp pipe fittings
5. Socket pipe fittings
6. Bonding pipe fittings
7. Hot melt pipe fittings
8. Rubber ring connection type pipe fittings

Pipe fittings are classified as follows according to materials:
1. Cast steel pipe fittings
2. Cast iron pipe fittings
3. Stainless steel pipe fittings
4. Plastic pipe fittings
5. pvc pipe fittings
6. Rubber pipe fittings
7. Graphite pipe fittings
8. Forged steel pipe fittings
9. PPR pipe fittings,
10. Alloy pipe fittings
11. PE pipe fittings
12. ABS pipe fittings

Development prospects of pipe fittings and building materials industry:
China is already the world's largest producer and consumer of building materials. The output of main building materials such as cement, plate glass, building and sanitary ceramics, stone and wall materials has ranked first in the world for many years. At the same time, the quality of building materials products continues to improve, the consumption of energy and raw materials is declining year by year, various new building materials are constantly emerging, and building materials products are continuously upgraded. Shanghai Huanqi Pipeline Co., Ltd. has a solid foundation. The main products are various valves, pipe fittings, low, medium and high pressure valves and pipe fittings, chemical valve pipe fittings and other products; various three-way, four-way, valve, reducer and other elbow pipe fittings; various plastic flanges; various poly Ethylene valve fittings, polypropylene pipes and other plastic valve fittings. At the same time, in the context of building an energy-saving society and the country's strengthening of independent innovation capabilities, the theme of energy conservation and technological innovation will be the hot spot for the development of the industry.
