Basic knowledge and function of pipe fittings
A fitting is a part that connects a pipe to a run. According to the different connection methods, it can be divided into four categories: socket fittings, threaded fittings, flange fittings and welded fittings. Do a lot with materials such as pipes. Elbow (elbow), flange, three-way pipe, four-way pipe (crosshead) and restrictor (reducer). Elbows are used to rotate pipes. The parts where the flanged pipe and the pipe are connected together are connected to the end of the pipe, and the three-way pipe is used where the three pipes gather. Four-way pipe where four pipes gather; this landscape is used where two pipes of different pipe diameters are connected.
What is the role of pipe fittings?
1. The pipe fittings used for pipeline interconnection include flange, live joint, pipeline hoop, sleeve and hoop.
2. Modify pipe fittings in pipe direction: elbows, elbows
3. Pipe fittings for changing pipe diameter: reducing diameter (reducing diameter), reducing elbow, branch pipe and strengthening pipe
4. Add pipe branch fittings: four-way
5. Pipe fittings for pipe sealing: gaskets, biomaterial tapes, Thelma, flange shutters, pipe blockage, shutters, magnetic heads
6. Pipe fixture: snap ring, traction, lifting ring, bracket, bracket, pipe clamp, etc.
What is the installation method of pipe fittings?
1. Pipe cutting:
According to the requirements of use, use a hacksaw to measure the length, manually use a saw or a small circular saw blade and other cutting tools to cut the required pipeline. After cutting, the two ends are vertically flat, and the burrs are removed with a knife, and the sharp angle is made, but not excessive. (John F. Kennedy, writer).
2. Connecting pipes and pipes:
Try to assemble the pipe fittings before bonding, determine the installation position and mark it, gently wipe the matching of pipes and pipe fittings with sandpaper or sandpaper, and then wipe it with cotton yarn. After volatilization, the bonding side of the pipe fittings shall also be evenly coated with the adhesive with a brush without leakage. After flattening, insert and transfer to the installation angle of the ideal combination. Beat with a mallet, the tube is all inserted into the bearing, and it can be fixed by itself after about 2 to 3 minutes. At this time do not force decomposition or turn. Otherwise, a leak may occur. After the assembly is completed, wipe the excess glue that has spilled in time to keep the pipeline clean. 3. Connect the spot tube:
First, clean the inner wall of the flared tube and the outer wall of the straight tube insertion part, rotate the rubber ring to the groove at the flared end (outside the inclined end of the rubber ring), connect the rubber ring, and apply lubricant to the straight tube insertion part. The insertion end of the straight tube can be aligned with the entrance of the extension opening. According to the construction site, the length of the straight tube from the flaring mark is marked on the insertion straight tube (the length must be shorter than the spot length).
Market analysis of pipe fittings
China is already the world's largest producer and consumer of building materials. The main building materials products such as cement, flat glass, building sanitary ceramics, stone, and wall materials have been 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 decreases year by year, various new building materials continue to appear, and building materials products continue to upgrade. Shanghai Huanqi Pipeline Co., Ltd. has a strong industry foundation. The main products are a variety of valves, pipe fittings, low and high pressure valves and pipe fittings, chemical valves and other products. All kinds of three-way, four-way, valve, reducer and other elbow fittings all kinds of plastic; with all kinds of polyethylene valve fittings, polypropylene pipe and other plastic valve fittings at the same time, in the context of energy-saving society and the country to strengthen the ability of independent innovation, energy saving and technological innovation theme will become the hot spot of industry development.
