With the improvement of people's living standard, environmental awareness and attention to health, a green revolution of the industry has been set off in the field of water supply. The traditional water supply pipe -- galvanized steel pipe has been restricted and eliminated. Instead, it is an environmentally friendly, robust and modern water supply pipe.
In recent years, plastic pipes have developed really quickly in our country. With the acceleration of urbanization, in the face of the great pressure of population, resources and environment, in order to ensure the sustainable development of the national economy, a variety of current environmental protection pipes such as rain spring up, of which PE steel wire mesh skeleton composite pipe is the representative, the output is increasing, demand exceeds supply, has become a hot investment.
In particular, as a representative of the green pipeline in the chemical industry and construction industry, the steel wire frame PE pipe with its tiny density, excellent corrosion resistance, long service life and excellent health, environmental friendliness and other advantages occupies a higher and more influential position in the plastic pipeline market.
Now according to the national policy, all walks of life are advocating the concept of environmental protection, pipes are the same, pay attention to efficient environmental protection, in the energy saving and consumption reduction to make a contribution, so why is the steel wire mesh skeleton composite pipe an environmental protection pipe? The following and HDPE pipe fitting suppliers together understand.
Characteristics of composite pipe
Steel wire mesh skeleton plastic composite pipe is a mesh skeleton formed by high-strength steel wire left and right spiral winding as the reinforcement body, with high density polyethylene as the matrix, and high performance bonded resin layer is used to wire mesh skeleton and inside and outside high-density polyethylene tightly connected together. Not only has anticorrosion, no scaling, smooth, heat preservation, no wax, wear resistance, light weight and other characteristics of plastic pipe, but also its peculiar structure has created the following characteristics:
(1) Extreme bearing capacity, not easy to creep
Plastic will creep under normal temperature and stress, and brittle fractures will occur under long lasting stress. Therefore, the allowable stress and bearing capacity of pure plastic pipes are extremely low. The mechanical strength of steel is about 10 times that of thermoplastic, and it is extremely stable and does not creep in the temperature range of plastic. When the steel wire mesh frame is combined with plastic, the steel wire mesh frame can effectively restrain the creep of plastic and considerably improve the lasting strength of plastic itself. Therefore, the allowable stress of steel wire mesh frame plastic composite pipe is twice as strong as that of plastic pipe.
(2) rigid and flexible, easy installation and excellent economy
The rigidity, impact resistance and dimensional stability of plastic composite pipe with steel wire mesh skeleton are better than any other pure plastic pipe due to the strengthening effect of steel wire mesh skeleton. Plus, the wire mesh skeleton itself has a flexible structure, so that the composite pipe also has a certain flexibility in the axial direction. Therefore, the pipe has the advantages of rigid and flexible combination.
In unloading, transportation, installation adaptability and reliability of operation are excellent performance.
(3) There is no rapid cracking
The existence of steel mesh makes the deformation and stress of plastic not reach the critical point of rapid cracking of pure plastic pipe. Therefore, theoretically speaking, steel wire mesh skeleton plastic composite pipe does not have rapid cracking.
(4) Double-sided corrosion resistance
The steel wire mesh skeleton is composite in the plastic by special hot melt adhesive, the inner and outer surfaces of the pipe have the same anti-corrosion performance, wear resistance, smooth inner wall, tiny transmission resistance, no scaling, no wax, energy saving effect is obvious, it is more economical and convenient for buried transportation and corrosive environmental conditions.
(5) The composite of steel and plastic materials is uniform and reliable.
At present, the steel-plastic composite pipe on the market because the composite surface between steel and plastic is a continuous regular interface, long-term use under the action of alternating stress is easy to delamination, resulting in leakage at the joint. In contrast, the steel wire mesh skeleton plastic composite pipe is a mesh structure through a special hot melt adhesive to make plastic and steel wire mesh closely combined and integrated. The binding force between the two materials is large and uniform, and the stress concentration is tiny.
(6) Excellent self-tracer
Because of the existence of steel wire mesh skeleton, the plastic composite pipe buried underground can be located by the usual magnetic detection method, to avoid the damage caused by different excavation operations.
(7) Low thermal conductivity, winter use of outer wall does not need heat preservation, summer use is not dew
(8) Green environmental protection - health, non-toxic, pollution-free environment, no secondary pollution
(9) Convenient installation, various interfaces
Special electric fusion joint, variety, installation is extremely quick and reliable steel wire mesh skeleton composite plastic pipe above characteristics, so that it is more and more widely used in the water supply pipeline, especially the buried water supply pipeline.
(10) Tiny thermal expansion coefficient
The thermal expansivity of steel wire mesh frame plastic composite pipe is considerably improved under the constraint of steel mesh frame, which is lower than that of any common plastic pipe.
Steel wire mesh skeleton composite pipe is a modern type of pipe. Its outstanding performance advantages can not be ignored, its wide range of uses, not only for water supply, can also be used for industrial acid and alkali water, and in the medical aspect also has a very significant use value. Its structure is simple and reasonable, easy to operate, and the pipeline problems are easy to maintain. According to the current situation, whether in the future on the equipment or application, environmental protection will become the inevitable trend of development.
