PLASTIC PIPES ATTRACT ATTENTION IN FIVE AREAS

Plastic pipes attract attention in five areas

Plastic pipes have more incomparable advantages than traditional cast iron pipes, steel pipes, and cement pipes, such as smooth inner walls, low resistance, and good sealing, which can guarantee no leakage to a large extent; corrosion resistance, long service life; fewer plastic pipe joints , Easy connection and quick construction. Although the unit price of plastic pipes is slightly higher than that of cement pipes, the total project cost is 30% lower than cement pipes. Now the advantages of plastic pipes are being recognized by more and more users. According to the data of the Ministry of Construction, the domestic plastic pipeline market value will reach 800 billion yuan in the next three years, of which five major application areas attract attention: drainage pipe network, water supply pipe network, gas pipe network, optical cable sheath pipe network, buried power pipe network.

The development of special materials for plastic pipes provides a guarantee for the development of the plastic pipe industry

The most advanced plastic pipe enterprises in the world all use special pipe materials to produce pipes and fittings. Because this kind of special material for pipes has been formally measured by authoritative testing institutions for long-term performance, the production of this special material for pipes can ensure that it fully meets the standard requirements and ensures the service life of the products.

China's plastic pipe industry has a relatively late understanding of the need to use special pipe materials. This is due to many reasons; first, because of the backwardness of China's plastic pipe standards in the past, there is no clear requirement for materials; Enterprises often have to 'preparation' of materials suitable for the production of pipes and fittings using the raw materials they may buy; thirdly, because most of our country used to produce PVC pipes in the past, traditionally, the pipe enterprises made their own formulas and mixed them. (To date, there is no special material for PVC pipes that has been subjected to formal testing to determine long-term performance).

At the same time, China's plastic raw material companies used to pay attention to the production of special pipe materials late. There are many reasons for this: First, because China's plastic pipe industry was relatively backward in the past, no clear requirements for special pipe materials were proposed; Second, China's plastic raw materials have been in short supply for a long time, and raw material production enterprises have no interest from economic interests to produce pipes with limited consumption at that time. Special materials.

The gratifying progress in recent years is that this situation has changed. More and more pipe companies realize that qualified pipe special materials must be used to ensure quality. A number of polyolefin pipe and pipe production enterprises with higher technical content have insisted on using qualified pipe special materials, even if they have to import relatively high prices The special pipe material is also not shaken. At the same time, some polyolefin raw material production enterprises with higher technological content have been actively developing and producing regular pipe special materials that meet the requirements of international standards. At present, there are already a batch of domestically produced special materials for pipes, some of which have passed the formal long-term performance test. In recent years, Shanghai Petrochemical, Qilu Petrochemical, Yangzi Petrochemical, etc. have also developed various grades of special pipe materials. The development of special plastic pipe materials in China has provided a guarantee for the development of the plastic pipe industry.
