PVC pipe is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averaged 1.4 million tons. Some specific introductions to PVC pipes.
What is PVC Pipe used?
The PVC Pipe provided by the company.
PVC pipes (divided into PVC-U pipes, PVC-M pipes and PVC-O pipes) Rigid polyvinyl chloride pipes are made of polyvinyl chloride resin, stabilizers, lubricants, etc., and then extruded by hot pressing. The first plastic pipe to be developed and applied.
PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the seepage of PVC-U monomer and additives, it is only suitable for water supply systems whose conveying temperature does not exceed 45℃. Plastic pipes are used in drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, mud, gas, compressed air and vacuum systems.
PVC-O pipe, Chinese name biaxially oriented polyvinyl chloride, is the latest evolutionary form of PVC pipe. The pipe manufactured through a special orientation processing process will be stretched and diametrically produced by the extrusion method. Stretching to make the long-chain PVC molecules in the pipe arranged in a biaxial direction to obtain a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance.
The essence of PVC pipe is a kind of vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, which is used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for the largest proportion, at 60%, followed by the packaging industry, and there are several other small-scale applications.
PVC pipes are used for a long time and chloride ions are precipitated. They are not suitable for tap water pipes. They have poor impact resistance and are not suitable for gas pipes. However, PVC pipes are low in price, high in hardness, and are affected by temperature. Water supply pipes and drainage pipes are used for municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, and vegetation watering.
On the whole, there are many domestic small-caliber, low-value-added pipeline companies, and fewer large-caliber, high-tech companies. The distribution of processing capacity of PVC pipes is structurally unreasonable. The processing capacity of small and medium-sized enterprises is mainly concentrated in PVC drainage pipes. At the same time, a large number of non-standard pipes are still flooding the market, leading to disorderly and chaotic market competition.
