PVC is the world's second-largest general-purpose synthetic resin material. It has excellent flame resistance, abrasion resistance, chemical resistance, comprehensive mechanical properties, product transparency, electrical insulation, and easy processing.
At present, PVC has become one of the most widely used plastics in the fields of application. It is widely used in industry, construction, agriculture, daily life, packaging, electricity, public utilities and other fields. It is compatible with polyethylene (PE) and polypropylene (PP). , Polystyrene (PS) and ABS are collectively referred to as the five general-purpose resins.
In recent years, global PVC production capacity has continued to grow. According to IHS data, in 2018, the global PVC production capacity was 55.4 million tons, and in 2019, the global PVC production capacity was about 57.17 million tons.

PVC pipe: also known as polyvinyl chloride pipe, is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. It is the first plastic pipe to be developed and applied. PVC pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the seepage of PVC monomer and additives, it is only suitable for water supply systems whose conveying temperature does not exceed 45℃. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, mud, gas, compressed air and vacuum systems.
It 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.

PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains plasticizers (this is also the difference between soft PVC and hard PVC), its physical properties are poor (such as water pipes that need to withstand certain water pressure, soft PVC Not suitable for use), so its scope of use is limited. Rigid PVC does not contain plasticizers, so it is easy to shape and has good physical properties, so it has great development and application value. In the production process of PVC materials, several additives, such as stabilizers, plasticizers, etc. are bound to be added. If all environmental additives are used, then PVC pipes are also non-toxic, tasteless and environmentally friendly products.

Advantages of PVC pipes and PVC pipe fittings:
1. It has good tensile and compressive strength: but its flexibility is not as good as other plastic pipes.

2. Low fluid resistance: The wall of PVC-U pipe is very smooth, and the resistance to fluid is very small. Its roughness coefficient is only 0.009. Its water delivery capacity can be 20% higher than that of cast iron pipes of the same diameter and 40% higher than that of concrete pipes. %.

3. Excellent corrosion resistance and chemical resistance: PVC-U pipes have excellent acid resistance, alkali resistance, and corrosion resistance, and are not affected by damp water and soil pH. No anti-corrosion treatment is required when laying pipes.

4. It has good water tightness: the installation of PVC-U pipes, regardless of whether it is connected by bonding or rubber ring, has good water tightness.

5. Anti-bite: PVC-U tube is not a source of nutrition, so it will not be corroded by rodents. According to a test conducted by the National Sanitation Foundation in Michigan, rats will not bite PVC-U pipes.
