As a new type of pipeline, CPVC pipeline has excellent corrosion resistance. In recent years, it is widely used in steel, metallurgy, petroleum, chemical industry, chemical fertilizer, dye, pharmaceutical, electric power, environmental protection and sewage treatment industries. It is an ideal substitute for metal anticorrosive materials.

Due to the increase of chlorine content in the material, the irregularity of CPVC molecules in the structure increases (the crystallinity decreases, the polarity of the molecular chain increases), so that its thermal deformation temperature rises.

The use temperature of CPVC products can reach up to 93-100℃, which is 30-40℃ higher than PVC. At the same time, it improves the chemical resistance and corrosion resistance of PVC, which can resist the chemical corrosion of strong acid, strong base, salt, fatty acid salt, oxidizing agent and halogen.

Product advantages：
1. The pipe has excellent surface hardness and tensile strength.
2. It has good aging resistance and its normal service life can reach more than 50 years.
3. The pipeline has excellent corrosion resistance to inorganic acids, alkalis, and salts, and is suitable for industrial sewage discharge and transportation.
4. The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to be blocked, and the maintenance workload is small.
5. The material has a high oxygen index and is self-extinguishing.
6. The linear expansion coefficient of the pipeline is small, 0.07mm/℃, and the deformation affected by temperature is small. The thermal conductivity and elastic modulus are small, and compared with cast iron drainage pipes, they have excellent freezing resistance.
7. Bonding can be used to connect pipes and pipe fittings. The construction method is simple, the operation is convenient, and the installation efficiency is high.
8. Good water tightness: PVC-U pipes have good water tightness regardless of whether they are connected by bonding or rubber rings.
