China Big Factory Good Price 4in 8 Bar Color Customized Pvc Socket Connection Upvc Pipe With The Salesman Consulting
UPVC has high melt viscosity and poor fluidity. Even if the injection pressure and melt temperature are increased, the fluidity does not change much. In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range that can be molded is very narrow, making it a difficult material to mold.

Features: Usually the diameter is 40-100mm, the inner wall is smooth and the resistance is small, no scaling, non-toxic, non-polluting, corrosion-resistant. The use temperature is not more than 40 degrees, so it is a cold water pipe. Good anti-aging performance, flame retardant, can be installed with flexible connection of rubber ring.
Selection of U PVC pipe
1) Select qualified pipes. The UPVC water supply pipes used in the construction must meet the national standards for rigid PVC water supply pipes, and must have product qualification certificates and quality inspection reports.
2) Consider pipeline burial conditions. According to more than ten years of construction experience, the covering thickness of UPVC pipes above de63 should be at least 0.7m, and the covering thickness of UPVC pipes below de63 can be appropriately reduced, but it should not be less than 0.5m. below the freezing line. The pipe should not be in contact with hard substances. The bottom of the UPVC pipe, within 30cm above it, and the chest cavity should be filled with loam or sand, especially the chest cavity should be backfilled tightly, so that the pipe body will not be damaged when the pipe is subjected to external pressure. Therefore, when choosing U PVC pipes, the buried pipe conditions and soil conditions should be considered.
3) The problem of thermal expansion and contraction. The linear expansion coefficient of U PVC pipe is large, which is 60～80*10- 61 °C, while the linear expansion coefficient of carbon steel pipe is 11. 4*101 °C, and the linear expansion coefficient of cast iron pipe is 10. 5*101 ° C. Therefore, the effect of temperature changes on U PVC pipes must be considered to prevent the damage of temperature stress to the pipes. To solve the problem of thermal expansion and contraction, it is only necessary to use part or all of the rubber ring interface for pipeline connection during construction.
4) According to the operating pressure of the pipeline, select the U PVC pipe of the corresponding pressure level. U PVC pipes generally have 5 pressure levels, namely 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, 1.6MPa. The general pipeline pressure below de63 is high, and the pipeline pressure greater than 63 generally has three levels of 0.6MPa, 8MPa, and 0MPa.
