The inspection of the damage resistance of PVC pipes is mainly through the drop weight impact test. During the test, the pipe can be damaged once in ten tests, but when the drop weight impact test of the PVC pipe on the market is carried out, there are many pipes that do not meet the standard. This shows that these PVC pipes do not have qualified damage resistance in the face of collisions in the process of transportation and installation, which also brings safety hazards to actual production and life to some extent. At present, the production technology of PVC pipes is gradually mature. For the production of any kind of PVC pipes, the general process is formula, mixing, cold mixing, sieving, foundation, cooling and sizing, cutting, flaring, testing. , packaging, etc. Generally speaking, as long as these processes are scientifically and standardized management, reasonable arrangement of production can ensure the quality of PVC pipes. However, some manufacturers do not supervise and manage the quality of pipes in place, which will affect the quality of pipes.
