Cement pipes, also known as cement pressure pipes and reinforced concrete pipes, can be used as sewage pipes in urban construction foundations, and can discharge sewage, flood water, and water pipes and farm machinery wells used in some special factories and mines. Generally divided into: flat mouth reinforced concrete cement pipe , flexible grooved reinforced concrete cement pipe , socket socket reinforced concrete cement pipe , F-shaped steel socket cement pipe , flat mouth ring joint cement pipe , tongue and groove cement pipe and so on.
After the cement pipe is manufactured on the cement pipe making machine, the cement pipe and the cement pipe mold are hoisted into the steam curing tank for steam maintenance, which takes about 3-4 hours. The steam curing process requires 3 stages: the temperature in the steam curing tank is low (30 -40 degrees) to high temperature (100 degrees) requires about 1 hour, the second stage needs to adhere to the high temperature of about 1 hour (about 100 degrees), and the third stage from high temperature to low temperature also needs about 1 hour. After 3 hours, the cement tube was steamed and the concrete was set.
