How to maintain cement pipes

When it comes to cement pipes, everyone is no stranger. Cement pipes are a kind of prefabricated pipes made of cement and steel bars and using the principle of the centrifugal force of electric poles. Cement pipes are also known as cement pressure pipes and reinforced concrete pipes. They can be used as sewage pipes in urban construction foundations, which can discharge sewage, flood control and drainage, as well as water pipes and farm machinery wells used in some special factories and mines. It is widely used because it is one of the equipment that we can use to better life. We must know that in order to make better use of cement pipes, in other words, it extends the life of cement pipes. This requires maintenance of concrete pipes. as follows:

First of all, natural maintenance is a method for maintaining cement pipes. After the cement pipes are finished, the cement pipes and molds are placed in the open air for natural maintenance. Generally, after the cement pipes are finished, it is necessary to perform open-air maintenance at the time of the day before the next day. After the mold is opened, natural maintenance is required for 4-6 days, and a special person sprays water on the cement pipe three times a day, usually once in the morning, once at noon, and once in the afternoon. The intention of the water spray is to maintain the humidity of the cement pipe. The concrete can be gradually set by itself, and the number of water sprays can be increased and decreased according to the climatic conditions and the humidity of the climate. However, there are more molds required for natural maintenance.

Secondly, the steam curing method can be performed on the cement pipe. Of course, a steam curing pond must be built. The general steam curing pond needs 2.5 meters wide, 4 meters long, and 3 meters deep. It can also be determined according to the production capacity and the size of the mold Scale, the boiler is also required to transport steam to the steaming pond, the sealing of the steaming pond is better, and the steaming pond can be used after it is completed. After the cement pipe is completed, it can be hoisted into the steaming pond for steaming. Generally, steaming requires 2.5--3.5 hours. The cement pipe will condense in the future. Generally, the higher the temperature, the shorter the steaming time and the steaming time Inversely proportional to the temperature of the steam, the higher the temperature the better.
