The cement pipe is a kind of prefabricated pipe made of cement and steel bar by using the principle of centrifugal force of electric pole. When the welded joint of the reinforcement mesh is not firm, the reinforcement will run and leak, which will make the pipe body partially without reinforcement;
After forming, it is difficult to center the reinforcement mesh. The reinforcement mesh is eccentric, that is, the protective layer of the reinforcement mesh is uneven; This process requires a large number of molds to ensure the output. The size of each mold is biased, and large deformation will occur when the split mold is disassembled and used for a long time. Therefore, the roundness of the pipe, the perpendicularity of the pipe orifice, the pipe diameter size and the pipe length size of the pipe are greatly deviated, affecting the installation quality of the project. The leakage will lead to the subsidence of the road surface and cause pollution to the soil and groundwater on both sides of the pipeline.
First of all, we need to build a steam curing pool. The general steam curing pool needs 2.5 meters wide, 4 meters long, and 3 meters deep. It can also be sized according to its own production capacity and the size of the mold. It also needs a boiler to deliver steam to the steam curing pool. The steam curing pool has a good tightness, and it can be used after the steam curing pool is completed. After the cement pipe is completed, it can be hoisted into the steam curing pool for steam curing. Generally, the cement pipe will be solidified after 2.5 to 3.5 hours of steam curing, Generally, the higher the temperature, the shorter the steam curing time. The steam curing time is inversely proportional to the steam temperature. The higher the temperature, the better.
