After the cement pipes are cast, they should be cured to ensure the hardness, density and structure of the cement pipes. Generally, after the concrete has initially set, the mold can be removed from the cast cement pipes, and then the cement pipes can be cured. During the curing process, the cement pipes should be kept moist, and measures such as spraying water on the surface of the cement pipes and covering them with insulation materials should be taken to ensure that the cement pipes have sufficient strength and wear resistance after curing.
