Anti corrosion steel pipe: cement mortar lining pipeline internal corrosion is the use of a variety of molding process, mix the cement mortar, the cleaned pipe wall thickness according to the design requirements, one or more times with lining, after a certain time of curing, forming a tightly combined with the inner wall of the tube high strength round shell lining layer. Using the cement mortar special alkaline, so that the inner surface of the pipe to form a passivation film and protection technology at home and abroad, has been widely used in the pipeline anticorrosion, think generally, it is a pollution-free, non-toxic, easy construction, low cost, promising pipeline anti corrosion technology.

Thermal insulation pipe product characteristics
