Corrosion resistant steel pipe can be divided into two categories, inner lined anti-corrosion steel pipe and anti-corrosion steel pipe. Inner lined anti-corrosion mainly cement mortar lining anti-corrosion steel pipe application more, lower cost, using cement mortar coating on the pipeline to play a preservative effect. Outer wall anti-corrosion steel pipe applied more 3PE anti-corrosion steel pipe. Anti-corrosion technology with Huashida 3PE anti-corrosion coating production line is the process of protecting the outer wall or inner wall of the steel pipe to protect the pipeline itself. On the straight seam steel pipe, spiral pipe and other pipes can be processed. Huashida production line, the establishment of a sound quality assurance system, has passed ISO9001: 2000 certification, the implementation of the whole process of quality tracking control, reliable quality. Customers can assure.
