Spiral steel pipes are generally divided into two categories during use: overhead pipes and buried pipes. As the name implies, overhead pipes are used on the ground. They are generally set up with concrete buttresses and pipe brackets, and some are used on pipe galleries. The buried pipes are buried underground according to the design, and their depth is also determined according to the design. The advantage of the pipe is that it is convenient and beautiful, because it is buried in the ground, so the space on the ground can be used for other purposes.

But whether it is an overhead pipe or a buried pipe, there is a common disadvantage, that is, because the spiral steel pipe is a steel pipe and carbon steel material is used, oxidation and corrosion will inevitably occur, so the anti-corrosion process of the spiral steel pipe is It came into being, in fact, the anti-corrosion technology of spiral steel pipe has been very mature. Now let's introduce what is anti-corrosion spiral steel pipe.

Anti-corrosion spiral steel pipe is divided into internal anti-corrosion and external anti-corrosion, that is, the inner and outer walls of the spiral steel pipe are processed with anti-corrosion. There are many anti-corrosion forms of spiral steel pipes, including plastic-coated anti-corrosion, epoxy coal tar tar anti-corrosion, epoxy resin anti-corrosion, three-oil two-cloth, five-oil three-cloth, six-oil four-cloth, epoxy cloud iron, etc.
