The diameter and size specifications of spiral steel pipes should be flexible to cater to a wide range of user demands, leveraging their inherent advantages for widespread popularity and promotion. Steel pipes are generally produced using Q235 carbon镇静 steel as the raw material, and due to their high mechanical strength, they can withstand significant internal and external pressures. They can be made into water conveyance pipes with diameters exceeding 800 mm, making them one of the most commonly used large-diameter buried pipes in our country. The components of spiral steel pipes consist of an epoxy coal tar primer and topcoat, both primarily composed of epoxy resin and coal tar, with the addition of various anti-rust pigments, insulating fillers, toughening agents, leveling agents, diluents, and anti-settling agents.
