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 adoption and promotion. Steel pipes are generally manufactured from Q235 carbon镇静 steel, offering high mechanical strength to 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 pipelines in our country. The components of spiral steel pipes consist of epoxy coal tar enamel primer and topcoat, both primarily composed of epoxy resin and coal tar as the film-forming materials, with the addition of various rust-proof pigments, insulating fillers, toughening agents, leveling agents, diluents, and anti-settling agents.
