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, which is crucial for the widespread adoption and promotion of spiral steel pipes. Steel pipes are typically manufactured using Q235 carbon镇静 steel, which offers high mechanical strength, enabling them to withstand significant internal and external pressures. This allows for the production of 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 an epoxy coal tar enamel primer and topcoat, both primarily composed of epoxy resin and coal tar as the film-forming materials, supplemented with various anti-rust pigments, insulating fillers, tougheners, leveling agents, diluents, and anti-settling agents.
