Steel tubular structure is an architectural term announced in 2014. Structural seamless steel pipes are seamless steel pipes used for general structures and mechanical structures. According to the material, it is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; this kind of structural steel pipe has the largest output and is widely used. etc.) and the manufacture of profiles and welded steel pipes. Mainly used for building structures such as workshops, bridges, ships, etc. and general pipelines for conveying fluids. This type of steel is generally used directly without heat treatment. Stainless steel for industrial corrosion-resistant pipes and structures and parts made from hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless tubes. Using steel pipes as ferrules can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc. Low-alloy high-strength structural steel pipe uses carbon instead of structural steel. It has the advantages of high strength, good comprehensive performance, long service life, wide application range and relatively economical.
