Seamless steel pipes are crafted from whole round steel and are devoid of any welds on the surface, earning them the name 'seamless steel pipes'. These pipes can be produced using various methods such as hot-rolling, cold-rolling, cold-drawing, extrusion, and top pipe manufacturing. Based on the cross-sectional shape, seamless steel pipes are categorized into round and special-shaped pipes, which include square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and finned designs. The diameters range from a maximum of 900mm to a minimum of 4mm. Depending on their application, they are divided into thick-walled and thin-walled seamless steel pipes. These pipes are predominantly used in petroleum geological drilling, petrochemical cracking, boilers, bearings, and high-precision structural steel applications for automobiles, tractors, and aviation.
