Seamless steel pipes are crafted by perforating whole round steel, resulting in pipes devoid of surface welds, known as seamless steel pipes. Depending on the production method, seamless steel pipes can be categorized into hot-rolled, cold-rolled, cold-drawn, extruded seamless steel pipes, and top pipes. Based on cross-sectional shape, they are classified as either round or special-shaped pipes, which include square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and finned varieties. The diameter ranges from a minimum of 4mm to a maximum of 900mm. Seamless steel pipes are further classified into thick-walled and thin-walled varieties based on their applications. These pipes are predominantly utilized in petroleum geological drilling, petrochemical cracking, boiler manufacturing, bearing production, and as high-precision structural steel pipes for the automotive, tractor, and aviation industries.
