Seamless steel pipes are crafted from whole round steel and feature no welds on their surface, thus called seamless steel pipes. Depending on the production method, these pipes can be categorized into hot-rolled, cold-rolled, cold-drawn, extruded, and top pipes. Based on the cross-sectional shape, they are either round or special-shaped, including square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and finned pipes. With a maximum diameter of 900mm and a minimum diameter of 4mm, seamless steel pipes serve various purposes. They are classified into thick-walled and thin-walled for different applications and are extensively used in petroleum geological drilling, petrochemical cracking, boiler manufacturing, bearing production, and as high-precision structural steel pipes for the automotive, tractor, and aviation industries.
