Seamless steel pipes are crafted from whole round steel and lack any surface welds, distinguishing them as seamless pipes. Based on production methods, seamless steel pipes are classified into hot-rolled, cold-rolled, cold-drawn, extruded seamless pipes, and top pipes. They are also categorized by cross-sectional shape into round and special-shaped pipes, with the latter including square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and finned pipes. Their diameters range from a maximum of 900mm to a minimum of 4mm. Depending on their usage, seamless pipes are further divided into thick-walled and thin-walled types. These pipes serve various applications, such as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
