seamless steel1.jpg

Seamless steel pipe is created by perforating the entire round steel, and steel pipe with no weld seam on the surface is referred to as seamless steel pipe. Seamless steel pipes are classified into four types based on their manufacturing method: hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. Seamless steel tubes are classified into two types based on their cross-sectional shape: round and special-shaped. Special-shaped tubes come in a variety of complex shapes such as square, oval, triangular, hexagonal, melon-shaped, star-shaped, and finned tubes. The greatest diameter is 900mm, with a minimum diameter of 4mm. There are thick-walled seamless steel pipes and thin-walled seamless steel pipes for various applications. Seamless steel pipes are primarily used in petroleum geological drilling pipes, petrochemical industry cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
