Product Introduction

  Seamless steel pipes are manufactured by piercing a solid round steel billet, resulting in a pipe with no visible weld seams on its surface—hence the term "seamless steel pipe." Depending on the production method, seamless steel pipes can be categorized into hot-rolled, cold-rolled, cold-drawn, extruded, and mandrel-pushed types. Additionally, based on their cross-sectional shapes, seamless steel pipes are divided into two main types: circular and special-shaped. Special-shaped pipes include complex profiles such as square, oval, triangular, hexagonal, melon-seed shaped, star-shaped, and finned tubes, among others.
