Seamless steel pipes have a wide range of applications. Ordinary seamless steel pipes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, these seamless steel pipes have the largest production volume and are mainly used as pipes or structural parts for conveying fluids. Seamless steel pipes with specialized roles include seamless steel pipes for boilers, chemical and electric power, seamless steel pipes for geology and seamless steel pipes for petroleum and many others. In addition, because seamless steel pipe has a hollow cross-section, it can be used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. In addition, seamless steel pipes are also widely used in the manufacture of structural and mechanical parts, such as oil drilling rods, automobile drive shafts, pedal car frames and steel scaffolding used in building construction.
