Material: Steel pipes are usually made of carbon steel or low-alloy high-strength structural steel. Common materials include Q235 and Q345.
Application areas: Steel pipes are widely used in construction engineering, oil and gas pipelines, machinery manufacturing, automotive industry and other fields. They are used to transport liquids or gases, as structural supports, and to manufacture various equipment and components.
Steel pipe is a hollow, long steel strip with a round, square or rectangular cross section. Steel pipe can be divided into welded steel pipe and seamless steel pipe. Welded steel pipe is formed by rolling steel plates into a tube and welding them, while seamless steel pipe is made from solid steel billet by extrusion or perforation. Steel pipe has good strength and corrosion resistance and is widely used in various load-bearing and transportation applications.
