It is divided into round, square, rectangular and special-shaped steel pipes according to its cross-sectional shape; it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes according to its material. Pipes are not only used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers, but also required for construction operations during construction sites. Rust will form on the outside of the steel pipe if it is not used for a long time, which requires a rust remover to remove the rust.
