Special-shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the shape and size of the cross-section of the steel pipe, it can be divided into special-shaped seamless steel pipes with equal wall thickness (code-named D), special-shaped seamless steel pipes with different wall thickness (code-named BD), and special-shaped seamless steel pipes with variable diameter (code-named BJ).

Cold-drawn or cold-rolled precision seamless steel pipes for hydraulic equipment with high dimensional accuracy and good surface finish. Precision seamless steel pipe is used to manufacture mechanical structures or hydraulic equipment, etc., and the precision steel pipe is a high-precision seamless steel pipe processed by cold drawing or cold rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipes, no leakage under high pressure, high precision, high smoothness, no deformation in cold bending, flaring, and no cracks in flattening, it is mainly used to produce pneumatic or hydraulic products.

Oil casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well uses several layers of casing according to different drilling depths and geological conditions. Cement cementing is used after the casing is lowered into the well. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes.
Casing can be divided into: conduit, surface casing, technical casing and oil layer casing according to the usage.
