Seamless steel pipe types

Seamless steel pipes come in various types, each with unique production methods and characteristics. Understanding these types can help in selecting the appropriate material for specific applications. Read on to learn more about the types of seamless steel pipe.

Cast Steel:

This type of steel is produced through casting methods. Cast steel is primarily used for manufacturing complex-shaped parts that are difficult to forge or machine, but still require high strength and plasticity.

Forged Steel:

Produced through forging methods, forged steel includes various forging materials and forgings. Forged steel generally has higher quality than cast steel, with superior impact resistance, plasticity, and toughness. It is preferred for critical machine parts in the petroleum industry.

Hot Rolled Steel:

Hot rolled steel encompasses all types of steel produced via hot rolling methods. Most steel products, such as section steel, seamless steel tubes, and steel plates, are made through hot rolling. This method is also used for rolling wire rods.

Cold Rolled Steel:

This type of steel is produced by cold drawing methods. Cold rolled steel has a smooth surface, precise dimensions, and excellent mechanical properties compared to hot rolled steel. It is typically used for producing thin plates, steel strips, and seamless steel tubes.

Cold Drawn Steel:

Produced by the cold drawing method, cold drawn steel is known for its high precision and good surface quality. It is mainly used to produce steel wire, round steel, alloy hexagonal steel with a diameter less than 50mm, and steel pipes with a diameter less than 76mm.
