Product Description - Seamless Steel Pipe Tube
Seamless steel pipes are formed by perforating a whole round steel bar. Pipes without welds on their surfaces are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into circular and special-shaped types. Special-shaped pipes have various complex shapes such as square, oval, triangular, hexagonal, oval-shaped, star-shaped, and winged pipes. The maximum diameter can reach 900mm, and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as drilling pipes for petroleum geology exploration, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

Processing Flow
Main production processes (main inspection processes) of hot-rolled seamless steel pipes: Preparation and inspection of pipe billets → Heating of pipe billets → Piercing → Rolling of pipes → Reheating of steel pipes → Setting (reducing) of diameter → Heat treatment → Straightening of finished pipes → Finishing → Inspection (non-destructive, physical, on-site inspection) → Storage Main production processes of cold-rolled (drawn) seamless steel pipes: Preparation of billets → Acid washing and lubrication → Cold rolling (drawing) → Heat treatment → Straightening → Finishing → Inspection
Advantages
High strength: No welds, highly integrated, resistant to high pressure, suitable for extreme environments.
Uniform and reliable: The material is dense, the mechanical properties are stable, and the service life is long.
Corrosion-resistant: Surface treatment available, suitable for humid and chemically corrosive environments.
Precise and smooth: High dimensional accuracy, smooth inner walls, low fluid resistance.
Wide applicability: Multiple material options available, easy to process, suitable for various needs.
Lightweight economy: High strength-to-weight ratio, low long-term usage cost.
Applications
Oil/Gas: Drilling, High-pressure Transportation
Electricity: Boiler, nuclear power pipelines
Chemical/Pharmaceutical: Corrosion-resistant, clean pipelines
Mechanical components: hydraulic cylinder, bearing, transmission shaft
Automobile/Airplane: Axles, fuel pipes, landing gear
Architecture: Bridges, high-rise structure supports
Product Category
Continuous steel pipes without joints along their cross-sectional periphery. Depending on the production method, they are classified as hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and pipe jacks, each with its own process specifications. The materials include ordinary and high-quality carbon structural steel (Q215-A to Q275-A and 10 to 50 grade steel), low-alloy steel (09MnV, 16Mn, etc.), alloy steel, and stainless acid-resistant steel, etc. According to their uses, they are divided into general-purpose ones (used for water and gas pipelines, structural components, mechanical parts) and specialized ones (used for boilers, geological exploration, bearings, acid resistance, etc.).
