Products Description
Seamless steel pipe is a kind of metal pipe integrally formed through the process of round billet → heating → piercing → hot rolling / cold rolling / cold drawing. It has no welded seam, with dense metallographic structure and uniform mechanical properties, making it the core basic pipe material for high-end industry, high-pressure working conditions and precision machinery. The product can be customized in material, specification, process and surface treatment, with core advantages of high strength, high reliability and long service life. It is widely used in energy, chemical industry, electric power, machinery, transportation, infrastructure and other key industries of national economy.
Key Features
Structural Advantage: One-piece forming without welding seam, with excellent sealing performance, pressure resistance, torsion resistance and impact resistance, eliminating the risk of weld cracking and leakage, and ensuring strong long-term operation stability;
Precision Advantage: Uniform wall thickness, precise inner/outer diameter tolerance and good straightness, meeting high requirements of high-pressure, precision assembly and fluid transmission;
Performance Advantage: High and low temperature resistance, corrosion resistance and wear resistance, adaptable to complex and harsh working conditions such as acid-base, high/low temperature, high pressure and dust;
Customization Advantage: Support customization of material, outer diameter, wall thickness, length, end treatment and surface anti-corrosion treatment to meet the special needs of different industries.
Typical Application Fields
Energy Transportation: High-pressure transmission pipelines for petroleum, natural gas, shale gas and chemical media;
Power Boilers: High-pressure boiler tubes, superheaters, heat exchangers and thermal main pipe networks;
Mechanical Hydraulics: Hydraulic and pneumatic systems, cylinder tubes, precision mechanical structures, bearing casings and automobile drive shaft tubes;
Engineering Equipment: Mining machinery, shipbuilding, rail transit, infrastructure steel structure, oil and gas equipment, etc.
