Professional Manufacturing Process: Precision from Molten Steel to Finished Pipe
The production of ASTM A333 low temperature steel pipes follows a rigorously controlled workflow:
Material Selection & Melting
High-purity iron ore, carbon, manganese, silicon, and nickel (for Grade 6/9) are melted in electric arc furnaces.
Composition is adjusted to meet strict low-temperature impact toughness requirements (e.g., Charpy V-notch testing at -45°C).
Forming Process
Seamless Pipes: Billets are heated to 1,200°C and extruded via rotary piercing or mandrel mills.
Welded Pipes: Plates are formed into cylinders using UOE (U-ing, O-ing, Expansion) or JCOE presses, then longitudinally welded via submerged arc welding (SAW).
Heat Treatment
Pipes undergo normalization (heating to 900°C followed by air cooling) or quenching and tempering (for Grade 3/9) to refine grain structure and enhance impact strength.
Testing & Certification
Non-Destructive Testing (NDT): Ultrasonic (UT), radiographic (RT), and hydrostatic tests detect flaws.
Mechanical Verification: Tensile strength, yield strength, and elongation tests per ASTM A370.
Impact Testing: Charpy tests at designated temperatures (e.g., -196°C for LNG applications).
