Material OverviewThe ASTM A334/A334M Grade 6 Seamless Pipe is a low-temperature carbon steel pipe designed for cryogenic and sub-zero temperature applications. Compliant with the ASTM A334/A334M standard, it ensures exceptional toughness and reliability in environments down to -45°C (-50°F). 2. Key FeaturesMechanical PropertiesYield Strength: ≥240 MPa (35 ksi)Tensile Strength: 415-585 MPa (60-85 ksi)Elongation: ≥30% (ensures ductility under stress).Impact Toughness: Charpy V-notch tested at -45°C to meet low-temperature performance requirements.Chemical CompositionCarbon (C): ≤0.30% (balances strength and weldability).Manganese (Mn): 0.29-1.06% (enhances toughness).Silicon (Si): 0.10-0.35% (improves oxidation resistance).Phosphorus (P): ≤0.025% | Sulfur (S): ≤0.025% (minimizes brittleness).Manufacturing ExcellenceSeamless Construction: Produced via hot extrusion or rotary piercing, eliminating weld seams and enhancing structural integrity.Heat Treatment: Normalized or normalized-and-tempered to refine grain structure and optimize low-temperature toughness. 3. Technical ComplianceASTM A334/A334M Standard: Guarantees compliance with dimensional tolerances, testing protocols, and material properties.Low-Temperature Certification: Certified for use in cryogenic applications (e.g., LNG systems, refrigeration).NDT Requirements: Ultrasonic testing (UT) or hydrostatic testing ensures defect-free pipes. 4. ApplicationsCryogenic Systems: LNG pipelines, liquid nitrogen/oxygen transport.Oil & Gas: Subsea pipelines, Arctic drilling equipment.Chemical Plants: Low-temperature process piping.Power Infrastructure: Cooling systems and cryogenic storage. 5. Quality AssuranceFull Traceability: EN 10204 3.1/3.2 material certification with batch-specific test reports.Non-Destructive Testing (NDT): Mandatory ultrasonic or hydrostatic testing to ensure zero defects.Impact Testing: Charpy V-notch tests at -45°C validate low-temperature toughness. 6. AdvantagesExceptional Low-Temperature Performance: Maintains ductility and strength in extreme cold.Seamless Reliability: No weld seams reduce risks of leaks or weak points.Weldability & Fabrication Flexibility: Compatible with standard welding techniques (e.g., TIG, MIG).Global Compliance: Meets ASTM, ASME, and PED standards for international projects.
