ASTM A333 Grade 6 Low Temperature Carbon Steel Pipe – Factory Direct Supplier
Our Low Temperature Carbon Steel Pipe is engineered to maintain toughness at temperatures as low as -50°C to -196°C, strictly complying with ASTM A333 Grade 6 and A420 WPL6 standards. Designed to prevent brittle fracture in cryogenic and cold climate applications, it is the preferred choice for global LNG plants, petrochemical facilities, and arctic engineering projects.
We supply low temperature carbon steel pipes specifically engineered to maintain toughness and structural integrity in cold climates and cryogenic applications. Manufactured with fine-grained steel and optimized alloying, our pipes deliver excellent impact resistance at temperatures as low as -50°C to -196°C, preventing brittle fracture in demanding low-temperature service.
Exceptional Low-Temperature Toughness: High impact resistance at specified sub-zero temperatures
Fine-Grained Structure: Controlled rolling and normalization ensure uniform microstructure for reliable performance
Weldability & Processability: Can be welded and fabricated using standard procedures suitable for low-temperature service
Standard Compliance: Meets ASTM A333 Grade 1, Grade 6, A420 WPL6, and equivalent international specifications
Ideal for LNG systems, cryogenic storage, refrigeration plants, arctic pipelines, and chemical processing in cold environments. We offer custom cutting, beveling, non-destructive testing, and full certification with impact test reports.
【Key Features & Applications】
Exceptional Cryogenic Toughness: Charpy V-Notch impact tested at -50°C, ensuring high safety standards in extreme low-temperature environments.

Our seamless carbon steel pipes are manufactured from high-quality materials complying with international standards including ASTM A106, API 5L, and ASTM A53. These pipes feature excellent pressure resistance and durability, making them ideal for oil & gas, petrochemical, and high-pressure fluid transportation applications. Custom lengths and end treatments are available to meet specific project requirements.
Produced using precision hot-rolled or cold-drawn processes, our seamless pipes undergo strict quality control during piercing, elongation, and sizing. Equipped with automated ultrasonic testing (UT) and eddy current inspection systems, we ensure consistent wall thickness (±10%) and superior internal/external surface quality.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
【FAQ】
Q: What is the difference between A333 Gr.6 and standard A106 pipe?
A: A333 Gr.6 is specifically impact tested for low temperatures (-50°C), while A106 is designed for high temperatures. Using A106 in cold environments risks catastrophic brittle fracture.
Q: Can you provide custom lengths?
A: Yes, we cut to exact lengths per your project drawings, and we provide full traceability with MTC and Impact Test Reports.
