Pipe for low-temperature equipment

Pipe for Low-Temperature Equipment

Product Overview:
Low-temperature pipes are specially engineered to maintain excellent strength, ductility, and toughness under sub-zero conditions. These pipes are commonly used in environments where temperatures fall below -29°C (-20°F), such as cryogenic systems, LNG plants, and cold storage infrastructure. Made from fine-grain, impact-tested steels, they ensure safety and performance in extreme cold.

Key Features:

• Material Grades:

• ASTM A333 Grade 1/3/6

• ASTM A312 TP304L/316L (for stainless applications)

• Low-alloy steels (e.g., 09MnNiDR, 16MnDR)

• Size Range: OD 1/2"–48" (DN15–DN1200)

• Wall Thickness: SCH10 to SCH160 / STD / XS / XXS

• Temperature Rating: Suitable for service down to -196°C (cryogenic grades)

• Standards: ASTM, ASME, EN, DIN, GB/T, ISO

• Surface Finish: Black paint, galvanized, pickled and passivated, or custom-coated

Advantages:

• Excellent impact resistance and toughness at low temperatures

• High weldability and structural integrity

• Long service life in cryogenic and sub-zero environments

• Available in seamless or welded form

• Fully tested (Charpy impact, hydrostatic, NDT, etc.) for safety assurance

Applications:

• LNG and LPG pipelines and terminals

• Cryogenic equipment and storage tanks

• Petrochemical and refinery units

• Low-temperature gas distribution systems

• Cold climate industrial facilities and shipbuilding

Customization Options:

• Cut-to-length services

• End types: plain, beveled, threaded

• Additional testing (impact test @ -196°C, UT, RT)

• Third-party inspection (SGS, BV, etc.) and export packaging
