Product Description

Oil Refinery ASTM/ASME A/SA333 Gr.B Low-Temperature Carbon Steel Pipe for Heat Exchanger

Product Description

 

Our ASTM/ASME A333 Gr.B carbon steel pipes are specifically engineered for low-temperature applications in oil refineries, petrochemical plants, and heat exchangers. These pipes offer excellent toughness at sub-zero temperatures, making them ideal for cryogenic fluid transport, LNG systems, and refinery heat exchange units.

Key Features & Benefits

 Low-Temperature Performance - Certified for service down to -45°C (-50°F) without brittle fracture risk.
 High Impact Resistance - Charpy V-notch tested to ensure ductility in freezing conditions.
 Heat Exchanger Optimized - Smooth internal surface minimizes fouling & maximizes thermal efficiency.
 Weldability & Fabrication-Friendly - Low carbon content (0.30% max) reduces preheat requirements.
 Compliance with Rigorous Standards - Meets ASTM A333 (ASME SA333) for seamless & welded pipes.
