Rithav Pipes and Tubes, located in Delhi, India, is a well-respected manufacturer and supplier of Carbon Steel A333 Grade 8 Pipes. We specialize in high-quality seamless pipes that are specifically designed for low-temperature service applications. Our Grade 8 pipes are crafted in line with ASTM A333 standards, ensuring they perform reliably even in extreme cold, showcasing remarkable toughness and strength. These pipes are perfect for cryogenic operations and low-temperature pressure systems across various industries, including LNG, petrochemical, oil & gas, and power generation. At Rithav, we focus on delivering quality products on time while fully adhering to international standards, guaranteeing durable and trustworthy pipe solutions.
ASTM A333 Grade 8 Pipes are made from low-alloy carbon steel and include nickel to boost toughness in low temperatures. The typical makeup features carbon (≤0.13%), manganese (0.90–1.60%), phosphorus (≤0.025%), sulfur (≤0.025%), and nickel (3.2–3.8%). These pipes boast impressive mechanical properties, with a minimum tensile strength of 450 MPa (65 ksi) and a yield strength of 240 MPa (35 ksi), along with high impact resistance even at -100°F (-73°C). To enhance their ductility and resilience in low temperatures, Grade 8 pipes are either normalized or tempered, making them ideal for cryogenic applications and harsh operating environments.
