Rithav Pipes and Tubes is a trusted name in Delhi, India, known for manufacturing and supplying top-notch Stainless Steel 309H Pipes. These pipes are designed to perform exceptionally well in high-temperature and corrosive environments. SS 309H, a high-carbon variant of SS 309, is specifically engineered to provide enhanced strength and creep resistance when the heat is on. Perfect for structural applications in demanding processes, our pipes meet international standards like ASTM A312, ensuring they offer remarkable oxidation resistance and mechanical stability. At Rithav Pipes and Tubes, we pride ourselves on delivering reliable, durable, and precisely crafted stainless steel piping solutions for industries such as petrochemical, power, and refining.
Stainless Steel 309H Pipes are made up of Chromium (22–24%) and Nickel (12–15%), along with a higher Carbon content (0.04–0.10%) that boosts their strength and creep resistance at high temperatures. They also include controlled amounts of Manganese, Silicon, Phosphorus, and Sulfur. With a minimum tensile strength of 75,000 psi and a yield strength of 30,000 psi, these pipes can withstand oxidation up to 1038°C and excel under thermal cycling. At Rithav Pipes and Tubes, we ensure that every pipe goes through rigorous quality testing and adheres to ASTM A312 specifications, guaranteeing optimal performance and a long service life.
