Based in Chennai, India, Vipul Pipes and Tubes is a reputable manufacturer and supplier of 309H stainless steel pipes that provide high-performance piping solutions for corrosive and high-temperature environments. A high-carbon variant of SS 309, SS 309H is made especially to provide increased strength and resistance to creep at high temperatures. Vipul Pipes and Tubes is renowned for providing high-quality products that satisfy global standards, supported by sophisticated manufacturing processes and meticulous quality assurance. The business guarantees prompt delivery, precise engineering, and client satisfaction in India and international markets while catering to sectors like petrochemical, power generation, and thermal processing.
Iron, 22–24% chromium, 12–15% nickel, and a higher carbon content (0.04–0.10%) than regular 309 make up the majority of stainless steel 309H pipes, which improves their strength at high temperatures. Small amounts of silicon, phosphorus, and manganese are also present in the alloy. Up to 1000°C, SS 309H pipes show outstanding resistance to scaling and oxidation. Mechanical characteristics include an approximate elongation of 40%, a yield strength of 205 MPa, and a tensile strength of 550 MPa. Because of these characteristics, it can be used in applications that require thermal cycling and extended exposure to high temperatures.
