Vipul Pipes and Tubes in Chennai, India, is a prominent manufacturer and supplier of Stainless Steel 316H Seamless Pipes. The pipes are specifically made for use under high temperature and high pressure where higher strength and corrosion resistance are required. SS 316H is a high-carbon variant of the 316, offering improved creep resistance and mechanical strength at higher temperature levels. Our stainless steel seamless pipes are manufactured with high-quality raw material and strict quality control, providing high dimensional accuracy and long service life. They have extensive applications in refineries, power plants, petrochemical plants, and chemical processing industries where the users require efficient high-performance piping solutions.
Stainless Steel 316H Seamless Pipes contain 16–18% Chromium, 10–14% Nickel, and 2–3% Molybdenum that enhance corrosion and pitting resistance. Carbon content is 0.04–0.10%, which provides high-temperature strength. Other contents are Manganese (≤ 2.00%), Silicon (≤ 1.00%), Phosphorus (≤ 0.045%), and Sulfur (≤ 0.03%). These pipes provide minimum tensile strength as 515 MPa, yield strength as 205 MPa, and elongation as 35%, and these are ideal for thermal and mechanical stress conditions in various critical industries.

Stainless Steel 316H Seamless Pipes are used widely in industrial settings at high temperatures where strength and resistance to corrosion are needed. Some of the common uses are heat exchangers, superheaters, boilers, pressure vessels, and furnace components. They find best application in oil refineries, power plants, chemical processing plants, and nuclear power plants where structural integrity and performance at high temperatures are a priority. Higher carbon content provides excellent creep resistance, and molybdenum content provides resistance to stress corrosion by chlorides. Seamless pipes SS 316H are also ideal for fabrication and welding processes in systems subjected to high pressure and thermal cycles.
