Vipul Pipes and Tubes, a prominent brand in precision stainless steel tubing with headquarters in Chennai, India, provides premium stainless steel 321 and 321H electropolished pipes made for demanding applications requiring extremely clean, corrosion-resistant surfaces. Stabilised austenitic stainless steels, SS 321 for general high-temperature use and SS 321H for applications needing increased creep strength, are used to make these pipes. For the semiconductor, food processing, and pharmaceutical industries, the electropolishing process guarantees an internal surface that is contaminant-free and mirror-smooth. In accordance with ASTM A312 and other international standards, Vipul Pipes and Tubes consistently provides quality, dimensional accuracy, and surface purity.
Vipul Pipes and Tubes’ stainless steel 321 and 321H electropolished pipes are stabilised by the addition of titanium (≥5x C%), nickel (9–12%), and chromium (17–19%). With a higher carbon content (0.04–0.10%), SS 321H provides more creep resistance at higher temperatures. These pipes have an elongation of at least 35%, a yield strength of at least 205 MPa, and a tensile strength of at least 515 MPa. These pipes are perfect for extremely sterile and clean processing environments that demand high mechanical integrity and hygiene standards because the electropolishing process improves corrosion resistance, flattens the surface, and gets rid of microscopic impurities.
