Premium-grade Hastelloy ERW (Electric Resistance Welded) pipes made for extremely corrosive and hot conditions are available from Vipul Pipes and Tubes, a top manufacturer and supplier in Chennai, India. Mostly composed of iron, nickel, molybdenum, and chromium, the Hastelloy family of corrosion-resistant metal alloys provides exceptional resistance to harsh chemicals, particularly in oxidizing and reducing media. Our ERW pipes are produced with exceptional dimensional accuracy and consistent strength thanks to precise welding techniques. These pipes are appropriate for the waste treatment, pollution control, chemical processing, and marine industries because they meet international standards such as ASTM B619 and B775.
Depending on the grade (e.g., C22, C276), Hastelloy ERW Pipes are usually made of iron, nickel (≈55–60%), molybdenum (≈16%), chromium (≈15–22%), and trace elements like cobalt and tungsten. These alloys have remarkable resistance to stress corrosion cracking, pitting, and crevice corrosion. Mechanical characteristics include yield strength of roughly 280–350 MPa and tensile strength between 690–785 MPa. Uniform welds with superior mechanical stability and corrosion resistance are produced by ERW manufacturing. The pipes can be used in environments with high levels of acidity and chloride, where long-term reliability and durability are essential.

Yes, custom sizes are available for Hastelloy ERW Pipes to meet specific project requirements. These pipes can be tailored for various industrial applications. For more details, contact us at sales@vipulpipesandtubes.co.in.
Industries including pulp and paper, marine engineering, chemical processing, pharmaceuticals, and pollution control make extensive use of Hastelloy ERW pipes. Acid production lines, scrubber systems, heat exchangers, flue gas desulfurization units, and chemical storage and transfer piping are examples of common applications. In addition to oxidizing chlorides and wet chlorine gas, these pipes function dependably in environments containing hydrochloric, sulfuric, nitric, and phosphoric acids. They are perfect for systems that need safe, long-term fluid or gas transport under demanding operating conditions because of their high strength, formability, and resistance to corrosion.
