Due to the presence of tungsten, molybdenum, chromium, and nickel these tubes tend to exhibit considerable resistance towards stress corrosion cracking and crevice corrosion. We design customized pipes and tubes keeping all National and international standards in view. Our products are noted for their durability and flexibility; thence they have a huge demand in the market. They are resistant to many oxidizing acids and oxidizing aqueous media which especially contains chlorine ions.

Our Hastelloy tubes in their available forms: threaded, electropolished, heat exchangers, hot rolled, cold rolled, heat exchangers, annealed, pickled etc. Unlike many other tubes, our UNS N Welded Tubes do not form any grain boundary precipitates though they are used in elevated temperatures. Compared to other Hastelloy tubes, these tubes are designed with extra-large dimensions. Our tubes and their available shapes: round, square, rectangular, oval, hollow etc. Hastelloy tubes of all grades and specializations are available in our stock and are ready for shipment.

Two classes of pipe are covered as Class I which is as welded and solution annealed or welded and sized and solution annealed; and Class II which is welded, cold worked, and solution annealed. All pipes shall be furnished in the solution annealed and descaled condition. The pipe shall be made from flat-rolled alloy by an automatic welding process with no addition of filler metal. Subsequent to welding and prior to final heat treatment, Class II pipes shall be cold worked either in both weld and base metal or in weld metal only.
