Technical Overview

Hastelloy C22 (UNS N06022 / DIN 2.4602) and Hastelloy C276 (UNS N10276 / DIN 2.4819) are highly alloyed nickel-based materials, known for their outstanding corrosion resistance properties. These materials conform to stringent international standards such as ASTM B622 for seamless pipes and ASTM B619 for welded pipes and tubes. The inclusion of elements like molybdenum, chromium, tungsten, and iron enhances their resistance to various forms of localized attack—including intergranular corrosion and oxidizing chlorides—commonly encountered in chemical processing industries.

Seamless pipes and tubes are typically manufactured by cold drawing from solid billets, offering a flawless internal structure and high dimensional consistency. Welded versions are fabricated from rolled plates and undergo advanced welding processes, ensuring high-quality fusion without compromising corrosion resistance. Cold-drawn pipes exhibit enhanced surface finish, improved tensile strength, and refined microstructure, making them ideal for critical assemblies and corrosive fluid systems. Electro-polishing treatments are also applied to achieve a smooth and uniform surface finish on both the internal and external walls of the pipes.

These precision-engineered pipes and tubes are available in a variety of end finishes including plain, threaded, and beveled ends. Standard supply configurations include single random, double random, and cut-to-length options, designed to suit project-specific requirements across multiple sectors.

Applications & Industry Use

The unparalleled corrosion resistance of C22/C276 Hastelloy Pipes and Tubes makes them indispensable in industries operating under extreme chemical exposure. They are extensively used in chlorination systems, acid manufacturing units, chemical reactors, pickling lines, sour gas wells, and pollution control equipment. Their performance in handling aggressive chemicals and corrosive gases also makes them ideal for scrubber systems, ductwork, stack-gas re-heaters, incinerator components, and industrial waste treatment units.

In sectors such as pharmaceuticals, pulp & paper, agrochemicals, and petrochemicals, these pipes are preferred for their long service life, low maintenance requirements, and high resistance to contamination. They are frequently found in fuel gas desulfurization plants, pesticide manufacturing facilities, and cellophane production lines, where material degradation is a critical risk.

We ensure that every product batch undergoes rigorous quality assurance checks, including hydrostatic testing, eddy current testing, and visual inspections, to meet project specifications and international compliance. Our vast experience, strategic supply network, and technical excellence make us a dependable source for Hastelloy C22/C276 Pipes & Tubes in high-demand and high-risk industrial applications across the Middle East and South Asia.
