Nickel Alloy Coiled Tubes

Product Overview

Nickel Alloy Coiled Tubes are engineered for demanding applications in heat exchangers, reactors, and cryogenic systems across oil & gas, chemical, aerospace, and energy industries. Made from ​Inconel 625, ​Hastelloy C-276, and ​Alloy 800, and compliant with ​ASTM B163, ​ASME SB622, and ​EN 10216-5 standards, these coils deliver superior resistance to thermal fatigue, oxidation, and corrosive media like chlorides, acids, and seawater.
