Stainless steel pipes are premium corrosion-resistant tubular products manufactured from high-quality austenitic, duplex, and super duplex stainless steel grades. Available in seamless (pierced from solid billet) and welded (formed from stainless steel strip/plate) constructions, these pipes offer exceptional resistance to oxidation, acids, chlorides, and extreme temperatures.
Grades 304/304L provide excellent general corrosion resistance for most applications. 316/316L with added molybdenum offers superior pitting and crevice corrosion resistance in chloride environments. Duplex grades 2205 and 2507 deliver twice the strength of austenitic grades with outstanding stress corrosion cracking resistance. Widely used in chemical processing, oil & gas, pharmaceutical, food & beverage, marine, and architectural applications.
