Factory Introduction

Last updated: May 3, 2026

Xenith Steel's stainless pipe facility on a 40,000sqm site in Cangzhou produces both seamless (cold-drawn/cold-rolled) and welded (TIG/plasma + cold-rolled) stainless pipes OD 6-720mm at 40,000 tons/year with 220+ specialized workers. The plant operates LG cold rolling mills, bright annealing furnaces under hydrogen atmosphere, pickling and passivation lines, and full NDT including eddy current, ultrasonic, and hydrostatic stations. Certified API Q1, ISO 9001:2015, PED 2014/68/EU. Manufactures to ASTM A312/A269/A249/A213 in austenitic (304/L, 316/L, 310S, 321, 347), duplex (S32205, S31803), super duplex (S32507, S32750), and nickel alloys (400, 600, 800). ArcelorMittal, Outokumpu, Thyssenkrupp, TechnipFMC, and Tenaris source from this plant for corrosive-service and high-temperature applications in petrochemical, pharmaceutical, and power generation.
