We are a manufacturer of flange spool pipe fittings in stainless steel, carbon steel, and nickel alloys.
C&N Hongcheng is a specialist manufacturer of prefabricated components for use in pipeline systems. Prefabricated piping spools are produced using pipes, elbows and flanges in accordance with the ANSI B16.5/B16.9 standard. Pre-assembled double-flanged pipe spools reduce the fabrication time for the petrochemical, refinery and oil and gas industries. Contact us for pipe spool fabrication work of all types in China.
