Key Features of UNS N05500 Monel K500 Pipe Fittings

UNS N05500 Monel K500 Pipe Fittings have a maximum operating temperature of -200degF as well as being spark resistant, resulting in their use in sour gas wells, marine seawater service, aerospace hydraulic systems and in oil and gas downhole equipment. The tensile properties of the alloy can be retained to 1200degF. High tensile strength of precipitation hardening combined with low corrosion rates of high velocity seawater make Monel K500 fittings better than Monel 400 in service in the demanding marine and energy-sector. 

Applications of Monel K500 Pipe Fittings

  • Offshore platform piping and marine seawater service lines
  • Oil & gas sour gas wells and downhole completion equipment
  • Aerospace hydraulic systems and aircraft components
  • Chemical plant piping for hydrofluoric acid service
  • Pump shafts, impellers, and marine heat exchangers
