 Industries & Applications of Inconel 718 Ermeto Tube Fittings

  • Petrochemical Industries
  • Gas Processing Industries
  • Oil & Gas Industries
  • Food Processing Industries
  • Fertilizers Industries
  • Power Generation Industries
  • Sugar Industries
  • Chemical Industries

 

Inconel 825 Single Ferrule Fittings Properties

  • Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion
  • Almost completely free from chloride induced stress corrosion cracking
  • High resistance to oxidation at elevated temperatures
  • Good resistance to acids, such as phosphoric, sulfuric, nitric, and hydrochloric
  • Excellent mechanical properties at both extremely high and lowtemperatures

 

Advantages of UNS N06625 Flareless Fittings

  • Size range from 1/16” to 2” (2mm to 38mm O.D.tubing)
  • Variety of end connections and patterns as per Customer Request
  • Inconel Tube Fittings do not twist the tube during installation.
  • Positive leak free seal assembly and reassembly
  • Make and remake of the fittings is very much eased, as nuts are silver plated internally to prevent galling of threads.
  • Low torque Operation
