Flange Insulation Kits (FIK)
Price-list available on request »»»

Description: FIK is a composite flange joint completed with insulating elements that ensure interrupting conductivity of the metal pipe line

 

Typical application: electrochemical anticorrosion protection systems in the underground gas pipelines

 

Characteristics:

  • Environmental conditions:
    U2 – for moderate environment without direct impact of meteorological precipitation
    XL2 – for cold environment without
    direct impact of meteorological precipitation
  • Types of the sealing surface:
    1/1 – flat-faced flange
    2/3 – raised face flange
