Flanged insulating connections

Designed for electrical separation of pipelines from other underground structures or individual sections of pipelines from other areas. They are used to eliminate or limit stray currents in underground pipelines induced by grounding of direct or alternating currents and high voltage transmission lines, as well as to eliminate the dispersion of protective currents of electrochemical (mainly sacrificial) protection. Flanged insulating connections are designed for pipelines operating under pressure up to 4.0 MPa (low pressure), with a corrosion-resistant protective coating with a thickness of up to 0.45 mm. The main dimensions of the IFS low pressure: Ru, MPa - 4 max l, mm - 125 De, x S mm - L, mm 89x4 - 1046 114x4.5 - 1066 159x6 - 1091 219x6 - 1246 273x7 - 1431 325x8 - 1561
