ELOFIT INCHES BUTT FUSION REPAIR SLEEVE (EIBFRS) is a safety repair system to be used when, in service, butt-welding cannot be guaranteed, or to repair minor damages on pipe. EIBFRS can be installed on pressurized pipe made out of PE4710, PE3408, PE2708 and PE2406. EIBFRS must be installed on pipes without fl uid leakage. The maximum network pressure allowed to weld the EIBFRS on the pipe depends of the polyethylene grade and SDR of pipe
