Used in natural gas supply networks with service line pressure of: 200mbar – 5bar. They are equipped with a drilling system and coupling can be performed regardless of whether the network is under pressure or not. The service tees are fitted (from factory) on the tee outlet with a gas stop device, which is a safety device designed to prevent explosions, personal injuries, gas losses, etc. in case of accidental rupture of the service line. The safety devices are non-self-resetting type; special reset kits available from Distrigaz Sud/ENGIE teams are required to unlock them. -Material: PE 100 SDR 11 (ISO S5) -Manufacturing standard compliant with EN 1555-1:2011. ISO 4437-3 -Manufacturing method: injection molding -Electrofusion fitting resistance is embedded in the material -Interior surfaces of fittings have smooth surfaces, without striations -Fusion temperature between -10C +45C -Fusion voltage 40 V -With integrated cutter for drilling pipes under pressure -4 mm connectors -Fusion indicators with limited displacement -Electrofusion service tees = d250 mm are supplied with a fixing clamp, attached at one end and with the tightening system at the other end. For installation, they do not require special devices, only a socket wrench is sufficient. Installation must be performed according to installation instructions by authorized personnel.
