Used in natural gas supply networks with branch pressures 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 tapping tees are fitted (from factory), on the tapping tee outlet, with the gas stop device, which is a safety device designed to prevent explosions, personal injuries, gas losses, etc. in case of accidental rupture of the branch pipe. The safety devices are of the non-auto-reset 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 material -Interior surfaces of fittings have smooth surfaces, without striations -Welding temperature between -10C +45C -Welding voltage 40 V -With integrated cutter for drilling pipes under pressure -4 mm connectors -Welding indicators with limited displacement -Electrofusion tapping 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.
