Area of appliance:
Appliance of Peštan PE SPIRAL pipes is visible in big sewage systems (in main collectors for the whole cities) like in the big gravitational systems of water supply where big diameters are wanted for. These pipes are by it’s structure exclusively ment for gravitational drainage or water supply. For the correct installment of Peštan pipes please follow guidelines and instruction EN 1610. For more detailed information please contact out technical support.
Connecting the SPIRAL pipes:
Peštan PE SPIRAL pipes are being connected with electro fusion belt-ring or thermally shrinkable foil. In both cases additional welding with handy extruder is necessary. It is possible to use both methods of connecting, firstly put electro fusion belt and then after put the thermally shrinkable foil over it, with OBLIGATORY welding with handy extruder inside.
