Esen Drainage Pipes are circular-section spiral products which collect water in places where the level of ground water is high and transfer them to any desired places thanks to their properties. Made of rigid PVC, the drainage pipes are produced in conformity with TSE 9128 and DIN 1187 standards and have inner diameters from 44mm to 182mm. Coil sizes may be adapted to the machines laying draining pipes. Esen Drainage Pipes have a minimum 8 cm2 water intake opening per meter so that ground waters may be best collected. Esen Draining Pipes are firm and aesthetic. They are resistant to friction and crushing.
