3 Arguments to convince you You need to be certain that sewage will arrive safely at the point where it is going to be treated. By using ductile iron sewer pipes you have this certainty and safety. Why are ductile iron sewer pipes safe? Because they are fully sealed. Groundwater cannot get into the sewer. The sewage cannot escape and contaminate the ground because the material and the joints stop it from doing so. It is easy for sewer pipes to carry the high external loads generated by soil pressure and traffi c loads. Sewage is corrosive but that is no problem for Duktus ductile iron pipes because the lining of high-alumina cement mortar means that the pipes are armed even against severe biogenic sulphuric acid attack. Even acid, highly lime-dissolving or sulphate-rich sewage cannot do anything to the pipes or joints. The lining maintains its abrasion resistance even at high rates of fl ow such as may occur in steep sections of the pipeline. Put your money on ductile iron, this innovative material, when the safety of your sewers is at stake. Ductile iron pipes have long been state of the art for transporting drinking water, our most valuable nutritional resource just one more proof of the material s outstanding properties F BLS fitting Flanged spigot Duktus ductile iron sewer pipes and fi ttings can be used almost anywhere, including for gravity pipelines and for pipelines running through water protection zones. And Duktus sewer pipes will also provide the right system-based solution for almost all special applications. All fi ttings for drinking water can be used for sewer pipelines.
