Sewage and Water Disposal Systems
Pressure sewage systems
Storm water systems
Ductile iron pipelines allow to solve the task with the sewerage liquid transportation on big distances from the living apartments to effluent treatment plants providing high reliability leakproofness and durability of water disposal system.
For sewerage pipelines of different purposes Svobodny Sokol offers socket joint pipelines and fitting made of ductile iron and corresponding to Europe standards EN 598 DN 80-1000 mm.
The leakproofness of the socket- straight end connection is reached with the compression or the resin gasket. The materials used while gasket manufacture process passed all the necessary selection and tests in regarding with the possibility of saving all the physico-mathematical characteristics in case of contacting with aggressive soil condition.
For pipeline internal protection can be used the lining based on portland-cement, sulphate -resistant cement and high-alumina cement depending on aggressive liquid transportation influence
The choice of the internal lining should be considered according to EN 545 an EN 598 standards.
Outer coating of the ductile iron pipelines:
Zinc metal or zinc-alumina coating together with finishing layer according to ISO 8179-1.
