8 Advantages of Ductile Iron Pi pes - Inherent resistance of ductile iron adainst corrosionalong with improvement of this resistance via various coatings - Appropriate resistance againts pressures such as water hammer and external pressure like traffic loads and etc. -Suitable for use in loose ground with high level of subterranean water - Resistance against electrical currents due to use of rubber gasket at the joint points - Adequate resistance against damages caused by displacement and transportation - Flexibility and adaquate resistance against landslide,on faults and earthquake-prone region - Great potential for cuttuing and reaming - Appropriate for mountainous areas due to lack of need for especial bedding and precise considferation of soil compaction and trench depth - High working pressures comparing to other types of pi pe - ow-pressure drop as a result of lower pumping cost due to larger actual inside diameters 1 and C coefficient of the pi pes years of lifetime Application Areas of Ductile Iron Pi pes - Potable water pi pelines - Industrial and domestic sewerage networks - Conveying of sea water - Irrigation and drainage networks - Water treatment plant networks - Firefighting systems - Artificial snow making machine -3-

10 Wall Thickness The minimum wall thickness of fittings is 7mm, limit deviation is -2,3mm The nominal wall thickness e=k(0,5+0,001dn), limit deviation is -(2,3+0,001DN)mm The nominal wall thickness of different size fittings are listed in below table: in mm Note: The lower limit only is given, so as to ensure sufficient resistance to internal pressure Pressure Test The pressure test shall be carried out on all fittings before the application of their external and internal coatings, except for the metallic zinc coating of pipes which may be applied before the test. No leakage or sweating should be detected during test. DN (mm) Mininmum Works Test Pressure (bar) Not: The works hydrostatic test pressure is less for fittings than for pipes because the shape of the fittings makes it difficult to provide sufficient restraint to high internal pressure the test. -5-

11 ining Fitting arre supplied with manually applied cement mortar lining, the mortar of the lining is composed of cement, sand and water. The mortar contains by mass minimum one part of cement to 3,5 parts of sand. The nominal thickness of the lining and the minimum permissible values are given the table below. DN (mm) Nominal ining Thickness (mm) Minimum at One Point (mm) , , Note: The surface of the cement mortar lining shall be uniform and smooth. Trowel marks, protrusion of sand grains and surface etexture inherent to the method of manufacture are acceptale. Stroge of fittings in hot, dry environment can cause metal expansion and mortar shirinkage which can result in dry lining developing areas of disbondment and shrinkage cracks exceeding the above given width. When the lining is re-exposed to water, it will swell by absorption of moisture and cracks qill close to conform to above table and will eventually heal by autogenous process. Coating A layer of zinc-rich coating+bitumen shall be uniformly covered the whole surface of the casting and have a smooth regular appearance. The mean mass of zinc rich painting shall not be less than 200g/m², the mean thickness of the coating shall be not less than 70 μ m and the local minimum thickness shall be not less than 50 μ m. -6-

13 Standard 4. Metallik Zinc Coating When metallic cinc spray is applied, the mean mass of the zinc per unit area shall be not less than 130 g/m with a local minimum of 110 g/m. The mass of the zinc according to customer`s request is also available Bitumen Coating The mean thickness of bitumen coating shall be not les than 70 µm and local minimum thickness shall be not less than 50 µm. The thickness of bitumen coating according to the customer`s request is also available. The ductile iron pipes are manufactured according to ISO 2531(Ductile iron pipes, fittings and accessories for pressure pipelines); EN545 (Ductile iron pipes, fittings and accessories and their joints for sewerage applications); Cement mortar lining are applied according to ISO 4179 (Ductile iron pipes for presure and non-pressure pipelines Centrifugal cement mortar lining General requirements); Zinc coating are applied according to ISO (Ductile iron pipes-external coating-part 1: Metallic zinc with finishing layer). 6. Alternative Coating a) External coatings: - Metallic zinc with finishing layer, in accordance with ISO ; - Zinc rich paint with finishing layer, in accordance with ISO ; - Epoxy coating, in accordance with EN 14901; - Polyethylene sleeve, in accordance with ISO 8180; - Alloy of zinc and aluminum with or without other metals, having a minimum mass of 400 g/m2, with finising layer; - Extruded polyethylene coating in accordance with EN 14628; - Polyurethane coating in accordance with EN 15189; - Cement mortar coating in accordance with EN 15542; - Adhesive tape; b) Internal coating (linings): - Portland/Blast furnace slag/sluphate/high aluminum cement mortar, in accordance with ISO 4179; - Cement mortar lining with seal coat, in accordance with ISO 16132; - Epoxy coating, in accordance with EN 14901; - Polyurethane lining in accordance eith EN 15655; c) Coating of the joint area: - Epoxy coating; - Polyurethane coating. -8-
