Features and Benefits
Ductile Iron is a form of cast iron characterised by the spheroidal or nodular form of the graphite content. The spheroidal graphite inhibits crack growth and results in improved ductility in comparison to grey cast iron which has flake graphite.
Ductile Iron fittings are manufactured from Ductile Iron with a minimum tensile strength of 400MPa and a minimum elongation of 12%. Maximum Brinell hardness is 250 HB.
Thermally Bonded Polymeric External coating and Internal lining
All ductile iron fittings supplied by Vinidex are externally coated and internally lined with a thermally bonded polymeric coating for excellent corrosion resistance. Depending on the size of the fitting, the coating may be either a nylon or epoxy material complying with AS/NZS 4158.
Superlink Deep Sockets
The opportunity for socket withdrawal relies on a number of factors, chamfer length, squareness cut of pipe end, contraction due to temperature differential, Poisson contraction of pipe when pressurised and how well the pipeline is constructed.
The Vinidex Superlink II range of ductile iron fittings has the deepest socket entry available in Australia. They are suitable for all pipe materials in all classes, Supermain PVC-O, Hydro PVC-M, PVC-U, Series 2 GRP or ductile iron.
Ductile Iron fittings with rubber ring joints are capable of the joint deflections listed in the following table.
|100 – 250||3½°|
|300 – 600||2½°|
Allowable Operating Pressure
Allowable pipeline pressures for Ductile Iron fittings are as listed in the table below. Note that the allowable operating pressure in a pipeline system is limited to the pressure rating of the lowest rated component in the system.
|PN||Allowable Operating Pressure (AOP) MPa||Maximum Allowable Operating Pressure (MAOP) MPa||Allowable Site Test Pressure (ASTP) MPa|
