Not only does the ductile iron have high tensile strength and percentage elongation,but also have fine ductility and other excellent quality as anti-high-compression,antioxidation,anticorrosion,etc.So the Ductile Iron Pipe Fittings are widely applied to such compressive pipes as water pipeline,oil pipeline,gas pipeline,sand pipeline,sewerage pipeline,etc.All types of Ductile Iron Pipe Fittings produced by us according to ISO2531,EN545,AWWA C110 have been largely exported to many countries and regions in Europe,America and South-East Asia,Their good quality has got a favorable appraisal from the end-users.
