1.The use of the products and performanceNot only does ductile iron have high tensile strength and percentage elongation,but also have fine ductility and other excellent as anti-high-compression,
Anti-oxidation,anti-corrosion,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
2. Product standards:All types of ductile iron pipe fittings produced by us according to ISO2531 BSEN545 EN598 BS4772 standards
3. Product export countries:Europe,South America,Africa,Middle East and South-East Asia,Their good quality has got a favorable appraisal from the end users.
