We manufacture and supply ductile iron pipe fabrications from 80mm-1200mm. We supply all sizes possible from short double spigots to longer double flanged pipes. All our pipework is available in BS EN545 blue and BS EN598 red.
1The 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.
