flanged pipes for fittings

Detailed Product Description

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
