Sleeve pipe

Material: ductile iron

Centrifugal ductile iron pipes are ideal for the water and gas supply pipelines of municipal administrations, industrial and mining enterprises and cities, featuring high strength, good flexibility, corrosion resistance and easy installation. With the nature of iron and performances of steel, it is the replacement of traditional cast iron pipes and common steel pipes. The company annually produces more than 200,000t ductile iron pipes with specifications from DN80 to DN1600mm.
