Ductile Iron Pipes

Short Description:

The ductile iron pipes are manufactured according to ISO2531/EN545/EN598/NBR7675 international standard. Ductile cast iron is a kind of alloy of iron, carbon and silicon. During production process, we carry out tests on line strictly and test items includes: hydraulic pressure, cement lining thickness, zinc spraying thickness, bitumen coating thickness, dimension test, impressing test and so on. Especially, we have the most advanced X-ray detector to test wall thickness of each pipe precisely so that we could ensure pipes quality conform to ISO2531 standard.

External zinc spraying (≥130g/㎡) and bitumen coating (≥70um) conform to ISO8179 standard. Epoxy, polyurethane and polye the thylene can be supplied according to clients’ requirments.

Internal cement mortor lining conforms to ISO4179 standard and the cement mortor is firm, dense, smooth and strong adhension. High-Aluminum cement, Portland cement, Sulphate-Resistance cement, epoxy resin, epoxy ceramic for inside lining.
