Ductile iron pipe EN545 EN598 ductile iron pipe ISO2531 centrifugal ductile iron pipe

Nodular cast iron pipe refers to a pipe made by high-speed centrifugal casting of a centrifugal nodular cast iron machine after adding spheroidizing agent to cast molten iron above No. 18, referred to as nodular pipe, nodular iron pipe and nodular cast pipe, etc. It is mainly used for the transportation of tap water and is an ideal choice for tap water pipelines. According to the different uses of customers, we can coat various customer-satisfied materials as required:

Cement mortar lining + special coating: This kind of internal anti-corrosion measure is suitable for pipelines conveying sewage and can improve the corrosion resistance of the lining.

Epoxy coal tar pitch coating: Epoxy coal tar pitch coating is suitable for both gas pipelines and sewage pipelines. It is a two-component coating that has high adhesion and a very smooth surface

Epoxy ceramic lining: Epoxy ceramic lining is suitable for sewage pipes and gas pipelines, but due to the difficult manufacturing process and high cost, it has certain limitations in use. Epoxy ceramic lining has high adhesion and smoothness, and is a good anti-corrosion coating.

Aluminate cement coating or sulfate cement coating: Both of these special cement coatings are suitable for the internal anti-corrosion of ductile iron pipes used in sewage pipelines to improve the corrosion resistance of acid and alkali components in sewage.

Polyurethane coating: It is a new type of green special coating developed to meet the needs of environmental protection. It has good wear resistance and corrosion resistance.
