Ductile iron pipe
It has high strength & hardnes as steel and better corrosin resistance than steerl and grey iron, DUNHUI ductile iron pipe is the ideal substute for gray cast iron pipe and common steel pipe. In addition, our DI pipes are produced with good straightness, identical wall thickness, high dimension accuracy, smooth surface finished, remarkable mechanical properties and firmly sticking internal & external coating layer as well. Flexible Push-in joint and rubber gasket are used for more convenient installation of pipelines.
“DUNHUI” is your correct choice. Welcome to visit

4.Product Performance of Ductile Iron Pipe
Inner coating - cement lining
Product performance---inner lining anticorrosive
SUNS brand zinc coating ductile iron pipes inside lined by using centrifugal cement mortar protective layer. This protective layer is made of high quality and rigorous testing of cement raw materials, whole process controlled by computer.
Cement lining quality complies with international standards ISO4179, to ensure lining strong, dense, smooth and good surface adhesion to iron surface, no falling, scaling, and thickness uniformity, ensure that the internal every inch pipeline have been protected very well.
