Products Description
T type joint ductile iron pipe (push-in type) is the preferred pipe for municipal water supply project, with the advantages of easy installation, good seismic performance, corrosion resistance and so on. Our T-type joint ductile iron pipe sizes range from DN80mm to DN1800. T-type joint nodular cast iron pipes are laid with flexible socket joints in the engineering site.
Advantages of Ductile Iron Pipe
Better Mechanical Properties .
Ductile Iron Pipe have better Mechanical Properties than Steel Pipe and Grey Iron Pipe
