Ductile iron - Import export

Ductile cast iron pipe is a pipe type preferred in main transmission lines since it has superior properties such as corrosion strength and abrasion resistance as it is made of cast iron, as well as being able to stretch without deformation. In regions where the temperature is low, freezing frequently occurs on the main transmission lines, especially in winter. Such problems can be avoided by using pre-insulated ductile iron pipes.
