What is the relationship between continuous cast iron pipe and ductile iron pipe?
Continuous cast iron pipes are usually grey cast iron pipes. Its tensile strength and elongation are much lower than those of nodular cast iron. In chemical composition, grey cast iron has less carbon content than nodular cast iron. According to the organization, the graphite form of gray iron is flaky, and the graphite form in spheroidal graphite cast iron is spherical.
In general, the continuous cast iron pipe is the continuous casting of gray cast iron pipe, while the centrifugal cast iron pipe is centrifugal ductile iron pipe. Of course, you have to be hard, just to make continuous ductile iron pipes, that's what you want.
Cast iron pipes are divided into continuous cast iron pipes and centrifugal cast iron pipes according to different casting methods. They are divided into gray cast iron pipes and ductile iron pipes according to different materials.
