There are significant differences between cast iron pipe and PVC pipe in multiple aspects, mainly reflected in material properties, performance, application areas, and maintenance.

Cast Iron Pipe Material Characteristics

Cast iron pipe: Cast iron pipes are mainly composed of iron and carbon, and are made through casting processes. It has high strength and toughness, and can withstand significant internal water pressure. In addition, cast iron pipe also have good corrosion resistance, especially ductile iron pipes that have undergone special treatment, which have even better corrosion resistance.

PVC pipe: PVC pipe is mainly made of polyvinyl chloride resin as the main raw material, with the addition of appropriate stabilizers, lubricants, fillers, color enhancers, etc. It is extruded by a plastic extruder and injection molded by an injection molding machine. Through cooling, curing, shaping, inspection, packaging and other processes, the production of pipes and fittings is completed. PVC pipes are made of lightweight material, making them easy to transport and install.

The biggest advantages of cast iron pipe are: flame retardant, noise reduction, noise isolation,

The disadvantages of PVC pipe are: loud noise, flammable, poison gas will be generated whill burning.

Cast Iron Pipe Performance  

Cast iron pipe: Cast iron pipes have high compressive and tensile strength, as well as good sealing and corrosion resistance. It can maintain stable performance in complex geological conditions and harsh usage environments.

PVC pipe: PVC pipe also has good tensile and compressive strength, but its flexibility is relatively poor. The inner wall of PVC pipe is smooth, with low fluid resistance and strong water transmission capacity. In addition, PVC pipes also have good corrosion resistance and chemical resistance, which can resist the erosion of various chemicals.

Cast Iron Pipe Application Fields   

Cast iron pipe: Cast iron pipes are widely used in urban water supply, drainage, gas transportation and other fields. Especially in water supply systems, ductile iron pipes have become the preferred material due to their excellent performance.

PVC pipes: PVC pipes are more commonly used in water supply and drainage systems, agricultural irrigation, industrial fluid transportation, and other fields. Its price is relatively low, and it is easy to process and install, so it has a high cost-effectiveness in many situations.

Cast Iron Pipe Maintenance   

Cast iron pipe: The maintenance of cast iron pipe is same easy with PVC pipe.

PVC pipe: The maintenance of PVC pipe is relatively simple, mainly focusing on the cleaning and dredging of the pipeline. Due to its lighter material, transportation and installation processes are also more convenient.

In summary, there are significant differences between cast iron pipe and PVC pipes in terms of material properties, performance, application areas, and maintenance. When selecting pipes, comprehensive consideration should be given to the specific usage environment and requirements.
