Flexible cast iron pipe

The base structure of cast iron has small potential difference, small electrochemical action, and high silicon content, which can form a continuous SIO2 protective film on the surface. Therefore, its rust resistance is much higher than that of steel, and it is resistant to cast iron in the same environment and medium. The rust is more than three times that of steel. The continuous gray cast iron pipe has a nominal diameter of 75 to 1200 mm. The straight pipe length is 4 meters, 5 meters and 6 meters; according to the wall thickness, it is divided into three levels: LA, A and B. The sand-type centrifugal gray cast iron pipe has a nominal diameter of 200-1000 mm, and the effective length is 5 meters and 6 meters. According to the wall thickness, it is divided into two grades, P and G. High strength, good toughness, thin wall, low metal consumption, and high pressure.
