ASTM A355 P9 11CR SERRATED FIN TUBE

ASTM A355 is a standard specification for seamless ferritic alloy-steel pipe for high-temperature service. P9 refers to the grade of steel used in the pipe, which is a low alloy steel with chromium and molybdenum content.

11CR refers to the 11% chromium content in the steel, which provides enhanced corrosion resistance and high-temperature strength.

Serrated fin tube refers to a type of heat exchanger tube that has fins on the outer surface. These fins increase the surface area of the tube, allowing for more efficient heat transfer between the fluid inside the tube and the surrounding environment. The serrated design of the fins helps to improve heat transfer even further.
