ASTM A335 P9 is a grade of seamless ferritic alloy steel pipe for high-temperature service. It is commonly used in power plants, refineries, and other industries where high-temperature and high-pressure conditions are present.
11CR refers to the chromium content in the alloy, which enhances the pipe's resistance to corrosion and oxidation at high temperatures.
Fin-serrated fin tubes are a type of heat exchanger tubes that have 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 enhance turbulence and improve heat transfer.
Overall, ASTM A335 P9 11CR fin-serrated fin tubes are used in heat exchangers and other applications where efficient heat transfer is required in high-temperature environments.
Serrated Finned Tube use high-frequency welding production process, using high-frequency power source as heat source, to heat steel strip and steel pipe at the same time, so that they can be welded together into one
U-bends with longitudinal fins and fin coils are available on request.
Longitudinal fin types: one piece, standard U-bend, cut and twisted, perforated, etc...
The fin channels are welded to the tube in pairs. The fin height, number of fins, and fin thickness can be specified.
Fins can be used for OD pipe or NB pipe.
Serrated Finned Tube is a new, wear-resistant and high-efficiency heat-exchange material. It is a high-efficiency and energy-saving heat-exchange element. It is widely used in waste heat recovery, petrochemical, power station boilers, economizers, passenger cars, industrial and civil building heating and refrigeration. , Medicine drying, wood drying, grain drying systems and other industries.
