High Frequency Welded Finned Tube ASTM A335 P22 For Industrial Economizers
ASTM A335 Specification for seamless ferritic alloy steel pipe for high temperture service.
High-frequency welded spiral finned tubes are formed by welding the base tube and the rotating strip-shaped fins on the tube surface using the high-frequency welding process. The weldable materials include carbon steel, low-carbon steel and stainless steel.
The application scope of alloy steel HFW finned tubes covers power plants, oil refineries, waste incineration plants and heavy industries, making it the preferred choice for energy-saving heat recovery systems.
