Product Description: The product is used in the manufacture of water-cooled walls of power plant boilers, which can effectively eliminate the steam film on the inner wall of the steel pipe and improve the thermal efficiency of the furnace wall. The product is manufactured by cold drawing, so that the inner wall of the steel pipe forms inner wall spiral ribs with special geometric dimensions. The finished product is heat treated with protective gas, so that the steel pipe has stable performance and good surface quality. Products can be ordered according to user design requirements.
