Studded Fin Tube ASME SA335 P5 13Cr (SS 410) Pin Tube for Steam Reforming Furnace
YUHONG GROUP's studded tube is mainly used in the petrochemical and coal chemical industry for tubular heating furnace, convection heat exchanger, air preheater, chemical equipment, heat exchange equipment. The studded tube is mainly used in the petrochemical and coal chemical industry for tube heating furnaces, convection heat exchangers, air preheaters, chemical equipment and heat exchange equipment. To expand the heat transfer area of the light tube by 2 to 3 times, it can improve the heat transfer coefficient on the flue gas side, improve the comprehensive thermal efficiency of the equipment and is an energy-saving heat transfer element. Its main function is to expand the heat transfer area of the tube and improve the thermal efficiency of the heating furnace.
