ASTM A213 Base Tube T9 11Cr Studded Fin Studded Finned Tube For Steam Reforming Furnace
TONG CHUANG GROUP's studded tubes are pivotal in the petrochemical and coal chemical industry for various applications such as tubular heating furnaces， convection heat exchangers， air preheaters， chemical equipment， and heat exchange equipment. The primary function of these tubes is to amplify the heat transfer area of the tube， thereby enhancing the thermal efficiency of the heating furnace.
Moreover， TONG CHUANG GROUP's ASME SA213 T9 / ASTM A213 T9 material， a high temperature chromium-molybdenum alloy heat-resistant steel， complies with U.S. standards. This steel is widely utilized in petroleum refining devices due to its exceptional attributes like oxidation resistance， high temperature strength， and resistance to sulfide corrosion. It is specifically beneficial for high temperature and pressure， flammable， and explosive pipelines， particularly in direct heat pipes of heating furnaces where medium temperatures can reach up to 550-600°C.
Studded tubes play a crucial role in fire furnaces by augmenting heat transfer efficiency and enhancing overall furnace performance. The studs induce turbulence in the flue gas flow， boosting heat transfer rates and subsequently leading to improved thermal efficiency and reduced fuel consumption.
