Studded Tubes are applied to convection chamber of heating furnace in petrochemical industry for increasing the heat transfer coefficient at the fuming side. Studded Tubes are two or three times the square of light Tubes and because of the usage of studded Tubes， the hot strength can be got as the same as radiation in the reasonable design.
