Advantage
1.High temperature resistance and corrosion resistance
2.Firm fin combination and high reliability.
3.Enhanced heat transfer efficiency
4.Strong resistance to abrasion and coking.
5.Long service life, low maintenance requirements
The nail head tube is also called nail like ribbed tube, In petrochemical industry, nail head pipe is widely used, Especially in the convection chamber of the tubular furnace, in order to enhance the heat transfer effect outside the tube, the heat transfer element often adopts the nail head tube.
