Studded tube is also called nail head tube. In the fields of petroleum refining and chemical industry, coal chemical industry, metallurgy, ceramics, building materials, etc., stud tubes are widely used. Especially in the convection chamber of the tube heating furnace, in order to enhance the heat exchange effect outside the tube, the heat transfer element often uses a nail-head tube. The area of the studded tube is 2 to 3 times that of the light tube, which can improve the heat transfer coefficient on the flue gas side.https://www.glorytubetech.com/product/stud-tube/
