Application and processing requirements of nailing head tube
一,ApplicationThe heat transfer coefficient of the flue gas side can be improved by using the nil-head tube in the convection chamber of the heating furnace in petrochemical industry. The area of the nil-head tube is 2 ~ 3 times that of the light tube. The same heat intensity can be obtained by using the nil-head tube under the condition of reasonable design
二,Manufacturing.
The welding of tube finning process is controlled by PLC program. The feeding motor and indexing are brake motor. The man-machine interface can set the number of nail heads, indexing parameters and compensation coefficient
三, technical characteristics1, nail head specifications can be adjusted according to user needs;2. The height of the welding flesh bulge at the root of the welding nail head is about 1mm (to meet the requirements of nodular welding);3, high welding efficiency, can weld 30 nail heads per minute;4. Welding power is 160kVA; The power grid voltage is single-phase 380V.Market and economic benefit forecastNailhead tube is the main component of chemical equipment and heat exchange equipment. The production of the above equipment or equipment maintenance need to nail head pipe. Nodule - free welding is an advanced and stable technology in nay-head pipe manufacturing, which has a good prospect of effective use.
