Steel pipe conveyor system

How does 3PE pipe bending anticorrosive production line remove rust from the outside of the steel pipe? The steel pipe body comes online from the upper pipe platform, the outer wall of the steel pipe is removed by shot blasting and rust removal machine, the finished steel pipe enters the inner shot blasting machine, and the finished internal rust removal steel pipe enters the inner ring production line for epoxy powder coating on the outer surface, when the pipe bends through the ring powder chamber, Spray powder outside the pipe by powder spray gun, and effectively shield the powder floating around, and recycle the powder through the recovery device.

Intelligent control system
1. First of all, in the mechanical AI car, the mechanical AI car is designed to sense the position of the steel pipe through the sensor, communicate with the modern industrial PLC through the chip to calculate the moving track, the steel pipe can be raised 100 mm from the bench surface, and the steel pipe can be accurately moved to the designated station through the transmission of the rack and pinion, which solves the problem of the steel pipe moving.
2. Secondly, in the coating thickness digital control device, a microcomputer digital controller controlled by a single chip computer is developed to accurately control the coating thickness. It can automatically store and call technical parameters such as powder quantity, physical and chemical quantity, electrostatic voltage, electrostatic current, etc., which solves the problem of weighing the powder quantity and changing the machine during each production of the existing knob-type spraying controller.
3. In the C-type intermediate frequency heating technology, the design of intermediate frequency voltage is 660V50HZ, 12 pulse power supply, from the high voltage line through the special transformer to provide power to the intermediate frequency, in order to achieve the purpose of rapid heating, to solve the ordinary 380V50HZ power can not meet the heating speed requirements of large steel pipe.

Technological processes:
Upload pipes→pipes screw conveyor→rust removal of intermediate frequency heating→Epoxy powder coating→outer layer soli quid & polyethylene coating→cooling spray→pipes screw conveyor→grinding pipes, send→unload pipes

1. Achieved breakthroughs in core technologies such as internal and external epoxy synchronous coating, small volume and high bearing transfer wheel, high-speed internal shot blasting and rust removal of small tubes, special transfer equipment and spraying process for ultra-large tubes, and digital coating control, solving the common problems of domestic epoxy resin spraying equipment, such as secondary heating, two-step processing, anti-rotating impact and poor bearing capacity, etc.
2. The product performance reaches the domestic leading level, compared with similar products, the use of advanced internal and external synchronous technology and small volume high bearing structure, to achieve the processing specification range, processing speed, spraying effect, equipment layout of the more perfect balance.
3. Compared with the existing two-step production line, it can greatly reduce energy consumption, shorten spraying time by nearly 50%, and the carrying capacity of a single transfer wheel can reach 3 times.
4. It can be applied to the rapid anti-corrosion processing of super-large steel pipes with diameter of 3200mm, length of 12 meters and weight of 30 tons under the premise of saving equipment space.
5. It provides a highly intelligent overall solution for the rapid and accurate spraying of super-large steel pipes, which elevates China's epoxy resin spraying anti-corrosion technology to a new level and plays a leading and demonstration role in the industry.
