    Medium frequency induction heating in pipeline anti-corrosion coating production line

    Ф 108 —Ф 630 steel pipe 3PE anti-corrosion production line

    3PE anti-corrosion heating equipment.

    1, the project content:

    Ф108—Ф630 steel pipe 3PE anti-corrosion production line

    2, the design basis:

    Steel pipe diameter: Ф108—Ф630

    Steel pipe length: 8000mm-12000mm

    Process speed: 1200mm/min-4000mm/min

    3, the pipeline conveyor

    According to the user's requirements, our company Ф108—Ф630 steel pipe 3PE pipeline anti-corrosion, pipeline anti-corrosion production line is designed as the transmission line connecting the drive shaft, so that the pipeline running speed is stable and convenient to adjust the pitch of the large and small pipes. The base of the conveyor is welded by national standard 18# channel steel, 18# square steel and 12mm thick steel plate. The specifications of this line conveyor are 1600mm × 5000mm × 12 (three sets of tires per rack). 1600mm × 800mm × 5, (one of which is equipped with a high temperature wheel and one is equipped with power). The transmission wheel model is a 600-9 pneumatic tire (stronger than the solid wheel, the pipeline runs smoothly), and the power is controlled by frequency conversion. The base of the transmission wheel is fixed on the adjusting track with the same hole spacing to facilitate the adjustment of the spacing between the large and small pipes; the width adjustment adopts the screw adjustment, which improves the pipeline conveying precision and reduces the labor intensity.

    4, the descaling machine:

    This machine is based on the introduction of advanced technology from the United States and Italy, using a modern computer simulation technology, developed a new type of steel pipe outer wall shot blasting equipment, which can remove the rust and scale on the surface of the steel pipe, completely before the outer wall of the steel pipe is painted. The cleaning requirements can meet the needs of cleaning the outer wall of small and medium-sized engineering steel pipes.

    5, medium frequency heating:

    This production line is equipped with 2 50KW and 50 0KW total two intermediate frequency heating equipment. 25 0KW is used for removing the surface moisture of the steel pipe before the descaling machine to improve the descaling effect. 5 00 KW is used for external epoxy powder spray heating. The control part adopts a specially designed control circuit with overvoltage, overcurrent, voltage limiting/current limiting, phase loss, undervoltage, under water pressure and other protections. The control line dedicated integrated box is completely isolated from the high pressure area to keep the control room clean and cool. Greatly improve control board life and system reliability. It is preferred to have high-power converter devices from well-known domestic manufacturers.

    6, dusting system:

     8 gun control center. DK type 1 set

    The above device contains 8 automatic spray guns, the spray gun is built-in high pressure, and the control cabinet controls the voltage, current and pneumatic system of 8 automatic spray guns. And control 8 venturi powder pump powder supply system.

    The above device comprises a set of fluidized bed powder supply system. The size of the fluidized bed: (L×W×H) 800×775×570 (mm) contains 8 venturi powder pumps.

    7, extrusion machine

    This production line shall be equipped with one SJF1 5 0/30 and one SJF 6 5/ 28 anti-corrosion extruder.

    8, water cooling room:

    It is closed with plastic steel and is beautiful and easy to observe. All are made into a movable window for easy access. The pump uses a flow rate of 100 cubic meters per hour (one standby). The cooling water pipe regulating valve is installed on the side of the operation cabinet for easy adjustment.

    9, air compressor and pipe mechanism:

    The production line is equipped with a 6-cubic screw air compressor, a 6-cubic air dryer, and a 1-cubic gas storage tank for the powder spraying equipment. However, the gas volume is sufficient, so the cylinder of the pipe-cutting system is changed to a cylinder. It saves the investment in hydraulic stations and hydraulic oil and the cost of changing hydraulic oil every year. Maintenance is also clean and convenient. A total of 8 forks and cylinders and 2 lift cylinders are required.

    10, breaking machine, lift and secondary descaling machine:

    The breaking machine adopts a wire wheel breaking machine, and the set device is equipped with a walking wheel to be movable. Moreover, the dust recovery device is equipped to effectively solve environmental problems.

    The lift adopts the cylinder lifting, and the transmission wheel adopts the single- wheel lifting power transmission at both ends to ensure the processing needs.  

    The secondary descaling adopts the wire wheel derusting and compressed air purging to ensure the cleanliness of the outer wall of the steel pipe meets the requirements and improve the adhesion of the epoxy powder.

    11, the release platform

    The upper tube, the lower tube and the transition platform are all welded with 18# GB-shaped I-beam, which ensures the robustness of the platform. The three platforms have a total length of 30 meters.

    12, manufacturing and installation schedule

    The production period is 40 days from the effective date of the contract, and the installation period is 20 days (the installation conditions are available).
