A single layer of epoxy powder coating Ф108 -Ф1016 pipe coating line

1, the project content:

Ф108 -Ф1016 steel single layer of epoxy powder coating Coating Production Line

2, the design basis:

Steel pipe diameter: Ф 108 —Ф1016

        Steel pipe length: 8000mm-12000mm

Process speed: 1200mm/min - 5000mm/min

3, the pipeline conveyor

According to user requirements, our single layer of epoxy powder coating Ф108 -Ф1016 pipe coating line is designed as a transmission line in a single round of the power unit, so that the speed of the pipeline operation more smoothly and easily adjust the size of the pitch tube. The reducer adopts WPA type, and the power is 7.5 KW inverter motor, a total of 6 sets. The power control adopts centralized control, the control cabinet is a piano cabinet, and the frequency converter is concentrated in four control cabinets. The frequency converter adopts domestic famous brands. The base of the conveyor is welded with GB 20# channel steel, 20# rectangular steel and 14mm thick steel plate. The specification of this production line conveyor is 2000mm × 6000mm × 13 (four sets of tires per rack). 2000mm × 800mm × 10, (including eight sets of tires, one assembled high-temperature wheel, and two single-frame each set of two sets of tires). The transfer wheel is a 600-9 pneumatic tire (stronger than the solid wheel, the pipe runs smoothly). The base of the transmission wheel is fixed on the adjusting rail with the same hole spacing by 4 screws to facilitate the adjustment of the size of the pipe. The angle adjustment adopts the screw adjustment, which improves the pipeline transmission accuracy and reduces the labor intensity. The total length is 90 meters.

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 large and medium-sized engineering steel pipes. It has the following advantages:

1. The fifth-generation cantilever centrifugal blasting machine with large shot blasting and high throwing speed has significantly improved the cleaning efficiency and obtained satisfactory cleaning quality. It is a patented product.

2. The equipment has been successfully developed according to the redesign of advanced technology at home and abroad. It has the characteristics of high productivity, convenient operation and small volume, and is the first in China.

5, medium frequency heating:

This production line is equipped with two intermediate frequency heating devices of 500KW and 1000KW. Before using 500KW for descaling machine, remove the surface moisture of the steel pipe, improve the descaling effect, and prevent the steel pellets from agglomerating. 1500KW is used for external epoxy powder coating heating.

5 00kw parameters:

10 00kw parameters:

6, dusting system:

1, 8 gun control center. DK type 2 sets

Each set of the above devices 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.

Each set of the above devices contains a fluidized bed powder supply system. The fluidized bed has the following dimensions: (L×W×H) 800×775×570 (mm) containing 8 venturi powder pumps.

7, water cooling room:

The water cooling room is closed by plastic steel glazing, which is beautiful and easy to observe. There are several activity windows on each side for easy access. The cooling water pump uses a flow rate of three cubic meters per hour (one standby). In addition, two intermediate frequency cooling water pumps have a flow rate of 25 cubic meters per hour. The cooling water pipe regulating valve is installed on the side of the operation cabinet for easy adjustment.

  8, air compressor and pipe mechanism:

The production line is equipped with a 10-cube screw air compressor, a 10-cubic air dryer, and a 1.5-cubic gas storage tank for powder spraying equipment (with 3 filters), but the gas volume is surplus, so the pipe is put The system's cylinders were changed to cylinders, saving 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 are required. (The gas pipeline and gas storage bag are the responsibility of the user)

 9. Pipeline platform

The upper tube, the lower tube and the transition platform are all welded with 20# national standard I-beam, which ensures the robustness of the platform. The total length of the three platforms is 30 meters (the length is determined by the site and made by the user).

  10, manufacture and installation period

The production period is 50 days from the effective date of the contract, and the installation period is 20 days (the installation conditions are available).
