First, the project content:
Ф 89 —Ф 8 20 steel pipe 3PE pipeline anti-corrosion production line
Second, the design basis:
Steel pipe diameter: Ф 89 —Ф 8 20
Steel pipe length: 8000 mm -12000 mm
Process speed: 1200 mm / min - 5 000 mm / min
Third, 3PE pipeline anti-corrosion Ф 89 —Ф 8 20 steel pipe production line pipe conveyor
According to the user's request, our company's 9 8 9-Ф 8 20 pipeline anti-corrosion production line is connected by transmission shaft to transmit power . The base of the conveyor is welded with the national standard 16 # channel steel, 16 # square steel and 12 2 mm thick steel plate. The specification of this line conveyor is 2000 mm × 6000 mm × 13 (4 sets of tires per rack). 2000 mm × 800 mm × 10 (one of them is equipped with a high temperature wheel). The transmission wheel is a 600-9 weighted pneumatic tire (stronger than the solid wheel, the pipeline runs smoothly), and the power is controlled by frequency conversion.Total length 8 8 meters
Fourth, 3PE pipeline anti-corrosion Ф 89 —Ф 8 20 steel pipe production line descaling machine:
The new steel pipe outer wall shot blasting equipment can remove the rust and scale on the surface of the steel pipe, completely meet the cleaning requirements before the outer wall of the steel pipe is coated, and can meet the cleaning requirements of the outer wall of the large and medium-sized engineering steel pipe.
5, 3PE pipeline anti-corrosion Ф 89 —Ф 8 20 steel pipe production line medium frequency heating:
This production line is equipped with two intermediate frequency heating devices of 35 0K W and 1 0 00KW.

Sixth, dusting system:
1, 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.
Seven, extrusion machine
This production line must be equipped with one SJF 15 0/30 and one SJF 65 /30 anti-corrosion extruder.
Eight, water cooling room:
It is closed with plastic steel and is beautiful and easy to observe. There are several activity windows on each side for easy access. Pump flow rate per hour using 100 cubic two sets (one spare). The cooling water pipe regulating valve is installed on the side of the operation cabinet for easy adjustment and the length is 23 meters.
Nine, air compressor and pipe mechanism:
The production line is equipped with a 9-cubic screw air compressor, a 9-cubic air dryer, and a 1.0- cubic gas storage tank for the powder spraying equipment, but the gas volume is surplus, so the oil cylinder of the pipe system is changed to The cylinder 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.
Ten, 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 double-wheel lifting power transmission at both ends to ensure the processing needs of the thick-walled pipe.
The secondary descaling adopts the wire wheel rust removal and compressed air purging to make the outer wall cleanliness of the steel pipe meet the requirements and improve the adhesion of the epoxy powder.
XI. Pipeline platform
The upper tube, the lower tube and the transition platform are all welded with 20# GB-shaped I-beam, which ensures the robustness of the platform. The total length of the three platforms is 30 meters (made by the user as appropriate) .
Twelve, manufacturing and installation schedule
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).
