Description:
Qingdao Huashida Machinery Co., LTD. Steel elbow 3PE anticorrosive production line, mainly used in the manufacture and processing of oil and gas transportation, water supply transportation, sewage transportation, chemical transportation for 3PE anticorrosive bend (arc pipeline).
At least 16 groups of bending pipe conveying structure are arranged, the bending pipe is placed on the bending pipe conveying structure, the rotating shaft of the driving mechanism is driven by the rotating motor, and the rotating power is driven by the driving mechanism as the center. The center height of different pipe diameters is unified by the lifting device of the bending pipe conveying structure to adjust the height of the hanging roller.

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.

Application:
When the bending pipe passes through the winding mechanism on the outer wall of the bending pipe, the motor drive device provides rotating power for the winding device. During the rotating process, the tape released by the tape release roller is wound, and the belt support device provides lifting support for the long distance tape release without landing. The winding tape is wound outside the tape storage ring, and the tape release is carried out inside the tape storage ring. In order to adapt to the bending of different pipe diameters and different curvature radii, a pipe diameter adjusting mechanism is set up to adapt to the change of bending pipe.
When the anticorrosive bend passes through the cooling mechanism, the spray pump provides water for the spray pipe, slowly flows to the surface of the bend pipe, cools the bend pipe through heat exchange, and the outflow water is imported by the spray tray into the pool for recycling, and finally completes the work of the entire production line.

advantage

(1) Break the overall frame of the conventional transmission line, and design the "variable bending pipe transmission line" with a fixed bending pipe anticorrosion center, so that the bending pipe with different bending diameters, different curvature radii and different angles can be anticorrosive in the same production line.
(2) The development of accurate arc technology, the use of alloy flameout push head to expand the diameter of the steel pipe, eliminate the internal stress during heating deformation, and then rapid cooling and tempering treatment, so as to obtain an accurate arc pipe, overcoming the existing CNC equipment can not accurately deal with the problem of rebound, elongation and forming radius.
