The Qingdao Huashida steel elbow 3PE anti-corrosion production line is mainly used in various fields, such as industrial oil and gas transportation, water supply transportation, sewage transportation, and chemical transportation.
At least sixteen sets of Elbow pipe conveying structures have been set up, with Elbow pipes placed on the conveying structures. The rotating shaft of the driving mechanism is driven by a rotating motor to rotate the gear plate, and the rotational power is transmitted through the driving mechanism as the center. Adjust the height of the hanging rubber roller using the lifting device of the Elbow pipe conveying structure to adapt to the uniform center height of different pipe diameters.
1. Variable bend pipe conveyor line
Breaking through the overall framework of conventional conveyor lines, a "variable elbow pipe conveyor line" with a fixed anti-corrosion center for bent pipes has been designed, allowing pipes with different elbow pipe diameters, curvature radii, and angles to undergo anti-corrosion operations on the same production line.
2. Precise arc determination technology
Developed precise arc determination technology, using alloy expansion heads to enlarge the diameter of steel pipes and eliminate internal stress during heating deformation. Subsequently, rapid cooling and tempering treatment were carried out to obtain precise curved pipes, overcoming the problem that existing CNC equipment cannot accurately handle springback, elongation, and forming radius.
3. Coaxial winding device for curved pipes
A coaxial winding device for curved pipelines has been designed, which adopts the asynchronous principle of inner and outer shafts and the internal expansion and contraction diameter technology to solve the problem of winding with different diameters rotating at the same line speed, achieving continuous and precise automatic winding.
4. Spray coating technology
Developed Elbow pipe external high-voltage electrostatic spraying technology to achieve automatic electrostatic spraying processing. Effectively improve the uniformity of surface spraying on steel pipes. The surface coating is thin, uniform, and has good glossiness. At the same time, the coating has good adhesion, high hardness, and good corrosion resistance.
5. Sulfide boiling technology
Applied fluidized boiling technology to achieve automatic control of FBE powder heating and melting. Easy to operate, low energy consumption, and stable physical performance.

On March 21, Qingdao Huashida 3PE Steel Pipe Anti-corrosion Machine Line include Steel Elbow 3LPE Coating Machinery were loaded from the factory area, and three trucks were gradually dispatched to Kazakhstan. This is another export of Qingdao Huashida to Kazakhstan. After receiving the order at the end of last year, the company immediately organized a project kickoff meeting. Sort out the equipment list in detail, develop specific production plans, and purchase raw materials from the procurement department. During the production process, the project team held several promotion meetings, strictly following the process standards and increasing inspection efforts. At the beginning of this year, Huashida was busy preparing for production and manufacturing, completing the project before the specified deadline and delivering the goods on time.
