Improve the anticorrosive performance of 3PE anticorrosive steel pipe
The steel industry will continue to promote green, low-carbon and ultra-low emission transformation, and take active actions in carbon emission management, energy structure adjustment, hydrogen metallurgy application and other aspects to promote the green and low-carbon transformation of China's steel industry. China's massive steel industry underpins global manufacturing operations, real estate and infrastructure
Methods for maintaining the thickness of 3PE anticorrosive layer
Improve the accuracy of steel pipe type specifications, smooth the profile and reduce the profile condition. In addition, enhance the control of the profile height to ensure the smooth transition of the profile, and grind the profile when necessary to reduce the profile height.
In the welding pipe shaping level, improve the positioning accuracy of shaping rollers, maintain the easy operation of each shaping roller, different roller surface parallelism is the same
Add groove Angle to welding layer; A set of vertical roller is added in front of the guide plate on the steel plate transport surface. These measures can improve the stability of shaping and transportation, make the profile smoother, and reduce the profile condition, reduce the welding pipe model specification error. In addition, in order to further reduce the height of the cut, the whole cut grinding equipment is added, which plays a good role.
To improve the fine condition of the transmission line, that is, to improve the operation stability of the transmission line and reduce the uneven thickness of the anti-corrosion layer caused by the fluctuation of the steel pipe; In addition, the intelligent condition is improved to ensure the unity of bolt spacing, lap and other performance parameters.
On the basis of ensuring the compactness of the roll, the roller with lower hardness should be selected as far as possible to maintain the stable pressure of the roller. In order to maintain the stability of the pressure of the roller, a small pot is added to the roller to further reduce the influence of other gas equipment on the pressure of the roller.
Enhance water cooling. In order to make the anticorrosive layer into the water quickly hardening, reduce the roller friction caused by the uneven thickness of the anticorrosive layer, especially for large diameter thick wall steel pipe, heat loss is slow
In addition to ensuring the cooling water for the outer surface of the anti-corrosion pipe, the internal cooling system of the anti-corrosion pipe is added, which can help the outer surface cooling water quickly reduce the temperature of the anti-corrosion layer, effectively improve the hardening speed of the anti-corrosion layer, and reduce the uneven thickness of the anti-corrosion layer.
Improve the anticorrosive performance of 3PE anticorrosive steel pipe
There are many factors affecting the anticorrosive performance of 3PE anticorrosive layer, such as the layout of each process, equipment selection, external quality and heating mode, coating temperature, cooling mode, transmission accuracy, material properties and detection
Poor production will lead to small adhesive coating, too thin, cracking or bubbles and other disadvantages. It is very important to implement standards and scientific operating facilities to control the disadvantages and ensure the product rate of anticorrosive steel pipe.
