The maintenance of cold drawn welded pipe requires regular maintenance according to the corresponding maintenance standards. Even if the working condition is good, it is necessary to carry out all-round maintenance on the welded pipe unit to fundamentally avoid mechanical failure and ensure smooth production.
In the process of maintaining cold drawn welded pipes, parts that are found to be severely worn should be replaced as soon as possible. Regular maintenance and protection of machinery by professional protection personnel, such as adding lubricating oil, etc. Then apply high-quality anti-rust oil on the sliding side to prevent the equipment from oxidizing and rusting, especially when it is idle for a long time. Doing a good job in the maintenance of details is very good for the normal work of cold drawn welded pipes, and it can also ensure the smooth progress of production.
In the daily maintenance work, the important point is to be careful, whether it is about the overall work of the cold drawn welded pipe, or about the replacement of various parts, regularly check the wear and tear of the parts, especially when the workload is heavy, pay more attention to these Parts, in case wear seriously affects the production process.
1. In terms of economic benefits, the noise of cold-drawn welded pipe is small; the use of circulating water cooling system is environmentally friendly and energy-saving.
2. In terms of use, welded pipes are used more and more widely and are suitable for agricultural and industrial production.
3. In terms of quality, the welded pipe products of cold-drawn welded pipes are good, the welds are intact, there are not many burrs, the speed is fast, energy saving and cost saving.
4. Because the high-frequency welded pipe has the advantages of good weld quality, small internal and external burrs, high welding speed, and low power consumption, it has been widely used and promoted.
5. On the welded pipe unit, it is generally possible to produce heterosexual pipes, and more square and rectangular pipes are produced. Because square and rectangular pipes have a large section modulus, cold-drawn welded pipes can withstand greater bending force, which can save a lot of metal, It has the advantages of saving processing time and reducing the weight of components, so it is increasingly popularized and used in various aspects of industry and agriculture.
There are many processes in the process of welded pipe processing, and every detail needs our attention. Welded pipes need to undergo various processes before use. The heat treatment of welded steel pipe is an important link in the process of welded steel pipe. Thermal processing is a metal thermal processing process that heats, heats, and cools metal materials in a certain medium, and controls the properties of metals by changing the metallographic structure of the surface or interior of the material.
During the heating and cooling process of the structural welded pipe workpiece, due to the inconsistent cooling speed and time of the surface layer and the core layer, a temperature difference will be formed, resulting in uneven volume expansion and contraction, and stress, that is, thermal stress. Under the action of thermal stress, the initial temperature of the surface layer is lower than that of the core layer, and the shrinkage is greater than that of the core layer, so that the core layer is stretched. When the cooling is finished, the skin is compressed and the core is stretched, because the cooling volume reduction of the core cannot proceed freely.
