Compared with seamless pipes, high frequency welded pipes are characterized by high continuity, high efficiency and low cost. At the same time, the production of raw material strip is developing rapidly, and the proportion of welded pipes in the whole pipe is increasing. The production of high frequency welded pipe mill line has the characteristics of no pollution and low noise, and does not produce waste water and waste gas. Circulating water cooling is used in production, which is energy-saving, environmental protection and labor-saving. Only 5-8 people are needed for one shift. In application, with the improvement of weld quality and non-destructive testing reliability of welded pipe, the use of welded pipe is more and more widely. It replaces seamless pipe in more fields and uses. High frequency welding can not only improve the welding speed, but also obtain small heat affected zone and good burn-through weld.
In terms of quality, the high frequency welded pipe mill line has the advantages of good weld quality, small internal and external burrs, high welding speed and low power consumption, which can be widely used and promoted. High-frequency welded pipe unit can normally produce round pipes, while also square and rectangular pipes are produced. Because square and rectangular pipes have large section modulus, can withstand greater bending force, can save a lot of metal, save processing time and reduce the weight of components, etc., so they are widely used in industry and agriculture area.
For the maintenance of high frequency welded pipe mill line, we should learn three points as below.
First of all, in the process of use, we must strictly operate according to the operating procedures in the instruction manual, not to overload and operate the machine. And we have to check the machinery before complaining about production or mechanical operation. Whether the parts can work normally, whether there is any fault, only when the various parts and indicators of the machine are normal, the machine can be started up and put into production, otherwise it will cause mechanical loss.
Secondly, after checking all parts of the high pipe mill line, we should start running again. In the process of production, we should ensure the stability of the temperature and production condition of the mill line equipment. If the equipment fails, we must stop production and check which part of the mill line is out of order to avoid causing greater losses. The main faults include the unstable operation of mill line, the grinding of equipment, and whether there are abnormal noises in the operation process. If there are any problems, they should be checked in time.
Thirdly, after the mill line has been used for a period of time, we should pay attention to the regular lubrication and cleaning of the mill line to ensure its cleanliness. Only in this way can the machine run normally and be more portable in its production. For the aging parts of the mill line, we must replace them in time to ensure that the whole line can run normally at any time.
