Maintenance of high-frequency welded pipe mill

In terms of production efficiency and economic benefits, high-frequency welded pipe mill production has the characteristics of no pollution, low noise, and does not produce wastewater or exhaust gas. Circulating water cooling is used in production, which is both energy-saving and environmentally friendly, and also saves labor. A single shift only requires 5-8 people.

In terms of usage, with the improvement of weld quality and non-destructive testing reliability of welded pipes, the use of welded pipes has become increasingly widespread, replacing seamless steel pipes in more departments and applications. The growth rate of welded pipes is faster than that of seamless pipes, which is the overall trend of development.

The high-frequency welding process has advantages in many aspects, and has a wide adaptability to the material of the pipe blank and the size of the steel pipe. High frequency welding not only improves the welding speed, but also can obtain welds with small heat affected zones and good penetration.

In terms of quality, the high-frequency welded pipe mill has advantages such as good weld quality, small internal and external burrs, high welding speed, and low power consumption, which can be widely applied and promoted.

The high-frequency welded pipe mill can not only produce irregular pipes, but also produce square and rectangular pipes. Due to the large cross-sectional modulus of square and rectangular pipes, they can withstand greater bending forces, save a lot of metal, processing time, and reduce component weight. Therefore, they are widely used in various fields of industry and agriculture. At the same time, we also need to use and maintain the equipment correctly to extend its service life.

  • 1. During the use process, we must strictly follow the operating procedures in the user manual, let alone allow the machine to operate and use under overload. Before the mechanical operation, we must check whether all parts of the machine can work properly and if there are any faults. Only when all parts and indicators of the machine are normal can we start up and operate and put into production, Otherwise, it will cause mechanical damage.
  • 2. After inspecting the various components of the high-frequency welded pipe mill, we can start up and run it again. During the mechanical production process, we must ensure the stability of the mechanical temperature and production conditions. If there is a mechanical malfunction, we must promptly stop production and check what component of the machine is malfunctioning to avoid causing greater losses. The main faults include unstable mechanical operation, wear of machine components, and whether there are abnormal noises during operation. If any problems occur, they should be promptly inspected.
  • After using the machine for a period of time, we should pay attention to regularly lubricating and cleaning the machine to ensure its cleanliness. Only in this way can the machine operate normally and be relatively lightweight during use. For parts that have already aged in the machine, it is necessary to replace them in a timely manner to ensure that the machine can operate normally at any time. In addition, when the machine is not in use, it is also important to keep the high-frequency welded pipe unit well and not discard it arbitrarily.
