Commissioning of welded pipe unit and matters needing attention in daily maintenance
Welded pipe unit can be so widely used with its own advantages are inseparable. The development of the welded pipe unit industry is so rapid, in order to remain invincible, it is necessary to improve the production quality of the welded pipe unit, and do a good job in the debugging and daily maintenance of the welded pipe unit. Then the daily maintenance and commissioning of welded pipe unit should pay attention to what?

Welded pipe unit investment market information source limitations
Compared with the investment promotion of welded pipe units, it is especially important to master the information of market changes. However, looking at the current welded pipe unit market, many welded pipe unit investment promotion information is limited and there is no relevant channel to provide information to dealers, especially the industry information related to the current business. As the daily business has to run by itself, the time to read books and newspapers is less, and even less information is obtained through the Internet.

What is the production process of the straight seam welded pipe unit?
Longitudinal welded pipe machine has the advantages of simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank, and can also produce welded pipe with different pipe diameter with blank of the same width. However, compared with the same length of the straight seam pipe, the length of the weld is increased by 30 to 100, and the production speed is low.

Selection of raw material width of high frequency welded pipe strip
The correct selection of strip width is of great significance to the dimensional accuracy and weld quality of the finished pipe. The raw material width of high frequency welding is affected by various factors, such as material, welding current frequency, edge state of strip steel, welding allowance, sizing allowance, etc. Generally, it can be calculated according to the following empirical formula:
