  • Significance of proximity effect to the production of high frequency welded pipe machine
    In addition to the skin effect, the proximity effect is another characteristic of the current during the operation of the high frequency welded pipe machine. When two adjacent conductors pass alternating current of equal magnitude and opposite direction, the current will flow on the inner surface layer adjacent to the two conductors. The outer surface layer of the conductor flows through. The proximity effect of the current makes the current in the conductor further uneven, and it is this unevenness that makes high-frequency welding.

    Common used welded pipe machine sizing section welded pipe quality defects
    The common quality defects of welded pipe in the sizing section of used welded pipe machine can be divided into three categories: dimensional tolerance defects, surface defects and straightness defects. According to these three types of common sizing section welded pipe quality defects are described in detail.

    Adjust the forming method of the thin-walled tube of the used roll forming machine
    The thin-walled tube forming adjustment of the used roll forming machine should not be limited to the forming machine, but must have an overall view and a global view. Here, a concept of generalized forming adjustment is proposed. That is, the forming adjustment is not only the adjustment of the forming machine, but also involves the welding machine, the sizing machine, the material storage (looper), the raw material, etc., which are closely related to the forming quality of the thin-walled tube.

    Principles of strengthening and weakening of high-frequency current proximity effect and skin effect of used welded pipe equipments
    The proximity effect and the skin effect of high-frequency current are twin brothers. They act on the welded pipe blank at the same time, and their functions should be treated differently according to the actual production of used welded pipe equipments. The principle is to make appropriate trade-offs (strengthening and weakening) for the main contradiction, each with its own emphasis. For example, when welding thin-walled tubes, it is necessary to appropriately weaken the proximity effect while strengthening the skin effect, that is, to appropriately increase the opening angle to prevent "overburning" during the welding process.

    Explain the characteristics of the welding pipe sizing process of high frequency welded pipe equipment
    The welding pipe sizing process of high frequency welded pipe equipment includes empty rolling, micro-tension rolling, active rolling and passive rolling, the maximum rolling force and the maximum linear speed are not the same point, the small hole type accepts large pipes and traces. 6 features such as reducing rolling.

    Understand the basic functions of high frequency welded pipe equipment welded pipe sizing
    The welded pipe sizing of high frequency welded pipe equipment refers to rolling the welded pipe through a specific pass roll, and adjusting the round or special-shaped pipe with irregular size and shape to one with regular shape and size that meets the requirements of the standard. Finished tube.

    Four categories of welded pipe blanks for high frequency welded pipe equipment (3)
    Welded pipe blank is the raw material of high frequency welded pipe equipment to make welded pipe. Its mechanical properties and chemical composition have a profound impact on the quality of welded pipe, and its width is the first factor that determines the strength of the weld. We usually say that the width of the welded pipe blank is suitable, which refers to the width of the given thickness; the determination of the width is restricted by many factors.

    Prerequisites for Straightening Welded Pipes by high frequency welded pipe equipment
    If the welded pipe is not straight, first check the high frequency welded pipe equipment to see if the problem lies in the sizing. Because it is a very important point to affect the straightness of the welded pipe.

    Thin wall tube forming with used roll forming machine
    The difference between the thin-walled welded pipe and the thick-walled pipe forming difficulty of the used roll forming machine is that the difficulty of thin-walled pipe forming is that the edges of the tube blank have too much longitudinal extension during the forming process, which is easy to produce forming bulges.
