Intermediate frequency pipe expanding machine manufacturing

Intermediate frequency pipe expanding machine manufacturing quality problems  

Medium frequency pipe expanding machine mainly produces the quality of large diameter seamless steel pipe, mainly divided into several sizing forms, focusing on the advanced frame and hot pipe expanding machine production of large diameter seamless steel pipe using the sizing process.  On the basis of the characteristics of the production process, the material and quality stability of the product are considered.  

Intermediate frequency pipe expansion machine is mainly processed with hot expansion steel pipe, when customers customize the pipe expansion machine when said hot expansion pipe usually refers to seamless steel pipe, because in some pipe construction using seamless steel pipe rather than welded pipe, hot expansion steel pipe is often a reasonable choice for people who need high quality steel pipe.  Intermediate frequency pipe expansion machine is mainly composed of induction heating steel pipe production process, mainly divided into the following parts: seamless hot expansion steel pipe is mainly raw material is steel, steel is extracted from iron, there may be other materials and steel together.  The process of producing both welded and seamless steel begins when raw steel is cast into a more viable form.  The ingot is then obtained from the molten steel mould.  The ingots are put into a machine, where they are pressed into thinner and longer sheets of steel. The elongation process continues to obtain the required stiffness. The steel is flipped so that the steel is even on both sides. The latter procedure is to cut the uneven ends.  Here, the uneven ends are cut and the flowers are cut into short films.  These billets are then further processed into hot expanded steel tubes.  The steel is then stretched into tubes.  For seamless pipes, the main consideration is to stretch the steel to form the pipe.  The billet is heated to about 1204 degrees Celsius.  Steel stretches easily.  Stretching is done with the help of a special type of roller.  

The next step is to spray water on the heat pipe.  To return it to its normal phase, cold water is sprayed evenly over the pipe.  Then the pipe is coated or surface treated to obtain a good appearance.  

Thermal heating components (induction heating process).  Due to the limitation of seamless steel pipe manufacturer, the large hot rolled seamless steel pipe is generally below 457 mm, that is, below 508 mm.  So, if you want to find a seamless tube larger than this size, we have to do induction heating on the original (female) seamless tube.  The heat generated by the intermediate frequency heater is mainly used to expand the pipe to a certain diameter through expansion equipment.  This type of induction heated seamless steel pipe is rapidly accepted by customers around the world for its high efficiency, low cost, seamless quality and other advantages.  Now customers are using more and more seamless steel tubes.  Easy to weld in the process of use, the use of stable and reliable.
