What Is The Production Of Threaded Galvanized Seamless Steel Pipe

  has the advantages of beautiful external appearance, convenient operation, safety, high corrosion resistance, etc., so it can be widely used in our work and life. Especially in the Middle East countries In the national projects with strict requirements, it is often used for the comprehensive application of thickened pipe hoops and precision thread buckles, which are widely used for the transportation of water, gas, oil and other fluids.
  Manufacturing process of threaded galvanized steel pipe:
  After the manufacture of seamless steel pipes, after pickling, according to customer requirements, galvanizing treatment, there are generally three kinds of galvanizing, respectively, hanging plating blow plating and galvanized belt, hanging seamless steel pipe plating process is the most zinc It can reach more than 500g2 per square meter, and the blown seamless steel pipe is about 300g per square meter, while the welded pipe with galvanized strip is the most used and the least galvanized amount is only 60-150g per square meter.
  The thread processing business can only be started after the galvanization of the seamless steel pipe is completed. The thread buckle processing is made by a professional lathe, which requires a taper thread buckle type. There are often standards such as the American standard and the British standard. Thread processing is carried out at the end to clear the thread inspection thread data, and then a pipe hoop is added at one end, and a plastic cap wire is added at one end.
  The manufacturing of the pipe hoop is the most elaborate, which is the focus of the whole product, because it is the part with the largest pressure bearing in the whole project. The material requirement of the pipe hoop is higher or lower than the material of the seamless steel pipe itself. After cutting from round steel, the lathe is processed to fix the size, then the thread is processed, and finally the thread and size are inspected.
