What is the method of producing pipes?
There are many kinds of pipes and their production methods are various. The common production methods are as follows： (1) Production of pipes by thermal pressure processing. There are many ways to produce hot rolled seamless pipes. The tubes used for hot rolled tubes are hollow billets, solid billets or steel ingots. In hot rolling production, the punching is to pass the heated pipe blank into a thick-walled capillary tube on a perforating machine, and roll the thick-walled capillary tube into a finished tube on the pipe rolling machine to the required wall thickness and accuracy, and then pass the sizing, reduction or expansion Diameter, and finally cooling and finishing.The hot-pressing method is mainly used for rolling pipes, but for non-ferrous metals, rare metals that are difficult to deform, and precious metal machines, special-shaped profile pipes are produced by extrusion. (2) Pipes are produced by cold pressure processing. The cold-pressure processing method mainly r...
