 Tension reduction rolling is the last hot rolling process in the production of seamless steel pipes, which plays a decisive role in the control of product quality. The tension reduction of seamless steel pipe is a continuous rolling process without mandrel. During the rolling process, the outer diameter and wall thickness of the rolled piece are changed by the radial pressure of the roll.The axial direction is affected by the friction force of the roll, which changes the wall thickness, and is also affected by various factors such as tangential stress and temperature changes. Advantages of steel pipe tension reduction (1) Reduce the specifications of the required tube blanks and improve the production efficiency of the tube rolling unit. The pipe rolling unit only produces a few specifications, and after tension reduction, various specifications of finished steel pipes can be obtained. (2) It can reduce the number of production tools in the front process and improve the operation ...

 Alloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standard of alloy pipe and its industry, annealing and tempering of alloy pipe changes its mechanical properties and achieves the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its chemical composition contains more Cr, and it has high temperature resistance, low temperature resistance and corrosion resistance. There are no alloy components or very few alloy components in ordinary carbon seamless pipes. The mechanical properties of alloy pipes are varied and easy to adjust, so they are widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries. The use and classification of alloy pipes Alloy steel pipes are mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-t...

 Non-destructive testing refers to the inspection methods used to inspect the internal or surface defects of the material, or to determine some physical quantities, properties, and organizational states of the material without destroying the original state and chemical properties of the material to be tested. There are four commonly used non-destructive testing methods for seamless tubes: 1. X-ray inspection Suitable for detecting internal defects in metals, non-metals or other materials. The energy of the light quantum of X-ray is much greater than that of visible light, it can penetrate objects that visible light cannot penetrate, and while penetrating objects, it will have complex physical and chemical interactions with matter, which can ionize atoms and cause certain substances to emit light. Fluorescence can also cause photochemical reactions in certain substances. If there is a defect in the local area of the workpiece, it will change the attenuation of the object to the ray ...
