| Dernières réponses | |  Hot rolling of pipes https://kompromis.info/2024/06/18/stalnaja-truba-gorjachekatanaja-kruglaja.html is made from a solid steel blank, which is heated to a temperature of +1200C. A hole is made in it using a drill of the required diameter. Further processing is carried out on shafts, where the required diameter and wall thickness are obtained, after which cutting is carried out. The product is obtained with minimal accuracy of the specified dimensions, high errors in wall thickness and surface defects. The hot deformation method allows producing pipes of only large diameters |
