It is worth saying that hot-deformed seamless pipes https://ukrstarline.ua/ru/chernyj-metalloprokat/stalnaya-truba/stalnaya-truba-goryachekatanaya-kruglaya are cheaper than others. However, there is a special rolling method that cannot produce small-diameter pipes. This type of metal rolling is very flexible and withstands high pressure and temperature drops. The manufacturing process here is the same as for cold-deformed pipes. However, the peculiarity here is that the size is formed at a temperature below crystallization. During this process, the pipe must pass through a rolling mill and form the required size.
