Today, specialized steel pipes are made in accordance with all the requirements of GOST 13663-86. In most cases, the pipe is made using the method of deformation. The choice of it is precisely due to the fact that in this method of manufacturing, the high accuracy of the size can be observed. In addition, it is possible to make such a pipe using a seamless way. Note that profile pipes are produced mainly from electric welding or straight -line pipes.
