Heat-expanded seamless pipe is the heat-expanded pipe we often say. It is a steel pipe with low density but strong shrinkage. Heat-expanded seamless pipes are the heat-expanded pipes we often say. Steel pipes with relatively low density but strong shrinkage (seamless steel pipes) can be referred to as heat-expanded pipes for short. A rough tube finishing rolling process in which the diameter of a pipe is enlarged by a diagonal rolling method or a drawing method. Making steel pipes thicker in a short period of time can produce non-standard, special types of seamless pipes, with low cost and high production efficiency, which is the development trend in the field of international pipe rolling.
