Hollow Round Steel Pipe
Open at both ends and has a hollow concentric section, its length and the perimeter of the larger steel. The specifications of the steel pipe with the external dimensions (such as outer diameter or side length) and internal diameter and wall thickness, its size range is very wide, from the diameter of a very small capillary tube to the diameter of up to several meters of the large round steel pipe. Round steel tubes are used in pipelines, thermal equipment, the mechanical industry, petroleum and geological drilling, containers, the chemical industry and for special purposes.

Hot rolled seamless steel tube pipe
Hot rolled seamless steel pipe is a major category of seamless steel pipes, which are divided according to production methods. Hot rolling is relative to cold rolling. Cold rolling is rolling at room temperature, while hot rolling is rolling above the recrystallization temperature. Seamless steel pipes are relative to welded steel pipes. Seamless steel pipes are usually made by perforating round steel, while welded steel pipes are usually made of steel plates welded in different ways.
