Hot-rolled steel and cold-rolled steel have different causes of residual stress, so the distribution on the section is also very Differences between Hot Rolled and Cold Rolled Seamless Aug 19, 2020 · The outer diameter of hot-rolled seamless pipe is generally greater than 32mm and the wall thickness is 2.5-75mm. The diameter of cold-rolled seamless pipe can be up to 6mm and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm and the wall thickness is less than 0.25mm.

Hollow sections For structural and mechanical application

differences. The main difference is that hot finished hollow sections pass through a furnace and have a much tighter corner profile as a result of the metal flow during the forming process (EN10210-2). Cold formed, on the other hand, exhibit a high degree of cold working in the corner regions during the forming process. This means that they Hot Finished Seamless & HFS Pipes and Tubes Hot Finished Seamless (HFS) as differentiated from Cold Drawn Seamless (CDS) pipes and tubes are made by heating a solid billet or bloom and then punching or piercing it to make a hollow out of it. This hollow is subsequently passed through one or multiple stands with or without a tool inside to give it the final pipe or tube dimensions.
