Before further working, the shell needs to be reheated to proper rolling temperature for the final rolling process.
|
The hot shell is run through a descaling unit to prepare the O.D. surface for rolling and run through the SRM. At this stage the final O.D. and wall thickness is established for the pipe.
|
Upon exiting the SRM, the pipe are allowed to cool on a walking beam cooling bed. Sample inspections are also done at this point.
