06a - calibrating pipes The calibration process is used to make pipes with circularity tolerances correct with international standards.
The pipe, after always tends to flatten that welding processes so you have to bring it back to the correct conditions of circularity.
In addition to flatten that the pipe heated by the welding process is retort losing its linearity must also then be straightened.
In addition to the welds to deform the pipe can also be thermal hardening treatments, in that case, the adjustment process must also be done after the thermal treatment.
The calibration presses must make the circular tube and right, ready for subsequent processing.
