Least problematic practice is to form plates perpendicular to the weld direction and with hardfacing on the inside. *These radii are suitable for plate bending and forming. It is not recommended to roll plate (13 + 17) and (13 + 20), and care should be taken when rolling (12 + 12) due to high risk of increased cracking, spalling and base material tears.

Forming plates to facilitate this, is possible, but cracking and spalling could occur if it is not done with caution. Rolling pipe with hardfacing on the outside is more easily done by welding a pipe of the correct diameter with hardfacing, rather than rolling it from plate. Back to contents page
