Contexto:
"Parallel roll
The body is not definitely straight. API admits an out-of-straightness= 4/1000. This out-of-straightness leads to vibrations during the rotation of the pipe. In order to reduce the amplitude of the vibration, the table has parallel rolls. These devices have rubber dampers, that dissipate the energy and an electric system to accompany the movement of the pipe, ensuring the ***pipe-rolls*** contact. This contact is also benefited by the own weight of the pipes with a diameter beyond 5 ½”.

Roletes para canos?
