    Abstract: A protector configured in such a manner that, when mounted to a pin or a box of a threaded joint for a pipe with at least one of the pin or the box lubricated with a solid lubricating coating, the protector prevents damage to the solid lubricating coating on a screw thread section of the threaded joint. The protector is a tubular body provided with a screw thread section formed on the inner peripheral surface or the outer peripheral surface of the tubular body. The screw thread section of the protector engages with at least a part of a screw thread section provided to the pin or the box to be protected, and preferably the screw thread section of the protector engages with three to five perfect screw threads. The height (H1) of the screw thread section of the protector and the height (H2) of the perfect screw thread of the pin or the box to which the protector is mounted satisfy the relationship of H1 > H2, and the difference between H1 and H2 (= H1 - H2) is greater than the maximum thickness, measured at the screw thread crest, of the solid lubricating coating which covers the screw thread section of the pin or the box.

    Abstract: Un aparato para ensayos 1 apto para evaluar el desempeño de una unión roscada en tubos destinados a la industria del petróleo que utiliza un primer tubo de acero P1 y un segundo tubo de acero P2 dotado de una base 2 que sostiene un primer tubo de acero P en una posición vertical con un extremo superior del primer tubo de acero P1 extendiéndose por arriba de la base y la parte remanente dispuesta bajo tierra. Un miembro de soporte 3 montado en la base 2 que se extiende al costado del primer tubo de acero P1. Un segundo tubo de acero P2 es suspendido por encima del primer tubo de acero P1 por medio de un mecanismo de suspensión 4. Una unión roscada puede ser conectada y desconectada por medio de una primer y segunda mordaza 5 y 6 que giran al segundo tubo de acero P2 con respecto al primer tubo de acero P1. Un estabilizador 7 montado en el miembro de soporte 3 puede limitar el radio de giro del segundo tubo de acero P2.
