GROOVE GEOMETRY FOR INJECTION MOLDED POLYPROPYLENE COATED FIELD JOINTS
In an injection molded polypropylene field joint of an oil or gas pipeline, the three- dimensional geometry of the injection molded/cast coating can have an influence on the stress placed on the line coating during cooling. Specifically, it has been found that molding or casting a coating having cir...

| description | In an injection molded polypropylene field joint of an oil or gas pipeline, the three- dimensional geometry of the injection molded/cast coating can have an influence on the stress placed on the line coating during cooling. Specifically, it has been found that molding or casting a coating having circumferential grooves, or other groove geometry, proximal to the interface with the line coating, will reduce line coating failure proximal to the field joint, in particular line coating failure related to the initial spooling/reeling of the pipe.
Dans un raccord de polypropylène moulé par injection d'un pipeline de pétrole ou de gaz, la géométrie tridimensionnelle du revêtement coulé/moulé par injection peut avoir une influence sur la contrainte appliquée sur le revêtement en ligne pendant le refroidissement. En particulier, il a été trouvé que le moulage ou le coulage d'un revêtement ayant des rainures circonférentielles, ou une autre géométrie de rainure, à proximité de l'interface avec le revêtement en ligne, réduira une défaillance de revêtement en ligne proximale au raccord, en particulier une défaillance de revêtement en ligne liée à l'enroulement/dévidage initial de la conduite. |
