Title (EN) WELDING PURGE DAM WITH APERTURED PURGE PLATES
(FR) BARRAGE DE PURGE DE SOUDAGE À PLAQUES DE PURGE À OUVERTURES
Abstract:
(EN) A water-degradable welding purge dam apparatus for purging a weld zone of a pipe assembly having first and second pipes having respective first and second pipe ends to be welded together at a root gap. The purge dam apparatus includes a blocking plate assembly having an outer blocking plate, an inner blocking plate, and zero or more interior blocking plates. The blocking plate assembly may be formed from one or more water degradable materials to facilitate removal of the purge dam apparatus from the pipe assembly using an aqueous fluid following welding. At least one of the blocking plates may include a plurality of fluid flow apertures to aid distribution of the aqueous fluid through the blocking plate assembly. If desired, first and second ones of the blocking plate assembly may be ganged together by an interconnection assembly to form a ganged set of blocking plate assemblies.
(FR) L'invention concerne un appareil de barrage de purge de soudage dégradable dans l'eau permettant de purger une zone de soudure d'un ensemble tuyaux comportant des premier et second tuyaux ayant des première et seconde extrémités de tuyau respectives devant être soudées ensemble au niveau d'un espace de base. L'appareil de barrage de purge comprend un ensemble plaques de blocage ayant une plaque de blocage externe, une plaque de blocage interne et une ou plusieurs plaques de blocage intérieures. L'ensemble plaques de blocage peut être constitué d'un ou de plusieurs matériaux dégradables dans l'eau en vue de faciliter le retrait de l'appareil de barrage de purge de l'ensemble tuyaux à l'aide d'un fluide aqueux après le soudage. Au moins l'une des plaques de blocage peut comprendre une pluralité d'ouvertures d'écoulement de fluide de sorte à faciliter la distribution du fluide aqueux à travers l'ensemble plaques de blocage. Si on le souhaite, des premier et second ensembles plaques de blocage peuvent être accouplés l'un à l'autre au moyen d'un ensemble d'interconnexion de sorte à former un ensemble d'accouplement d'ensembles plaques de blocage.
