Fremgangsmåde til feltisolering af forbindelsessamlinger til fluidtransportrörledninger

Method for the field insulation of connecting joints (3) for fluid transport pipelines (1, 2), where said pipelines are each composed of a metallic tube (101, 102) partially insulated with at least one layer (201, 202) of an anticorrosive material and connected to each other by joint (3) to weld the insulation free final extremities of said metallic tubes (101, 102), comprising the following phrase: positioning an essentially cylindrical mold (6), approximately shaped around the extremities next to the joint (3) of said layer (201, 202) of anticorrosive insulation and around the insulation-free extremities of said metallic tubes (101, 102), so as to obtain a hollow space (9, 9´) between said extremities and the internals walls of said mold (6); pouring into said mold (6) a sealing resin (10) capable of filling said hollow space (9, 9´) and to rapidly solidify while effectively adhering to the extremities of the said layers (201, 202) of anticorrosive insulation and of said metallic tubes (101, 102); removing of said cylindrical mold (6) after solidification of the said resin (10).
