Abstract
A tube is thermally insulated for protecting a fluid flowing therethrough from a high includes temperature surrounding environment of a gas turbine engine. The tube includes a conduit, an insulating layer wrapped around the conduit, and an elongated contractible braided sleeve for preventing a separation of the insulating layer from the rigid conduit. The contractible braided sleeve is flexible along a longitudinal axis thereof and removably pulled over the insulating layer to snugly surround and maintain the insulating layer around the conduit.
