    摘要： An improved pipe liner and associated methods, including a method of manufacturing the improved pipe liner and a method of lining a host pipe with such a pipe liner. The invention solves the problem of gas permeation through a polymer liner in hydrocarbon service which can result in corrosion of the host pipe and can also cause liner collapse. Corrosion occurs due to contact between corrosive species and the host pipe itself. Gases (307) can also accumulate in an annulus between or within the liner (305) and the host pipe (303) and expand during operational de-pressurisation of the pipeline, causing collapse of the liner. The improved pipe liner comprises a barrier layer (311), which prevents permeation through the liner, surrounding an inner polymer pipe (305A) and optionally covered by an outer polymer pipe (305B). The inner polymer pipe is porous which permits free movement of gas between the internal bore (302) of a lined pipe and the barrier layer, so as to prevent accumulation of gases anywhere in the lined pipe, while ensuring that gases do not permeate to, and damage, the host pipe. The liner can be inserted using Swagelining, roll-down, or any other suitable close-fit lining techniques, without compromising the effectiveness of the barrier layer.

    摘要： Down-hole tools, methods of manufacturing the down-hole tools and methods of running the down-hole tools downhole are generally described herein. The down-hole tools generally include a sealing assembly adapted for use down-hole, wherein the sealing assembly includes: a substrate including an elastomeric material; and a heat shrink film adhered to at least a portion of the substrate, wherein the heat shrink film includes a thickness when adhered to the at least a portion of the substrate in a range of about 7.5 mil to about 30 mil and exhibits an Elmendorf tear strength (as measured by ASTM D-1922) in a range of about 1000 g to about 5000 g.

    摘要： A heat shrink apparatus for heat shrinking a shrink film to a bladder. The heat shrink apparatus may include a support structure, a bladder support system, and a heat chamber. The bladder support system for supporting the bladder thereon may have two spaced apart parallel rows of a plurality of resilient members pivotally and/or resiliently attached to the support structure. The heat chamber may be hollow with opposing end openings and may have one or more heating elements therein. The heat chamber may translate over the shrink film and the bladder along the support structure between the two spaced apart parallel rows, shrinking the shrink film to the bladder. As the heat chamber translates, it may contact ends of the resilient members, thereby pivoting or deflecting the resilient members from a first position to a second position such that the heat chamber can pass between the two parallel rows.
