Systems and methods for pipe lining systems and methods of use are described. Systems and methods may include a CIPP lateral liner that is inserted into a bladder forming a CIPP liner assembly that can be inserted into a pipe line for a pipe repair. CIPP liner assembly can include a membrane that produces superior results compared to the prior art. A backing ring may be used with these systems and methods.

Provided is a patch for a fluid line, a system employing a fluid line, and a method for sealing a fluid line. The fluid line, in one aspect, includes a tubular, and a sleeve of expandable metal positioned about the tubular, the sleeve of expandable metal comprising a metal configured to expand in response to hydrolysis and thereby seal a leaking section of a fluid line.

A downhole packer assembly includes a body part, an expandable tubular packer element surrounding the body part, and a first end and a second end of the expandable tubular packer element are fixedly connected with the body part, providing an expandable space fillable with liquid during expansion, and a metal sleeve surrounding the expandable tubular packer element. A restriction unit has an axially movable part movable between a first axial position in which the axially movable part at least partly overlaps the expandable tubular packer element and a second axial position in which the axially movable part has been axially displaced in relation to the body part away from the expandable tubular packer element.

Expandable tube members that are fabricated from a composite material that includes a structural plastic, which structural plastic includes phase change materials that undergo a permanent expansion upon exposure to wellbore conditions. This permanent expansion of the structural plastic causes the expandable tube member to expand radially and/or longitudinally without the use of an expansion tool. The expandable tube member can be used to control fluid loss, patch wells, stabilize a formation in a wellbore, enhance flow, provide sand screening, and repair damaged pipes, casings, or liners.

The present disclosure relates to a method for repairing a partially collapsed pipe. The method comprises fitting a mesh stent around the outside of an actuation assembly of a pipe repair apparatus, and positioning the pipe repair apparatus within a portion of the pipe, at least a part of the portion of the pipe being partially collapsed. The method also comprises causing actuation between a retracted configuration and an extended configuration such that the partially collapsed part of the pipe changes from a partially collapsed form towards a non-collapsed form. The method also comprises removing the pipe repair apparatus from the pipe and leaving the mesh stent in the portion of the pipe.

Packer for use when repairing underground pipe systems, where said packer comprises a flexible and/or expandable main body portion surrounding a hollow interior, said body portion having an elongated shape defining first and second ends in either end of the main body portion, and where heating means are arranged in the packer for heating the packer or at least the surface of the packer, and means are provided for pressurizing the interior of the packer thereby expanding the packer.
