Abstract: 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).

Abstract: A flat flexible hose for transporting a fluid, for example water, is adapted to move between an inoperative position having a flattened configuration and an operative position, in which the hose expands radially under pressure from the fluid. The hose has a first inner layer defining an axis, a second covering layer, and a reinforcement textile layer therebetween. The first and second layers are made of a first and respectively a second thermoplastic elastomeric material adapted to adhere to each other. The reinforcement textile layer is made of rigid textile yarns which at least partially have a respective first and second predetermined inclination opposite to each other so that the length of the hose remains unchanged both in the inoperative and the operative positions. The reinforcement textile layer is a knitted layer with tricot chain stitches with rows of stitches and courses of stitches made of chain stitches.

Abstract: The present invention relates to the field of extensible flexible hoses, especially but not exclusively intended for use for irrigation, and more specifically relates to a new configuration for such a hose, and the relative production process.
