  • TEMPERATURE-CONTROLLABLE PIPE
    Publication number: 20120275774
    Abstract: A flexible pipe of multilayer structure which comprises the following layers, from the inside to the outside: an interior lining; an inner reinforcement layer; a layer of molded electrically conductive plastic; an outer reinforcement layer; and an exterior sheath. The electrically conductive plastic layer is in electrical contact with the two reinforcement layers, and the two reinforcement layers can be connected to a source of electrical current. It is thus possible to achieve efficient heating of the pipe, and it can therefore be used for conveying oil in cold regions.

  • Multilayer plastic pipe having a segmented barrier layer
    Patent number: 6528137
    Abstract: A multilayer plastic pipe comprising at least three layers, which in turn comprise at least two different polymers, which are a polymer A (barrier layer polymer), which is a particularly good barrier against permeation of the medium to be carried through the pipes embedded in a polymer B (sheathing polymer) in the form of at least one layer which is interrupted at least once by a fillet of polymer B.
