  • Publication number: 20100037973
    Abstract: An efficient flexible hose construction is provided which incorporates resistance, when subjected to high negative pressure loads, to the collapse failure known “rollover” or “shingling”. The construction relates to a means of increasing the torsion capability of a flexible hose where the hose is formed from a helical wire that is coated and thereafter is connected to and supports a shroud or cover. Improved resistance to rollover lies in mechanical enhancements to the interface between the helical wire and the coating material, where the enhancement assists in maintaining the wire and coating as an integral unit and prevents separation leading to shingling under high vacuum pressures. The mechanical enhancement requires use of a specialized cross-section for the helical reinforcing wire.

The tubes may be used to furnish hydraulic fluid or chemicals into the well bore. The contents may be pressurized or under vacuum. The jacketed tubes are hermetically sealed. The tubes, which may be 1 inch in diameter, are joined using compression fittings. Tear cords are used to facilitate removal of the protective jacket without damage to the tube surface thereby facilitating the placement of compression fittings and maintaining the integrity of the tube wall.

  • Patent number: 7302973
    Abstract: A reinforced flexible pipeline (1), which has an inner liner (3) whose inner side engages an inner reinforcement layer (2) that may be formed by a so-called carcass, and on whose outer side at least a strength-imparting reinforcement layer (4, 5, 6, 7) is provided, has an additional barrier layer (9, 10, 11) which is arranged between the inner liner and the inner reinforcement layer. The additional barrier layer is thermally insulating and/or chemically protecting. The additional barrier layer may be formed as a tape (9) which is wound around the inner reinforcement layer, or may be composed of locking profiles (10, 11) which are wound around the flexible pipeline in a helix. The additional barrier layer (9, 10, 11) may be made completely or partly of a polymer which may be thermoplastic, or is cross-linked completely or partly. Hereby, the pipe may be protected against temperatures above e.g. 13° C. and may also be protected against attacks from methanol that contains water.
