Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.

A method and apparatus are disclosed for terminating flexible pipe body. The apparatus comprises an end fitting core portion (330), an end fitting termination portion (310) and a spacer ring member (335) locatable between the core portion (330) and the termination portion (310) for maintaining a whole anterior end surface of the core portion (330) and an opposed whole posterior end surface of the termination portion (310) in a spaced apart relationship.

An assembly comprising an end-fitting and an unbonded flexible pipe comprising several layers. The unbonded flexible pipe has an end-part entering the end-fitting at the front end and the layers of the unbonded flexible pipe being terminated in the end-fitting. The unbonded flexible pipe further comprises a first electrically conductive layer and a second electrically conductive layer, where the first electrically conductive layer is electrically insulated from the second electrically conductive layer. The end-fitting comprises a first electric zone electrically connected with the first electrically conductive layer, and a second electric zone electrically connected with the second electrically conductive layer, the first electric zone is electrically separated from the second electric zone, and the end-fitting comprises a third electric zone, the third electric zone being electrically separated from first electric zone and the second electric zone.

A system for a self-recoiling hose provides an expandible-length hose that automatically condenses to a smaller size upon completion of usage. The sheath includes a set of elastic fibers that is interwoven with a set of rigid fibers, thus allowing the expandable hose to elongate to a maximum length that is within a reasonable predetermined length range. This prevents the inner tube from expanding beyond its intended length. The apparatus further provides a connection mechanism for expandable hoses. The apparatus is designed to prevent any possible leakage between one or more expandable hoses and the apparatus. A threaded connector enables chain attachment of the expandable hose to other hoses. Another unit fits inside the inner channel of an expandable hose, while a third part surrounds the inner channel of the expandable hose. An annular fastener secures the outer channel of the expandable hose to the inner channel.
