An unbonded flexible pipe with a length and bore and an offshore installation are disclosed. The pipe comprises an internal pressure sheath, at least one metallic armouring layer surrounding the internal pressure sheath and at least one additional layer surrounding the metallic armouring layer. The metallic armouring layer comprises helically wound armouring elements which are at least partly covered by a viscous fluid having a kinematic viscosity of at least about 1000 cSt (ASTM D445 or ASTM D2170). The at least one additional layer surrounding the metallic armouring layer provides a gas escape route radially outwards from the metallic armouring layer beyond an outermost layer of the least one additional layer or to a lengthwise gas escape path in or between the at least one additional layer.

The present disclosure relates to the construction and use of feedlines in temperature-biased systems that include counter-biased hoses. The alignment and installation/uninstallation of the counter-biased hoses is enabled by a biasing tool with at least a first yoke having a first rotation point and a second rotation point, a second yoke having a third rotation point and a fourth rotation point, a first rod assembly connected to the first yoke at the first rotation point and connected to the second yoke at the fourth rotation point, and a second rod assembly connected to the first yoke at the second rotation point and connected to the second yoke at the third rotation point.

A flexible air duct contains a uniformly-spaced reflective insulation system, with or without bulk insulation, a liner, and an outer jacket that would allow a reduced amount or no amount of bulk insulation to be used to obtain a desired R-value insulation. The flexible air duct can be used to move conditioned air to one or more desired locations.

Described herein are corrugated heat protection tubes and methods of making the same. The heat protection tubes have improved heat resistance, improved abrasion resistance, and minimize or eliminate worker exposure to glass fiber insulating materials. The corrugated heat protection tubes can be used in automotive, transportation, and industrial applications, just to name a few.
