In the method for the continuous production of a heat-insulated, corrugated line pipe (1) with at least one inner pipe (2), a corrugated outer jacket of the line pipe is first produced by means of an extruder (27) and a corrugator (28) and the inner pipe arranged in a foil tube together with a foam-forming starting material is guided into the corrugator, in which the outer jacket of the line pipe which has been corrugated before is filled with the heat-insulating foam. The device (10) provided for carrying out the method has a protective pipe (26) by means of which the inner pipe surrounded by the foil tube can be guided separately from the extrusion and corrugation of the outer jacket into the corrugator.

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.

Systems and methods according to the present invention utilize improved sleeves for insulating fluid (i.e., liquid and/or gas) conduits. For example, some blow dryers are equipped with a flexible conduit to convey heated air from a heater element to a nozzle for such purposes as material handling, material drying, or even hair drying, such as pet or other animal hair drying. An improved insulating tubular sleeve is provided with securing and/or mounting mechanisms to assist in maintaining sleeve position along a conduit and to reduce heat transfer externally from the conduit, such as by preventing direct contact between animal hair or skin or other materials and the conduit.

A tool can be used remove one or more outer layers of a tubular such as a flexible pipeline to enable an inspection on the remaining layers of the flexible pipeline. It allows the precise removal of outer layers of a flexible riser so that inspection can take place tubulars that otherwise could not be inspected with ultrasound.

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.

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.
