Abstract: A method for the individualized adaptation of the shape of components includes providing a basic material for producing the components. Next at least one unifying production method is selected. The components are then produced with a geometrically identical base shape by the unifying production method. Then at least one individualizing production method is selected. Then the shape of the components is adapted to at least two different final shapes by the individualizing production method that is different from the unifying production method. The final shape of each component differs from its basic shape.

Abstract: A method and system is provided for insulating piping installed in an exterior wall in a manner that protects the piping from freezing. Generally, the system includes an insulation block that has an interior side, an exterior side and a slot formed therein for receiving a pipe to be insulated adjacent the interior side, wherein the block is dimensioned particularly for installation into a building wall cavity. When installed, the block insures that the piping is positioned immediately adjacent the back surface of the interior sheathing material. The insulation block reliably provides a thickness of insulation material behind the piping such that the insulation material is positioned between the piping and the exterior wall surface while also maintaining the piping in contact with the rear surface of the interior wall sheathing to facilitate heat transfer from the interior of the building and into the piping.

Abstract: A sectional heat insulation jacket comprises a set of multi-layer insulation sections in which the layers are bound together by a fastening and fixing device. Adjacent insulation sections connect and they separate by assembling joints that are self-sealing. A mutual position of the adjacent sections is reliably fixed by the connecting device at each stage of heating. The self-sealing is accomplished by side flexible layers which incline under a sharp angle to the surface of an upper flexible layer. The sizes of the assembling joints between adjacent sections at levels of the upper and the bottom flexible layers are equal to the temperature expansions of these layers in longitudinal and transverse directions, correspondingly under the insulated entity's heating until an operating temperature is reached. A conical, helical spring shaped fastening rod further increases a length of metallic inclusions with high thermal conductivity form an insulated entity and reduces heat loss.

Abstract: An insulation arrangement for pipes, especially for pipes of a pneumatic system in a passenger transport aircraft, essentially includes at least one insulation layer (6) as well as an outer sheath (3) consisting of titanium foil (31). The outer sheath (3) is connected, in a first end section (32) and in a second end section (33), respectively with a termination profile (7), and thereby a shell (9) with at least one longitudinal seam (13) is formed, into which the insulation layer (6) is insertable.

Abstract: An insulated duct-wrap insulating product for an air duct that incorporates a wicking media to transport condensed water on the duct surface to be evaporated into the atmosphere. A wicking fabric, or fibrous media, incorporated as part of the insulating duct wrap is in contact with the metal air duct surface. A portion of the wicking fabric extends into the interior of the air duct, typically through joints in the duct system. When water vapor condenses on the air duct surface it is transported by the wicking fabric and evaporated from the wick surface within the air stream being transported by the ducting system.

Abstract: A tape structure and/or closure system particularly useful with cylindrical insulation segments for pipes. The tape structure provides both a temporary and a permanent closure. The tape structure includes a substrate and a layer of pressure sensitive adhesive disposed on both sides of the substrate. One of the layers of pressure sensitive adhesive is covered by a release liner, while the other layer of pressure sensitive adhesive is exposed. The exposed layer of pressure sensitive adhesive is applied to one of either the underside of a flap covering a slit in the insulation jacket, or to the outer surface of the insulation jacket. The release liner is divided into two portions, one of which is narrow with respect to the other portion. The narrow portion of the release liner is removed, and a narrow strip of the second layer of pressure sensitive adhesive is attached to the other of either the outer surface of the jacket, or the underside of the flap to form a temporary closure.

Abstract: A thermally insulating cover structure adapted for covering a hot pipe comprises a heat insulation layer (2), a filler layer (3) and a jacket (6), which is provided with drain openings (5). The filler layer comprises a material that is permeable to water. The drain openings are shielded against entry of water, while they allow drainage of water from the filler layer into the environment. This cover structure is in particular suited for outdoor pipelines, where moist conditions may arise. The invention also provides a pipeline and a method of providing a pipeline with a thermally insulating cover structure.

Abstract: A hose for conveying free-flowing materials, such as coating powder made of an electrically non-conductive or poor conductive material is characterized in that a wall member of an electrically conductive material is installed into the wall of the hose, said wall member extending radially across the cross section of the wall and axially across the length of the hose, and being grounded towards the outside and having an approximately sector-shaped cross section as in a welding seam in a manner so that on the one hand a favorable discharge of undesired electric charges is achieved and on the other hand a caking at the inner wall of the hose is virtually excluded.

Abstract: A ventilation duct includes an envelope lined on the inside by insulation panels. The panels have a lining on the side of the flow channel of the duct and on at least one part of at least one of transverse edges of the duct. This lining extends over at least one part of each of both sides of the edge and is integrated with the panel. Z shaped sections may be used to hold adjacent panels.

Abstract: A metal pipe and method of forming the same with an integrally formed liner for use in corrosive and abrasive environment utilizes a liner formed of a comparatively thick polymer which is thermally bonded to the metal pipe. An intermediate polymer/adhesive layer is applied to the metal pipe to facilitate thermal/chemical bonding. The intermediate layer is preferably applied to the sheet metal in a pre-treatment process prior to roll forming ribs into the sheet metal. The polyethylene liner is applied after the pipe has been formed, to provide a smooth, hydraulically efficient surface which is resistent to the corrosive action of sulfuric acid and the like encountered in sanitary applications, as well as abrasion caused by the flow of water-born debris such as dirt and gravel as is encountered in culvert applications.

Abstract: The present invention relates to a combination of an A and B adhesive reacting together through a scrim material in a laminated combination, and wherein the B adhesive has great adherence characteristics to a vinyl nitrile foam, and the A adhesive has great adherence characteristics to itself. Thus a laminate of the A adhesive/scrim/B adhesive to each side of a slit in a vinyl nitrile foam tubular insulation, with appropriate release liners covering the outside A adhesive, has been found to be particularly effective. When the release liners are removed and the A adhesives pressed together, a very strong bond is created closing the slit in the vinyl nitrile foam insulation holding the tubular vinyl nitrile foam in place on the tubular member to be insulated. Normally, this is utilized in an air conditioning application with the piping or tubes running from the compressor to the air conditioning unit, and wherein vinyl nitrile foam insulation has proven to be the best insulating material for this application.

Abstract: A tubular sheath made from plastic material used for the mechanical and/or thermal protection of electric cabling is wrapped in a strip of sound-insulating material, the lateral parts of which have been inserted inside the sheath through the slit. The width of the strip, preferably produced from felt, is substantially equal to the sum of the external and internal perimeters of the plastic sheath.

Abstract: An exhaust hose for an internal combustion engine is encase in a screen sleeve. The hose has a metal tube on the inside which can withstand the temperatures of the internal combustion exhaust fumes. The metal tube has ribs which enable it to be bent without kinking, but also provides significant strength to the hose. A thermal insulation layer is placed around the metal tube. The thermal insulation layer may include a gauze wrapping, allowing the inner portion of the thermal insulation layer to breath. The screen sleeve provides an outer layer for the exhaust hose. Preferably the screen sleeve is slightly larger in diameter than the thermally insulated metal tube, such that the screen sleeve fits loosely.

Abstract: A synthetic resin pipe which includes two identical complementary, extruded semi-cylinders joined by electromagnetic bonding along abutting longitudinal edges to form a smooth walled cylindrical pipe. In one embodiment of the invention, the smooth walled pipe forms an internal sleeve or liner within an external corrugated pipe having contiguous circumferential corrugations over its length, and having the troughs of the corrugations bonded to the outer surface of the internal sleeve.In the method for forming the pipe, two identical flat plastic sheets are extruded, then vacuumed formed into semi-cylinders each having radially outwardly projecting longitudinal flanges extending from opposite side edges thereof.
