摘要： A product is disclosed which is resistant or immune to carburization, metal dusting, coking, oxidation, and has sufficient mechanical strength for use at temperatures greater than 400°C. The product consist of a load-bearing member and a corrosion resistant member, wherein the corrosion resistant member is a Cu-Al-alloy comprising Si. Furthermore, the use of the product in CO-containing atmospheres, and/or hydrocarbon containing atmospheres or solid carbon containing processes is disclosed, as well as a method of resisting carburization, metal dusting, coking and oxidation.

摘要： The invention relates to a multiple walled tube rolled from a metal strip for transporting fluids, specifically in automobile engineering, where the metal strip consists of stainless steel. The invention further relates to a method for manufacturing such a tube, where the stainless steel strip is brazed in an H 2 atmosphere after rolling, specifically by the addition of a brazing solder.

摘要： In a method of producing a double-walled structure, such as a silencer for use in a ventilation duct system, use is made of an arrangement having a forming head (5) for forming helically-wound lock-seam tubing (2). In the forming head (5), a perforated metal strip (7) is helically wound together with an air-permeable cloth strip (13) such that the tubing (2) fed out of the forming head (5) has an outer cover of said cloth (13). The tube assembly consisting of the perforated tube and the cloth cover is provided with an outer tubular layer of insulating material and then inserted in a casing which makes the silencer complete.

摘要： A metal pipe (11) and method of forming the same with an integrally formed liner for use in corrosive and abrasive environments utilizes a liner formed of a comparatively thick polymer (16) which is thermally bonded to the metal pipe (11). An intermediate polymer/adhesive layer (80) is applied to the metal pipe (11) to facilitate thermal/chemical bonding. The intermediate layer (80) is preferably applied to the sheet metal (11) in a pre-treatment process prior to roll forming the ribs (12) into the sheet metal (11). The polyethylene liner (16) is applied after the pipe has been formed, to provide a smooth, hydraulically efficient surface which is resistant 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.

摘要： A dual weld for joining strips to be formed into coiled tubing. Tubing is formed from a first strip (15a) and a second strip (15b), the first and second strips of the same width. A planar end surface (Pa) is formed on an end of the frist strip. Similarly, a planar end surface (Pb) is formed on an end of the second strip. A composite strip is formed by welding the planar end surface of the first strip to the planar end surface of the second strip to form a dual bias weld. Excess-weldment is then removed from top, bottom and edge surfaces of the composite strip such that the width of th weld is identical to the width of the first and second strips. Coiled metal tubing is then formed from the composite strip.
