摘要： A corrosion-resistant pipe coupling made of carbon steel has on its inner surface an intermediate annular projection directed radially inward. At least an innermost part of the annular projection is formed of corrosion-resistant material such as stainless steel. The annular projection may be covered by a corrosion-resistant annular member which is secured by friction welding, electron beam welding, an adhesive or mechanical engagement. The annular member prevents corrosion of the coupling by corrosive fluids flowing in pipes.

摘要： A double-wall composite pipe is produced by inserting an inner pipe in an outer pipe, filling the inner pipe with cold water under pressure to cause the inner pipe to expand plastically into tight contact with the outer pipe, applying heat to the outer part of the outer pipe by high-frequency induction heating, thereby to establish a locally heated zone thereof around the circumference thereof and causing the heated zone to travel from one end to the other end of the outer pipe thereby to cause it to successively expand locally in diameter in the travelling heated zone. The pressure in the inner pipe then is removed, the pipes thereafter being permitted to attain the ambient temperature, thereby to obtain an interference fit therebetween.

摘要： A composite structure is manufactured by joining a first material, preferably made of a magnetically permeable material and having a first joining surface in which a recess having an overhang surface is formed, to a second material, preferably made of an electrically conductive material and having a second joining surface to be joined to the first joining surface of the first material. On the second joining surface is integrally formed a protrusion having an outer configuration substantially corresponding to the inner shape of the recess. The first and second materials are firmly mechanically joined to each other by, for example, a casting method, a rolling method, a pressing method, or a method utilizing plastic flow of the second material.

摘要： A method of producing an anchor bonded composite plate. Anchor cavities are formed in a base plate by placing a forming plate with a circular hole therethrough over the base plate at a selected anchor cavity location. A punch placed through the circular hole then applies a punching force to the base plate, thereby forming in the base plate an annular mound with a concentrically punched hole. The mound is next pressed with a leveling plate to cause the material of the mound to flow inside the punched hole forming an anchor cavity with an overhanging internally tapered surface. A cladding plate with a plurality of anchor holes is then placed on the base plate with its holes aligned with the cavities of the base plate. An anchor pin is inserted in the thus aligned openings and is plastically deformed to mechanically bond the plates together. The cladding plate and the base plate may be made of an aluminum alloy and a hard steel, respectively. The composite plate thus produced is applicable as a reaction plate for a linear motor vehicle and as a tank material for a liquid natural gas holder.

摘要： A multiple-wall pipe structure having at least two pipes tightly fitted one within another, one of which is of a corrosion-resistant material whereas the other is of a noncorrosion-resistant material. In order to protect against corrosion the end faces of the noncorrosion-resistant pipe and the seams between the two pipes, either during storage in the form of discrete pipe sections or in use by being welded or otherwise jointed end to end, a pair of anticorrosion rings of a corrosion-resistant material are integrally attached to the opposite ends of the fitted pipes so as to cover at least the end faces of the noncorrosion-resistant pipe and to seal the seams therebetween.

摘要： For reducing the diameter of any axially limited part of a metal tube, that part is heated externally by an annular heater while at least the adjacent part or parts of the metal tube are being cooled and held at a temperature sufficiently low to limit the free thermal expanison of the heated part. On cooling, the part that has been heated becomes less in diameter than the other portions of the metal tube. The complete length of the metal tube can likewise be reduced in diameter by moving the annular heater and the metal tube relative to each other in the longitudinal direction of the tube from one end to the other while at least the adjacencies of the part being heated are being cooled as by water. The same method is adaptable for the fabrication of wear-resistant dual wall pipe for the transportation of fluids, as is also disclosed herein.

摘要： Tensile residual stress in an annular welded joint part joining the ends of unit pipes is mechanically removed by applying repeated hammering strokes against the inner surface of the pipes over the entire joint part, thereby to cause such part to undergo local plastic deformation. The repeated hammering strokes, which have a peening effect, are applied by several automatically operating hammering devices mounted radially on a rotary head secured to and unitarily moving with a shaft which is driveable in rotation about its axis and in translation in its axial direction.

摘要： A composite cylinder head of an internal-combustion engine includes a bottom wall part to face the combustion chamber and a reinforcement part disposed on the side of the bottom wall part opposite to the combustion chamber and functioning as a back-up reinforcement of the bottom wall part. The two parts of the cylinder head are joined into a single integral structure. The bottom wall part is formed from a metal of higher high-temperature strength and lower thermal conductivity than those of the material of the reinforcement part. This cylinder head makes possible the use of a higher maximum pressure within the cylinder than that in the case of a conventional cylinder head.
