Abstract: The invention refers to a method of brazing together thin heat exchanging plates of an iron based base material provided with port holes and a pressing pattern of elevations and depressions over the heat exchanging area of the plates and, if present, also over the distribution area to a plate heat exchanger. The plates are coated with brazing material and are arranged such that contact between elevations and depressions in adjacent plates is obtained prior to the brazing together. The plates are then brazed together at the resultant contact points. Only 5-40%, preferably 10-30%, of the heat exchanging area and the distribution area are coated with brazing material prior to the brazing.

Abstract: During implementing a composite metal part by compaction of an insert having reinforcing fibers in a metal body or container, gas used for compaction may enter the cavity formed in the container for receiving the insert between a lid covering the insert and the container, which can prevent or degrade compaction and diffusion welding of fiber sheaths of the insert therebetween and/or with walls of the cavity. To solve this problem, the present method includes initiating isostatic compaction by a phase including raising and maintaining temperature, followed by a phase including hot-feeding pressurized gas, and machining an assembly to obtain the part. The temperature raising phase includes a diffusion pre-welding of material rigidly connecting the pressure-adjusted walls of the lid and the container. The method can be used for designing parts having a tensile and compression resistance, such as parts for aircraft landing gear.

The method also includes inserting the metal plug into the tapered opening in the casing outer wall, and welding the metal plug to the casing.

Abstract: A method of remanufacturing an injector involves an original lead extending from an overmold block. A milling cutter is used to mill a cavity into the overmold block to provide access to the original lead. The milling cutter splits the original lead into a remainder portion and a discard portion. A replacement lead is inserted into the overmold block to overlap with the remainder portion, and the overlapping leads are soldered to each other. The exposed overlap area is encapsulated with filling material. The original lead is preferably cut such that a tip of the remainder portion is angled, pointed, or otherwise shaped to increase the surface area that is exposed at the tip. The increased exposed surface area increases the area over which the replacement lead and the remainder portion make contact with each other when overlapping. Greater contact between the soldered leads strengthens their connection.

Abstract: Provided is a method of partially replacing a shell plate of a tower or a vessel, capable of partially replacing the shell plate of the tower or the vessel in a short construction period at low construction cost. The method of partially replacing a shell plate of a main distillation tower is a method for replacing a cylindrical shell plate portion 2 serving as one portion of the shell plate 1 of a main distillation tower, wherein two facing parts located in the circumferential direction of the cylindrical shell plate portion 2 to be replaced are partially cut off and removed, new partial shell plates 3 are respectively attached to openings 6 generated by the removal, and the removal and the attachment are repeated, so that the cylindrical shell plate portion 2 is replaced. The new partial shell plate 3 is obtained in a case where the cylindrical shell plate portion 2 is substantially equally split into a plurality of sections in the circumferential direction.

Abstract: A shape memory polymer is initially fabricated to a size where its peripheral dimension will be at least as large as the borehole wall in which it is to be deployed. After the initial manufacturing the material temperature is elevated above the transition temperature and the material is stretched on a mandrel to retain its inside dimension as its outside dimension is reduced to size that will allow running the seal to a desired subterranean location without failing the material during the stretching. The material is allowed to cool below the transition temperature to hold the new shape. The material on the mandrel is then secured to a tubular string and delivered to the desired location. Wellbore fluid at given temperature raises the material again above the transition temperature, which causes the material to revert to its originally manufactured shape.
