摘要： Heat transfer plates are stacked, each being provided with a plurality of passage holes, a flow-path forming gasket is interposed between peripheries of each adjacent ones of the heat transfer plates, thereby alternately forming a first flow path to pass a high-temperature fluid, a second fluid to pass a low-temperature fluid, and communicating paths to cause the fluids to flow in and out of the first flow path and the second flow path on opposite sides of each heat transfer plate, and communicating-path forming gaskets surrounding the passage holes are interposed between adjacent ones of the heat transfer plates, thereby forming a communicating path to cause a fluid to flow in and out of the first flow path and a communicating path to cause a fluid to flow in and out the second flow path. Each communicating-path forming gasket is made up of inner and outer gasket members arranged in two lines, the inner gasket member surrounding the passage holes while the outer gasket member surrounding the inner gasket member.

摘要： A flue gas air preheater and a method for the installation of air pipes for a flue gas air preheater (3), wherein a set of air pipes (7) is connected to said preheater, the method comprising: cutting an air pipe (7) connected to the preheater and detaching the portion of the air pipe (7) that is to be removed from the preheater for replacement; fitting a separate new air pipe (7a) in place of the air pipe portion to be removed; and connecting said new air pipe (7a) to the remaining portion (7b) of the air pipe (7) in a sealed manner, as an extension of it. In an example, the fixing is performed utilizing a fastening sleeve (13) fixed to the end of the new air pipe (7a) and inserting it in the remaining portion (7b) of the air pipe (7). In an example, the fixing is performed by means of a mechanical sealing solution (13d, 13f) without welding. The air pipe component for the flue gas air preheater (3) comprises: an air pipe (7a), and a fastening sleeve (13).

摘要： Provided are a gasket, a reactor using the same for sealing a spiral, and a manufacturing method thereof. The present invention improves a spiral sealing mechanism of a reactor wherein, spirals are continuously installed in the longitudinal direction between an inner pipe and an outer pipe coaxially arranged to form a flow path for a heat medium, so the seal between the spiral and the outer pipe is stably maintained and fabrication of the reactor is facilitated. The gasket (10) according to the present invention has a structure that the gasket is inserted in and coupled with the spiral (3), and thus does not need additional processing for combining the gasket (10). Therefore, since the gasket (10) and spiral (3) are coupled by lodging the spiral (3) into a channel (21) of the gasket (10), the assembly is facilitated. Furthermore, since the gasket (10) is evenly coupled in the outer circumference of the spiral (3), in which a cushion plate (40) made of resilient material is installed, breakage of the gasket (10) during assembly of the outer pipe (2) is effectively prevented and the post-assembly seal between the spiral (3) and the outer pipe (2) is stabilized.

摘要： A part of equipment includes a fluid conducting first region including a corrosion resistant first material, and a fluid conducting second region including a second material. The first region and the second region are either directly or indirectly joined by solid state welding to form a unitary fluid conducting part. A method for replacing at least one fluid conducting part of equipment is disclosed wherein a replacement part is provided that includes a fluid conducting first region including a corrosion resistant first material, and a fluid conducting second region including a second material. The second material is substantially identical to the material of a region of the equipment on which the replacement part is mounted. The first and second regions are either directly or indirectly joined by solid state welding to form a unitary fluid conducting replacement part. The replacement part is secured to the equipment by a process comprising fusion welding the second material of the second region of the replacement part to the substantially identical material of the mounting region of the equipment.
