摘要： PROBLEM TO BE SOLVED: To provide a surface-treated alloy having a low thermal expansion coefficient in which the occurrence of a stress corrosion cracking can be prevented. SOLUTION: The surface of a first base material 6 is coated with a first cathodic protective coating layer 7 having cathodic protective action to form the surface-treated alloy 5 having low thermal expansion coefficient. The first base material 6 is composed of a low thermal expansion coefficient alloy 10 having a compressive residual stress layer 9 on the surface. The first cathodic protective coating layer 7 is composed of inorganic or organic zinc-rich paint, and the inorganic or organic zinc-rich paint consists of zinc dust 11 and resin 13. The compressive residual stress layer 9 is formed by blasting treatment such as sand blasting, and ruggedness for improving the adhesion of the inorganic or organic zinc-rich paint can be formed at the surface of the first base material 6 by the blasting treatment. The occurrence of stress corrosion cracking under corrosive environment can be prevented by the first cathodic protective coating layer 7 and the compressive residual stress layer 9.

摘要： PROBLEM TO BE SOLVED: To provide a low-temperature material treating facility which reasonably connects a piping 1 made of Fe-Ni-based low-thermal-expansion-coefficient alloy with a pipe coupling or an apparatus made of stainless-steel. SOLUTION: An extension straight pipe portion 3 made of a same material is provided for a piping 1 made of Fe-Ni-based low-thermal-expansion-coefficient alloy and for a coupling (bent pipe 6, branch pipe 7) or an apparatus (valve 2 or others) made of stainless-steel pipe, and this low-thermal-expansion- coefficient alloy made piping is welded with this extension straight pipe portion 3. The length L (mm) of the straight pipe portion 3 is longer than 0.6 (R×t) , where R is outer radius (mm) of the extension straight pipe portion, and (t) is its thickness (mm). Because different material welding is a welding between the straight pipes, thermal stress distribution can be predicted and stress analysis and piping design become easy.

摘要： PROBLEM TO BE SOLVED: To constitute a carrier pipe without having any loop pipe or suppressing the number of loop pipes as less as possible by forming the carrier pipe of a low thermal expansion part composed of Fe-Ni based low thermal expansion coefficient alloy. SOLUTION: A pipe 1 carrying extremely low temperature liquefied gas is constituted of a low thermal expansion part formed of Fe-Ni based low thermal expansion coefficient alloy called invar alloy. The thermal expansion coefficient of the Fe-Ni based low thermal expansion coefficient alloy is approximately 1/10 compared with austenite based stainless steel used for a conventional pipe and the deformation of the carrier pipe formed of using the invar alloy caused by the expansion/contraction can be extremely minimized compared with the conventional pipe so that, when the both ends of the pipe 1 are fixed without providing any loop pipe, the thermal stress generated in the pipe 1 never exceeds the tolerable stress. This constitution can eliminate an overhang part in a part from one end 2 to the other end 3.

摘要： PROBLEM TO BE SOLVED: To effectively suppress the occurrence of thermal stress in the case of slow cooling on operating a heat exchanger when started or the like by scattering a low-temperature liquid in an inlet chamber at a smaller flow rate than that when normally operated, when cooled slowly. SOLUTION: First, when started, an LNG is supplied at a smaller flow rate (smaller flow rate than that when normally operated) to an inlet chamber 22. This LNG is distributed from a master portion of an LNG supply unit for slow cooling to respective scattering portions 36, and scattered from the portions 36 toward a tube plate 25 in a wide area. Accordingly, according to this slow cooling method, local cooling due to preceding only at a lower portion of the chamber 22 like a conventional slow cooling method is not almost executed, but the chamber 22 is substantially easily uniformly cooled in an overall vertical area. Thus, a thermal stress generated at a member for forming the chamber 22 is effectively alleviated, and hence a fatigue fracture of a welded portion due to the thermal stress caused by this temperature difference can be more effectively prevented.

摘要： PROBLEM TO BE SOLVED: To provide a turbine device which can improve turbine output, while inhibiting oscillation of a fluid exhaust passage, and a cold energy power generation system which can improve power generation output, while inhibiting oscillation of the fluid exhaust passage.SOLUTION: The turbine device T includes a turbine 3 to which a fluid supply passage 1 to which drive fluid NG is supplied and the fluid exhaust passage 2 from which the drive fluid NG is exhausted are connected. In the turbine device T, a turn-inhibition passage R is provided which supplies turn-inhibition fluid to the fluid exhaust passage 2 so as to inhibit turning of the drive fluid NG flowing under a turning condition in the fluid exhaust passage 2. The turn-inhibition passage R is constructed of a bypass passage 4 which takes out part of the drive fluid NG from the fluid supply passage 1 as the turn-inhibition fluid to make it bypass the turbine 3 to supply it to the fluid exhaust passage 2.

摘要： PURPOSE:To perform stable temperature control by changing either one or both of the flow of the heat source fluid of a vaporizer and a gasification liquid, keeping the pressure or temperature of an intermediate heat medium constant, and holding the cooled state of the portion required to be kept cooled. CONSTITUTION:A pressure detection section 12 for detecting the pressure of an intermediate heat medium on a vaporizer 1 is provided on it, the opening of an auxiliary control valve 8a is regulated by a command from the detection section 12, and the flow of a gasification liquid is controlled so that the pressure of the intermediate heat medium is kept constant. The intermediate heat medium quickly responds to the balance between the heating by a heat source fluid and the cooling by the gasification liquid, thus resulting in the pressure change, i.e., temperature change, when it is used for the control subject, the control delay can be shortened from 10min to about 0.5min, for example. The pressure of the intermediate heat medium may be kept constant by the flow control of both the gasification liquid and the heat source fluid.
