摘要： PROBLEM TO BE SOLVED: To prevent the corrosion of an outside surface side, to additionally suppress the occurrence of cracking and to determine the components of a welding material adequate for the suppression thereof. SOLUTION: The coating material is used for forming a coating layer 5 for coating a substrate 2 which is effectively cooled on its inside surface side. The mass% of the material is 0.06 to 0.13 C, 20 to 26 Cr, 0.3 to 1.0 Si, 0.8 to 1.2 Nb, ≤0.5 Ni. The Cr of the known coating layer is hitherto adequately 23 to 30 mass% but a decrease of mass% of the Cr is possible under the positive cooling environment. The range of mass% of the Cr is shifted to a side where the range is smaller than known mass%. The Cr is added in both points of corrosion resistance and the improvement of high-temperature strength. If the amount thereof is too much, toughness is deteriorated and if the amount is too little, the effect of the corrosion prevention is low. The mass% of the Cr can be made lower than 26% by cooling and as a result thereof, the deterioration in the toughness can be prevented. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To detect the inside local corrosion of a pipe with high accuracy by making a cold or hot medium to flow through the pipe or enclosing the medium in the pipe and detecting the temperature difference between a thin part and normal part from the external surface side of the pipe by using thermography. CONSTITUTION:A local thin part 2 may be formed on the internal surface of a furnace- wall pipe 1, etc., due to acid corrosion or caustic corrosion. When the pipe is filled up with a hot or cold medium, for example, hot water to detect the thin part 2, a temperature distribution is formed on the external surface of the pipe in accordance with the various thicknesses t0, t1, t2,... of the pipe and isothermal lines are formed in a plane. The isothermal lines are nondestructively observed from the external surface by using thermography. As a result, the thin part 2 can be detected, because a pattern 5 of a color tone which is different from that of the peripheral normal part is seen along the isothermal lines. Even when oxide scales are formed the internal and external surfaces of the pipe, the part 2 can be detected without hindrance when the scales are uniformly formed. Therefore, the inside local corrosion of the pipe can be safely and accurately detected in a short time over a wide extent without requiring any pre-treatment, such as the descaling, etc.

摘要： PROBLEM TO BE SOLVED: To increase a heat transfer surface for a supporting load and cause a spray inner pipe as well as spray nozzle to be sufficiently supported by a method wherein at least one of the spray nozzle and the spray inner pipe is supported by applying a plurality of supporting devices from its circumference. SOLUTION: A supporting device 50 is inserted into a threaded hole 9 of a main body 1 of a device for reducing a superheated state under a condition in which a middle rod 11 is threaded into a supporting fitting 10 with its front end surface being surface contacted to an outer circumferential surface of the spray nozzle and the middle rod 11 being inserted into a hollow bolt 12. After the hollow bolt 12 is threaded into and set at the hollow bolt, a seal cap 13 is applied on it, both a connecting part 14 between the main body 1 of the device for reducing the superheated state and the hollow bolt 12 and another connecting part 15 between the hollow bolt 12 and the seal cap 13 are sealingly welded. According to this supporting device 50, a positive transfer of load for making a surface contact of the supporting section is attained and the hollow bolt 12 is uniformly fastened, thereby the supporting section is forcedly supported and centering of the device at the time of setting is facilitated.
