摘要： A laser irradiating torch device is used to apply corrosion resistant coating or other coatings to an inner surface of small diameter piping. The torch device consists basically of a torch body disposed in the rearward end of the torch device; a revolving torch head disposed in the forward end of the torch device which revolves around the central axis of the torch device; and a driving device to rotate the torch head disposed in the rearward end. A laser beam generated outside the torch device is transmitted to the torch head in an optical fiber disposed, longitudinally through the central axis, and the focal point of the laser beam can be adjusted with a lens system whose location can be adjusted in the axial direction. The transmitted laser beam is reflected radially out of the torch device with a reflection mirror, and the lens system is adjusted so that the laser beam is focused near the inner surface of the piping. When the torch device is inserted in the piping, a centering device aligns the torch body and the torch head centrally within the piping so that the revolving axis of the torch device coincides with the central axis of the piping. When the torch head is rotated and the laser beam turned on, the inner wall surfaces of the piping is heated uniformly to produce a coating of excellent consistency, thus producing a coating having superior corrosion resistant properties.
摘要翻译：使用激光照射割炬装置将耐腐蚀涂层或其他涂层施加到小直径管道的内表面。火炬装置基本上由设置在割炬装置的后端中的割炬本体组成; 设置在割炬装置的前端周围围绕火炬装置的中心轴线旋转的旋转炬头; 以及用于旋转设置在后端的割炬头的驱动装置。在割炬装置外部产生的激光束以纵向穿过中心轴设置的光纤传输到炬头，并且激光束的焦点可以利用其位置可以在轴向上调节的透镜系统来调节。发射的激光束用反射镜径向地反射到割炬装置之外，并且调整透镜系统，使得激光束聚焦在管道的内表面附近。当割炬装置插入管道时，定心装置将管炬主体和割炬头对齐在管道内，使得割炬装置的旋转轴线与管道的中心轴线重合。当割炬头旋转并且激光束打开时，管道的内壁表面被均匀地加热以产生优异的稠度的涂层，从而产生具有优异的耐腐蚀性能的涂层。

摘要： A method of enhancing residual compressive stress in a horizontal double metallic pipe which includes an outer pipe and an inner pipe fitted into the outer pipe. Cooling water is introduced into both the inner pipe and an annular space defined between the inner pipe and the outer pipe. Further, cooling water is injected into the annular space to form a partial cooling water flow through the cooling water in the annular space. During the injection of cooling water, the outer pipe is heated from the outside thereof to generate a temperature difference between inner and outer faces of the outer pipe to such a degree that thermal stress larger than a yield point is produced in the outer pipe. Then, the heating of the outer pipe is stopped to allow the outer pipe to stand, whereby residual compressive stress is provided to a radially inner portion of the outer pipe.

摘要： The corrosion resistance inherent in stainless steel is further improved by a cladding layer provided on the surface thereof. The cladding layer is formed of a coating material which is applied onto the surface of the stainless steel and, then, burnt to be fused by laser beams. The coating material contains a larger amount of Cr than that of the stainless steel. The thus fused material and a fused portion of the stainless steel are mixed with each other to form the cladding layer of remarkable corrosion resistance due to a larger amount of Cr contained therein. The formation of the cladding layer on the inner surface of a small diameter pipe is enabled by a coating film shaping device which has a jig for shaping the applied material into a film of a uniform thickness and by a laser irradiation torch which has an arrangement for emitting the laser means radially outward from the inside of the pipe.
