摘要： PROBLEM TO BE SOLVED: To obtain a lining layer to the vessel inside inexpensive, and having acid resistance and abrasion resistance.
SOLUTION: While moving a rotary Hume pipe 1 in its vessel axis direction, aggregate b and molten sulfur c are supplied to the vessel 1 inside to mix these by the rotation, and the mixture is subjected to lining a to the vessel inside using the molten sulfur c as a binder of the aggregate b. The recycling of sulfur or the like refined by desulfurization of petroleum and natural gas which are not conventionally sufficiently recycled is facilitated. Using the sulfur, a sulfur-possessed acid-resistant and abrasion-resistant vessel 1 of lining to the vessel inside can be obtained at a low cost. If the vessel 1 employs a hardly deformable vessel by strength in a diameter direction such as ductile cast iron and the Hume pipe, due to its resistance to deformation, the above-described performance can be obtained for a long period of time even in sulfur mixture lining a without toughness.

摘要翻译：要解决的问题：为了在容器内部获得廉价的并具有耐酸性和耐磨性的内衬层。
解决方案：在旋转休谟管1沿其容器轴线方向移动时，将聚集体b和熔融硫c供应到容器1内部以通过旋转进行混合，并将混合物经受衬里a到容器内部使用熔融硫磺作为聚集体b的粘合剂。通过不常规地充分再循环的石油和天然气的脱硫来精炼的硫等的再循环便利。使用硫，可以以低成本获得含硫耐酸耐磨损容器1的衬里到容器内部。如果容器1由于其耐变形性而在诸如球墨铸铁和休斯管之类的直径方向上采用几何变形的容器，所以即使在硫混合物中也可以长期获得上述性能衬里没有韧性。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To simultaneously mask an aperture by closing the aperture with a masking member fitting into the aperture of a special shaped tube, etc., and engaging an engaging member with the inside wall of the aperture of the special shaped tube by the projection thereof to a lateral side. SOLUTION: At the time of hoisting the special shaped tube, etc., by a coating jig 1, the masking member 3 is first pressed into the aperture of the special shaped tube. When a cylindrical part 2 is further pushed downward, the cylindrical part 2 moves downward against a coil spring 6 and, therefore, the spiral surface 15a of an upper spiral member 15 comes into contact with the spiral surface 10a of a lower spiral member 10 and the upper spiral member 15 is rotated around its axis. As a result, a connecting member 25 rotates around a shaft 27 and the engaging member 35 projects in the radial direction of the cylindrical part 2. When the force to downwardly press the cylindrical part 2 is released, the cylindrical part 2 moves upward and is fixed to an upper home position while the cylindrical part rotates further along the spiral surface 15a. A hanger 40 is hooked in this state to a hook, etc., and is hoisted and the external surface coating of the special shaped tube is carried out.

摘要： PROBLEM TO BE SOLVED: To further improve corrosion resistance of an external surface spray coated pipe which is made of cast iron or steel and has a corrosion preventive layer of Zn-Al pseudo alloy on an external surface.SOLUTION: A corrosion preventive layer formed on an external surface of a pipe by metal spray coating is made of a pseudo alloy layer which is a mixture of a zinc layer and an aluminum alloy layer containing magnesium and silicon. This lowers the potential of an external surface spray coated pipe in a corrosive environment compared to one having a conventional corrosion preventive layer of which aluminum alloy forming the pseudo alloy layer does not contain magnesium. As a result, a sacrificial anode effect is increased to increase corrosion resistance of the pipe, extending corrosion-resistant life.
摘要翻译：要解决的问题：进一步提高由铸铁或钢制成的外表面喷涂管的耐腐蚀性，并且在外表面上具有Zn-Al假合金的防腐蚀层。解决方案：在通过金属喷涂的管的外表面由作为锌层和含有镁和硅的铝合金层的混合物的假合金层制成。与具有形成假合金层的铝合金不含镁的常规防腐层的情况相比，这降低了外部表面喷涂管在腐蚀性环境中的潜力。因此，牺牲阳极效应增加，以增加管道的耐腐蚀性，延长耐腐蚀寿命。

摘要： PROBLEM TO BE SOLVED: To exhibit excellent corrosion preventing effect and to prevent corrosion even in an environment where there is many underground water and the buried pipe easily corrodes and to enhance the corrosion preventing effect of the outer face of the buried pipe.SOLUTION: A belt-like stretch film is wound around the outer face of a casting iron pipe to be buried while applying tension. Thereby, a covering layer constituted by superposing a thin plastic film is formed onto the outer face of the buried pipe. The covering layer is formed closer to the pipe with less gap with the pipe outer face by the film stretching even in a part where the outer shape is complicated such as a joint part, not only the adhesion of the film and the pipe but also the adhesion of films themselves are accelerated by the shrinkage force of the films, the intrusion of the underground water from between the films constituting layers is prevented, thereby corrosion preventing effect can be enhanced.

摘要： PROBLEM TO BE SOLVED: To scarcely generate dew condensation in a heated object in powder coating.
SOLUTION: In a powder coating method, a metal-made heated object is heated in a combustion type-hot blast heating furnace and powder coating is performed on a surface of the heated object, wherein the heated object is heated by a pre-heating means without the combustion of a fuel before the heated object is heated in the combustion type-hot blast heating furnace, the maximum heating temperature of the heated object with the pre-heating means is set lower than that with the combustion type-hot blast heating furnace, this scarcely allows the condensation to be generated in the heated object since any fuel is not combusted in the pre-heating, and further, the generation of dew condensation is suppressed even in the combustion type-hot blast heating furnace since the temperature of the heated object is increased with the pre-heating.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of coating defects that are caused when a powder floating around a powder nozzle adheres to the nozzle, or the like, to become a molten drop at the time of the application of powder coating to the inner surface of a pipe. SOLUTION: A powder coating apparatus is formed into an integrated triple structure by a sheath pipe 3 covering a part of the rear portion of a powder nozzle 1 or the whole of a lance 2, and an annular space formed by the inner peripheral surface 31 of the sheath pipe 3 and the outer peripheral surface of an outer pipe 22 of the lance 2 is set to a reflux circuit 23 communicating with a suction device 4 generating air streams in the direction reverse to the feed direction of powder paint P. Adhering paint or floating powder paint ready to adhere is always removed by air streams in the direction always sucking air around the powder nozzle. If a structure making the axial line C1 of the lance 2 eccentric downwardly with respect to the axial line Cs of the sheath pipe 3 is set, the excessive flow of air under the powder nozzle is suppressed even in a suction state not only to minimize the influence on a coating pattern but also to obtain balance enhancing the removal effect on adhering paint.
