摘要： PURPOSE:To provide Ni or Mo coating on the surface of heat resistance alloy base material to improve anti-corrosion property of reactor structure material under the high temperature oxidation atmosphere. CONSTITUTION:The surface of heat resistance alloy base material 1' is coated by Ni, or Mo coated layers 4 and 5 with the specified thickness. For coating layer 2 with Ni, the undercoat layer 3 is provided between them to improve adhesive property between the base 1' and Ni layer 4. The best anti-corrosion effect is obtained when the thickness of coated layer is 300-800mu for Ni, 50-300mu for Mo, preventing from the crack generation of layers.

摘要： PURPOSE:To increase the contact area of both internal and external tubes and to improve the heat conductivity of the heat transfer tube by constituting the heat transfer tube of an internal tube, an external tube, a brazing material layer between both internal and external tubes, successively subjecting the external tube to annular heating and cooling processing, from its one end to another end, contracting the diameter of the external tube, and press-fitting the external tube to the side of the internal tube. CONSTITUTION:The outer peripheral surface 3 of an internal tube 2 is covered with a wearproof external tube 4, and the external tube 4 is contracted in its diameter and press-fitted to the side of the internal tube 2. The contraction of the diameter of the external tube 4 is performed in such manner that, firstly, the internal tube 2 pasted with silver wax 11 is inserted into the external tube 4, on the other hand, a heat transfer tube 1 is inserted into an annular thermal diameter contracting device 12, and any of the device 12 and the heat transfer tube 1 is moved axially. When annular heating and cooling processing is successively carried out from one end side to another end side of the heat transfer tube by a heating part 13 and both cooling parts 14 and 15, the processed parts are contracted in the diameter. Further, silver wax is molted at the heating time, and is buried into a gap 7 formed by depressions and projections due to surface roughness of the outer peripheral surface of the internal tube 3 and the inner peripheral surface 5 of the external tube 5. Silver wax is cooled by a cooler 15 and is solid and a brazing material layer 6 is formed between both internal and external tubes. Accordingly, the contact area of both internal and external tubes is increased and the heat conductivity is improved.

摘要： PURPOSE:To carry out a simple and secure corrosion protective treatment of fastening bolts and nuts of steel plates in the sea water. CONSTITUTION:Corrosion protective covers 4, 5 are forced to come in closely contact with the base metal 1 by a magnet ring 7 equipped at the flange 6 for jointing steel plates 1, 1 in order to fasten a couple of bolt and nut for these steel plates and coat the head 2' and the nut 2'' with a corrosion protective covers 4, 5. And a soft corrosive protective agent 17 is injected into a feed inlet hole 9 through a pass by a pump 14. The sea water in the inside is replaced to discharge it from a outlet hole 10 and to securely charge evenly the soft corrosive protective agent 17 into the periphery of the bolt and nut. Accordingly, it is not necessary to press coating like putty or brush it for corrosion protective, and the soft corrosive protective agent can be easily charged in the periphery of the bolt and nut via the corrosive protective cover. And further, after the soft corrosive protective agent is cured, it is removed to repeatedly reuse. And moreover, construction period can be reduced, working accuracy can be increased, and the cost can be reduced.

摘要： PURPOSE:To enable easy conveyance of slurrylike coarse solid powder, by adding a stabilizer to fluid to be treated. CONSTITUTION:Slurry (suspension) in an agitating tank 13 is fed through a hose 14 to a jet nozzle 10 of a water jet device. Simultaneously, high pressure water is fed through a hose 12 to the nozzle 10, and the slurry is injected at a high speed through the nozzle 10 toward a material 11 to be cut to cut the material 11 to be cut. In this case, a solid and water slurry composition consists mainly of solid powder (fine grain polishing material 21), e.g., aluminum, one or two or more stabilizers selected from a group consisting of alkali metallic salt of caboxymethylcellulose, hydroxyethylecellulose, polyacrylic sodium, and water. As a result, the slurry can be easily conveyed to the nozzle 10 without using a special forced feed device, and spent slurry is returned from a catcher 16 through a concentration control tank 18 to the agitating tank 13 for the reuse.

摘要： PURPOSE:To coat a surface to be coated in the water and/or its vicinity with excellent operability, by depositing a paint on the surface to be coated in the water and/or its vicinity, and simultaneously covering the coated film with a closely attached sheet material. CONSTITUTION:A paint 7 is supplied from a paint supply nozzle 6 and deposited on the surface 2 to be coated in the water and/or its vicinity, and the coated film 3 is simultaneously covered with the closely attached sheet material 4. As a result, the surface to be coated in the water and/or its vicinity can be coated with excellent operability. Since the paint is deposited on the surface to be coated and the coated film is simultaneously covered with the closely attached sheet material, the damage of the coated film immediately after coating by waves can be prevented. Besides, the diffusion of water, oxygen, etc., into the coated film can be prevented by the sheet material.
