摘要： PURPOSE:To provide an electric anticorrosion structure of the external surface of a tank bottom plate which enables the checking and securing of accurate electric energization. CONSTITUTION:A zinc plate 3 for anticorrosion is arranged at a specified position of the undersurface of a bottom plate 2 of a storage tank and a hole 4 for measuring potential is provided on at least one sheet thereof while a conduit 6 is laid to the outside of the tank bottom plate 2 from the hole 4 for measuring potential. A potential is measured at a specified position of the tank bottom plate 2 from outside a tank side wall 1 through an electrolyte packed into the conduit 6 thereby achieving a check of the electrolyte at an opening of the conduit 6 while securing electric energization.

摘要： PURPOSE:To solve the problems of the thermal properties and strength of a permanent reference electrode and to stabilize the potential by specifying the ratio among Zn, Pb and Sn in a Cu alloy used to form the electrode. CONSTITUTION:A permanent reference electrode is made of a Cu alloy consisting of 50-80% Cu, 0-50% Zn, 0-12% Pb and 0-12% Sn. The reference electrode has electrode potential close to that of a reference electrode of satd. calomel, satd. copper sulfate or silver chloride and is used to measure the potential of a metal present in an electrolyte such as cold or hot fresh water. When the reference electrode is used, high reliability of electrolytic protection of a hot water tank or the like can be ensured.

摘要： PURPOSE: To sharply reduce the measuring work by the self-potential method. CONSTITUTION: A small-diameter rod-like reference electrode 5 inserted into a hole 3 vertically bored on a concrete surface 1 by a drill and a doughnut type reference electrode 8 installed on the concrete surface 1 are assembled while the small-diameter rod-like reference electrode 5 is idly inserted into the hole 9 of the doughnut type reference electrode 8. A pressing elastic material such as a coil spring 6 is arranged between both electrodes 5, 8 to integrate them, and the correction potential value between both electrodes 5, 8 can be measured via a one-step operation.

摘要： PURPOSE: To allow a much significant effect to be shown as compared with a conventional method by surely holding plural metallic bodies in a superimposed state by adhesion so that electric conduction is ensured in the superimposing direction.
CONSTITUTION: An electrically conductive adhesive 11 is applied to both sides of foil 12 of a metal such as stainless steel, Al, Cu or Zn, and the adhesive 11 is coated with strippable paper 10 as a protector. A part of the bottom plate 9 of a seawater storage tank corresponding to the metallic foil 12 is polished, and the foil 12 is adhered to the polished part of the plate 9 with the adhesive 11 after stripping the paper 10. A corrosion preventing zinc plate 1 similar in shape to the foil 12 is then adhered to the foil 12 with the adhesive 11.

摘要： PURPOSE:To accurately measure the potential of a metal structure by using a potential current detector having a standard electrode of which outer circumference is covered with the same metal as that of the metal structure to be measured. CONSTITUTION:A potential current detector 1 has a standard electrode 10 of which outer circumference is covered with the same metal (e.g., Ti) 7 as that of a metal pipe to be measured (cooling water pipe) 8. This potential current detector 1 is used by being installed, to be freely installed, removed and replaced, to a flange 5 installed to a water chamber cover 4 composing a water chamber 3 of a condenser 2. This potential current detector 1 is at a distance of l from the nearest insoluble electrode 18 for supplying a corrosion-proof current, and detects the same potential and current of a cooling water pipe 8 which is at a distance lfrom the insoluble electrode 18 in the same water chamber. Based on the measured value of the potential current detector 1, it is arranged so that a corrosion-proof current at a proper potential can be supplied.
