PURPOSE:To reduce the number of parts to be disassembled on exchange of breakage plates and reduce the exposed amount of radiation for an operator durig the exchanging work for the breakage plates under the high radiation amount, by using flanges also as the holder for a breakage plate as the supporting structure for the breakage plate. CONSTITUTION:A breakage plate 1 is interposed between a male flange 16 and a female flange 17 which are installed onto a piping 15, and an O-ring 19 is inserted into the collar part of a piping 18 equipped with a collar by a transferring flange 20. A metal sheet 21 is inserted between the undersurface of the transferring flange 20 and the upper surface of the female flange 17. The breakage plate 1, metal sheet 21, and the O-ring 19 are tightened at once by a nut 8 and a through bolt 7 which penetrates the male flange 16, female holder 17, and the transferring flange 20. |
