【《日本原子》1983年第10期第21页报道】自从出现了沸水堆应力腐蚀问题后,日本已研究出一系列措施来对付由下面三种原因引起的应力腐蚀;1)材料敏化;2)张应力;3)环境条件。防止应力腐蚀基本方法和实用措施见图。抗腐蚀包层法(CRC):将高抗应力腐蚀的低碳焊接金属铺焊在管子内表面的易被对缝焊接产生热敏化的区域,以使该区域得到适当的保护。 【Japan Atomic Energy】 Issue 10, 1983 Page 21 Since the issue of stress corrosion in boiling water reactors, Japan has developed a series of measures to deal with stress corrosion caused by the following three causes: 1) sensitization of materials; 2) tensile stress; 3) environmental conditions. To prevent the basic method of stress corrosion and practical measures shown. Corrosion Resistant Cladding (CRC): Low-carbon, high-stress-corrosion resistant weld metal is applied to areas of the pipe inner surface that are susceptible to heat-sealant welding to provide proper protection in this area.
