Specifying an alloy with an appropriate PREN ensures the protective passive oxide layer remains stable, preventing catastrophic tube wall perforation in stagnant zones.<\/p>\n<p data-path-to-node=\"18\"><b data-path-to-node=\"18\" data-index-in-node=\"0\">Q3: \u30c1\u30e5\u30fc\u30d6\u3084\u30c1\u30e5\u30fc\u30d6\u30b7\u30fc\u30c8\u306e\u7570\u7a2e\u91d1\u5c5e\u306e\u9078\u5b9a\u306b\u304a\u3044\u3066\u3001\u71b1\u81a8\u5f35\u306f\u3069\u306e\u3088\u3046\u306a\u5f79\u5272\u3092\u679c\u305f\u3057\u307e\u3059\u304b\uff1f<\/b><\/p>\n<p data-path-to-node=\"18\">A: \u71b1\u4ea4\u63db\u5668\u306b\u71b1\u30b5\u30a4\u30af\u30eb\u304c\u767a\u751f\u3059\u308b\u3068\u3001\u71b1\u81a8\u5f35\u4fc2\u6570 (CTE) \u306e\u7570\u306a\u308b\u6750\u6599\u306f\u3001\u7570\u306a\u308b\u901f\u5ea6\u3067\u81a8\u5f35\u30fb\u53ce\u7e2e\u3057\u307e\u3059\u3002\u3082\u3057\u30cb\u30c3\u30b1\u30eb\u5408\u91d1\u30c1\u30e5\u30fc\u30d6\u3092CTE\u30df\u30b9\u30de\u30c3\u30c1\u3092\u8003\u616e\u305b\u305a\u306b\u70ad\u7d20\u92fc\u30c1\u30e5\u30fc\u30d6\u30b7\u30fc\u30c8\u306b\u6eb6\u63a5\u3057\u305f\u5834\u5408\u3001\u305d\u306e\u7d50\u679c\u751f\u3058\u308b\u305b\u3093\u65ad\u5fdc\u529b\u306f\u3001\u5fc5\u7136\u7684\u306b\u6eb6\u63a5\u63a5\u5408\u90e8\u306b\u75b2\u52b4\u5272\u308c\u3092\u5f15\u304d\u8d77\u3053\u3057\u307e\u3059\u3002\u63a5\u5408\u90e8\u306e\u5b8c\u5168\u6027\u3092\u78ba\u4fdd\u3059\u308b\u305f\u3081\u306b\u306f\u3001CTE\u66f2\u7dda\u306e\u5fb9\u5e95\u7684\u306a\u5de5\u5b66\u7684\u89e3\u6790\u304c\u5fc5\u9808\u3067\u3042\u308b\u3002.<\/p>","protected":false},"excerpt":{"rendered":"<p>Operating under aggressive aqueous environments and elevated temperatures, tubular components face continuous metallurgical stress.
