挽救，再制造和修复的控制阀的完整性

2006年7月/8月的IJ发行，其中包含第1部分，内容涉及挽救，再制造和修复的控制阀的完整性。第二部分包括有关直接有效的识别，减排以及对潜在不兼容控制阀的持续的组织意识的建议。为了为第2部分的场景为那些可能没有看过第1部分或不记得的人设置场景，本文的引言部分重申了第1部分的基本元素。

介绍

Depending on equipment age, repair history, application severity and other factors, salvaged/refurbished (aka “remanufactured”) or repaired control valves may no longer meet a manufacturer’s original specifications as designed in accordance with the ANSI/ASME B16.34 control valve standard,“Valves – Flanged, Threaded, and Welding End”.(1)

这是目前为控制阀编写的唯一可用的ANSI/ASME标准；但是，其范围覆盖了“新”阀。Thus, in the absence of a Standard for “used” control valves (i.e. to include salvaged/refurbished, remanufactured, or repaired) the issue of ensuring sustained integrity, through valve refurbishment to the manufacturer’s design specifications as developed in accordance with the ASME standard, may be overlooked.
