相当于ASTM A182等级F91,经过改进的9Cr-Mo-V铸件材料的额定压力温度,目前还没有列在ANSI - 1996年版本中。

在升高的温度下,这种材料的允许应力值已经颁布在《ASME规程案例2192,1995年三月》中。

利用《规程案例2192》中的允许应力值,及ANSI ,附录F中介绍的方法,ASTM A217等级C12A的额定压力-温度的计算值以下表列出。

Pressure Temperature Ratings for modified 9Cr-Mo-V Cast Material equivalent to ASTM A182, GR. F91 are not currently listed in ANSI - 1996 version. Allowable stress values for this material at elevated temperatures were published in ASME Code Case 2192, March 1995. Using the allowable stress valves in Code Case 2192, and the methods outlined in ANSI , Annex F, the calculated values for Pressure-Temperature Ratings ASTM A217, GR. C12A are tabulated below.
ASTM A217等级C12A ASTM A217 GR. C12A
注意:(1) 仅适用于焊接端口阀门。

法兰端口额定温度最高为537o C. Notes: (1) For weld end valves only. Flanged end ratings terminate at
1000o F.

下列压力-温度表来自ANSI - 1996版,包括行业内最常用的阀体和阀帽材料。

所有阀门都适用于这些压力-温度表内某个特定的ANSI 压力等级和ASTM材料所显示的压力和温度范围内。

作为标准,阀门所进行的流体静力学壳体检测压力是ANSI额定压力等级的最大冷冲击工作压力的倍,流体静力学阀座检测压力是是ANSI额定压力等级的最大冷冲击工作压力的倍。

The following pressure-temperature charts are derived from ANSI - 1996 Version. It will cover the most commonly-used body and bonnet materials in the Industry. All Valves are designed to operate through pressure and temperature range shown in these P-T Charts for a particular ANSI Class Rating and ASTM Material. As a standard, Valves performs Hydrostatic Shell Testing at a minimum times and Hydrostatic Seat Testing at a minimum of times the
Maximum Cold Working Pressure of an ANSI Class Rating.
