Designation: G189 − 07 (Reapproved 2021)´1 Standard Guide for Laboratory Simulation of Corrosion Under Insulation1 This standard is issued under the fixed designation G189; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

2022年10月25日 · Scope1.1 This guide covers the simulation of corrosion underinsulation (CUI), including both general and localized attack,on insulated specimens cut from pipe sections exposed to acorrosive environment usually at elevated temperature.

2021年1月21日 · It describes a CUI exposure apparatus (hereinafter referred to as a CUI-Cell), preparation of specimens, simulation procedures for isothermal or cyclic temperature, or both, and wet/dry conditions, which are parameters that need to be monitored during the simulation and the classification of simulation type.

4 天之前 · 本文包含的装置和程序主要针对建立可接受的 CUI 模拟程序，以评估 CUI 环境对碳钢和低合金管钢的腐蚀性，并且也可能适用于其他材料。 然而，相同或类似的程序也可用于评估（1）其他金属或合金上的 CUI，（2）金属表面的防腐处理，以及（3）隔热及其成分对金属表面的潜在贡献。 崔。 唯一的要求是它们可以被机械加工、成型或并入本文所述的CUI单元管道构造中。 1.3 以英寸-磅为单位的数值应被视为标准值。 括号中给出的值是 SI 单位的数学转换，仅供 …
