美标的不锈钢管相关标准提交-ASTM A380-1999 不锈钢零件、设备和系统的清洗和除垢

 1.1 This practice covers recommendations and precautions for cleaning, descaling, and passivating of new stainless steel
parts, assemblies, equipment, and installed systems. These recommendations are presented as procedures for guidance
when it is recognized that for a particular service it is desired to remove surface contaminants that may impair the normal corrosion resistance, or result in the later contamination of the particular stainless steel grade, or cause product contamination. For certain exceptional applications, additional requirements which are not covered by this practice may be specified upon agreement between the manufacturer and the purchaser. Al- though they apply primarily to materials in the composition ranges  of the  austenitic, ferritic, and martensitic  stainless steels, the practices described may also be useful for cleaning other metals if due consideration is given to corrosion and possible metallurgical effects.
