压力管道中介质毒性的判别

Discrimination of Medium Toxicity in Pressure Pipes

化工行业中遇到的毒性介质较多,目前关于介质毒性的分级也有多个标准,且各标准之间略有差异,在不同的使用场所需考虑介质毒性的差异性,对介质毒性分级的相关规范进行了研究,并对压力管道中介质毒性的分级进行了分析。

There are many toxic mediators in chemical industry.At present,there are also many standards on the classification of medium toxicity,and there are some differences between the standards.The difference of the toxicity of medium is considered in different use places.In this paper,the related norms of the medium toxicity classification are studied,and the classification of the medium toxicity in the pressure pipeline is analyzed.
