Problem with the unloading crane hose!
Thread Content
Article 6.4.2 of the \"Code for Fire Protection Design of Petrochemical Enterprises\" GB 50160-2008 (2018 edition) states that \"for loading liquids of Class A1, B, and C1, submersible loading nozzles shall be used.\" Compared with the previous version of the code, the requirement regarding unloading nozzles has been removed; does this mean that certain specific types of materials require the use of nozzles during unloading, while other materials do not need such nozzles?
For print books, this entry is “loading and unloading”; please verify again
Thank you! The revised text mentions a loading crane pipe, while the official standards refer to loading and unloading equipment!
Later, a corrigendum was published in the print version as well; it can be found here: http://www.jhpress.com/View/News/NewsView.aspx?id=26
As the original poster said, are there certain types of media for which dip pipes are used during unloading, while other media do not require such dip pipes?
