Selection of flexible hoses
Thread Content
I would like to ask the experts: when should bottom flexible hoses be used, when should top flexible hoses be used, and when should sealed flexible hoses be used?
Is what’s installed at the bottom also called a duckbill? No one installs it at the bottom, right? What about the remaining pipes?
It should refer to submersible loading nozzles; petrochemical regulations stipulate that for liquids of categories A B, and C A that are loaded in an open manner, submersible loading nozzles must be used
What was said upstairs is correct: according to petrochemical regulations, for liquids of categories A B and C A that are loaded in an open manner, submersible loading nozzles should be used, while for low-temperature liquids, sealed nozzles are necessary.
Hello, may I ask which standard pertains to the selection of flexible hoses?
