2012, Professional Course Day 1, 6:9 p.m., regarding valves
Thread Content
What requirements must be met regarding the installation of valves and accessories on the inlet and outlet pipes of liquefied petroleum gas compressors? A Valves should be installed at the inlet and outlet. B A filter should be installed at the inlet. C A check valve and a safety valve should be installed at the outlet. D A bypass pipe and a bypass valve should be installed between the inlet and outlet pipes. Intuitively, all of ABCD are correct. I would like to ask if there is a specific source for this question? I don’t know which standard many of these questions come from.
Your feeling is correct; ABCD are all right. For this question, you can refer to the green book
Your feeling is correct; ABCD are all right. This question primarily examines the design of pressure pipelines; you can refer to the green book, the original text.

Thank you so much! What is a green book? The association’s book?
It’s not from an association; it’s a training manual for national pressure pipeline design approvers. You can search for such resources on forums
I’ve checked this; it can be found in GB50156. B and C are definitely correct, as for A, I’m not sure if it’s necessary – is there any requirement to include it?
