Which standard should be used for drawing equipment layout diagrams?
Thread Content
HG20519.7-1992 is the standard for drawing equipment layout diagrams, while HG 20546.1-1992 specifies the content and level of detail required for the design of equipment layouts in chemical plants; I noticed that there are many similarities between the provisions of these two standards. Are both of these standards current ones? What is the relationship between them, and which one should be used when drawing equipment layout diagrams? Or either one will work. I hope someone who is experienced in design can give some advice
HG20519-1992 is the standard for drawing construction drawings in the field of process piping; it includes layout diagrams, flow charts, pipe diagrams, equipment lists, etc. HG20546.1-1992, on the other hand, specifies the content and level of detail required for equipment layout drawings. These two standards are compatible with each other and are both currently in use; you may use either one as needed
When arranging equipment, the first standard should be the main guide; when requirements specific to different stages arise, the provisions of the second standard should be referred to. In addition, it is necessary to learn more about safety and fire prevention regulations, as there are also certain professional requirements regarding equipment arrangement.
After reading the replies from those two, I gained new insights: HG20519-92 covers the contents and level of detail required in process construction drawings, while HG20519.7-92 explains how to draw equipment layout diagrams. HG 20546.1-1992, on the other hand, specifies the requirements for equipment layout diagrams. In my opinion, HG 20546-1992 should be referred to when creating equipment layouts, as it contains regulations specifically designed for such diagrams
Two standards, compatible with each other.
HG chemical standards are obsolete. HG was an industry standard established by the former Ministry of Chemical Industry under the State Council; this ministry was abolished in 2000, and the HG chemical standards were gradually phased out. Nowadays, few companies still use these HG standards.
