Are there any requirements regarding the drawing scale for plumbing and drainage drawings? Must it be 1:100, or the same as the scale on the architectural drawings?
There’s no need to; choose based on your requirements regarding the text on the drawings, the layout of the prints, etc. The goal is to achieve drawings that are beautiful and clear
Generally, a 1:1 scale is sufficient; the axonometric views of water supply and drainage systems as well as the diagrams of external pipes do not need to be drawn to scale
Is the image a bit too large at 1:1?
National standards have relevant provisions; for details, refer to the Standards for Drawing of Water Supply and Drainage Systems GBT 50106-2001. This post was last edited by li*ch1968 on 2009-3-17 at 09:53.]
For ordinary drawings, especially those related to water treatment, it is sufficient as long as they are clear and accurately labeled; however, for blueprints, compliance with the plumbing drawing standards GBT 50106-2001 is mandatory. The drawings produced by design institutes are all made in accordance with national standards, while environmental protection companies basically do not follow these standards.
