Engineering design of toxic and flammable gas detectors
Thread Content
Which type of qualified design firm can design the layout of toxic and flammable gas detectors in chemical plants and produce the corresponding drawings? What is this drawing generally called? Are the design requirements in line with those of GB/T 50493?
Either Class A or Class B qualifications are acceptable; the name of the drawing is Gas Detector Layout Diagram
Is there any place with clear regulations?
We have purchased this diagram; four copies are priced at 50,000 yuan, and it was produced by a Class A design institute. It’s not possible to estimate this price now

There is no specification requiring a layout plan for combustible and toxic gas detectors; it is described in the Manual for Automatic Control Design in the petrochemical industry, and in previous design projects the client indeed requested such a plan.
HG/T 20636.3-2017: Tasks for engineering design in the field of automatic control – This standard can be used as a reference.
