Treatment of incoming cables for the installation of flameproof instrument equipment in chemical production
Thread Content
While browsing CNKI today, I came across an article titled \"Treatment of Input Cables for the Installation of Flameproof Instrumentation Equipment in Chemical Production.\" The topics discussed in it can provide explanations regarding the flameproofing requirements for instrumentation wiring in chemical plants, as required by various safety inspections today. See the attachment for details:
This article is rather chaotic in terms of explanation and formatting. There is more filler than essential content.
In many cases, it is very difficult to coordinate the mismatch between the cable outer diameter, the instrument connection port, and the sealing joints. For example, in a current project, the client has contracted six cable manufacturers, three seal joint manufacturers, and nine suppliers; yet the inner and outer diameters of the products from these suppliers all vary. What should be done? Depending on the various devices used, the winning combination may vary. . So there are many detailed rules that homeowners don’t understand; they shouldn’t get too involved in them. Give the rights to the design institute.
Great article, exactly what I needed. Thank you, OP.

There are explosion-proof instruments with explosion isolation certification, making it easy to meet all requirements regarding cable insertion. However, when using certain special instruments that lack explosion-proof certification in explosive environments and an explosion-proof box is required, it becomes difficult to handle the inlet pipe. Personal experience.
