好像industrial 很少用管子吧，即使是一根电缆，你可以用3寸的tray， 多的可以用4或6寸（浅的）的，更多的可以用深的6寸的。

Please be aware :
, c4 s% G0 J0 S0 S' ?4 c1. In order to reach the instruments which are above the Grid Floor A ,see F1 above, cables coming from the Branch Tray C have to pass the Grid Floor A.
2. If using basket tray to conduct cables, you have to make a hole at the Grid Floor A by cutting a piece of stuff from the Grid Floor A. then the basket trays can go through the Grid Floor A.
$ N4 J/ b  \' A3. IF using a pipe to conduct cables, because the size of the pip is one inch you can make a small hole at the Grid Floor A by a iron bar(撬棍)
$ b2 r! }2 H; m9 T/ j# s4. While you finish one hole for the tray, you can finish 10 holes for the pipe with the same time.
  ]) G. Q, b% C2 J2 m So to make job easy and fast I prefer to use more pipes.
As shown on F2, see the Ins A.  If x or y is >18 inches I cut a hole for the tray.
6 K% p) o8 L' y$ _) }5 W4 X The distance of 18 inches is mandatory by SHELL.
) K; n5 p+ N$ \In this case about 85% instruments above the Grid Floor A have been serviced by pipes.
