Cable tray and pipe spacing requirements

1. When the cable tray is erected in parallel with various pipelines, the net distance shall meet the following requirements:

1. The cable tray is installed in parallel with the general process pipe (such as compressed air pipe) not less than 400 mm.

2. The cable reel and the corrosive liquid pipe should be installed in parallel at least 500 mm.

3. Cable reels should not be transported in parallel with corrosive liquids installed above or below corrosive gas pipelines. When unavoidable, it should not be less than 500 mm. And applied to the anti-corrosion board.

4. The cable tray is installed in parallel with the heat pipe. The heat pipe and the insulation layer are not less than 500 mm, and the heat insulation layer is not less than 1000 mm.

5, the cable tray should not be parallel to the upper heat pipe device, when the inevitable need is higher than the parallel installation of the heat pipe, not less than 1000 mm, measures should be taken for effective heat insulation.

2. When the cable tray crosses various pipelines, the net distance shall meet the following requirements:

1. It is not less than 300 mm with the general cable bridge cross process pipe.

2. The cable drum and corrosive liquid pipeline are lower than the cross or corrosive gas pipeline, not less than 500 mm. The length of the cable protection tray and cover plate should be not less than 2000 mm d for the intersection and stainless steel plate, because the pipe diameter (d ).

3, cable straddle bridges and heat pipes, heat pipes and insulation layers, not less than 500 mm, no insulation layer, should not be less than 1000 mm, and applications in the corner of the insulation board (such as asbestos board) cable protection tray and compartment The length of the hot plate should not be less than d 2000 mm. (d is the outer diameter of the heat pipe insulation)
