Can wooden supports be used for pipe supports in Class A workshops?
Thread Content
Dear sea friends, the pipe supports for the chilled water system in Workshop A of the company’s new workshop are made of wood, as shown in the image below. Is this in compliance with the regulations? The main beams and columns in the workshop have been treated for fire resistance. I feel it’s not appropriate for the construction team to use this type of wood for supports, but I can’t identify which regulations are being violated by this approach – are it the fire safety regulations for Class A workshops, or the regulations related to pipeline installation?
The conclusion on whether it can be used or not – what is the basis for that?
There’s no rule saying that wooden pallets can’t be used in explosion-proof workshops!
Thank you. So you mean it can be used, right? Are there any requirements regarding fire safety?
We use cold water and circulating water pipes in explosion-proof workshops frequently.
The wooden supports for the insulated pipes are treated; at least they should be anti-corrosion wooden supports. The ones in the photo don’t seem to be such ones :)
Yes, it seems that no anti-corrosion treatment has been applied. Which specific standard requires this?
Some project safety assessment experts, in accordance with 5.1-1 of GB50160, argue that non-combustible wood cannot be used for supports: the equipment itself (excluding linings) and its foundations, as well as pipes (excluding linings) along with their supports, hangers, and foundations, should be made of non-combustible materials; however, the cushion layer under the tank bottom can be made of asphalt sand； The wooden vibration dampeners that were commonly used in compressors in the past are no longer needed.
