OK thanks guys, unforntunately this had already been installed, I have had a converstion with project manager about why it was a code issue and it will be corrected using either a open raceway or metalic flex conduit.
Hello, one of our clients use Gas chromatographs, while installing one the manufacturer instructed us to us PVC schedule 80 4" as a sheath over the gas sampling line between the gas supply line and chromatagraph. Since we are not sending power through the conduit, except heat tracing, can we...
The power gas, which is natural gas thats been pressurized will be used in various processes at the site to drive, water pumps, oil pumps, produced fluids pumps, and even the crane. The power gas will not be used to purge the pressureized panel, since it is flamable.
What we are trying to do...
Thanks guys that what I was thinking. This is something the client requested, I've never heard of doing such a thing but I don't have the background in purged air systems, if it had been a new instalation I would have pushed for a new panel that is Class 1 Div 2 rated.
Just to clarify I'm not going to use "Power Gas" to pressurize the cabinet, I'm trying to seal the cabinet up so that it is Class 1 Div 2 rated, and doesn't need the air system to pressurize it.
No it is raw natural gas that has been pressurized that is used to drive pneumatic devices, very common in remote Natural Gas Compressor stations.
My plan was to put on conduit seals, seal up the cabinet, it should already be sealed except for the vent. It is in a classified area.
Hello everyone. I have a client who has a Natural Gas liquids facility at their compressor station. The control box for the NGL plant is a postive pressure box, fresh air is pumped in to prevent flammable gas from entering. They have decided to remove the air system and use power gas and to...
