Methods to Isolate Pipe Through a SCIF?

1/14/2025

I am a project manager currently building a SCIF in Northern Virginia. I was told by the landlord that we couldn't use Schedule 80 PVC for di-electric breaks as they have had a PVC break causing millions of dollars of damage prior. We don't like wrapping/grounding the pipe.

Have you run into this?

Do options exist, and what would you recommend to isolate through a SCIF?

1) It depends on the construction of the SCIF. There is many ways to construct such a space.

2) It depends on the specific authority on what they personally will approve.

3) It depends on the size of the sprinkler pipe that needs to penetrate the boundary.

You have already mentioned Northern Virginia such that location of the project is not another factor.

You will probably be forced into using the ground wire method.

Glenn:

You obviously have experience in this area. Where we stand today is our ec urity consultant is meeting with the gov, and will ask for their acceptance of wrapping and grounding the pipe. More to follow.

I did one once for Homeland Security. I used a dielectric fitting.

Copper or Stainless steel?

I would consider the use of this flange kit. It's mentioned in the other post but I have used it successfully as well at multiple locations.
