Heat Tracing / Insulating Seismic Separation Assembly 2

[sl3656]

Has anyone had any experience heat tracing / insulating a seismic separation assembly, per NFPA 13-2019 Figure A18.3(a)?

We have a 6-inch fire service line that runs across a building seismic / expansion joint that is currently insulated with 2-inch fiberglass / heat-traced. UL/FM-listed product recommendations that address this specific installation scenario are appreciated, if you know any! Thanks.

Raytheon is about the only one I know of.
It shows standpipes. Not sure why it would not work on Seismic Loop..

Appleton Electric - Emmerson also manufacturers a heat trace system for fire protection piping.
