NFPA 13 Seismic Bracing Requirements: Cable Sway Braces
https://blog.qrfs.com/320-nfpa-13-seismic-bracing-requirements/
Seismic braces guard against this by tightly securing pipe to structural members, protecting against lateral (perpendicular to the run of the pipe) and longitudinal (parallel to the run of the pipe) shaking. The fundamental job of seismic braces is to resist the seismic load a system will experience during an earthquake.

Longitudinal Force = Pipe Wt. per foot x Longitudinal Brace Spacing x 0.5 See pages 3-3 and 3-4 for allowable design forces. Revise spacing of braces if necessary. 9. Check trapeze member for combined vertical and lateral seismic loads using the following interaction equation: (Revise trapeze spacing or brace if necessary). 10.
Longitudinal Seismic Bracing Options for CPVC?
https://www.meyerfire.com/daily/longitudinal-seismic-bracing-for-cpvc
As best I can tell there's no listed bracing method for longitudinal seismic bracing for CPVC. Traditionally we've addressed this by placing a tee with a short pipe stub perpendicular to a main and braced that perpendicular pipe with a "lateral" brace, which acts longitudinally on the main. The downside to this is that it's not concentric to the main, but it's pretty close.

brace per NFPA 13-9.3.5.5.8. A conservative longitudinal sway bracing solution is shown in Figure 1. 1. Install T in main piping with the outlet the same size as the main. 2. Install a short nipple in the side outlet with a cap. 3. Install lateral sway brace on outlet nipple at closest possible dimension relative to the main piping.
