Double Containment Piping — Metal Plating & Photographic Process Solutions
Named chemicals
What LibertyCES's vendor documentation shows
The strongest plating-bath evidence in the corpus, and real field data rather than a compatibility table. Four UTC Goodrich Cleveland installations from 2013 are documented: 30-37% chromic acid with 35% sulfuric acid; a 7-9% sodium cyanide + 2% sodium hydroxide + 3% cadmium oxide + 6% sodium carbonate mixture; 25% nickel sulfate; and contaminated groundwater remediation. That cyanide/cadmium/caustic/carbonate mixture is an actual plating-bath waste stream, confirming Chem Prolok double-wall containment for the cyanide-bearing waste itself rather than only the treatment instrumentation. Broader pattern: of the 26 documented installations at least 9 explicitly replaced failed or leaking PVC or CPVC.
Materials documented for this service
- Advanced PE PE445584C / PAS 1075
- PP, PVDF, ECTFE (Duo-Pro)
- Simultaneous butt fusion only for double-wall (primary + secondary fused in one operation)
- Explicit vendor installation rule: threaded joints should not be allowed

Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
FAQ
Is Double Containment Piping compatible with Metal Plating & Photographic Process Solutions?
The strongest plating-bath evidence in the corpus, and real field data rather than a compatibility table. Four UTC Goodrich Cleveland installations from 2013 are documented: 30-37% chromic acid with 35% sulfuric acid; a 7-9% sodium cyanide + 2% sodium hydroxide + 3% cadmium oxide + 6% sodium carbonate mixture; 25% nickel sulfate; and contaminated groundwater remediation.
