Chlorine Gas — Equipment Material Selection Data

Name: Chlorine Gas Equipment Material Selection Dataset
Creator: James Riggins

Direct answer: This page collects every published row in the LibertyCES datasets that applies to chlorine gas service: elastomer seal compatibility, centrifugal pump material resistance, hydrometallurgical duty-class selection, engineering rules. The Flowline compatibility chart does not list chlorine, and the peristaltic-tube dataset has no chlorine entry. The pump dataset publishes liquid chlorine only (no gas-phase row), so that row is shown labeled as liquid for reference. Seal rows are the dataset's own chlorine entries, listed by their exact names. LibertyCES supplies the equipment for handling these fluids, never the fluid itself.

Chlorine Gas Monel Hastelloy Vented Ball Valve

AVCO Valve's dedicated chlorine service ball valve complies with Chlorine Institute Pamphlet 6, appropriate for Chlorine Service Classes I & IV - a real, named industry chlorine-handling standard. Configuration: carbon steel (WCB) body/ends with ball, stem, and retainers in Monel 400 or Hastelloy C (full-Monel or full-Hastelloy also offered for further internal corrosion protection); the ball is vented to provide pressure relief during operation, the same off-gassing/pressure-relief engineering pattern already established for sodium hypochlorite service (Hayward TBH Z-Ball, Richter GU/GUT overflow valves) but applied here to chlorine gas/liquid specifically. B7 body bolts and 2H nuts for added strength. Available as the 1100 Series platform (full port, minimal pressure drop) or 1900 Series platform (V-ball, Cv-selected) when throttling control is needed.

Confidence: single-vendor. Source: data/vendor-sources/avco-valve-chemical-processing.md.

Ald Diaphragm Chlorine Nitric Acid Limits Heap Leaching

Netafim's Mining Products catalog publishes a real chemical resistance chart for ALD70, the diaphragm material used across its 75/90/100 Series valves in heap-leaching service (the 'MIN' mining configuration). Several named chemicals rate flatly 'Not Good' regardless of concentration or temperature: nitric acid (not good even at 10%), chlorine dioxide, and chlorine gas. Sulfuric acid - the primary heap-leaching lixiviant for copper/uranium/nickel extraction per this same catalog's own process diagram (Cu2O3 + H2SO4 -> Cu2(SO4)3 + H2O) - is rated only to 38C max, a notably more restrictive limit than this project's existing sulfuric acid guidance which centers on PVDF/PTFE/FEP/PFA tank and pipe materials surviving to much higher temperatures at high concentration. This is a real, actionable reminder that a valve's diaphragm elastomer can be the limiting material in a system even when the body/liner material handles the chemical fine at higher temperature - relevant to any heap-leaching, gold/silver cyanide, or chlorine-based quote using this valve family. Netafim's own catalog identifies the fix: components can be ordered in Hastelloy instead, explicitly because Hastelloy 'is resistant against chlorine gas, hypochlorite and chlorine dioxide solutions' and has 'excellent resistance against concentrated solutions of oxidizing salts (such as iron III and copper chloride).'

Confidence: confirmed. Source: data/vendor-sources/netafim-mining-heap-leaching.md.

Equipment LibertyCES Supplies

LibertyCES specifies and supplies the pumps, valves, tanks, piping, and instrumentation that store, transfer, meter, and contain fluids like chlorine gas — never the fluid itself, always the equipment engineered to handle it.

Frequently Asked Questions

Does LibertyCES sell chlorine gas?

No. LibertyCES supplies the equipment that stores, transfers, meters, and controls fluids like chlorine gas (pumps, valves, tanks, piping, instrumentation). It does not supply the fluid itself.

Which engineering rules apply to chlorine gas service?

Published rules on this page: Chlorine Gas Monel Hastelloy Vented Ball Valve; Ald Diaphragm Chlorine Nitric Acid Limits Heap Leaching. Each links to its full rule page with confidence rating and source.

Is this data a final material approval for chlorine gas?

No. It is a screening reference compiled from published vendor data and LibertyCES field rules. Ratings depend on concentration and temperature; confirm against the manufacturer data sheet and your actual duty point, or request a free spec review.
