Lethal Service Pressure Vessels for Chlorine Storage and Handling | Roben Manufacturing
Lethal Service Vessels for Chlorine Storage and Handling
Chlorine—essential for water disinfection and chemical manufacturing—is among the most widely used lethal substances requiring specialized pressure vessel containment. Chlorine storage and handling vessels must safely contain this dense, corrosive, toxic gas under various conditions from liquefied storage through vaporization and metering. The Chlorine Institute provides industry guidance complementing ASME lethal service requirements for these critical vessels serving water treatment, pulp bleaching, and chemical synthesis.
Application Importance
Chlorine enables safe drinking water for millions while supporting essential chemical manufacturing, but its toxicity demands extraordinary containment measures. Historical chlorine releases have caused mass casualties, making robust vessel design literally a life-or-death matter. Modern chlorine vessels incorporate multiple safety features beyond basic code requirements, including excess flow valves, seismic restraints, and containment buildings. Roben Manufacturing’s chlorine service experience ensures vessels meet both code requirements and industry best practices.

Frequently Asked Questions
What special requirements apply to chlorine storage and handling vessels?
Lethal service designation under ASME Code triggers mandatory 100% radiographic examination of all butt welds, post-weld heat treatment (with limited exceptions), impact testing when applicable, and enhanced documentation. Additional application-specific requirements may apply based on the substances handled and industry standards.
How does Roben ensure vessel integrity for lethal service?
Our quality systems exceed standard ASME requirements through enhanced material verification, certified welding procedures specific to lethal service, 100% radiographic examination with strict acceptance criteria, and comprehensive documentation. Every vessel undergoes hydrostatic testing and thorough final inspection before shipment.
What documentation does Roben provide?
We provide comprehensive documentation packages including ASME Data Reports, certified mill test reports, welding procedure specifications and PQRs, welder qualification records, NDE reports, hydrostatic test certificates, dimensional inspection records, and full material traceability documentation. Packages can be customized for specific regulatory requirements.
