Lethal Service Pressure Vessels for Ethylene Oxide (EO) Systems | Roben Manufacturing
Lethal Service Vessels for Ethylene Oxide (EO) Systems
Ethylene oxide—a colorless gas used for medical device sterilization and chemical synthesis—presents dual hazards as both a lethal substance and a highly flammable/explosive material. EO vessels must contain this toxic gas (immediately dangerous at 800 ppm) while addressing explosion risks from decomposition or air mixing. The combination of toxicity and flammability makes EO among the most challenging lethal service applications, requiring specialized design approaches.
Application Importance
Ethylene oxide sterilization enables safe use of medical devices that cannot withstand heat or radiation sterilization—a critical healthcare capability. EO also serves as a chemical intermediate for producing ethylene glycol (antifreeze), surfactants, and numerous other products. The dual toxic/flammable nature demands vessels designed for both hazards, with explosion containment features complementing lethal service requirements. Roben Manufacturing provides vessels meeting this unique combination of requirements.

Frequently Asked Questions
What special requirements apply to ethylene oxide (eo) systems 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.
