Lethal Service Pressure Vessels for Chemical Processing | Roben Manufacturing
Lethal Service Vessels for the Chemical Processing Industry
The chemical processing industry handles numerous substances classified as lethal under ASME Code, from common industrial chemicals like chlorine and ammonia to exotic intermediates in pharmaceutical and specialty chemical synthesis. These facilities require pressure vessels that maintain absolute integrity while containing substances where even minor releases can cause serious injury or death. Chemical processors face stringent regulatory oversight under OSHA PSM and EPA RMP, making code-compliant lethal service vessels essential for safe, legal operation.
Industry-Specific Requirements
Chemical processing lethal service vessels must resist corrosion from aggressive process streams while maintaining the structural integrity demanded by toxic contents. Designs accommodate process requirements including mixing, heating, cooling, and multiple nozzle connections while meeting mandatory 100% radiography and PWHT requirements. Material selection considers both corrosion resistance and code compliance—some materials cannot meet lethal service impact test requirements. Documentation must support PSM mechanical integrity programs throughout decades of service.

Frequently Asked Questions
What defines lethal service under ASME Code?
ASME Code defines lethal service as vessels containing poisonous gases or liquids of such a nature that a very small amount mixed or unmixed with air is dangerous to life when inhaled. This designation triggers mandatory additional requirements including 100% radiographic examination of welds, post-weld heat treatment, and enhanced documentation.
What materials does Roben recommend for chemical processing lethal service?
Material selection depends on the specific substances handled, process conditions, and corrosion environment. Our engineering team provides material recommendations based on your specific application, considering both technical performance and code compliance requirements. We work with stainless steels, nickel alloys, titanium, zirconium, and specialty alloys as appropriate.
How does Roben support our PSM/RMP compliance?
Roben’s comprehensive quality documentation directly supports Process Safety Management and Risk Management Program mechanical integrity requirements. We provide baseline data for inspection programs, maintain fabrication records, and can format documentation packages for your PSM files. Our engineering team is available to support mechanical integrity reviews and audits.
