LETHAL SERVICE
PRESSURE VESSELS
For jobsites that handle potentially hazardous gases and liquids, precise and durable equipment is crucial. The ASME Code requires proper vessel classification for lethal services. The code defines a lethal substance as a poisonous gas or liquid that, when mixed or unmixed with air, can cause danger to life. A lethal service includes substances that may generate pressure once stored in a closed container.
As a holder of the ASME single certification mark, BEPeterson adheres to the stringent requirements of the ASME Boiler and Pressure Vessel Code. We have the experience and expertise to customize pressure vessels to meet your application requirements and industry standards.

Custom ASME Lethal Service Pressure Vessels
Choose BEPeterson for high-quality heavy-gauge metal solutions tailored to your industry needs. We are your trusted lethal service pressure vessel manufacturer, designing and fabricating solutions based on your demands and the stringent ASME provisions.
Lethal Service Pressure Vessel Design
Our design process complies with the strict code protocol set by ASME for a lethal service pressure vessel. Our dedicated team will work closely with you to ensure the right design and size for your needs. Our flexibility allows us to design metal solutions for different pressure types, either internal or external. We can also furnish lethal service tanks for atmospheric pressures. Vessels can be designed in both vertical and horizontal configurations, too.
You can choose from our wide range of metal options, including:
- Stainless steel
- Nickel alloys
- Reactive metals
Engineering for Lethal Service Vessels
Along with our ASME accreditation, we are an ISO 9001-certified manufacturing facility that follows a strict process for quality and inspection plans. Our engineers and quality staff are well-versed in producing lethal service pressure vessels. We assign a specific engineer for every project and use the latest design and engineering software for quality and precision. Count on us to meet special considerations of each vessel, such as:
- Fitting types
- Wall thickness
- Non-destructive testing
Meeting ASME Lethal Service Requirements
Before the material procurement and manufacturing process, we conduct comprehensive quality and safety inspections to adhere to the ASME code and other industry certifications for lethal services. Every lethal service pressure we produce receives the “L” stamp on the ASME data plate as an indication of ASME Boiler and Pressure Vessel Code compliance.
BEPeterson's ASME Lethal Service Offerings
- Complete In-House Process: The entire pressure vessel design and manufacturing processes are performed in-house at our ISO 9001-certified manufacturing facility.
- Flexible Configuration Options: The vessels can be designed in either horizontal or vertical configurations. Our lethal service tanks are constructed with the intention of using them in applications with specific pressures (atmospheric, internal, or external).
- Material Versatility: We are capable of working with different types of metals according to the client’s requirements. These can include nickel alloys, reactive metals, and different types of steel. We can also provide the vessels with weld and material finishes of the client’s choice.
- Quality Assurance Process: Once completed, the lethal pressure vessels undergo strict quality and inspection processes to ensure that they can meet all application requirements. They are also inspected by a certified inspector.
Why Choose BEPeterson's Lethal Service Pressure Vessels
1. Fabricated as per ASME Guidelines
Our lethal service pressure vessels are fabricated as per the ASME guidelines. We adhere to ASME Section 8 guidelines. We strictly follow ASME Section 9 welding guidelines. Our pressure vessels are “L” stamped to indicate that they meet the ASME Boiler and Pressure Vessel Code.
2. Durable Designs
Lethal service pressure vessels are made from high-quality materials, which helps in resisting corrosion. Various materials such as stainless steel, nickel alloy, and reactive metals are used in the fabrication process.
