Lethal Service Pressure Vessels
BEPeterson is a Lethal Service Pressure Vessel Manufacturer.
Requirements for lethal service pressure vessels can found in ASME VIII-1 section UW-2 (2007 edition). The ASME Code specifically places the responsibility of proper classification on the user of the vessel. According to the Code, a lethal substance is a “poisonous gas or liquid of such a nature that a very small amount of the gas or the vapor of the liquid mixed or unmixed with air is dangerous to life when inhaled”.
It is up to the user to determine if a service is lethal. BEPeterson cannot determine if a pressure vessel will be used in environment that falls under the lethal definition of the Code.
Two definitions of lethal service are provided in UW-2:
A vessel is to contain fluids of such a nature that a very small amount mixed or unmixed with air is dangerous to life when inhaled.
By “lethal substances” are meant poisonous gases or liquids of such a nature that a very small amount of the gas or of the vapor of the liquid mixed or unmixed with air is dangerous to-life when inhaled. For purposes of this Division, this class includes substances of this nature which are stored under pressure or may generate a pressure if stored in a closed vessel.
BEPeterson is an ISO 9001 certified manufacturing facility. We have installed strict processes for Quality and Inspection Plans in production of lethal service pressure vessels. BEPeterson’s Engineers and Quality staff are well versed in the design and manufacturing process for lethal service pressure vessels. We work closely with our customers to ensure the vessel meets the requirements for their application.
Lethal Service Tanks can be built to a variety of sizes and can be furnished for atmospheric pressure, or designed for internal and external pressure. All materials are available including stainless steel, nickel alloys and reactive metals. As with other pressure vessels, these can be provided in many material finishes and weld finishes.
Lethal Service Tanks will usually receive the “L” stamp on the ASME data plate indicating design and construction meet the guidelines set by the ASME Boiler and Pressure Vessel code. Special consideration of each vessel is required for fitting types, wall thickness, and non-destructive testing. Vessels can be designed in both vertical and horizontal configurations.
