Pressure Vessels

Teledyne Brown Engineering has the capability to manufacture Pressure Vessels under ASME U and UM Certificates of Authorization, as well as safety-related units. 

We are the only manufacturing company in Alabama to hold the five Certificates of Authorization issued by the American Society of Mechanical Engineers (ASME):  the N, NPT, U, UM, and NS.  These stamps sanction TBE to design and manufacture nuclear vessels, piping systems, tanks, storage systems, core support structures, assemblies, and pressure vessels.  To receive and maintain these Stamp certifications, we must meet and maintain rigorous manufacturing standards and successfully complete an extensive on-site audit and demonstration by ASME Boiler and Pressure Vessel Code representatives every 3 years.     

We also have the capability to design and manufacture prototypes and one-of-a-kind productions.  An example of such work was when Teledyne Brown engineered and manufactured accessory skids for a prototype Gas Turbine Backup Generator System for use in nuclear power plants. The components included two 2,000-gallon air receivers (500-psig working pressure), 1,250-gallon fuel oil day tank and skid, and two air start skid assemblies to provide startup air to the turbine. The system was designed, manufactured, tested, and stamped per ASME Section III. 

As part of the effort, TBE used its ASME Material Organization Authorization to procure unqualified ASME source material and “upgrade” it to ASME code material.  This process, which in many ways is similar to a commercial grade dedication process, involved conducting chemical and physical tests on each piece of material to be upgraded.  TBE-certified inspection personnel then evaluated the chemical and physical data against the original Certified Material Test Report data and the ASME Material Specification for consistency and compliance before accepting and upgrading the material for use in the hardware.
