|With nearly 30 years of experience in fabricating, we are experts in the design, engineering, manufacturing, testing, and certification of Pressure Vessels. We are certified to manufacture unfired pressure vessels whose construction complies with ASME Code, Section VIII, Division I and welding in accordance with Section IX. Highland labels ASME vessels with a "U" for unfired pressure vessels with authority granted by the National Board of Boiler and Pressure Vessel Inspectors. We are also certified to make alterations or perform repairs on vessels in operation, in which case an "R" label would be applied. Additional codes such as NFPA and AWWA may affect design requirements if the vessel is to be used for water service. Our ASME Code approved quality control program monitors the design, materials, construction, welding, and testing methods employed throughout the vessel production.
