Which organization approves standards for pressure vessels in the United States?

The American Society of Mechanical Engineers (ASME) is the organization responsible for approving standards for pressure vessels in the United States. ASME's Boiler and Pressure Vessel Code (BPVC) provides rigorous guidelines for the design, manufacture, and maintenance of pressure vessels, ensuring safety and reliability. The standards set forth by ASME are widely used in various industries that involve the handling of pressurized systems, including oil and gas, chemical processing, and power generation.

While other organizations mentioned may play significant roles in related fields—such as the USDA which focuses on agriculture, the OSHA which sets workplace safety regulations, and AIGA which pertains to industrial gases—they do not specifically set standards for pressure vessels. ASME’s robust framework is essential in maintaining safety standards for vessels that contain gases and liquids under pressure, and adherence to these standards is crucial for preventing accidents and ensuring operational integrity.
