Pressure Vessel and Pipefitter roles often overlap in industrial settings, but they focus on different aspects. Pressure Vessel specialists primarily design, fabricate, and inspect vessels that contain high-pressure fluids, requiring specific certifications. Pipefitters install and maintain piping systems, including those connected to pressure vessels. Both roles are essential in industries like oil and gas, chemical processing, and power generation, but they serve distinct functions within the industry.
