P3 Engineering develops software for the mechanical design, analysis and assessment of pressure vessels according to national and international standards. Our products are used to manufacture, maintain and inspect pressure equipment or parts thereof. Together with our customers we strive for accessible and reliable software to carry out this work as well as possible. Our mission is to make the knowledge in norms and standards for pressure vessels available in a clear, comprehensible and verifiable manner. This should lead to a better design that is safe, sustainable and economic. Not only the standards are important here, but also practical knowledge of manufacturing and maintenance of pressure equipment like calculating bolt tightening torques for sealing flanges or analyzing corroded pressure vessel components. We do this by developing innovative and accessible software which meets the standards and also takes into account manufacturability and maintainability
