Most pressure vessels are cylindrical in form and are designed using cylindrical shell theory. There are various practical requirements such as the need for cylinder end closures, holes for inlet/outlet pipes and attachments. Further design criteria must then be applied to take account of the probability of weld flaws and similar defects. With many years of designing pressurised systems, we specialize in designing Pressure Vessels to comply with ASME VIII Div 1, PD5500, EN13445 and PED requirements. Once the design is complete, we provide you with a full pack of manual calculations, fabrication drawings, safety instructions and FEA reports.
