Third Party Inspection for Pressure Vessel –

-
Definition- A  pressure vessel  is a container designed to hold gases or liquids at a  pressure  substantially different from the ambient  pressure . Design involves parameters such as maximum safe operating pressure  and temperature, safety factor,corrosion allowance and minimum design temperature (for brittle fracture). Reference Documents and Codes- Design code Purchase order specification Purchaser's standards Approved drawings ASME SEC VIII Div 1 or 2 ASME V ASME IX Note- ASME SEC VIII Div 1 for (15-3000) psi ASME SEC VIII Div 2  for (3000-10000) psi ASME SEC VIII Div 3  for more than 10000 psi 1. Division 1  is based on normal stress theory, 2. Division 2  is based on maximum distortion energy (Von Mises). Inspection Activities from start to finish- Material Inspection Fabrication Preparation for Welding Fit-Up Inspection Monitoring of Weld Conditions Back Gouging Inspection Visu...
