SECTION VII RULES FOR CONSTRUCTION of PRESSURE VESSELS Division 1 Division 2 Alternative Rules Up to 70MPa Division 3 Alternative Rules for construction of high pressure vessels Above 70Mpa Up to 20MPa Widespread use No stress analysis SECTION VII RULES FOR CONSTRUCTION of PRESSURE VESSELS

SECTION IX WELDING & BRAZING QUALIFICATIONS 1. Relates the qualifications of welders and welding operations, brazers and brazing operations and procedures. 2. Establishes basic criteria for welding — weld orientations, tests and examinations, braze orientations and various tests. 3. A welding operation may be qualified mechanical, bending tests, and radiography, unlike brazing.

ASSIGNMENTS Made basic design calculations as per ASME SECTION VIII Division 1 and made fabrication drawings on CAD of the following equipment: UH-25 scrubber (Satish Dhawan Space Centre, Sriharikota) b) ECR proton source LCW holding tank (Bhabha Atomic Research Centre, Mumbai) c) Isrosene storage tank (ISRO Liquid Propulsions Systems Centre, Mahendragiri)

CONCLUSION Engineering problem solving skills The ASME BPVC is a very comprehensive code PV Elite, which has pre-feeded standardized values : Reference, page 37 Testing, Inspection and Certification (TIC) purpose A project requires thorough co-operation from all departments No single NDT technique serves all the purpose.
