Abstract

This project was discussed about the critical Quality Assurance (QA) and Quality Control (QC) in process and procedure to ensure that the manufacture of pressure vessel that been produces were in high quality. Quality control (QC) is very important in order to produces the pressure vessel, without the details test will lead the failure to the pressure vessel. This project was collaboration with Akra Engineering Sdn.Bhd which is part of oil and Gas Company in Malaysia. This project also used the AMERICAN SOCIETY MECHANICAL ENGINEERING (ASME) code as reference which is ASME BOILER and PRESSURE VESSEL CODE VIII. Quality assurance (QA) and quality control (QC) process were divided into 6 parts. The first part is documentation review, material control, fabrication process, inspection and testing. The inspections were start with the documentary check followed by repairing the defect instantly. Each procedure should be test to prevent the defect from occur. The procedure that should be held was Inspection Test Plan (ITP) and Welding Procedure Specification (WPS). The material receiving inspection was to ensure that the materials that deliver were same as the purchase order and material certificate. All the material should obeyed the specification code that already fixed. Fabrication part was the critical part that should be highlight because this part was the beginning of pressure vessel construction. As were mention above, all parts should been details check in order to prevent the defect and failure especially to the welding. The inspection and test part explains that when the pressure vessel is already done, it then was tested by Non-Destructive Examination (NDE) and Hydrostatic Test.
