Quality control plays a critical role in ensuring the safety, reliability, and efficiency of piping systems in industrial projects. The OSHAA 30-Hours Professional Diploma in QA/QC Piping Inspector is a professionally recognised qualification designed to equip participants with the core competencies required to carry out quality inspection, assessment, and compliance tasks in line with international standards.
This industry-aligned diploma is awarded by OSHAA, a reputable body committed to delivering high-standard professional development courses. The qualification is structured to provide practical knowledge of QA/QC principles, inspection techniques, and documentation processes that are essential for ensuring the integrity of piping installations in sectors such as oil and gas, petrochemicals, construction, and power generation.
Through this comprehensive 30-hour programme, participants will gain a strong foundation in piping materials, fabrication practices, welding processes, and non-destructive testing methods. The course places particular emphasis on interpreting engineering drawings, identifying piping defects, and following international codes such as ASME, API, and ISO. Each unit is carefully designed to support hands-on application of QA/QC techniques in real-world industrial settings.
Participants will also learn to interpret piping isometrics, execute inspection and test plans (ITPs), and contribute to the preparation and review of essential quality documentation including welding procedure specifications (WPS), procedure qualification records (PQR), and non-destructive testing reports. By the end of the course, participants will be well-prepared to undertake responsibilities associated with piping quality inspections during fabrication, erection, and commissioning phases.
This diploma serves as an ideal stepping stone for participants aiming to secure positions such as QC Inspector, QA/QC Technician, or Quality Supervisor, while also benefiting those in engineering and site supervision roles who require a deeper understanding of inspection protocols and quality documentation. Through its focused curriculum, this course empowers participants to make a meaningful impact in quality-driven project environments.
