Quality control and assurance are essential to the integrity, safety, and efficiency of engineering projects, particularly in sectors where piping systems play a central role. The OSHAA 30-Hours Professional Diploma in Quality Assurance / Quality Control (QA/QC) and Piping Engineering is a specialised training programme designed to equip participants with industry-relevant knowledge and practical competencies. Offered by OSHAA, a recognised awarding body, this course meets international standards and prepares participants for technical and supervisory roles across multiple industrial sectors.
This diploma is structured to support the development of core skills in piping inspection, materials selection, quality documentation, and compliance with globally accepted codes such as ASME, API, and ISO. It is ideal for those looking to expand their capabilities in quality assurance or those entering the field of piping engineering with a focus on quality systems and inspection procedures.
Over the 30-hour curriculum, participants engage in focused study units covering piping materials and fabrication methods, welding processes, inspection planning, and non-destructive testing techniques. The course places strong emphasis on interpreting engineering drawings, understanding international standards, and applying quality control protocols across the full lifecycle of piping projects.
Through this programme, participants gain the ability to identify fabrication and welding defects, interpret piping isometrics, and contribute to quality audits and inspections on industrial sites. Practical insight into documentation such as WPS (Welding Procedure Specifications), PQR (Procedure Qualification Records), and NDT (Non-Destructive Testing) reports is also a core element of the training.
Whether entering the profession or seeking to formalise existing experience, participants will finish the course with the confidence and technical proficiency required to operate in demanding QA/QC and engineering environments. The diploma is especially relevant to industries such as oil and gas, petrochemicals, power generation, and large-scale construction, where safety, accuracy, and regulatory compliance are non-negotiable.
