QA/QC is the combination of Quality assurance, the process or set of processes used to measure and assure the quality of a product, and quality control, the process of ensuring products and Services meet consumer expectations.
Quality assurance is process oriented and focuses on defect prevention, while quality control is product oriented and focuses on defect identification.
QC in Welding Inspection:
- Duties of a Welding Inspector
- Welding Imperfections and materials Inspection
- Welding Documentations (PQR, WPS, WPQ)
- Codes and standards
- Welding Symbols
- Introduction to Welding processes
- Visual Inspection
- Welding Safety
- Welding terms and definitions
- Welding acceptance criteria
Piping systems are like arteries and veins. They carry the lifeblood of modern civilization. In a modern city they transport water from the sources of water supply to the points of distribution; convey waste from residential and commercial buildings and other civic facilities to the treatment facility or the point of discharge. Similarly, pipelines carry crude oil from oil wells to tank farms for storage or to refineries for processing. The natural gas transportation and distribution lines convey natural gas from the source and storage tank forms to points of utilization, such as power plants, industrial facilities, and commercial and residential communities.
In chemical plants, paper mills, food processing plants, and other similar industrial establishments, the piping systems are utilized to carry liquids, chemicals, mixtures, gases, vapors, and solids from one location to another. The fire protection piping networks in residential, commercial, industrial, and other buildings carry fire suppression fluids, such as water, gases, and chemicals to provide protection of life and property. The piping systems in thermal power plants convey high pressure and high-temperature steam to generate electricity. Other piping systems in a power plant transport high- and low-pressure water, chemicals, low-pressure steam, and condensate. Sophisticated piping systems are used to process and carry hazardous and toxic substances. The storm and wastewater piping systems transport large quantities of water away from towns, cities, and industrial and similar establishments to safeguard life, property, and essential facilities.
