Api-936
The API 936 Refractory Personnel certification is designed to identify candidates possessing the knowledge of API STD 936 Refractory Installation Quality Control Guidelines. These are guidelines for the installation quality control of monolithic refractory linings and may be used to supplement owner specifications
API 936 is a specification published by the American Petroleum Institute (API) that provides guidelines and standards for the installation, inspection, and testing of refractory linings in industrial equipment used in high-temperature environments, such as furnaces, reactors, and kilns.
Refractory linings are materials that are designed to withstand extreme heat, corrosion, and wear, often used in industries like refining, petrochemicals, and power generation. The API 936 standard ensures that these materials are properly selected, installed, and maintained for safe and efficient operation.
Key Components of API 936:
- Material Selection: Specifies the types of refractory materials that can be used based on the operating conditions, such as temperature and chemical environment.
- Installation Practices: Describes the proper methods for installing refractory linings, including preparation of surfaces, application techniques, and curing processes to ensure durability and performance.
- Inspection and Testing:
- Non-destructive testing (NDT) methods for checking the integrity of the lining.
- Destructive testing (when necessary) to verify the quality of the installed material.
- Visual inspection criteria to detect cracks, gaps, or imperfections.
- Quality Control: Outlines the procedures for quality control during installation, including tolerances, acceptance criteria, and documentation requirements.
- Personnel Qualifications: The specification also includes recommendations for the qualifications and certifications of personnel involved in the installation, inspection, and maintenance of refractory linings.
Applications of API 936:
- Refineries: Protecting the internal surfaces of process equipment subjected to high temperatures, such as catalytic crackers and heaters.
- Petrochemical plants: Lining reactors and furnaces to handle corrosive gases and chemicals.
- Power generation: Boilers and turbines exposed to high thermal stress.
API 936 helps ensure that refractory systems are installed and maintained to meet safety, performance, and longevity standards in critical industrial processes.
