API 936 Refractory Inspection Code - Application, Installation, Inspection, Testing & Repair

What is (API 936) about?

Refractory Personnel Certification Program will be based on testing candidates’ knowledge of API Recommended Practice 936, Refractory Installation Quality Control Guidelines. API Recommended Practice 936 provides guidelines for the installation quality control of monolithic refractory linings and may be used to supplement owner specifications.  The document includes material, equipment and personnel qualification requirements along with procedures and responsibilities for quality control inspection personnel.  Refractory quality is closely monitored based on the document’s defined procedures and acceptance criteria.

The purpose of the program is to provide third-party certification of refractory inspection personnel by examination.  The certification examination would cover, at a minimum, the following criteria defined by API Recommended Practice 936, “Refractory Installation Quality Control Guidelines – Inspection and Testing Monolithic Refractory Linings and Materials”:

What is API 936 about?

  • The American Petroleum Institute has developed the API 936 Refractory Personnel Certification Program to help the industry identify qualified refractory personnel. The Refractory Personnel Certification Program (RPCP) is an integral part and a logical addition to other Individual Certification Programs managed by API.

API 936 refers to a standard developed by the American Petroleum Institute (API) that provides guidelines for the installation, inspection, testing, and maintenance of refractory linings in petrochemical and other industries. Refractory linings are materials resistant to high temperatures, used to protect equipment like furnaces, kilns, and reactors from thermal, mechanical, and chemical stresses.

The API936 standard includes detailed procedures for:

1. Material Selection and Specification
2. Installation Practices
3. Inspection and Testing
4. Maintenance and Repair
