In API 936, ITP stands for Inspection and Test Plan. It’s a crucial document that outlines the quality control procedures for refractory installation. This plan ensures that the refractory lining is installed correctly and meets the required specifications for long-term performance and safety.

Here’s a breakdown of what an ITP in API 936 typically includes:

1. Scope: Clearly defines the area or equipment where the refractory work is being performed.

2. Responsibilities: Identifies the roles and responsibilities of all parties involved, including the contractor, inspector, and owner.

3. Inspection and Testing Requirements:

• Materials: Verification of materials against specifications, including certificates of conformance, physical properties (density, CCS, etc.), and storage conditions.

• Surface Preparation: Inspection of substrate for cleanliness, dryness, and proper profile. Surface preparation for refractory installation
• Installation: Monitoring of mixing procedures, application techniques, curing conditions, and drying procedures.
• Testing: Conducting tests like hot strength, abrasion resistance, and permeability as required.
• Documentation: Recording all inspection and test results, deviations, and corrective actions taken.

4. Acceptance Criteria: Defines the standards that must be met for the refractory installation to be accepted.

5. Hold Points: Specifies critical stages in the installation process where work must be stopped for inspection and approval before proceeding.

Benefits of using an ITP:

• Reduces Risk: Helps prevent costly rework and failures by ensuring quality throughout the installation process.
• Improves Communication: Provides a clear understanding of expectations and responsibilities among all parties.
• Enhances Safety: Ensures compliance with safety regulations and minimizes potential hazards.
• Increases Efficiency: Streamlines the inspection process and facilitates timely completion of the project.

By adhering to a well-defined ITP, you can ensure the integrity and longevity of your refractory lining, ultimately contributing to the safe and efficient operation of your equipment or facility.
