Accessing the official is vital for corrosion engineers, inspectors, and maintenance managers for several reasons:

To improve the reliability of equipment inspections by providing guidance on the application of specific NDT techniques for identified damage mechanisms.

Used as a rapid screening tool to identify potential sites of HTHA or weld defects. Phased Array Ultrasonic Testing (PAUT): api rp 586 pdf

Standardized tables for reporting HTHA data for hotspots and welds. 2. Contact Point Corrosion (Section 3 - Draft)

For practical implementation, start with a baseline condition assessment to document coating condition and CP performance. Establish a routine schedule for coating repairs and CP testing—many operators find semiannual to annual CP checks effective, with more frequent checks where interference or aggressive environments exist. Pay special attention to areas prone to moisture accumulation, HVAC condensate, gutter run-off, and mechanical damage. Accessing the official is vital for corrosion engineers,

ISO 3171 (Automatic Pipeline Sampling) is an international standard. API RP 586 is more focused on refinery and terminal situations where sample system retrofits, safety hazards, and operator training require practical, local guidance. Both are complementary; many engineers use ISO 3171 for fundamental math (e.g., determining sample cycle intervals) and RP 586 for the mechanical design and safety implementation.

The document is structured into parts based on equipment types or damage mechanisms: Pay special attention to areas prone to moisture

Highly effective for monitoring the depth and propagation of HTHA fissures.
