Api Rp 586

While ( Inspection of Pressure Relieving Devices ) focuses on the physical inspection techniques and "how-to" of inspecting the valves, API RP 586 focuses on the strategy and risk analysis behind determining when those inspections should happen.

API RP 586 focuses on two main optical methods:

Refinery tank farm (50 tanks, 200 valves, 50 flanges). Goal: Identify and quantify methane leaks >10 g/hr for internal reduction target. Using API RP 586 QOGI approach: api rp 586

The primary goal of API RP 586 is to move away from prescriptive, time-based inspection intervals (e.g., "inspect every 5 years") toward a more strategic, risk-based approach. It provides a methodology for:

The recommended practice covers several critical areas:

It is a standard developed by the American Petroleum Institute (API) to provide guidance on establishing and managing a Risk-Based Inspection (RBI) program specifically for pressure relief devices (PRDs), such as pressure relief valves and rupture disks. Using API RP 586 QOGI approach: The primary
