In the Non-Destructive Testing (NDT) industry, API Std 622 plays a crucial role in ensuring the safety and environmental compliance of equipment used in various sectors such as oil and gas, petrochemicals, power generation, and more. This article provides an elaborate overview of API Std 622 and highlights the expertise of NDT and PWHT Solutions, a leading company known for delivering exceptional emissions testing and NDT services.

Understanding API Std 622:

API Std 622, formally known as “Type Testing of Process Valve Packing for Fugitive Emissions,” is a specification developed by the American Petroleum Institute (API). It establishes testing protocols and requirements for valve packing used in process equipment to minimize fugitive emissions. Fugitive emissions refer to the unintentional release of gases or vapors into the atmosphere from equipment such as valves, pumps, and other sealing systems.

The standard aims to ensure that process valve packing effectively seals and reduces fugitive emissions, thereby promoting safety, protecting the environment, and complying with regulatory standards. API Std 622 specifies the testing methodology, acceptance criteria, and performance requirements for various types of valve packing materials and designs.

Key Aspects of API Std 622:

Testing Methodology: API Std 622 outlines specific test procedures to evaluate the emission performance of valve packing under different operating conditions and stressors. These tests include leakage measurements, temperature cycling, thermal aging, and more.

Acceptance Criteria: The standard defines acceptable emission limits based on the type of valve packing and the intended service conditions. It sets benchmarks for acceptable leakage rates, ensuring that equipment meets industry-specific emission standards.

Performance Requirements: API Std 622 identifies the necessary performance characteristics of valve packing materials, such as durability, resilience, chemical compatibility, and thermal stability. It helps manufacturers and end-users select suitable packing materials for their specific applications.
