Comparing ASME B16.34 and API 600: Key Differences and Applications

When selecting valves for industrial applications, engineers often encounter two commonly ASME B16.34 and API 600 standards. These specifications ensure safety, reliability, and performance in high-pressure and high-temperature environments. Understanding their distinctions helps in making informed decisions for projects in oil, gas, and power generation sectors.

Scope and Application Focus

ASME B16.34 covers valve design, materials, and pressure-temperature ratings for a broad range of industries, including power plants. In contrast, API 600 specifically targets bolted bonnet steel valves for petroleum and natural gas services. This difference in scope means API 600 includes additional requirements for fire safety and leakage prevention, crucial for hydrocarbon processing.

Material and Testing Requirements

Both standards mandate rigorous material testing, but API 600 imposes stricter criteria for non-destructive examinations and shell strength tests. For instance, API 600 requires full radiographic inspection for critical welds, whereas ASME B16.34 allows alternative methods based on design classification.

Common Questions Answered

Can a valve comply with both ASME B16.34 and API 600?

Yes, manufacturers often produce valves meeting both standards, incorporating features like enhanced sealing and fire-safe designs to satisfy dual requirements.

Which standard is better for offshore platforms?

API 600 is typically preferred due to its focus on hydrocarbon services and resilience in harsh environments, though ASME B16.34 valves may be used in auxiliary systems.
