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

In industrial valve selection, understanding key standards is crucial for safety and performance. This article explores two commonly referenced specifications: ASME B16.34 and API 600. While both govern valve manufacturing, their scope and applications differ significantly.

Core Functions and Scope

ASME B16.34 outlines requirements for valve design, materials, and pressure-temperature ratings. It covers valves made from various materials, including cast, forged, and fabricated constructions. API 600 specifically addresses bolted bonnet steel gate valves for petroleum and natural gas industries, emphasizing durability and fire safety.

Material Specifications and Testing

ASME B16.34 provides guidelines for material groups and pressure-temperature ratings, while API 600 mandates rigorous material traceability and additional non-destructive examination (NDE) requirements. API 600 valves often include supplementary fire testing per API 6FA.

Common Questions Answered

Which standard applies to gate valves in refineries?

API 600 is typically specified for critical refinery applications due to its stringent material and testing requirements.

Can a valve comply with both standards?

Yes, manufacturers can design valves meeting both specifications, though additional testing and documentation may be required.

Industry Applications and Selection Guide

Choose ASME B16.34 for general industrial applications with varied valve types. Opt for API 600 when handling hydrocarbons, high-pressure systems, or where fire-safe certification is mandatory. For detailed comparisons of two commonly asme b16 34 and api 600, visit our technical resource page.
