Frequently Asked Questions:

API 600 covers bolted bonnet steel gate valves for the petroleum and natural gas industries, specifically where “corrosion, erosion, and other service conditions indicate a need for full port openings, heavy wall sections, and extra-large stem diameters.

What is the difference between API 6D and API 600?

What is the difference between API 600, 602 and API 6D valves. API 600, 602 are heavy duty valves for petroleum refinery and related services. API 6D mainly applies to Pipeline valves.

What is API 6D testing?

It is the standard that provides specifications for ball valves, check valves, gate valves, and even plug valves used mainly in pipelines.

Is API 600 A full port?

The Api 600 gives the range of flow pass, this is between reduced to full port.

What is the latest edition of API 598?

Revision: 10th Edition, October 2016. Published Date: October 2016.

What is API 6D?

This specification defines the requirements for the design, manufacturing, assembly, testing, and documentation of ball, check, gate, and plug valves for application in pipeline and piping systems for the petroleum and natural gas industries.

What is the difference between API 598 and API 6D?

Difference In Test Medium

For low-pressure closure tests, the test medium for API 598 is air or inter gas, whereas the test medium for API 6D is air or nitrogen. For high-pressure closure tests, the test medium for API 598 is air, kerosene, inert gas, water, or non-corrosive liquid.

What does API 608 mean?

API 608 is a standard which exceeds the requirements set by ASME B16. 34, thereby offering a superior level of performance for the rigorous requirements of the petrochemical, power, oil and gas and water treatment markets.

What is the difference between API 600 and API 602?

This specification covers the same details small forged gate valves that API 600 does for larger valves. API 602 further gives dimensions for extended body valves which are used extensively in industrial facilities. Another important gate valve specification is ASME B16. 34
