The pressure test for API 598 is slightly less pressure and less duration than API 6D.
API 6D is specifically for pipeline valves.
API 6D does not automatically meet or exceed API 598 because both standards serve different purposes. API 6D is mainly for pipeline valve design and overall requirements, while API 598 specifically focuses on valve inspection and pressure testing, making it more detailed for testing procedures.
Both deal with valves. API6FA is for API 6A and 6D. API607 applies to soft-seated, quarter-turn valves.
It's quite easy. API 6A speaks about wellhead and x-mas tree equipment, API 6D speaks about pipeline valves. If you are phisically looking to one valve, you can also understand if it belows to 6A or 6D giving a look to the valve label. On the label you can read the class of the valve. If the class is 2000 or 3000 or 5000 or 10000 or 15000 or 20000 the valve is 6A. If the class is 125 or 150 or 300 or 400 or 600 or 900 or 1500 or 2500 the valve probably is a 6D ("probably" because the same classes of API 6D are used also by other API standards, like 594, 600, 608, ecc ecc).
API 6D and API 594 are both standards from the American Petroleum Institute, but they are used for different purposes in piping and valve systems. API 6D is mainly used for pipeline valves in oil and gas transportation. It applies to valves like gate, ball, plug, and also some check valves that are used in large pipeline systems where safety and reliable shut-off are very important. API 594, on the other hand, is only for check valves. These valves are used to stop backflow of fluid in piping systems, usually inside plants, refineries, and industrial setups.
API 6D is a specification developed by the American Petroleum Institute that outlines the requirements for pipeline and piping valves used in the oil and gas industry. It encompasses design, manufacturing, testing, and performance standards for various types of valves, including gate, ball, check, and plug valves. Compliance with API 6D ensures that these valves can operate safely and reliably under specified conditions, contributing to the overall integrity of pipeline systems.
BS Standard is a Specification for steel globe and globe stop and check valves (flanged and butt-welding ends) for the petroleum, petrochemical and allied industries the list below are standards that i wish help to you API 600 API 6D API 6A ASME B16.5 ASME B16.34

API 6D is a pipeline valve standard that is commonly used for valves in oil and gas pipelines. In most pipeline applications, these valves are made full bore so that cleaning and inspection tools can pass through without obstruction. However, the standard itself does not strictly require every valve to be full bore, as it depends on the design and service requirements.
If -6d = 42 then 6d = -42. then divide by 6, d = -7
The Savage 6D Deluxe is a .22 caliber semi automatic rifle. It has a 24 inch barrel length and was manufactured between 1945 and 1968.
-6d = -42-6(7) = -42d = 7
72-6d=6 subtract 72 from both sides -6d=66 divide by -6 d=-11
