In API600, 2015, has the combination of internals 1 and 2 been discontinued?
Thread Content
I would like to ask the experts: in API600, version 2015, Table 8 – the items related to internal components – have been discontinued. What’s the reason for that?
In version 2015 of API600, if you are referring to internals 1 and 2 being marked as obsolete in Table 8, this generally means that the design or materials of these components are no longer recommended for use, possibly due to the availability of better alternative materials or design improvements. The specific reasons for disposal may include technological upgrades, improved safety standards, or stricter environmental requirements. It is recommended to consult the latest version of the API600 standard or relevant industry updates for more detailed information. .
In the 2015 version, the table indeed shows that 1 # 2# TRIM has been removed.
Version 2021 of No. 2 is still available; No. 1 has been discontinued
