Selection criteria for RX and BX type octagonal sealing ring gaskets
Thread Content
Are there any standards for selecting the BX and RX type metal gaskets used in oil trees? That is, which type of gasket corresponds to a certain weight rating, or is it sufficient to consider only the dimensions? Why isn’t there any relevant information in the standards? I’ve checked ASME B16.5, ASME B16.2, API S6A, and GB/T22513, but couldn’t find anything on this topic :(
Check this standard; it’s available in the 1992 version. API SPEC 17D-1992 Subsea Wellhead and Christmas Tree Equipment (with Supplements 1&2)
Thank you, senior. I’ll go take a look right away. I have one more question: the current standards do not clearly specify how to select or calculate R, RX, and BX type sealing gaskets. Have these gaskets been phased out, or are there other rules for selecting them? :handshake
I’m not very familiar with this. Oil trees seem to be more commonly used in shipyards and offshore engineering. However, on the imarine forum, the responses don’t seem as quick as those from HaiChuan; there are many generic replies.
ASME B16.20 ring sizes have corresponding specified pressures, and API 6A also has corresponding ones
