BS6364 Leakage rate

BS6364 Leakage rate

BS6364 Leakage rate

(OP)
Can someone tell me what the allowable leakage rate is for Spec BS6364 Cryo testing

RE: BS6364 Leakage rate

I may be mistaken...or simply out of date with my info, but, I believe these are the same as per SPE 77/306 (I know they used to be the same).
Any one have more recent info ?
Ciao,

RE: BS6364 Leakage rate

   According to BS 6364 standard, para. A.3.1.4(d), the maximum allowable seat leakage is

          100 mm3/s per mm of ND  =  150 ml/min per in of DN,

for all valve types except check ones (that are allowed two times the above mentioned leakage).



   Shell MESC SPE 77/306 specification in now withdrawn, as it has been superseded by Shell MESC SPE 77/200 in June 2007.


Hope this helps,     'NGL
