Japanese pressure vessel code (KHK certification)
Japanese pressure vessel code (KHK certification)
(OP)
I am looking for general hydrotest information for Japan's KHK certification for pressure vessels. Specifically, how is the hydrotest pressure defined? Is it a similar test comparable to UG-99 and if so what parameters are used; i.e. 1.3 X MAWP or some other factor? What is the ramp up and hold times? Any experience anyone could share in this area would be greatly appreciated.

If you are with HSB go to their website.
Check:

for a start. 1.5 MAWP is typical but there are variations. If you do not get design review you may be out of luck.
