Metric/British Equivalency for PV Bolting

[michigander]

I have a test unit to build stateside that is to be shipped to England, and potentially Korea. The bonnets are bolted and the materials I use should be easily replicated and replaceable overseas. What overseas bolting materials are comparable to the SA-193-B7 and SA-194-2H used stateside?

Thanks in advance,

Michigander

The British equivalent used to be BS4882-B7 and BS4882-2H.
It might have changed now - I haven't used it for about 20 years.

Refer to Norsok Standard M-001 (free download), chapter 5, bolting materials and applicable standards;- they are using the same ASTM A 193 / 194 standards.

You can get those materials anywhere, just like you can get ASME flanges anywhere. We use them here in Australia, fabricators from Indonesia, Singapore, UK, etc, that we have dealt with also use them.

SA/A193 B7 and SA/A194 2H are very common where your unit is going, so just stick with it. In fact, most of the B7 bolts that I use in Malaysia come from Korea and EU.
