Expansion Loop Rated for 225 psi?

[sl3656]

Can someone suggest available manufacturers that supply seismic movement joints that have a maximum working pressure of 225 psi for 6-inch pipework?

I am looking at Metraflex and their Fireloops are rated at 175 psi working pressure for the 6-inch version. Any suggestions greatly appreciated!

Do it the old-fashioned way. 6 elbows, 10 couplings (see Fig. A.9.3.3(a) in the 2013 edition). Should be no issue getting fittings rated for at least 225 psi.
