NOTES:

1. BOLT MATERIAL SELECTION IS BASED ON ASSUMPTION THAT FLANGES WILL BE INSULATED AND HENCE PROCESS MEDIUM AND BOLT TEMPERATURES AREAPPROXIMATELY EQUAL. IN CASES IN WHICH FLOW TEMPERATURES EXCEED 850°F, FLANGES ARE NOT INSULATED AND METAL BOLT TEMPERATURE ISASSUMED TO BE 80% OF FLOWING MEDIUM TEMPERATURE.

2. OPERATING TEMPERATURES TO 500°F ARE PERMISSIBLE FOR L7 AND B8 BOLTS.

Notes:1. NPS 1 minimum size 6000# FS threaded couplings are permitted for pressure vessel connections within limits

of GEMS F-1M as to service, pressure, and temperature. In such cases, minimum pipe thickness to first blockvalve shall be Sch 160.

2. If heavy vibration of piping is anticipated, consideration shall be given to increasing listed minimumsizes.

3. This thickness may be reduced to 0.358 inch if using pipe for angular type nozzles in accordance withDrawings 7S-2919 and 7S-2921.

4. Exceptions to minimum size and thickness specified shall comply with to Section 5.4.5. If solid non-ferrous alloys and ferrous alloys with chromium content greater than 9% are required that

cannot be obtained in thickness specified, minimum size shall be NPS 1 1/2, Schedule 80 at vessels and NPS1, Schedule 80, at piping.

6. Brass pipe shall have minimum thickness of Sch 80 or extra strong.7. Galvanized pipe shall have minimum thickness of Sch 40.8. Connection joint type shall comply with vessel specification and applicable equipment specifications.
