: The standard applies to:

Permanent welded connections designed to eliminate leak paths in volatile systems.

The standard defines how manufacturers must determine the Pressure-Temperature (P-T) ratings for instrument valves. These ratings are heavily dependent on the body material (e.g., 316 Stainless Steel, Carbon Steel, Monel) and the sealing materials (PTFE, PEEK, Graphite). 2. Design and Construction : The standard applies to: Permanent welded connections
