Notes
- Ring joint gasket dimensions conform to ASME B16.20 (not covered in this summary).
- Use Class 600 lb in sizes NPS 1/2 to NPS 31/2 for Class 400 lb.
- Use Class 1500 lb in sizes NPS 1/2 to NPS 21/2 for Class 900 lb.
- Tolerances are as shown in the table below.
1 The height of the raised portion is equal to the depth of groove dimension L, but is not subject to the tolerances for L.
2 Ring joints with lapped flanges in Classes 300 lb and 600 lb use R30 instead of R31.
