We pay much attention in Test process:
(1) Shell Hydrostatic Test
ANSI B 16.34 Section 7.1 | ||
Valve Size NPS | Test pressure | Test Time. Sce |
Below DN50 | 1:5 times the 100°F | 15 Sce |
DN65~DN200 | Rating of ANSI Class | 60 Sce |
Up DN250 | Max. Operating Pressure | 180 Sce |
Test pressure should be above 1.5 times than the valve's Max work pressure (100F) |
(2) Seal Hydrostatic Test
The pressure should be more 1.1 times than working pressure by seal hydrastatic test
ANSI B 16.34 Section 7.2 | ||
Valve Size NPS | Test pressure | Test Time. Sce |
below DN50 | 1:1 times the 100°F | 15 Sce |
DN65~DN200 | Rating of ANSI Class | 30 Sce |
above DN250 | Max. Operating Pressure | 60 Sce |
Test pressure should be more 1.5 times than the valve's Max work pressure (100F) | 180Sce |
(3) Seal Air Test
Seal air leakage test is based on 80PSIG(6kgf/cm2) inert-gas or the air reach the test pressure, then close the valve. after that check the valve whether it is leakage or not.
