4. Test bench is used for following operations:
- Body test (strength test and hardness test) with water, maximum test pressure up to 120 bars (1710 psi);
- Body test (strength test and hardness test) with air, maximum test pressure up to 6 bar (85 psi);
- Seat test (leakage test) with water of seat, gland seal and gasket joint, maximum test pressure up to 120 bars (1710 psi);
- Seat test (leakage test) with air, maximum test pressure up to 6 bar (85 psi).
5. Test bench makes testing of valve according to standards: API 598, DIN EN 12266, ISO 5208, ASTM E 1003.
6. Type of valve connection: flange and welded (Please specify type of connection valves according to each DN valve).
7. Size of test pressure:
- Body test (strength test and hardness test) with water: pressure test = 1,5
up to
2 x ŠN ;
- Seat test (leakage test) with water: pressure test = 1,1 x ŠN ;
- Seat test (leakage test) with air: pressure test = 6 bar (85 psi).
8. Control of testing:
- At test with water - on manometer of pump station, on falling drops in dropper on pump station and visual;
- At test with air - on manometer of pump station, on device of indicator for measurement of leakages on pump station and visual.
9. Kind of test bench: vertical.
10. Type of clamp : Unilateral clamp of valve without deformation of valve body at test:
11. Process of testing:
- Loading/unloading of valve on test bench: manual OR your crane
- Clamp of valve: automatic
- Feeding a test pressure: automatic
- Monitoring and measurement of test results: manometer, visual.
12. Control panel has all necessary devices for measurement and control of testing (Please be informed that control panel is included in test bench).
Source of pressure (pump station) is included in test bench. Pump station used for creation of water and air pressure, for filling water of valves, for stepless control of outlet pressure, for automatic support of outlet pressure. Name of model is PGS.
13. All metal details contacting with water are protected from corrosion.
14. Maximal size (diameter) of testing tables: 780 mm
Maximal weight of valve: 2100 kg
15. Test medium:
- Water (Demands for water: in 100 cubic centimeters of water should contain no more than 400 particle a size from 50 up to 100 microns)
- Air from factory pneumatic mains (Demands for air: a size of a hard particle no more than 40 microns).
16. Ambient temperature: +1 up to +40 Ń °.
17. Overall dimensions
• Test bench without pump station 1530 õ 1350 õ 1200 mm
18. Weight
• Test bench without pump station 1950 kg
19. You must need for test bench of following:
- Inlet compressed air with pressure 4 up to 6 bar (57 up to 85 psi);
- Inlet water with pressure 1,5 bar (21 psi);
- We would like to recommend for you to have of Circulation water supply system volume 1000 liters, 1500 liters, and 5000 liters. |
