2.TESTINGa.Hydrostotic Pressure Test of Body
1000psi(70MPa)TPHold time≥3min,no visible leakage
b.Hydrostotic Pressure Test of Sealing
One side of the plug is given 5000psi,and the other side is ventilated。The rated pressure is kept more than 3min,when the pressure released,adding up to the rated pressure,then supervise if for 3min
Follow the above step,and test the lther side.
No visible leakage at any period of stable pressure
Before pressing secondly,open the plug
