WebAug 1, 2016 · A choke bean used in an oil-gas field has catastrophically failed during operation. It is shown that that the damage has been caused by leakage of the corrosive and abrasive drilling fluid. WebWhen this occurs, the bubbles collapse and turn back into liquid. If the P 2 pressure remains below the vapor pressure, the liquid will boil and flash to vapor as it passes through the valve and remain a vapor as it exits (figure 3). Figure 3. This graph shows a typical pressure curve of a flashing liquid passing through a control valve. sandy bay busselton accommodation
