BPRV Design and Development • Designed as: A non-reclosing ‘ reclosable’ Pressure Relief Device – An alternative non-reclosing Pressure Relief Device • Usually Rupture Disks. – An alternative to reclosing Pressure Relief Valves • API series and pilot operated valves. – To Provide in-line Pressure or Vacuum relief • Easy to upgrade a rupture disk position • Installed directly between companion flanges – To offer quick and simple External reset, without opening flanges/piping! 2

Buckling Pin Valves - Applications ESP Pump Protection BPRV Closed – Fluid pumps freely BPRV Open – Flow line blocked, to Oil/Water separator flow recirculates to well casing Advantages of the BPRV in this Application • Pump is protected by a mechanical fail safe device • Well oil/water column is maintained even with a blocked outflow pipe, reduces the potential of the well drying out and needing to be re drilled • BPRV latches when open, eliminates chattering thus flow and pressure to pump are constant, reduces system hysteresis and therefore improves plant reliability 19

She ll T ub e He a t e xc ha ng e r The BPRV has been used to protect the shell side due to the fast response time . Reducing the downtime compared to the rupture disks. 20

The Buckling Pin API-Series Relief Valve BPAV 21

The Buckling Pin API-Series Relief Valve – BPAV* • The First API Series Buckling Pin Relief Valve • Same body Configuration as API Safety Relief Valves • Piping Dimensions are API Standard *US & International Patents Pending 22

The Buckling Pin API-Series Relief Valve • Buckling Pins are installed with cap-screw • Only takes minutes to reset! • The Calibrated Pin certifies the device!!! • Operate to 90% of set pressure with no simmering! • No orifice, high capacity 23
