The back seal test panel is designed to allow a controllable pressure of between 10-300 bar at the output connection.
The pressure supplied to the unit is controlled via a relief valve connected to the line which can be manually adjusted prior to subsea deployment. Pressure is monitored via a subsea rated gauge and a port is also supplied to allow for connection to a customer-supplied pressure transducer, should it be required. A hydraulic operated ball valve is fitted to allow the pressure to be locked in the output line.
The Specialist Offshore Services Back Seal Test Panel design allows controllable and safe subsea pressure testing across wide range of pressures, standard units can be set for relief pressures of 50 – 6000psi.
The pressure set at the relief, limits the test pressure supplied. In order to consequently ensure peace of mind, confidence and repeatability, Specialist Offshore Services only use industry-leading relief valves. Of course, clients accuracy requirements dictate the relief valve chosen. Equally important is that, prior to subsea deployment, the client can manually adjust the relief on deck. Versions of this panel are available, covering the 50-6000psi range. Gauges can be chosen to suit the pressure test. This ensures monitoring can be completed easily and accurately.
