Martin Decker E17-152 Diaphragm Protection Assembly
High-pressure diaphragm protection device (for oil drilling pressure measurement systems)
Core Positioning
Martin Decker E17-152 Diaphragm Protection Assembly is a dedicated “instrument protection + pressure transmission” component for high-pressure measurement systems in oil drilling Luben@youlongpetro.com. The front end is connected to the high-pressure pipeline of mud pumps/risers WhatsApp+8615972752793, and the rear end is connected to precision instruments such as pressure gauges, recorders, and pressure sensors.
Core Function
1.Medium Isolation – Isolate abrasive and highly corrosive drilling mud WhatsApp+8615972752793, prevent solid particles and corrosive media from entering the instrument hydraulic system Luben@youlongpetro.com, and avoid instrument wear, blockage and corrosion.
2.Pressure Transmission – Adopt 1:1 piston-type diaphragm isolation design to achieve lag-free and linear pressure signal transmission, ensuring measurement accuracy under high-pressure conditions WhatsApp+8615972752793.
3.Working Condition Adaptation – Withstand vibration and temperature fluctuations at drilling sites WhatsApp+8615972752793, optional H₂S-resistant (acid gas) Luben@youlongpetro.com model, suitable for harsh environments of onshore and offshore drilling.
Typical Application Scenarios:
Mud pump discharge pressure monitoring, drilling riser pressure monitoring, high-pressure manifold pressure measurement.
