Reducing Pressure Gauge Failures in Extreme Petrochemical Conditions

Industrial facilities, especially petrochemical plants, operate in environments where pressure gauges face constant heat, vibration, pulsation, and corrosive exposure. These conditions often cause early gauge failures, inaccurate readings, and costly downtime. EB Horsman and Son supports these challenging applications with proven solutions from Ashcroft, a manufacturer known for engineered pressure instrumentation designed for extreme service. 

Ashcroft’s field tested products help improve gauge reliability in demanding petrochemical environments through vibration resistant gauges, pressure limiting valves, and weather resistant housings that address common failure modes found during refinery assessments.

Pressure gauges can sometimes display inaccurate readings, such as indicating pressure when none is present. Situations like this highlight common concerns around gauge reliability, process visibility, and the risk of undetected instrument issues in critical applications.

• High vibration can wear down internal components and make the pointer unstable, leading to inaccurate readings.
• Pressure pulsation creates rapid pressure fluctuations that stress and distort the sensing element.
• Elevated temperatures can damage seals, discolor liquid filled gauges, warp windows, and affect accuracy.
• Moisture, corrosion, and chemical exposure may cause internal leaks, corrosion, or reduced visibility.
• Physical impacts or pressure spikes can bend sensing elements or crack windows, reducing performance.

Optimizing Gauge Performance with Advanced Vibration and Pulsation Control

Replacing traditional gauges with advanced models designed to handle vibration and pulsation helps improve accuracy and reduce maintenance issues. These upgraded designs also eliminate problems like liquid fill leakage or discoloration while simplifying gauge inventory.

Protecting Instruments with Overpressure Safety Measures

Adding pressure limiting valves provides an extra layer of protection by preventing gauges from being exposed to pressure levels beyond their limit. This helps preserve instrument integrity and supports reliable system performance.

Enhancing Durability with Weather‑Resistant Gauge Housings

Using IP66 weather resistant cases with strong acrylic windows helps safeguard gauges from moisture, environmental contaminants, and accidental window damage, ensuring clearer readings and longer service life.
