PROTECTION OF PRESSURE MEASUREMENT TRANSDUCERS Pressure measurement transducers (also called pressure sensors or transmitters) are critical in industrial processes, medical applications, and scientific research. Proper protection is necessary to ensure accuracy, reliability, and longevity of these devices. The main protective measures include shielding against environmental factors, electrical disturbances, mechanical damage, and improper handling. Therefore, protecting pressure measurement transducers is essential for ensuring accurate, reliable, and long-lasting performance. Key Protective Measures 1.Environmental Protection: Shielding against temperature, moisture, corrosion, and dust. 2.Electrical Protection: Preventing Electromagnetic Interferences, voltage spikes, and grounding issues. 3.Mechanical Protection: Guarding against vibrations, overpressure, and physical damage. 4.Installation and Maintenance Best Practices: Proper selection, calibration, and wiring. 5.Industry-Sp...
Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries
Preface
The oil and gas industry depends on steel and other metals for pipelines, storage tanks, and infrastructure. However, these metals can corrode when exposed to water or soil, which is detrimental to the integrity of pipelines and storage tanks.
This engineering book outlines the minimum requirements for anodes (high-silicon iron, graphite, magnetite) used in impressed current CP systems. It details the composition, materials, manufacturing, properties, inspection, and testing of these anodes. Additionally, it provides revised survey requirements to ensure corrosion control systems on buried or submerged structures are well-designed, operated, and maintained. The book also covers techniques, equipment, measurements, and test methods used in field applications, including the inspection of coatings in conjunction with CP for current distribution efficiency.
