EMT Pig Detector Pipeline is used to provide confirmation of the movement of pipeline pigs through a pipeline. They are normally positioned at both the pig launching and pig receiving stations and at key points along a pipeline.

Corrosion monitoring can be conducted either periodically or continuously, with the monitoring frequency being influenced by the chosen monitoring technique, the extent of corrosion on the target component, and the associated monitoring expenses. The corrosion monitoring approach dictates the speed at which corrosion rates can be assessed. For instance, while corrosion coupons typically necessitate monitoring intervals exceeding a month, resistance probes can offer more frequent readings, ranging from hours to days.

To conduct a comprehensive metal corrosion test, preparation of the metal test piece is essential. The test piece is initially weighed and then subjected to a specific duration within the test system, typically ranging from 30 to 90 days. Following this exposure period, the test piece is removed for corrosion observation, cleaning, and re-weighing.

Corrosion coupon monitoring, as one of the fundamental techniques for corrosion assessment, offers simplicity in operation and high data reliability. It serves as a vital criterion for equipment and pipeline material selection. Shengli Refinery currently employs two primary corrosion coupon monitoring methods.
