A leaf spring caliper is a device used to detect the geometry and defects of inner wall oil gas pipelines. The detection principle involves installing strain gauges on detecting arm, which can be bent elastically. gauge signal connected voltage-detecting equipment pipeline through voltage signal. This has advantages high accuracy small structure size. However, arm works via contact detection, will worn out when working, thus reducing accuracy. paper establishes wear model constructs test system based model. simulates between material 51CrV4 (ISO 683-2-2016) L555Q 3183:2012). By changing coating such as nickel-phosphorus coating, epoxy acrylic resin or polytetrafluoroethylene (PTFE) pattern explored experimental results are analyzed summarized select most suitable material. polynomial fit data, followed by Reye–Archard fit, was performed finally derive function for springs with different materials. prediction algorithm predict detector extended length calibrated. show that average error predicted data actual observed in accordance expectations. Therefore, its corresponding applied correction improve calipers.

In recent years, with the increasing construction mileage of oil and gas pipelines (OGPs), aging problem OGPs has become increasingly prominent, so, ensuring safety is great significance. addition, OGP transportation also an important component pipeline integrity. Therefore, to ensure transportation, regular inspections should be carried out. During this process, defects in measured wall thickness information recorded provide a basis for subsequent repair or replacement. This study analyzes literature on testing reviews approximately eighty articles. Based these articles, we summarize types common review basic principles various non-destructive methods pipelines, including electromagnetic acoustic transducer inspection, magnetic flux leakage testing, ultrasonic eddy current testing. We detailed introduction applications innovative based above inspection methods. Finally, analysis outlook future research focus technology are presented. suggests that different detection used defects, such as using method internal natural pipelines.
