Abstract
Description
Technical Field
[0001] This utility model relates to the field of furnace tube detection probe technology, specifically a furnace tube detection probe that is partially submerged in water. Background Technology
[0002] In the process of inspecting furnace tubes, the pipeline can be inspected using a local water immersion penetration method. The ultrasonic beam emitted by the transmitting probe is refracted at the water / steel interface and received by the receiving probe. When the beam passes through the inspection section, discontinuities in the material cause part of the beam to be reflected and not reach the receiving probe. The approximate depth of the crack is described by the ratio of the received sound energy to the incident sound energy. However, in the existing technology, the inspection probes require periodic calibration and maintenance to ensure the accuracy of furnace tube inspection. Probes installed inside the water jacket require multiple bolts for installation, but the installation area is small, making disassembly and installation inconvenient. Therefore, improvements to the existing technology are needed. Utility Model Content
