Large Variable Diameter Magnetic Leakage Detector

۴۰% of the deformation capacity, greatly expanding the range of detectable pipelines; In pipelines that can carry out routine testing, due to the limited deformation capacity of the testing equipment (general deformation of 15% 0D or even less), different diameter pipelines need to strictly select the corresponding diameter of the detection equipment for the operation of the full-diameter coverage (159mm-1422mm) detection equipment specifications reached more than 20 kinds, the use of the Shenyang Shenyang Instrumentation Academy’s multi-caliber adaptive pipeline detection technology, the implementation of large diameter pipeline detection operations become possible. Each specification detector to meet at least three diameters of pipeline testing, for the testing party or pipeline operators to save a lot of cost.

Shenyang Instrumentation Academy of large diameter magnetic leakage detection equipment breaks through the traditional detector with a bowl sealing thinking, using umbrella skeleton fitted with a high degree of folding polyurethane shaped parts, to achieve a continuous formation of sealing and centerline coupling in different diameter pipelines. It carries a large deformation of the magnetic circuit structure, and the arrangement of the interlaced magneto-electric composite heterogeneous field multifunctional sensors, to realize the pipeline defect detection of the whole cross-section.
