Problems solved by technology
In particular, during the 12th Five-Year Plan period, 54,000 kilometers of oil and gas pipelines will be built in China. According to rough calculations, more than 50,000 peel strength tests will be required to test only one patch. Using traditional testing methods is not only time-consuming and laborious, but also inaccurate test results Therefore, there is an urgent need for a portable and easy-to-operate test instrument that is more suitable for domestic use to accurately and quickly detect the peel strength of the pipeline anti-corrosion layer

Description
technical field [0001] The invention relates to a 3PE anticorrosion layer peeling strength testing machine suitable for the performance test of the peeling strength of the 3PE anticorrosion layer of pipelines. Involves general corrosion protection of metallic materials, testing not covered by other categories and technical fields of piping systems. Background technique [0002] The outer anti-corrosion layer of the pipeline is one of the most important means for long-distance pipelines to protect the pipeline from corrosion caused by the external environment. In recent years, during the excavation and detection of in-service pipelines, many corrosion phenomena of the pipe body were found due to the failure of the anti-corrosion layer. 1mm. Such rapid corrosion not only affects the quality and service life of the pipeline, but also leaves a huge safety hazard for production and operation management. Therefore, it is urgent to improve the anticorrosion quality inspection le...
