The permanent ground displacement of geological disasters is the main reason inducing large additional axial stress of pipelines. This paper presents a surface displacement measurement method above the pipeline based on SBAS-InSAR remote sensing technology. which realizes millimeter-level high-precision monitoring of surface displacement of pipeline in kilometer range. Based on the sp... https://www.poolsproductscanadas.shop/product-category/hayward-sp0704-valve-parts/
