RISQuantitative Assessment of Damage in Buried Polyethylene Pipe Subjected to Land Subsidence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditional investigation of polyethylene pipe (PE) subjected to external loads focused only on the study of mechanical behavior or the failure judgment, but could not predict the damage evolution process. In this paper, ...
Defect Detection of Polyethylene Gas Pipeline Based on Convolutional Neural Networks and Image Processing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a method based on image recognition was proposed to detect the defects of polyethylene (PE) gas pipeline, especially the deformation due to the indentation. First, the pipeline -detection VGG (PD-VGG) model ...
Mechanical Behavior of Buried HDPE Pipe Subjected to Surface Load: Constitutive Modeling and Finite Element Method Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the Sherwood–Frost constitutive model was first used to simulate the stress response and deformation process of buried high-density polyethylene (HDPE) pipe subjected to surface load, where parameters in ...
A Lifetime Prediction Method of Pressured Gas Polyethylene Pipes by Thermal-Oxidative Aging Test and Tensile Test
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene (PE) pipes have the advantages of low weight, corrosion resistance, high impact resistance, and superior flexibility, and have been widely used for various urban gas engineering. With the increase of service ...
