RISViscoelastic and Damage Model of Polyethylene Pipe Material for Slow Crack Growth Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene (PE) pipe is widely used for oil and gas transportation. Slow crack growth (SCG) is the main failure mechanism of PE pipes. Current SCG resistance testing methods for PE pipes have significant drawbacks, ...
Burst Pressure of Glass Fiber Tape Reinforced Polyethylene Pipes With Interlayer Delamination Defect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Glass fiber tape reinforced polyethylene (GFTRP) pipes are widely used for the transportation of oil and high-pressure gas due to their good load-bearing capacity and environmental compatibility. Delamination defect is one ...
Convolutional Neural Network Based Defect Recognition Model for Phased Array Ultrasonic Testing Images of Electrofusion Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This technical brief proposes a defect recognition model to recognize four typical defects of phased array ultrasonic testing (PA-UT) images for electrofusion (EF) joints. PA-UT has been proved to be the most feasible way ...
Finite Element Analysis of Buried Polyethylene Pipe Subjected to Seismic Landslide
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene (PE) pipes are widely used in natural gas transportation systems in urban areas nowadays. As landslide caused by earthquake would cause destructive damage to buried pipes, increasing attention is attracted to ...
Study on the Allowable Temperature for Preventing Over Welding During Thermal Welding of Polyethylene Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene (PE) pipe material may degrade into lower carbon number volatiles quickly during thermal welding when the welding temperature rises up to very high temperature. However, PE may also degrade into lower molecular ...
Safety Assessment of Cold Welding Defect in Electro Fusion Joint of Polyethylene Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cold welding defect is the most common defect in electrofusion (EF) joint for connecting polyethylene (PE) pipe. In our previous study [1], the cold welding defect is successfully inspected by an eigenline method based on ...
An Improved Phased Array Ultrasonic Testing Technique for Thick-Wall Polyethylene Pipe Used in Nuclear Power Plant
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: With the application of high-density polyethylene (HDPE) pipe with thick wall in nuclear power plant (NPP), great attention has been paid to the safety of the pipeline joints, which can be assessed by phased array ultrasonic ...
Modeling the Interfacial Debonding Behavior Between Steel Wire and Adhesive
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A polyethylene pipe reinforced by winding steel wires (PSP) has been widely used in the petroleum, chemical, and water supply industries. The PSP has outstanding mechanical properties due to its unique composite structure. ...
Ultrasonic Inspection of Electrofusion Joints of Large Polyethylene Pipes in Nuclear Power Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Highdensity polyethylene (HDPE) pipe has many advantages such as good flexibility, corrosion resistance, and long service life. It has been introduced into nuclear power plants for transportation of cooling water in U.S. ...
Short-Term Mechanical Analysis of Polyethylene Pipe Reinforced by Winding Steel Wires Using Steel Wire Spiral Structural Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene pipe reinforced by winding steel wires (PSP) is a new type of polymer–matrix composite pipe that is widely used in petroleum, chemical engineering, and water supply, etc. PSP is composed of a high-density ...
