RISConvolutional 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 ...
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 ...
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. ...
