Ultrasonic Testing of Forged Steel Products
Introduction
Ultrasonic testing (UT) is a non-destructive inspection method used to locate and identify discontinuities in forged steel products. In UT, sound waves are used to detect hidden defects in the material and provide a detailed cross-section ......
GB 8650-88 Test method for resistance to stepped cracking of pipeline steel
GB 8650-88 provides a method for a fracture test that assesses the ability of steel pipelines to withstand different conditions. This test involves a pipe filled with water, the pressure of which is gradually increased. At each stage, the pipe is blocked off, and then examined afterwards to see if......
