Gas Pipeline Welding Defects at Joseph Avent blog

Gas Pipeline Welding Defects. aiming at the problems of low target detection accuracy and high leakage rate of the current traditional weld surface. this paper discusses on (i) pipeline failures (ii) defects in pipeline (iii) dents & assessment of dents (iv) cracks. Incomplete penetration refers to the gap between base materials caused by insufficient arc welding; the experimental results show that the diagnostic accuracy of the method can reach 96% with high reliability and. welding can also be used for the repair of corrosion or mechanical damage through the installation of a repair sleeve. the girth weld defects of oil and gas pipelines can be roughly classified into planar defects, volumetric defects and irregular shape defects. Planar defects include incomplete penetration, lack of fusion, crack and undercut, etc. girth weld defects (crack, lack of penetration, lack of fusion, and edge nibbling) can cause pipeline cracking. the defects that originate in the underground gas pipelines can be classified into corrosion, erosion, crack, pinhole, shallow.
