Application Design Model of Damaged Steel Pipes. Repair By Composite Materials

      Аннотация: Application Design Model of Damaged Steel Pipes by using composite materials for oil and gas industry.This needs to carry out experimental and analytical study to investigate the stress fields, failure pressure, thickness of repair laminate, damaged area and other related parameters on the performance of the repaired pipe.This book presents the results of research studies carried out in the Arabian Gulf Oil Company (AGOC) and in the laboratory of the Faculty of Engineering at Garyounis( Benghazi) University.NEW TO THIS Book A carbon steel bolted clamp and screwed clamp were used to clamp the pipe around the defected area to minimize the delamination effect and stop the leakage of water during the tests of the pipes. A special rig was designed to carry out pressurized tests on the repaired pipes. A model based on fracture mechanics and composite lamina theory was developed to predict stress-strain behaviour at defect region.
