CFRP repair effectiveness on compressed steel tubular members with circular cutout

Welding procedures for repairing corroded tubular structures are commonly used; however, composite material repairs becoming popular since they do not use heat sources that might cause accidents. This paper provides a detailed description of the CFRP patch repair application in steel members with circular perforation originated from prolonged corrosion process. The results experimental tests on mid-scale unrepaired damaged and repaired tubes reported. predictions maximum loads recovered proposed numerical model lie close to observed values, justifying its usage analysis cutouts when subjected axial compression. Compared perforated tubes, demonstrate substantial strength recovery tubes. value this research oil gas industry is it demonstrates feasibility kind repair, which means reduced risk production unit shorter period.
