Effect of silica sand filler on mechanical properties of epoxy grout for composite repair of steel pipelines

Oil and gas pipes are vulnerable to failure initiated by corrosion because of their operating pressure under adverse conditions. A composite repair assembled around the pipe with a small gap that is then infilled with epoxy grout is considered a suitable option for repairing corroded pipelines. This...
