For the buried double metal composite pipe with frequent weld corrosion perforation, it is difficult to evaluate the remaining life through detection. Preliminary judgment of pipeline safety can be performed upon pipeline pressure test. But for double metal composite pipes that are in service with serious corrosion, there are no related standard specifications for pressure test. Through analysis, standard for pressure test of newly-established pipeline is infeasible to this kind of pipeline. Test pressure shall be reduced to make it greater than the operating pressure and lower than the design pressure. After passing pipeline nitrogen replacement, pressure shall be gradually established and tested according to the curve. Start-up shall be conducted after passing leak detection to ensure the safety of pipeline under operation pressure and small range of fluctuation.
