Premixed gas explosion pipe system was established to study the change rule of explosion
pressure and pressure rise rate of 10% methane/ air premixed gas under four condition
that no material was filled, used material was filled, new materials was filled and cleaned
materials was filled in explosive pipe. The results show that compared with the used
material and cleaned material, the average maximum explosion pressure was reduced by
21.62% and the average pressure rise rate decreased by 84.80%. The results show that
the suppression performance of used aluminum alloy explosion-proof materials improved
greatly after the used materials is cleaned
