查询词典 explosion-proof

To avoid loss of drilling tools and even well abandonment due to downhole fire or explosion during air drilling in pay zones, we developed a novel downhole fire or explosion prevention sub, a kind of downhole tool made of low meltingpoint alloy, designed to shield off oxygen so as to put out fires. This sub is connected to the upper part of dill bit.
