Study on Explosion Suppression Technologies for Oil and Gas Pipeline

Considering potential explosion hazard of oil and gas pipeline, the technological solutions have been proposed, within certain transportation distance to fill non-metallic explosion suppression material with good chemical stability and high pressure resistance to prevent flame and explosion wave propagation in pipeline. Detonated in the high voltage ignition and chemical ignition head two types of gasoline vapor explosion conditions, spherical explosion suppression material filling stop explosion pressure propagation and realize the explosion suppression function. The results of horizontal shock tube experiment shows that there are obvious laws of blasting pressure increase drop before and after filling explosion suppression materials. The transport resistance form 150 mm diameter steel pipeline filled with explosion suppression material has also been investigated in different length and different air velocity conditions. The experimental results show that filling spherical explosion suppression material have had a limited effect in transportation capacity of pipeline.
