Three factories in Shijiazhuang is a competent welding with a small branch pipe, apparently, welding plant in Shijiazhuang welding three links is in charge of two large size, Shijiazhuang welding plant in indirect links out of the small size is the branch. in pure oxygen pipeline , The Shijiazhuang factory welded links are generally under pressure, then the oxygen plant in Shijiazhuang welding three links, greater activity; such as using different welding three links Shijiazhuang plant debris as long as the tube moves in with the flow of oxygen, due to Shijiazhuang, three welding Through changes in plant diameter, flow rate change may have caused the collision with the tube debris produced by the fire velocity changes due to production `or used for electrostatic discharge, Shijiazhuang factory welded links may cause oxygen tube fire explosion.
