Pipeline Rupture
When faced with this situation pipeline rupture, firstly, we need to adopt security measures: all vents open underground pipelines and electric fan for ventilation agile immediately, if the pipeline is gasoline, then it is transpiration character outside the big, the risk of fire or explosive attack corresponding progress. Years of practical experience has shown that in the next room temperature and pressure can be agile kg gasoline transpiration between 14 cubic meters of gasoline vapor. And transpiration from the gasoline out of the gasoline vapor mixed with air, explosive hydrocarbon gas mixture multiplied.
Because once transpiration, then it's a large amount of gasoline vapor collection does not rise at all stores nearby, constitute dozens of square meters of area to cover the entire job the whole region, it will immediately cause once touch fire burning or blasting. Under normal conditions, the concentration of gasoline burst limit is higher. According to their foreign counterparts proved mixed gasoline vapor and air to reach a ratio of more than a moment, then poisoning can lead to the appearance of gasoline vapor will be very serious; share of ten percent of the time, within an hour, due to the impact of people's eyes and tears; increased to twelve percent, the better half of a class hour eyes, nose, and throat due to the effects become particularly sad, dizzy and rendered blind and performance; when the concentration reaches 17 percent, in and drunkenness would like fifteen minutes, if not hours of staff adopted this approach may appear to shock and death situation; arrival of two to one when the share of oil and gas division, if there is a touch that will soon be paralyzed and staff died. Therefore, in order to ensure the safety of operating personnel, as well as to the safety of underground pipeline repair of underground pipelines agile immediately ventilation is necessary.
Finishing oil spills, sand burial ground quickly recovered underground pipeline spill to clean the entire floor with mulching with sand save and repeat cleaning more than twice, and then save the sand-rich oil spill moved to a small outdoor sand screening machine, spread evenly on the ground floor and a half centimeters save sand. The straight seam steel pipe eradicate residual oil left clean, do not throw, can be recovered and reused. The reason is due to the general leak under long-term use condition, straight seam accumulate a lot of water vapor inside the pipe, steel pipe and the occurrence of rust corrosion effect, a considerable period of time and then in the gas impact, wall thinning, end crack.
