Measures to safely operate hot oil pipeline run at low - throughput condition 熱油管道低輸量的安全運(yùn)行
The two pipelines ran parallel to each other , 7 . 5 ft . apart and the maximum daily transfer was between 3 , 500 , 000 and 4 , 500 , 000 gallons of water 第二條輸水管與第一條平衡,相距7尺6寸,每天最多可運(yùn)送食水350萬(wàn)至450萬(wàn)加侖。
On the base of researching the principle of risk acceptability , some primary work has been done to the acceptability rule of city gas pipeline , on the other hand , some methods to alleviate the risk and some suggestions to make pipeline run more safely are given in the paper 在研究了風(fēng)險(xiǎn)可接受性原則的基礎(chǔ)上,對(duì)城市天然氣管網(wǎng)風(fēng)險(xiǎn)的可接受性準(zhǔn)則進(jìn)行了初步的探索,同時(shí)給出了城市天然氣管網(wǎng)風(fēng)險(xiǎn)緩解的措施和使管網(wǎng)安全運(yùn)行的建議。
At present , the distance of the pipelines running in the industry of oil refining , petrol - chemistry and electricity in china is around 500 , 000 kilometres . the majority of them last one or two decades , gradually resulting in the summit of accidents with various degrees of erosion and cracks 我國(guó)石油、化工等行業(yè)的在役油氣長(zhǎng)輸管道總長(zhǎng)約50萬(wàn)公里,其中大部分管道已使用10 ? 20年以上,出現(xiàn)不同程度的腐蝕、裂紋等缺陷,逐漸進(jìn)入事故高發(fā)期。
The system whose distance precision is within ? 00m is adapt to crude oil gathering and transferring pipelines and long distance pipelines without missing alarm and has low rate of wrong alarm . it detects the real time situation of pipeline " s running . when the system meets the si tuat ion in which the amount of leak is beyond the 1 percent of total pipeline run , it will send out alarm in a instant , give the point of leak and evaluate the extent of leak 該系統(tǒng)適用于原油集輸管線及原油長(zhǎng)輸管線,無(wú)漏報(bào),誤報(bào)率低,定位精度達(dá)到了200米,實(shí)時(shí)監(jiān)測(cè)原油管道的運(yùn)行狀態(tài),遇有大于管道輸送量的1泄漏時(shí),能夠在短時(shí)間內(nèi)聲光報(bào)警,給出泄漏位置及估計(jì)泄漏程度。
