1、本科畢業(yè)設(shè)計(jì)（論文）題目：新京輸氣管道工程初步設(shè)計(jì)2013年6月13日新京輸氣管道工程初步設(shè)計(jì)摘要本輸氣管道設(shè)計(jì)項(xiàng)目是新京輸氣管道工程，管道全長(zhǎng)3441km，設(shè)計(jì)輸量每年200億立方米。通過程序RealPiep模擬仿真，確定最優(yōu)方案，并以最優(yōu)方案為例進(jìn)行設(shè)計(jì)計(jì)算。最優(yōu)方案為：末段管長(zhǎng)377，管徑1219mm，壁厚16mm，有內(nèi)涂層，共有14座壓氣站，15座清管站和114座截?cái)嚅y室，總投資487.43億元。全線采用等強(qiáng)度設(shè)計(jì)原則，管道鋼材材質(zhì)為X80鋼。目前天然氣管網(wǎng)系統(tǒng)不斷建設(shè)和相互連接成網(wǎng)，輸氣管道的設(shè)計(jì)計(jì)算、工況變化日益繁瑣，個(gè)別異常工況的出現(xiàn)必將影響輸氣管網(wǎng)的安全運(yùn)
