[摘要]  目前海底雙層管道面臨著高溫高壓以及高膨脹量等挑戰(zhàn)，為了解決相應(yīng)問題，結(jié)合ABAQUS及AUTOPIPE兩種軟件構(gòu)建相應(yīng)的模型，對(duì)雙層管進(jìn)行模擬計(jì)算。利用ABAQUS軟件對(duì)雙層管進(jìn)行膨脹量的計(jì)算以及Bulkhead對(duì)于雙層管的力學(xué)性能的影響分析。在ABAQUS計(jì)算基礎(chǔ)之上，利用AUTOPIPE軟件對(duì)膨脹彎進(jìn)行模擬，并對(duì)膨脹彎的各個(gè)參數(shù)進(jìn)行敏感性分析，根據(jù)各個(gè)參數(shù)的變化規(guī)律，提出膨脹彎的“黃金”布置準(zhǔn)則。

Abstract: The high temperature and high pressure (HTHP) condition has been getting more common in recent field developments. Pipe-in-pipe (PIP) pipeline systems have been widely employed to scope this HTHP situation. Structural complexity of PIP pipeline type brings challenge in design phase. This paper describes proposed calculation approaches based on general and specialist finite element software ABAQUS and AUTOPIPE respectively. ABAQUS based method calculates the thermal expansion of PIP pipeline and AUTOPIPE based models were used to carry out spool analysis and design. Parametric study has been conducted on effect of selected key factors on spool design. Based on the results from the study, “Golden Rules” have been suggested for spool design.

Keywords：pipe-in-pipe； AUTOPIPE /ABAQUS；spool； high pressure high temperature
