川氣東送管道工程用Φ1 016 mm×26.2 mm感應(yīng)加熱彎管的性能分析

Property Analysis on Φ1 016 mm × 26.2 mm Induction Heat-processed Elbows Used for Sichuan-East Gas Pipeline Project

摘要: 從對(duì)國(guó)內(nèi)某彎管廠生產(chǎn)的川氣東送管道工程用Φ1 016 mm×26.2 mm感應(yīng)加熱彎管及其母管的主要理化性能進(jìn)行的分析比較中發(fā)現(xiàn),感應(yīng)加熱彎管及其母管的主要性能均值明顯高于該管道工程技術(shù)標(biāo)準(zhǔn)的要求;所制得的彎管較母管強(qiáng)度下降,韌性上升,塑性略有增加;彎管不同部位的性能變化也有一定的差異。

Abstract: Comparatively analyzed are the main physiochemical properties of both the Φ1 016 mm×26.2 mm induction heat-processed elbows used for Sichuan-East Gas Pipeline Project as manufactured by a domestic elbow maker and the mother pipes thereof.The result shows that the major property mean values of the elbow and the mother pipe are better than the applicable criteria for the project.Compared with the mother pipe,the elbow's strength is reduced,while its toughness is increased,and the plasticity is increased,too,but slightly.Also identified is that the property changes of different parts of the elbow vary.
