【摘要】 壓力容器安全系數(shù)與材料參數(shù)緊密相關(guān),確定材料許用應(yīng)力值時(shí),需要同時(shí)考慮材料抗拉強(qiáng)度和屈服強(qiáng)度更為合理;奧氏體不銹鋼材料具有非常好的應(yīng)變強(qiáng)化能力和韌性,為充分發(fā)揮奧氏體不銹鋼材料優(yōu)良性能,選取奧氏體不銹鋼材料許用應(yīng)力值時(shí),需要特殊考慮。壓力容器安全系數(shù)的選取建立在經(jīng)驗(yàn)基礎(chǔ)上,在保障壓力容器安全性前提條件下,為節(jié)省材料和降低成本,隨著理論研究深入和科學(xué)實(shí)驗(yàn)的進(jìn)步,壓力容器安全系數(shù)有所降低,這是科學(xué)設(shè)計(jì)和實(shí)用成功經(jīng)驗(yàn)結(jié)合的結(jié)果。
【英文摘要】 The safety factor of pressure vessel is closely related to material parameters.It is more reasonable to consider both the tensile and yield strengths for material allowance stress.Austenitic stainless steels should be considered specially to use their excellent strength properties of their strain strengthening effect.The safety factor of pressure vessels is based on practical experience and can be reduced to save materials by controlling pressure vessel safety with the development of pressure vessel techniq...

【正文快照】 0引言壓力容器廣泛用于工業(yè)領(lǐng)域及日常生活領(lǐng)域,一旦破壞,往往造成災(zāi)難性事故。為確保公眾安全,應(yīng)用科學(xué)技術(shù)和使用經(jīng)驗(yàn),世界各國(guó)制訂了壓力容器標(biāo)準(zhǔn),并通過(guò)法規(guī)等形式強(qiáng)制執(zhí)行。合理選取材料許用應(yīng)力值是保障壓力容器安全、合理使用的科學(xué)基礎(chǔ)。1914年,美國(guó)制定了世界上第一部
