目前,普通钢制压力容器的声发射检测的应用已非常广泛,且技术已比较成熟,沧州欧谱但应用声发射技术检测铝制或不锈钢制的压力容器的水压试验监测还比较少。这两类容器在某些特定范围内的应用比较广泛,其相应的检测及监测也是非常重要的。本文主要讨论了铝制及不锈钢制压力容器试验件的试验性声发射检测,目的在于探索这两类容器的声发射特征,使其可应用于实际在役的容器检测中。 THEACOUSTICEMISSIONMONITORINGOFTHEALUMINUMANDSTAINLESSSTEELPRESSUREVESSELDURINGHYDRAULICPRESSURETESTING TangZhiwen1SunWei1KongFangong2LuoHaiqiang3 (1EngineeringDesign&ResearchInstituteThesecondArtilleryCorpsofP.L.A,Beijng100011)锌层测厚仪http://www.xincengcehouyi.com (2ShanghaiJiaotongUniversity,Shanghai200030) (3PhysicalAcousticsCorp.BeijngOffice,Beijng100101) Abstract:Atpresent,acousticemissionexaminationofcommomsteelpressurevesselsisalreadyextremelywidespread.Andthetechnologyisalreadyquitemature.Butitisalsofewthattheacousticemissiontechnologymonitoringthealuminumandstainlesssteelpressurevesselsduringhydraulicpressuretesting.Twokindsofthesevesselshavebeenusedquitewidespreadincertainareas,sothecorrespondingexaminationandmonitoringisextremelyimportant.Thisarticlemainlydiscussedtheacousticemissionmonitoringofaluminumandstainlesssteelpressurevesselstofindoutacousticemissioncharacteristicsofthesetwokindsofvessels,andinturntobeappliedintheexaminationofpressurevesselsinservice.
