O le a se mea e te iloa e uiga i le faʻailoga A105?

Igoa masani: u'amea u'amea forgings mo vaega paipa.
Aua e na o le tasi le ituaiga o carbon steelfa'ameameao loʻo faʻamaonia mai i lenei tulaga, A105 o loʻo faʻapea foʻi o se faʻailoga uamea carbon mo le faʻamalosi.
O le A105 foi o se mea faʻapitoa, lea e patino i le sila faʻapitoa ma o se uʻamea malulu malulu.
A105o se u'amea uamea maualalo forging, tutusa ma 20 sila. E lua tulaga, o le tasi o le American standard ASTM A105 / A105M Carbon Steel Forgings mo Piping Components, ma le isi o le Chinese standard GB / T12228-2006 Tulaga Faʻatekinisi mo Carbon Steel Forgings mo Valves Faʻamoemoega Lautele.

A105 carbon fausaga uamea
A105 o le American American Standard Numera, ASTM A105/A105M carbon steel forgings mo vaega paipa, ma le A o loʻo faʻatusalia le carbon structural steel. E patino i uamea faapitoa ma o se ituaiga o sila malulu. A105 o se u'amea maualalo kaponi forging, tutusa ma 20 sila.
Faʻaaliga: I totonu o le pipeline system, e masani lava A105 e mafai ona sui le Numera 20, ae le mafai e le Numera 20 ona suia atoa le A105, aua o le eseesega o le malosi e tele lava. Ae ui i lea, o le malosi o le corrosion cracking (SCC) tetee a le A105 e sili atu le leaga nai lo le Nu. 20.

A105 O a mea e ese mai le 20 sila
A105 o se fa'ameamea uamea maualalo. O le carbon anotusi o carbon structural steel e uiga i le 0.05% ~ 0.70%, ma o nisi e mafai ona maualuga e pei o le 0.90%. O le A105 o le numera masani a Amerika ASTM, ma o le A o loʻo faʻatusalia le uamea faʻapipiʻi masani. I lenei tulaga, e naʻo le tasi le ituaiga o faʻamaʻi uamea carbon ua faʻamaonia, ma o le A105 o loʻo taʻua foi o se faʻailoga uamea carbon mo le faʻamaʻiina. O le A105 foi o se mea faʻapitoa, lea e patino i le sila faʻapitoa ma o se uʻamea malulu malulu. A105 o se u'amea maualalo kaponi forging, tutusa ma 20 sila. E lua tulaga, o le tasi o le American standard ASTM A105 / A105M Carbon Steel Forgings mo Piping Components, ma le isi o le Chinese standard GB / T12228-2006 Tulaga Faʻatekinisi mo Carbon Steel Forgings mo Valves Faʻamoemoega Lautele. O le carbon anotusi o carbon structural steel e uiga i le 0.05% ~ 0.70%, ma o nisi e mafai ona maualuga e pei o le 0.90%. I totonu o le pipeline system, e masani lava A105 e mafai ona sui le Numera 20, ae le mafai e le Numera 20 ona suia atoa le A105, ona o le eseesega o le malosi e tele lava. Ae ui i lea, o le malosi o le corrosion cracking (SCC) tetee a le A105 e sili atu le leaga nai lo le Nu. 20.
E mafai ona vaevaeina i le carbon structural steel masani ma le maualuga o le carbon structural steel. E tele lona faʻaoga ma faʻaaogaina se aofaiga tele. E masani ona faʻaaogaina i nofoaafi, alalaupapa, galuega faufale eseese, gaosiga o vaega uʻamea eseese o loʻo tauaveina le mamafa o avega, ma vaega le taua faʻainisinia ma uelo lautele e le manaʻomia togafitiga vevela.
