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 o se mea faʻapitoa foʻi, lea e patino i le sila faʻapitoa ma o se uamea 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 Faʻapitoa 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 o le Numera 20 e le mafai 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.
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 vasega uamea kaponi o le faʻamalosi.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 Faʻapitoa 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 le faiga o paipa, 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 avega mamafa, ma vaega le taua faʻainisinia ma uelo lautele e le manaʻomia togafitiga vevela.
