Mukudziwa chiyani za kupanga A105?

Dzina lokhazikika: zopangira zitsulo za kaboni pazigawo za chitoliro.
Chifukwa mtundu umodzi wokha wa carbon zitsulokupangaatchulidwa mu muyezo uwu, A105 amaonedwanso ngati carbon zitsulo kalasi forging.
A105 ndi code yakuthupi, yomwe ndi yachitsulo chapadera ndipo ndi chitsulo chozizira.
A105ndi chitsulo chochepa cha carbon, chofanana ndi zitsulo 20.Pali miyezo iwiri, imodzi ndi American standard ASTM A105/A105M Carbon Steel Forgings for Piping Components, ndipo ina ndi Chinese standard GB/T12228-2006 Technical Conditions for Carbon Steel Forgings for General Purpose Valves.

A105 carbon structural zitsulo
A105 ndi American ASTM standard number, ASTM A105/A105M carbon steel forgings for the pipe, and A imayimira carbon structural steel wamba.Ndi yachitsulo chapadera ndipo ndi mtundu wazitsulo zozizira.A105 ndi otsika mpweya zitsulo forging, ofanana 20 zitsulo.
Zindikirani: Mu dongosolo la mapaipi, nthawi zambiri A105 ikhoza kusintha nambala 20, koma No.Komabe, kukana kwa stress corrosion cracking (SCC) kwa A105 ndikoipa pang'ono kuposa kwa No. 20.

A105 Ndizinthu ziti zomwe zimasiyana ndi zitsulo 20
A105 ndi otsika mpweya zitsulo forging.Mpweya wa carbon structural steel uli pafupi ndi 0.05% ~ 0.70%, ndipo ena amatha kufika 0.90%.A105 ndi nambala ya American ASTM, ndipo A imayimira chitsulo chopangidwa ndi mpweya wamba.Muyeso uwu, mtundu umodzi wokha wa zitsulo za kaboni umatchulidwa, ndipo A105 imatengedwanso ngati kalasi yachitsulo ya carbon steel.A105 ndi code yakuthupi, yomwe ndi yachitsulo chapadera ndipo ndi chitsulo chozizira.A105 ndi otsika mpweya zitsulo forging, ofanana 20 zitsulo.Pali miyezo iwiri, imodzi ndi American standard ASTM A105/A105M Carbon Steel Forgings for Piping Components, ndipo ina ndi Chinese standard GB/T12228-2006 Technical Conditions for Carbon Steel Forgings for General Purpose Valves.Mpweya wa carbon structural steel uli pafupi ndi 0.05% ~ 0.70%, ndipo ena amatha kufika 0.90%.Mu dongosolo la mapaipi, nthawi zambiri A105 ikhoza kusintha nambala 20, koma No.Komabe, kukana kwa stress corrosion cracking (SCC) kwa A105 ndikoipa pang'ono kuposa kwa No. 20.
Iwo akhoza kugawidwa mu wamba mpweya structural zitsulo ndi apamwamba mpweya structural zitsulo.Imakhala ndi ntchito zambiri ndipo imagwiritsa ntchito ndalama zambiri.Amagwiritsidwa ntchito kwambiri mu njanji, mlatho, ntchito zosiyanasiyana zomanga, kupanga zigawo zosiyanasiyana zazitsulo zomwe zimanyamula katundu wosasunthika, ndi ziwalo zosafunika zamakina ndi ma weldments ambiri omwe safuna chithandizo cha kutentha.
