ASTM A210 Giredhi C (ASME SA210 Giredhi C) ichubhu yesimbi yepakati-kabhoni isina musono yakanyatsogadzirirwa kushandiswa mukugadzira machubhu ebhailer uye machubhu ebhailer, anosanganisira magumo ekuchengetedza, mudhuri wechoto uye machubhu ekutsigira, uye machubhu ekudziya.
Giredhi C ine maitiro akanaka emagetsi, ane simba rekusimba re 485 MPa uye simba regoho re 275 MPa. Zvinhu izvi, pamwe chete nemakemikari akakodzera, zvinogadzira ASTM A210 Grade C machubhu akanyatsokodzera kushandiswa mukupisa kwepamusoro uye yakakwirira-. nharaunda dzekumanikidza uye inokwanisa kumirisana nekumanikidzwa kunogadzirwa nekushanda kwebhailer.
Iwo machubhu achagadzirwa nenzira isina musono uye ichave inopisa-yakapera kana kutonhora-yapera.
Pazasi pane inoyerera chati yekugadzira maitiro ekutonhora-kupedzwa seamless simbi pombi:
Saka ndeupi musiyano pakati pekupisa-kupedzwa uye kutonhora-kupedzwa seamless simbi pombi uye unosarudza sei?
Kupisa-kwaperaseamless steel pombi ipombi yesimbi inokungurutswa kana kubaiwa patembiricha yepamusoro uye mamwe maitiro uye yobva yatonhodzwa yakananga kukamuri tembiricha.Mapombi esimbi ari mudunhu rino anowanzo kuve nekusimba kuri nani uye kumwe kusimba, asi mhando yepamusoro inogona kunge isina kunaka semapombi esimbi anotonhora nekuti maitiro ekupisa anogona kutungamira kune oxidation kana decarburization pamusoro pepombi yesimbi.
Kutonhora-kupedzaSeamless simbi pombi inoreva kugadziridzwa kwekupedzisira kwepombi yesimbi nekudhirowa kunotonhora, kutenderedza kutonhora, uye mamwe maitiro pakupisa kwekamuri.Pombi yesimbi inotonhora-inopedzwa ine yakakwira dimensional kurongeka, uye yakanaka yemhando yepamusoro, uye nekuti kutonhora kugadziridzwa kunogona kuvandudza kusimba uye kuoma kwepombi yesimbi, michina yemhando yepombi yesimbi inotonhora inopedzwa kazhinji iri nani pane iyo inopisa-inopera simbi pombi. .Nekudaro, imwe huwandu hwekushushikana kwakasara hunogona kugadzirwa mukati mepombi yesimbi panguva yekushanda kunotonhora, iyo inoda kubviswa nekutevera kupisa kurapwa.
Kupisa-kupedzwa kwesimbi pombi hakudi kurapwa kwekupisa.
Kutonhora-kupedzwa kwechubhu kunofanirwa kuvharirwa, kuvharwa zvizere, kana kupisa kwakajairika mushure mekupedza kutonhora kwekupedzisira.
