ASTM A210 Giredhi C (ASME SA210 Giredhi C) ichubhu yesimbi isina musono yepakati-kabhoni yakagadzirirwa kushandiswa mukugadzira machubhu eboiler nemafuru eboiler, kusanganisira magumo ekuchengetedza, madziro echoto uye machubhu ekutsigira, uye machubhu esuperheater.
Giredhi C ine hunhu hwakanaka hwemakanika, ine simba rekudhonza re485 MPa uye simba rekupa goho re275 MPa. Hunhu uhwu, pamwe chete nemakemikari akakodzera, zvinoita kuti machubhu eASTM A210 Giredhi C akwanise kushandiswa munzvimbo dzinopisa zvakanyanya uye dzine kumanikidzwa kwakanyanya uye anokwanisa kutsungirira kumanikidzwa kunokonzerwa nekushanda kwebhoyira.
Machubhu acho anofanira kugadzirwa nenzira isina musono uye anofanira kunge akagadzirwa nekupisa kana kuti achitonhora.
Pazasi pane chati yemafambiro ekugadzira mapaipi esimbi asina musono akagadzirwa zvinotonhora:
Saka musiyano uripi pakati pepombi yesimbi isina musono inopedzwa nekupisa neinotonhora uye unosarudza sei?
Yapera kupisaPipe yesimbi isina musono ipombi yesimbi inomoneredzwa kana kuboorwa pakupisa kwakanyanya uye mamwe maitiro uye yozotonhodzwa zvakananga kukupisa kwemukamuri. Mapaipi esimbi ari mumamiriro aya anowanzova nekusimba kuri nani uye simba, asi kunaka kwepamusoro kungasave kwakanaka semapaipi esimbi apedzwa kutonhora nekuti maitiro ekupisa anogona kutungamira mukuoxidation kana decarburization pamusoro pepombi yesimbi.
Yapera nekutonhoraPombi yesimbi isina musono inoreva kugadziriswa kwekupedzisira kwepombi yesimbi nekudhonza kunotonhora, kutenderedza kunotonhora, uye mamwe maitiro patembiricha yemumba. Pombi yesimbi inotonhora ine kurongeka kwakanyanya, uye mhando yakanaka yekumusoro, uye nekuda kwekuti kugadzirisa kunotonhora kunogona kuvandudza simba nekuoma kwepombi yesimbi, hunhu hwepombi yesimbi inotonhora hunowanzo kuve nani pane hwepombi yesimbi inotonhora. Zvisinei, huwandu hwakati hwesimba rinogona kugadzirwa mukati mepombi yesimbi panguva yekushanda kunotonhora, izvo zvinoda kubviswa nekurapa kupisa kunotevera.
Pombi yesimbi yakapedzwa nekupisa haidi kurapwa kwekupisa.
Machubhu akapedzwa nechando anofanira kunge akacheneswa zvishoma nezvishoma, akacheneswa zvizere, kana kuti akagadziriswa kupisa kwakajairika mushure mekupedza kutonhora kwekupedzisira.

Muedzo weKubata-bata
Misodzi kana maburi anoitika panguva ye12 kana 6 o'clock pachubhu yeGiredhi C ine saizi ye2.375 in. [60.3 mm] mudhayamita yekunze uye diki hazvifanirwe kutorwa sechikonzero chekurambwa.
Zvinodiwa zvakananga zvinogona kuonekwa muASTM A450, chinhu 19.

Kuoma
Giredhi C: 89 HRBW (Rockwell) kana 179 HBW (Brinell).
Pombi yega yega yesimbi inofanira kuongororwa nekumanikidzwa kwemvura kana bvunzo yemagetsi isingaparadze.
Zvinodiwa zvekuyedza zvine chekuita nekumanikidzwa kwemvura zvinoenderana neASTM 450, chinhu 24.
Zvinodiwa zvekuedza zvine chekuita nemagetsi zvisingaparadze zvinoenderana neASTM 450, chinhu 26.
Kugadzira machubhu eboiler kunodiwa kuti machubhu aya akwane zvinodiwa nehurongwa hweboiler.
Kana akaiswa mubhoyira, machubhu anofanira kumira achikura uye achitsvedza pasina kuratidza mitswe kana zvikanganiso. Kana akashandiswa zvakanaka, machubhu esuperheater anofanira kumira ese anodiwa pakuumba, kusanganisa, uye kukotama kwesimbi.
Botop Steel ikambani inogadzira mapaipi esimbi yekabhoni yakasungirirwa yemhando yepamusoro uye inopa kubva kuChina, uye zvakare inotengesa mapaipi esimbi asina musono, ichikupa mapaipi esimbi emhando yepamusoro, akaenzana, uye ane mutengo unokwikwidzana.
Kana muchida, ndapota taurai nesu, nyanzvi, online kuti muwane basa renyu!
