Mapombi esimbi efetereza yekemikari anonyanya kushandiswa kugadzira yakakwirira-mhando kabhoni structural simbi, alloy structural simbi uye stainless heat-resistant simbi yakakwira-kudzvanywa isina musono pombi dzemapombi eboiler ane kumanikidzwa kukuru uye pamusoro pemachubhu uye aya machubhu ebhailer anoshanda pasi pekupisa kwakanyanya. uye high pressure, uye machubhu achave oxidized uye corroded pasi pechiito chepamusoro-tembiricha flue gasi uye chiutsi.Naizvozvo, machubhu esimbi anodiwa kuti ave nesimba rinogara rakareba, kukwirira kweoxidation kuramba, uye kugadzikana kwakanaka kwesangano.Magiredhi esimbi anoshandiswa ndeaya: emhando yepamusoro kabhoni structural simbi mamakisi ari 20G, 20MnG, 25MnG;Alloy structural simbi mamakisi 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, nezvimwewo;Iyo yakajairwa 1Cr18Ni9 uye 1Cr18Ni11Nb yakakwira-kudzvanya boiler machubhu akagadzirwa nengura uye asingapise kupisa achave ari pasi pe hydrostatic bvunzo, flaring uye flattening bvunzo imwe neimwe mukuwedzera kune kuve nechokwadi kuumbwa kwemakemikari uye michina zvivakwa.Iyo yakakosha machubhu esimbi emakemikari fetiraiza achaunzwa mumamiriro ekupisa.

Nzvimbo inoshanda

Iyo yakakosha pombi yefetereza (GB6479-2000) ndeyepamusoro-mhando kabhoni structural simbi uye alloy simbi isina musono simbi pombi inokodzera makemikari emidziyo uye pombi ine tembiricha yekushanda ye - 40 ~ 400 ℃ uye kushanda nesimba kwe10 ~ 30Ma.

High pressure alloy pombi yefetereza midziyo (GB6479-2000) imhando yepamusoro kabhoni structural simbi uye alloy simbi musono simbi pombi yakakodzera makemikari midziyo uye pombi pamwe kushanda tembiricha ye - 40 ~ 400 ℃ uye kushanda kumanikidzwa 10 ~ 30Ma.

Sumo yekugadzira

(1) Nzira yekugadzira:

①Tembiricha yekushandisa yemapombi esimbi yefetereza iri pazasi 450 ℃, uye mapaipi epamba anonyanya kugadzirwa nekupisa kwakakungurutswa kana kutonhora kudhonzwa 10 # uye 20 # carbon bonded simbi pombi.

②Iyo pombi yakakosha yesimbi yefetereza inowanzo shandiswa pasi pekupisa kwakanyanya uye kudzvanywa kwakanyanya, uye pombi inozoiswa oxidized uye yakasvibiswa pasi pechiito chepamusoro-tembiricha flue gasi uye mhute yemvura.Iyo pombi yesimbi inodiwa kuti ive nesimba risingaperi, yakakwirira oxidation uye kusagadzikana kwekuora, uye kugadzikana kwakanaka kwesangano.

(2) Chinangwa:

①Mapombi esimbi emakemikari fetiraiza anonyanya kushandiswa kugadzira pombi dzemadziro emvura, pombi dzemvura dziri kufashaira, pombi dzinopisa kwazvo, pombi dzinopisa kwazvo dzemabhoilers emagetsi, pombi hombe nediki dzeutsi uye mapaipi ezvidhinha.

②Pombi yesimbi inonyanya kushandiswa kugadzira fetiraiza inonyanya kushandiswa kugadzira pombi inopisa, pombi inodzoreredza, pombi yemhepo, pombi huru yehutsi, nezvimwe zve-high-pressure uye ultra-high pressure boiler.
