High pressure boiler chubhu inogadzira kutengesa
(1) Nyika huru dzekutumira machubhu iJapan neGermany. Madimikira ezvigadzirwa zvinowanzotengwa kunze kwenyika ndeye 15914.2mm; 2734.0mm; 219.110.0mm; 41975mm; 406.460mm, zvichingodaro. Izvo zvishoma zvakatemwa i31.84.5mm, uye kureba kunowanzo 5 ~ 8m.
(2) Munyaya yekutora kunze kwenyika, ST45 isina musono boiler machubhu anounzwa kubva kuMannesmann steel pipe plant kuGermany akawanikwa aine hurema hwemukati hunodarika mirau yechirimwa uye zviyero zveGerman iron and Steel Association.
(3) Alloy simbi mapaipi anotengeswa kubva kuGermany anonyanya 34CrMo4 uye 12CrMoV. Iri rudzi rwepombi yesimbi ine yakanaka-yepamusoro-tembiricha mashandiro uye inowanzoshandiswa sesimbi pombi kune yakakwirira-tembiricha bhailer.
(4) Kune akawanda alloy mapaipi akatengwa kubva kuJapan, ane zvirevo zve426.012mm 5 ~ 8m; 152.48.0mm12m; 89.110.0mm6m; 101.610.0mm12m; 114.38.0mm6m; 127.08.0mm9m, zvichingodaro. Shandisa Japanese maindasitiri mwero jisg3458, uye simbi giredhi is stpa25. Iyi pombi yesimbi inowanzoshandiswa sekutsigira superalloy pombi.
High quality carbon structural simbi, uye simbi mamakisi ari 20g, 20mng uye 25mng; Alloy structural simbi 15mog, high pressure pombi.
20mog, 12crmog, 15CrMoG, 12CR2MOG, 12crmovg, 12Cr3MoVSiTiB, nezvimwewo; Pamusoro pekuve nechokwadi chekugadzirwa kwekemikari uye zvivakwa zvemuchina, 1Cr18Ni9 uye 1cr18ni11nb mapombi akanyanya-kudzvanywa anowanzo shandiswa musimbi ine ngura isingadzivirirwe nesimbi ichave iri pasi pe hydrostatic bvunzo, flaring uye flattening bvunzo imwe neimwe. Mapombi esimbi achaunzwa mumamiriro ekupisa.
Mukuwedzera, pane zvimwe zvinodikanwa zveiyo microstructure, saizi yezviyo uye decarburization layer yepombi yesimbi yakapedzwa. Seamless simbi pombi ye geological kuchera uye petroleum drilling control; Kuti uongorore dombo repasi pevhu, mvura yepasi, oiri, gasi rechisikigo uye zvicherwa zviwanikwa, madhiri ekuchera anoshandiswa kuchera matsime.
Oiri uye gasi kushandiswa hazviparadzaniswe kubva pakuchera. Seamless simbi pombi ye geological drilling control uye kuchera oiri ndicho chikuru midziyo yekuchera, kunyanya inosanganisira yepakati pombi yekunze, pombi yemukati yepakati, casing, pombi yekuchera, nezvimwe.
Sezvo pombi yekuchera ichida kushanda pakadzika kwezviuru zvemamita, mamiriro ekushanda akaomarara, pombi yekuchera inotakura kushushikana kwekumanikidzana, kudzvanya, kukotama, kudhonzwa uye kusarongeka kwemutoro, uye zvakare inopfekwa nemadhaka nedombo. . Naizvozvo, pombi inofanira kuva nesimba rakakwana, kuoma, kusapfeka uye kuoma kwesimba, Simbi yepombi yesimbi inomiririrwa ne "DZ" (Geological Chinese Pinyin prefix) pamwe nenhamba yekumiririra simbi inobuda poindi. Iyo inowanzoshandiswa simbi mamakisi 45mnb uye 50Mn ye dz45; 40Mn2 uye 40mn2si yedz50; 40mn2mo uye 40mnvb yedz55; 40mnmob yeDZ60 uye 27mnmovb yedz65.
Mapaipi esimbi anounzwa mumamiriro ekupisa.
Pombi isina musono yepombi yechoto, pombi yekupisa yekupisa uye pombi mune petroleum yekunatsa. Inowanzo gadzirwa nepamusoro-soro kabhoni simbi (10, 20), alloy simbi (12CrMo, 15CrMo), kupisa-resistant simbi (12cr2mo, 15cr5mo) uye Stainless simbi (1Cr18Ni9, 1Cr18Ni9Ti). Pamusoro pekugadzirwa kwekemikari uye kwakasiyana-siyana michina yepombi yesimbi, zvinodikanwa zvakare kuve nechokwadi che hydrostatic, flattening, flaring uye mamwe bvunzo, pamwe nehupamhi hwepamusoro uye kuyedza kusaparadza. Mapombi esimbi achaunzwa pasi pekupisa.
Mhando dzese dzesimbi dzesimbi dzinopisa-yakakungurutswa uye inotonhora-yakakungurutswa Stainless simbi mapaipi anoshandiswa zvakanyanya mupetroleum nemakemikari emidziyo pombi uye simbi isina simbi zvimiro zvezvinangwa zvakasiyana. Pamusoro pekuve nechokwadi chekuumbwa kwemakemikari uye mekiniki zvivakwa, ese mapombi esimbi anoshandiswa kutakura fluid pressure anofanirwa kuve akakodzera muyedzo yehydrostatic. Mapombi esimbi akasiyana-siyana anozovimbiswa zvinoenderana nemamiriro akatarwa.
High pressure seamless simbi pombi rudzi rwepombi isina musono. Nzira yekugadzira ndiyo yakafanana neyepombi isina musono, asi pane zvinodiwa zvakasimba zvegiredhi resimbi rinoshandiswa mukugadzira pombi yesimbi. Zvinoenderana nekupisa kwesevhisi, yakakamurwa kuita general boiler chubhu uye yakakwirira-kumanikidza boiler chubhu.
① Iyo tembiricha yebasa repamusoro-kudzvanywa isina musono pombi iri pazasi 450 ℃, uye pombi yemumba inonyanya kugadzirwa neNo. 10 uye No.
②High pressure seamless simbi mutopota kazhinji tembiricha uye high pressure mamiriro. Iyo pombi ichave yakasvibiswa uye yakasvibiswa pasi pekuita kwepamusoro tembiricha flue gasi uye chiutsi. Iyo pombi yesimbi inodiwa kuti ive nesimba rakasimba rinogara, yakakwira anti-oxidation uye corrosion performance uye yakanaka kugadzikana kwemaitiro.
① High pressure seamless simbi pombi inonyanya kushandiswa kugadzira pombi yemadziro emvura, pombi yemvura inofashaira, pombi inopisa inopisa, pombi inopisa inopisa ye locomotive boiler, pombi hombe uye diki yeutsi uye arch zvidhinha pombi.
② High pressure seamless simbi pombi inonyanya kushandiswa kugadzira superheater pombi, reheater pombi, air duct, main steam pombi, etc. yehigh-pressure uye Ultra-high-pressure boilers muzvidyarwa zvemagetsi.
