Yepakati uye yakaderera kumanikidza simbi pombi yakagadzirwa muChina
(1) Gb3087-82 machubhu esimbi asina musono epasi uye epakati anomanikidza boilers. Tensile bvunzo ichaenderana neGB / t228-87, hydrostatic bvunzo ine GB / t241-90, flattening bvunzo ine GB / t246-97, flaring bvunzo ine GB / t242-97 uye inotonhora yekukotama bvunzo ine gb244-97.
(2) Gb5310-95 machubhu esimbi asina musono epamusoro-soro boilers. Tensile test, hydraulic test uye flattening test yakafanana neiyo inotsanangurwa mu gb3087-82; Impact bvunzo zvinoenderana negb229-94, flaring bvunzo zvinoenderana neGB / t242-97 uye saizi yezviyo bvunzo zvinoenderana neYb / t5148-93; Microstructure inspection ichave inoenderana negb13298-91, decarburized layer inspection ichaenderana negb224-87, uye ultrasonic inspection ichaenderana neGB / t5777-96.
(3) Kutariswa kwekuita kwemuviri uye ma indexes emachubhu ebhailer anotengeswa kunze kwenyika anozoitwa zvinoenderana neakakodzera zviyero zvakatsanangurwa muchibvumirano (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 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 Kupisa kwesevhisi kwepaipi yepamusoro-yesimbi isina simbi iri pasi pe450 ℃, uye pombi yepamba inonyanya kugadzirwa neNo. 10 uye No.
② High pressure seamless simbi pombi inowanzove mukupisa kwepamusoro uye kudzvinyirira kwakanyanya. 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.
