Ikhwalithi ephezulu ye-ASTM A335 P91 Umkhiqizi wamapayipi ongenamthungo we-Seel e-China
Uhlolojikelele
Ukuthuthuka kwethu kuncike emishinini ethuthukisiwe, amathalente amahle kakhulu kanye namandla obuchwepheshe aqiniswa ngokuqhubekayo epayipini lethu lensimbi lekhwalithi ephezulu, Sizoqhubeka silwela ukukhulisa inkampani yethu futhi sinikeze imikhiqizo yekhwalithi efanelekile enamanani anamandla.Noma yimuphi umbuzo noma ukuphawula kwaziswa kakhulu.Khumbula ukusibamba ngokukhululeka.Inkampani yethu isebenza ngesimiso sokusebenza "sokusekelwe kobuqotho, ukubambisana okudalwe, okuthambekele kubantu, ukubambisana okuphumelelayo".Sithemba ukuthi singaba nobudlelwano obunobungane nosomabhizinisi abavela kuwo wonke umhlaba
I-P91 ayinakho nje kuphela ukumelana ne-oxidation ephezulu kanye nokumelana nokugqwala kwezinga lokushisa eliphezulu, kodwa futhi inokuqina komthelela omuhle kanye nepulasitiki ephakeme nezinzile ehlala isikhathi eside namandla ashisayo.Uma izinga lokushisa lesevisi lingaphansi kuka-620 ℃, ukucindezeleka kwayo okuvunyelwe kungaphezu kwalokho kwe-austenitic stainless steel.Ngaphezulu kuka-550℃, idizayini enconyiwe ingcindezi icishe iphindwe kabili kuneyensimbi ye-T9 ne-2.25Cr-1Mo.Ingasetshenziswa njenge-superheater ephezulu kanye nepayipi lensimbi lokufudumeza kabusha kwe-subcritical kanye ne-supercritical boiler wall lokushisa ≤625℃, izinga lokushisa eliphakeme lesihloko nezinga lokushisa lodonga lwepayipi lesimusi ≤600℃, kanye nesishintshi sokushisa samandla enuzi kanye neshubhu yesithando somlilo weyunithi yokuqhekeka kwe-petroleum.
Isicelo
Isetshenziswa kakhulu ukwenza ipayipi le-boiler yensimbi esezingeni eliphakeme, ipayipi elishintshana ngokushisa, ipayipi elinomfutho ophezulu we-petroleum kanye nemboni yamakhemikhali.
