GB/T9948Ipayipi lensimbi elingenamthungo lokuqhekeka kwephethiloli liyipayipi elingenamthungo elifanele amapayipi esithando, ama-heat exchanger kanye namapayipi ezindaweni zokuhlanza i-petroleum. Insimbi yesakhiwo sekhabhoni esezingeni eliphezulu, insimbi yesakhiwo se-alloy kanye nensimbi engagqwali amapayipi aqinile angenamthungo asetshenziswa ukukhiqiza amapayipi e-steam boiler anomfutho ophezulu nangaphezulu. Lawa mapayipi e-boiler asebenza ngaphansi kokushisa okuphezulu kanye nengcindezi, futhi amapayipi avuleka entuthwini yokushisa okuphezulu. Ukubola kanye nokugqwala kuzokwenzeka futhi ngaphansi kwesenzo segesi kanye nomhwamuko wamanzi. Ngakho-ke, amapayipi ensimbi ayadingeka ukuthi abe namandla ahlala isikhathi eside, ukumelana okuphezulu kokubola, kanye nokuzinza okuhle kokuhlela. Ngaphezu kokuqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, amapayipi e-boiler anomfutho ophezulu kumele futhi enze ukuhlolwa komfutho we-hydraulic ngamunye ngamunye, okuhlanganisa nokuhlolwa kokunwetshwa kanye nokuthamba. Amapayipi angenamthungo anomfutho ophezulu alethwa esimweni sokuphathwa kokushisa.
Izindlela zokukhiqiza kanye nokukhiqiza amapayipi okuqhekeka kwephethiloli:

① Ngokuvamile, izinga lokushisa lenkonzo yamapayipi ensimbi angenamthungo lingaphansi kuka-450°C. Amapayipi asekhaya enziwe kakhulu ngeNombolo 10, Nombolo 20,12CrMo, 15CrMo, 12CrlMo, 12CrlMoV, 12Cr5MoI, 12Cr9MoI, amapayipi aguqiswa ngokushisa noma amapayipi adonswa ngokubandayo.

② Amapayipi ensimbi angenamthungo ajwayelekile e-GB9948 avame ukuchayeka ezimweni zokushisa okuphezulu kanye nokucindezela okuphezulu uma esetshenziswa. Amapayipi azokhipha umoya futhi agqwale ngaphansi kwesenzo segesi yokushisa okuphezulu kanye nomhwamuko wamanzi. Amapayipi ensimbi ayadingeka ukuthi abe namandla ahlala isikhathi eside, ukumelana okuphezulu nokugqwala, kanye nokuqina okuhle kwesakhiwo.

sebenzisa:

① Ngokuvamile, amapayipi ensimbi angenamthungo asetshenziswa kakhulu ukwenza amapayipi odonga lwamanzi, amapayipi amanzi abilayo, amapayipi omusi ashisiwe kakhulu, amapayipi omusi ashisiwe kakhulu amabhoyila esitimela, amapayipi amakhulu namancane omusi kanye namapayipi ezitini ezigobile, njll.

Ipayipi lensimbi elingenamthungo le-②GB9948 lisetshenziswa kakhulu ukukhiqiza amashubhu e-superheater, amashubhu okuvuselela, amashubhu okuqondisa umoya, amashubhu amakhulu omusi, njll. kuma-boiler anomfutho ophezulu kanye nomfutho ophezulu kakhulu.

Amapayipi ensimbi angenamthungo ajwayelekile e-GB9948 ahlukaniswe ngamapayipi e-boiler ajwayelekile kanye namapayipi e-boiler anomfutho ophezulu ngokuya ngokusebenza kwawo okushisa okuphezulu. Kungakhathaliseki ukuthi amapayipi e-boiler ajwayelekile noma amapayipi e-boiler anomfutho ophezulu, angahlukaniswa ngamapayipi ensimbi ahlukahlukene ngokuya ngezidingo zawo zokusetshenziswa ezahlukene.
Ipayipi lensimbi elingenamthungo le-GB/T9948, ububanzi bangaphandle bungu-10 ~ 426mm, ubukhulu bodonga bungu-1.5 ~ 26mm. Ububanzi bangaphandle kanye nobukhulu bodonga lwamapayipi omusi ashisayo kakhulu, amapayipi amakhulu omusi, amapayipi amancane omusi kanye namapayipi ezitini ezigobile asetshenziswa kuma-boiler e-locomotive kuchazwe ngenye indlela.

Ikhwalithi yokubukeka: Akukho mifantu, imigoqo, imiqulu, ama-scabs, ukuhlukanisa kanye nemigqa yezinwele evunyelwe ezindaweni zangaphakathi nezangaphandle zamapayipi ensimbi. Lawa maphutha kufanele asuswe ngokuphelele. Ukujula kokuhlanza akufanele kudlule ukuphambuka okungekuhle kobukhulu bodonga obujwayelekile, futhi ubukhulu bodonga bangempela endaweni yokuhlanza akufanele bube ngaphansi kobukhulu bodonga obuvunyelwe okungenani.
