I-China ASTM A53 Gr.B Ipayipi Lensimbi Eligingqelwe Ikhabhoni Elingenamthungo
Incazelo emfushane:
Le Pipe Yensimbi Yengxubevange ene-12cr1MOV Material iyipayipi lensimbi elingenamthungo elingasetshenziswa ekufakweni kwe-petroleum, amakhemikhali, amandla kagesi namabhayela.Inezici zokumelana nokubanda, ukumelana nokushisa nokumelana nokugqwala.I-12Cr1MoV iwuhlobo lwepayipi lengxubevange.Inhloso eyinhloko ukwenza izingxenye zensimbi zesakhiwo kubhayela.
Ngokuhambisana nomgomo "wekhwalithi, isevisi, ukusebenza kahle nokukhula", sizuze ukwethenjwa nezindumiso ezivela kumakhasimende asekhaya nawamazwe ngamazwe e-China ASTM A53 Gr.B Ipayipi Lensimbi Eligingqelwe Ikhabhoni Elingenamthungo, Ngemibuzo eyengeziwe noma uma ungase ube nanoma yimuphi umbuzo mayelana nezimpahla zethu, qiniseka ukuthi ungangabazi ukusishayela ucingo.
Ngokuhambisana nomgomo “wekhwalithi, isevisi, ukusebenza kahle nokukhula”, sithole ukwethenjwa nokutuswa kumakhasimende asekhaya nawamazwe ngamazweChina Steel Pipe kanye Carbon Pipe, Siya ngokuya sinweba isabelo sethu semakethe yamazwe ngamazwe ngokusekelwe ezintweni zekhwalithi, isevisi enhle kakhulu, intengo enengqondo kanye nokulethwa ngesikhathi.Sicela usithinte nganoma yisiphi isikhathi ukuze uthole ulwazi olwengeziwe.
Izinga lokushisa lesevisi lingu-580 ℃, futhi ipuleti lensimbi liyadingeka ukuze libe namandla okumelana nezinga lokushisa eliphezulu.Ipuleti lensimbi lilethwa esimweni esijwayelekile nesithambile.Ipayipi lengxubevange le-12Cr1MoVG lisuselwa kunsimbi yesakhiwo sekhabhoni yekhwalithi ephezulu, futhi i-elementi yealloy eyodwa noma ezimbalwa zengezwa ngokufanelekile ukuze kuthuthukiswe izakhiwo zemishini, ukuqina kanye nokuqina kwensimbi.Imikhiqizo eyenziwe ngensimbi enjalo ngokuvamile idinga ukwelashwa kokushisa (i-normalizing noma ukucisha kanye nokushisa);Izingxenye kanye nezingxenye ezenziwe ngazo ngokuvamile zidinga ukucinywa kanye nokushisa noma ukwelashwa kwamakhemikhali okungaphezulu (i-carburizing, i-nitriding, njll.), ukucisha ingaphezulu noma ukucishwa kwe-high-frequency ngaphambi kokusetshenziswa.Ngakho-ke, ngokuya ngenhlanganisela yamakhemikhali ahlukene (ikakhulukazi okuqukethwe kwekhabhoni), izinqubo zokwelapha ukushisa kanye nezicelo, izinsimbi ezinjalo zingahlukaniswa cishe zibe izinsimbi ezishisiwe, ezicishiwe nezinomoya kanye ne-nitrided.
Okokuqala, ingagaywa kabusha ngo-100%, yonge amandla kanye nokuvikelwa kwemvelo.
Okwesibili, ine-plasticity ephakeme kakhulu futhi ingasetshenziselwa ukukhiqizwa nokucubungula kwesibili.
Okwesithathu, ine-conductivity enhle yokushisa kanye nekhono lokushisa eliphezulu lokukhasa.
Okwesine, inokumelana kahle ne-oxidation kanye nokumelana nokugqwala.
Okwesihlanu, inokusebenza okuhle okubandayo nokushisayo.
I-12Cr1MoVG iwuhlobo lwepayipi yensimbi ye-chromium molybdenum ingxubevange, lapho izingxenye eziyinhloko zamakhemikhali ziyi-carbon 0.08-0.15, i-silicon 0.17-0.37, i-manganese 0.40-0.70, i-phosphorus engekho ngaphezu kwe-0.035, isulfure engekho ngaphezu kwe-10,0. i-molybdenum 0.25-0.35, i-alum 0.15-0.30, njll.
Okokuqala, isetshenziselwa ikakhulukazi ukwenza amashubhu e-alloy ane-high-pressure alloy ukushisa izindawo zama-boilers wamanzi anengcindezi ephezulu nangaphezulu.
Okwesibili, isetshenziswa kakhulu kuma-superheaters, izihloko kanye namapayipi amakhulu omusi we-high-pressure yasekhaya, i-ultra-high kanye nama-boilers wesiteshi samandla angaphansi.
Okwesithathu, amapayipi amakhulu amakhulu asetshenziswa kakhulu njengamaheda kanye namaConduits aMain Steam anemingcele engaphansi kuka-565 ℃.
Okokuqala, ukugeleza kwenqubo yokugoqa okushisayo (ipayipi lensimbi engenamthungo):
I-tube billet eyindilinga → ukushisisa → ukubhoboza → ukugingqeka kwamaroli amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula amapayipi → ukusika (noma ukunciphisa) → ukupholisa → i-billet → ukuqondisa → ukuhlolwa kwe-hydrostatic (noma ukutholwa kwamaphutha) → ukumaka → indawo yokugcina impahla.
Okwesibili, ukugeleza kwenqubo yepayipi yensimbi engenamthungo (egoqayo) ebandayo:
I-tube billet eyindilinga → ukushisisa → ukubhoboza → isihloko → ukudonsa → ukukhetha → ukugcotshwa kukawoyela (i-copper plating) → umdwebo obandayo wokudlula okuningi (ukugoqa okubandayo) → ishubhu le-billet → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa kwe-hydrostatic (noma ukutholwa kwamaphutha) → ukumaka → indawo yokugcina impahla.

Ngokuhambisana nomgomo "wekhwalithi, isevisi, ukusebenza kahle nokukhula", sizuze ukwethenjwa nezindumiso ezivela kumakhasimende asekhaya nawamazwe ngamazwe e-China STM A53 Gr.B Ipayipi Lensimbi Eligingqelwe Ikhabhoni Elingenamthungo, Ngemibuzo eyengeziwe noma uma ungase ube nanoma yimuphi umbuzo mayelana nezimpahla zethu, qiniseka ukuthi ungangabazi ukusishayela ucingo.
China Steel Pipe kanye Carbon Pipe, Siya ngokuya sinweba isabelo sethu semakethe yamazwe ngamazwe ngokusekelwe ezintweni zekhwalithi, isevisi enhle kakhulu, intengo enengqondo kanye nokulethwa ngesikhathi.Sicela usithinte nganoma yisiphi isikhathi ukuze uthole ulwazi olwengeziwe.
