Izici Eziyinhloko Zamashubhu Ohlobo 2 e-ASTM A335 P91
Uhlobo lwe-ASTM A335 P91 2 luyinsimbi ye-chrome-moly alloy eyaziwa ngamandla ayo angavamile, ukumelana nokushisa, kanye namandla okuhambahamba. Luhlukaniswa njengensimbi ye-creep strength-enhanced ferritic (CSEF), okwenza ifaneleke kakhulu ekusetshenzisweni kokushisa okuphezulu kanye nokucindezela okuphezulu. Izinto zidlula enkambisweni ethile yokwelashwa kokushisa:

Ukushisa ku-1050 °C.

Ukupholisa umoya kufikela ku-200°C.

Ukushisa ku-760 °C.

Le nqubo ithuthukisa amandla ayo okukhukhuleka nokuqina, okwenza kube ukukhetha okuhle kakhulu ezindaweni ezidinga kakhulu.

Ukwakheka kanye nezinzuzo zamashubhu ensimbi e-ASTM A335 P91
I-Chromium (9%): Ithuthukisa amandla okushisa aphezulu, ukumelana nokushiswa kwe-oxidation, kanye nezakhiwo zemishini.

I-Molybdenum (1%): Ithuthukisa ukunwebeka, ukumelana nokuguguleka, kanye namandla okuhamba ngokushisa okuphezulu.

I-Vanadium ne-Columbium/Niobium: Ithuthukisa amandla okuhamba kancane kanye nokumelana nokukhathala kokushisa.

Izinzuzo zamashubhu ensimbi e-ASTM A335 P91
Ubukhulu bodonga obuncishisiwe: Kuvumela izingxenye ezilula, isikhathi esincishisiwe sokushisela, kanye nensimbi encane yokugcwalisa.

Impilo yokukhathala okuphezulu kokushisa: Kufika izikhathi eziyi-10 kangcono kunezandulelayo njenge-T22 noma i-P22.

Ukwanda kwamazinga okushisa okusebenza: Kuthuthukisa ukusebenza kahle kwezicelo ezisebenzisa amazinga okushisa aphezulu.

Ukusetshenziswa kwama-ASTM A335 P91 Steel Tubes
I-P91 isetshenziswa kabanzi ezimbonini ezidinga izinto ezikwazi ukumelana namazinga okushisa aphezulu kanye nokucindezeleka. Izicelo ezivamile zifaka:

Ukukhiqizwa kukagesi: Ama-boiler, imigqa yokushisa kabusha, kanye nezitshalo zomjikelezo ohlanganisiwe.

Izitshalo ze-Petrochemical: Izifudumezi, imishini yokucubungula igesi, kanye nezinsizakalo zensimu kawoyela.

Izinhlelo zamapayipi ezishisa kakhulu: Zilungele imisebenzi yokugoba, yokufulela, kanye neyokushisela.

Ukwakheka Kwamakhemikhali Kwamashubhu Ensimbi e-ASTM A335 P91
Ukwakheka kwamakhemikhali kwe-P91 kuqinisekisa ukusebenza kwayo okuphezulu:

Ikhabhoni: 0.08% – 0.12%

I-Manganese: 0.30% – 0.60%

I-Chromium: 8.00% – 9.50%

I-Molybdenum: 0.85% – 1.05%

I-Vanadium: 0.18% – 0.25%

I-nitrogen: 0.030% – 0.070%

Ezinye izakhi: i-nickel, i-aluminium, i-columbium, i-titanium, ne-zirconium ngamanani alawulwayo.

Izakhiwo Zemishini
Amandla Okudonsa: Okungenani i-85,000 PSI (585 MPa).

Amandla Okukhiqiza: Okungenani i-60,000 PSI (415 MPa).

Amashubhu Ensimbi e-ASTM A335 P91 Ukushisela Nokushisa
Ukushisela i-P91 kudinga ukunamathela ngokuqinile ezinqubweni zokulondoloza izakhiwo zayo:

Ukushisa: Kubalulekile ukuvimbela ukuqhekeka okubangelwa yi-hydrogen.

Ukulawulwa kokushisa phakathi kwama-pass: Kugcinwa kusetshenziswa izinhlelo zokushisa zesimanje zokungenisa.

Ukwelashwa kokushisa ngemva kokushiswa (PWHT): Kubalulekile ukufeza isakhiwo esincane esifiselekayo nokugwema ukwehluleka.

Ama-electrode okushisela: Kumelwe afane nokwakheka kwezinto eziyinhloko.

Kungani Kufanele Ukhethe Amashubhu Ensimbi E-Womic Steel ASTM A335 P91?
Isitokwe esikhulu: Izinto ze-P91 ezisezingeni eliphezulu ezifanela zonke izidingo zakho.

Ubuchwepheshe: Ithimba elinolwazi lokukuqondisa ekukhetheni izinto kanye nokusetshenziswa kwazo.

Ukuzibophezela ekhwalithini: Izinto ezingcono kakhulu ezivela kubakhiqizi abagunyaziwe kuphela.

Ukuze uthole zonke izidingo zakho ze-ASTM A335 P91 Type 2, xhumana ne-Womic Steel namuhla. Ithimba labo likulungele ukukunikeza izixazululo ezidlula lokho okulindelwe futhi lilethe izinto ezisezingeni eliphezulu zamaphrojekthi akho.
