Izici ezibalulekile ze-ASTM A335 P91 Type 2 Tubes
I-ASTM A335 P91 Type 2 iyinsimbi ye-alloy ye-Chrome-moly eyaziwa ngamandla aso ahlukile, ukumelana nokushisa, kanye namandla okuqina. Ihlukaniswe njengensimbi evuthayo ye-Ferritic Izinto ezibonakalayo zenzeke inqubo ethile yokwelashwa okushisa:

Ukwehlukanisa ngo-1050 ° C.

Ukupholisa umoya kuya ku-200 ° C.

Ukufutheka ngo-760 ° C.

Le nqubo ithuthukisa amandla ayo nokuqina, okwenza kube ukukhetha okuphakeme kwezindawo ezifunwayo.

Ukwakheka nezinzuzo ze-ASTM A335 P91 Steel Amashubhu
I-Chromium (9%): Ithuthukisa amandla aphezulu okushisa, ukumelana oxidation, kanye nezakhiwo zemishini.

I-Molybdenum (1%): Ithuthukisa ukuqina, ukugqoka ukumelana, namandla aphezulu okushisa aphezulu.

UVanadium neColumbium / Niobium: Eqhubeka nokukhulisa amandla ama-creep kanye nokumelana nokukhathala okushisayo.

Izinzuzo ze-ASTM A335 P91 Steel Tubes
Ukuncipha kodonga okuncishisiwe

Impilo ephakeme yokukhathala ephakeme: kufika izikhathi eziyi-10 kangcono kunabaphambi kwangaphambili njenge-T22 noma i-P22.

Amazinga okushisa asebenzayo: athuthukisa ukusebenza kahle kuzicelo ezishisa kakhulu.

Izicelo ze-ASTM A335 P91 TUBES
I-P91 isetshenziswa kabanzi ezimbonini ezidinga izinto ezikwazi ukubekezelela ukukala okuthe xaxa kanye nezingcindezi. Izicelo ezijwayelekile zifaka:

Isizukulwane samandla: ama-boilers, imigqa yokuvuselela kabusha, nezitshalo zomjikelezo ezihlanganisiwe.

Izitshalo ze-petrochemical: ama-heater, imishini yokucubungula igesi, kanye nezinsizakalo ze-oilfield.

Amasistimu wokushisa amapayipi aphezulu: alungele ukugoba, ukugcwala kanye nokusebenza kwe-welding.

Ukwakheka kwamakhemikhali kwamashubhu wensimbi a335 p91
Ukwakheka kwamakhemikhali kwe-P91 kuqinisekisa ukusebenza kwalo okuphezulu:

I-Carbon: 0.08% - 0.12%

I-Manganese: 0.30% - 0.60%

I-Chromium: 8.00% - 9.50%

Molybdenum: 0.85% - 1.05%

I-Agadium: 0.18% - 0.25%

I-Nitrogen: 0.030% - 0.070%

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

Izakhiwo zemishini
Amandla we-Tensile: Ubuncane be-85,000 PSI (585 MPA).

Ukukhiqiza amandla: ubuncane obungu-60,000 PSI (415 MPA).

I-Welding and Helding Treatment Treatment ASTM A335 P91 STEMS TUBES
I-Welding P91 idinga ukubambelela okuqinile ezinhlelweni zokugcina izakhiwo zayo:

Ukucaca: kubalulekile ukuvikela ukuqhekeka okubangelwa yi-hydrogen.

Ukulawulwa kokushisa okuphakelayo: Kugcinwe kusetshenziswa izinhlelo zesimanje zokufudumeza.

Ukwelashwa okushisa ngemuva kokushisa (i-PWHT): Kugxeka ukufeza ukufezekisa i-mismscucture efiselekayo futhi uvikele ukwehluleka.

I-Welding electrodes: Kufanele ihambisane nokwakheka komzali.

Kungani Khetha Amashubhu wensimbi we-ASTM A335 P91?
Ukusungula okubanzi: Izinto ezisezingeni eliphakeme ze-P91 zazo zonke izidingo zakho.

Isazi: Ithimba elinolwazi ukukuqondisa ngokukhethwa kwezinto ezibonakalayo kanye nesicelo.

Ukuzibophezela kwikhwalithi: kuphela izinto ezinhle kakhulu ezivela kubakhiqizi abavunyiwe.

Kuzo zonke izidingo zakho ze-ASTM A335 P91 Thayipha 2, thintana nensimbi ye-Wometic namuhla. Iqembu labo lilungele ukuhlinzeka ngezixazululo ezidlula okulindelwe futhi zilethe izinto ezisezingeni eliphakeme kakhulu zamaphrojekthi akho.
