Mawonekedwe a Asthem A335 P91 Mtundu wa 2 machubu
Astme A335 P91 Mtundu 2 ndi chithokomiro-moly alloy soya wodziwika chifukwa cha mphamvu zake zapadera, kupikisana ndi kutentha, komanso nyonga. Imadziwika kuti ndi mphamvu yokwezeka yamphamvu (CSSEF) chitsulo, ndikupanga kukhala yabwino kutentha kwambiri komanso kugwiritsa ntchito kwambiri ntchito zapamwamba. Zinthu zomwe zimaphatikizira njira inayake yochitira kutentha:

Kusintha kwa 1050 ° C.

Mpweya wozizira mpaka 200 ° C.

Kusamala pa 760 ° C.

Izi zimawonjezera mphamvu zake zogulira ndi kulimba, zimapangitsa kuti zikhale zabwino kwambiri zofunika.

Kuphatikizika ndi mapindu a Asthem A335 P91 Chitsulo Chitsulo
Chromium (9%): Zimakulitsa mphamvu zambiri-zotentha kwambiri, ma oxidation kukana, ndi makina.

Molybdenum (1%): Amasintha bwino, kuvala kukana, komanso kutentha kwambiri.

KANDAIL NDI Columbium / Niobium: Kuchulukitsa kwambiri kutopa.

Ubwino wa Astm A335 P91 Chitsulo Chitsulo
Kuchepetsa khoma makulidwe: amalola kuti azikhala ndi zigawo zopepuka, kuchepetsa nthawi, komanso zitsulo zochepa zofananira.

Moyo wambiri wambiri: mpaka nthawi 10 kuposa omwe adatsogolera ngati T22 kapena P22.

Kuchulukitsa kutentha kwa ntchito: kumathandizanso kugwiritsa ntchito kutentha kwambiri.

Mapulogalamu a Asthem A335 P91 SHEEL SUT
P91 imagwiritsidwa ntchito kwambiri m'makampani omwe amafunikira zinthu zomwe zimatha kutentha kwambiri komanso zovuta. Ntchito Zodziwika Pafupi ndi:

Mbadwo Wamphamvu: Akailer, mizere yadziko, ndikuphatikiza zomera za kuzungulira.

Zomera za Petrochemical: Heaters, zida zamagesi, ndi ntchito zamafuta.

Makina otentha kwambiri: oyenera kugwada, akuyenda, ndi kuwotcherera.

Kupanga kwam'madzi kwa Asthem A335 P91 Chitsulo Chitsulo
Kupanga kwamankhwala kwa P91 kumatsimikizira ntchito yake yayikulu:

Kaboni: 0.08% - 0.12%

Manganese: 0.30% - 0.60%

Chromium: 8.00% - 9.50%

Molybdenum: 0.85% - 1.05%

Vadium: 0.18% - 0.25%

Nayitrogeni: 0.030% - 0.070%

Zina: Nickel, aluminium, columbium, titanium, ndi zirconium yolamulidwa.

Makina
Mphamvu yakukhala: yochepera 85,000 (585 MPA).

ZOTHANDIZA: Zochepera 60,000 ppi (415 MPA).

Kutentha ndi kutentha mankhwala a Astam A335 P91 Zitsulo Zitsulo
Kutentha P91 kumafuna kutsatira njira kuti musunge zinthu zake:

Kuthetsa: ndikofunikira kuti mupewe kuwonongeka kwa haidrojeni.

Kuwongolera kutentha kwapakati: kusungidwa pogwiritsa ntchito njira zamakono zothandizira.

Chithandizo cha post-weld kutentha (pwht): Chochititsa chidwi kuti akwaniritse micrestcultuctuctunce solction ndikupewa zolephera.

Ma elekitirodi owotchera: iyenera kufanana ndi zomwe makolo akupanga.

Chifukwa chiyani kusankha wachitsulo kwamimba AS335 P91 Chitsulo chachitsulo?
Zida zazikulu: Zipangizo zapamwamba za P91 za zosowa zanu zonse.

Ukatswiri: Gulu lodziwa bwino ntchito kuti likuwongolereni pogwiritsa ntchito kusankha ndi kugwiritsa ntchito.

Kudzipereka ku mtundu: zokhazo zomwe zimakhala ndi zovomerezeka.

Kwa Astm onse a Astm A335 P91 Mtundu wa 2 zofunikira, zokhudzana ndi zingwe zamasamba lero. Gulu lawo lakonzeka kupereka mayankho omwe amapitilira zomwe mukuyembekezera komanso kupereka zida zapamwamba kwambiri pantchito zanu.
