Womic Steel yadzikhazikitsa yokha ngati kampani yodalirika yopereka zipangizo ndi mayankho apamwamba kwa zaka 20. Podzipereka kuchita bwino kwambiri, kampaniyo imagwira ntchito m'mafakitale osiyanasiyana, kupereka mayankho okonzedwa kuti akwaniritse zosowa zinazake. Zinthu zawo, zomwe zikuphatikizapo zipangizo zapamwamba za ASTM A335 P91 Type 2, zimachokera kwa opanga ovomerezeka padziko lonse lapansi ndipo zimasinthidwa nthawi zonse kuti zikwaniritse miyezo yapamwamba kwambiri. Womic Steel imagwira ntchito yopereka zipangizo za P91 zogwiritsira ntchito mphamvu zambiri, kuphatikizapo mapaipi, zolumikizira, ma valve, ma flange, ndi zina zambiri, kuonetsetsa kuti makasitomala alandira zinthu zabwino kwambiri.

Zinthu Zofunika Kwambiri za machubu a ASTM A335 P91 Type 2
ASTM A335 P91 Mtundu 2 ndi chitsulo cha chrome-moly chodziwika ndi mphamvu zake zapadera, kukana kutentha, komanso mphamvu zake zoyenda. Chimagawidwa ngati chitsulo cha creep strength-enhanced ferritic (CSEF), zomwe zimapangitsa kuti chigwiritsidwe ntchito kutentha kwambiri komanso kuthamanga kwambiri. Zipangizozi zimadutsa mu njira yapadera yochizira kutentha:

Kukhazikika pa kutentha kwa 1050 °C.

Kuziziritsa mpweya kufika pa 200 °C.

Kutentha kwa kutentha pa 760 °C.

Njirayi imawonjezera mphamvu zake zoyenda komanso kulimba, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri m'malo ovuta.

Kapangidwe ndi Ubwino wa Machubu a Chitsulo a ASTM A335 P91
Chromium (9%): Imalimbitsa mphamvu ya kutentha kwambiri, kukana okosijeni, komanso mphamvu zamakanika.

Molybdenum (1%): Imawonjezera kusinthasintha, kukana kuwonongeka, komanso mphamvu yokwera kutentha kwambiri.

Vanadium ndi Columbium/Niobium: Zimawonjezera mphamvu ya kukwawa komanso kukana kutentha.

Ubwino wa Machubu a Chitsulo a ASTM A335 P91
Kuchepa kwa makulidwe a khoma: Kumalola kuti zinthu zikhale zopepuka, nthawi yocheperako yowotcherera, komanso chitsulo chochepa chodzaza.

Kutopa kwambiri kwa kutentha: Kuposa nthawi 10 kuposa zida zakale monga T22 kapena P22.

Kutentha kowonjezereka: Kumawonjezera magwiridwe antchito pakugwiritsa ntchito kutentha kwambiri.

Kugwiritsa ntchito machubu achitsulo a ASTM A335 P91
P91 imagwiritsidwa ntchito kwambiri m'mafakitale omwe amafunikira zipangizo zomwe zimatha kupirira kutentha kwambiri komanso kupsinjika. Ntchito zodziwika bwino ndi izi:

Kupanga magetsi: Maboiler, mawaya otenthetsera, ndi malo ochitira ma cycle ophatikizana.

Malo opangira mafuta: Zotenthetsera, zida zopangira gasi, ndi ntchito za m'munda wamafuta.

Mapaipi otentha kwambiri: Oyenera kupindika, kupotoza, ndi kuwotcherera.

Mapangidwe a Mankhwala a Machubu a Chitsulo a ASTM A335 P91
Kapangidwe ka mankhwala ka P91 kamatsimikizira kuti imagwira ntchito bwino kwambiri:

Mpweya: 0.08% - 0.12%

Manganese: 0.30% - 0.60%

Chromium: 8.00% - 9.50%

Molybdenum: 0.85% - 1.05%

Vanadium: 0.18% - 0.25%

Nayitrogeni: 0.030% - 0.070%

Zinthu zina: nikeli, aluminiyamu, columbium, titaniyamu, ndi zirconium mu kuchuluka koyenera.

Katundu wa Makina
Mphamvu Yokoka: Osachepera 85,000 PSI (585 MPa).

Mphamvu Yotulutsa: Osachepera 60,000 PSI (415 MPa).

Kuwotcherera ndi Kutentha Machubu a Chitsulo a ASTM A335 P91
Kuwotcherera P91 kumafuna kutsatira kwambiri njira zosungira katundu wake:

Kutentha: Chofunika kwambiri kuti mupewe kusweka kwa haidrojeni.

Kuwongolera kutentha pakati pa ma pass: Kumasamalidwa pogwiritsa ntchito makina amakono otenthetsera omwe amapangidwa ndi induction.

Chithandizo cha kutentha pambuyo pa weld (PWHT): Chofunika kwambiri kuti tikwaniritse kapangidwe kake kakang'ono komanso kupewa kulephera.

Ma electrode olumikizirana: Ayenera kufanana ndi kapangidwe ka zinthu zazikulu.

N’chifukwa Chiyani Muyenera Kusankha Machubu Achitsulo a Womic Steel ASTM A335 P91?
Zinthu zambiri: Zipangizo zapamwamba za P91 zomwe zikugwirizana ndi zosowa zanu zonse.

Ukatswiri: Gulu lodziwa bwino ntchito kuti likutsogolereni posankha zinthu ndi kugwiritsa ntchito.

Kudzipereka ku khalidwe: Zipangizo zabwino kwambiri zokha kuchokera kwa opanga ovomerezeka.

Kuti mudziwe zofunikira zonse za ASTM A335 P91 Type 2, funsani Womic Steel lero. Gulu lawo lakonzeka kupereka mayankho omwe amaposa zomwe mumayembekezera komanso kupereka zipangizo zabwino kwambiri pamapulojekiti anu.
