Momwe mungasankhire zida za WCB/LCB/LCC/WC6/WC za vavu?

W amatanthauza kulemba, kuponya;

C-CARBON zitsulo zitsulo za carbon, A, b, ndi C zimasonyeza mphamvu yamtundu wa chitsulo kuyambira pansi mpaka pamwamba.

WCA, WCB, WCC imayimira chitsulo cha carbon, chomwe chili ndi ntchito yabwino yowotcherera komanso mphamvu zamakina.ABC imayimira mphamvu yamphamvu, yomwe imagwiritsidwa ntchito kwambiri ndi WCB.Chitoliro chogwirizana ndi WCB chiyenera kukhala A106B, ndipo zopangira zofananira ndi A105.Oyenera mavavu pansi ochiritsira kutentha ndi kupanikizika.

WC6 ndi kuponyedwa kwa aloyi zitsulo.Ili ndi kukana kwambiri kutentha kwambiri komanso antioxidant katundu ndipo ndi yoyenera mavavu pansi pa kutentha kwambiri komanso kupanikizika kwambiri.

Mapaipi ofanana ndi pafupifupi A355 P11, ndipo gawo lopangira ndi A182 F11;

Komanso, pali WC9, mkulu-kutentha aloyi zitsulo lolingana za A355 P22, ndi forging ayenera zikugwirizana A182 F22.

WC welded casting ali ndi mphamvu zambiri komanso kuuma.Oyenera ntchito wamba mafakitale.

LCB/LCC (ASTM A352) Chitsulo cha carbon chotsika chimakhala ndi kulimba kochepa komanso kukana dzimbiri.Ndizoyenera kugwiritsa ntchito kutentha kwapang'onopang'ono -otsika kwambiri, monga LPG gasi wachilengedwe (LNG).

Zfa Mavavu amapanga mavavu agulugufe wamba a WCB kwa makasitomala padziko lonse lapansi omwe ali ndi kutentha kofanana, komanso titha kupanga ma valve agulugufe a LCC kwa Makasitomala ochokera Kumpoto kwa Europe monga Russia, Finland etc.

pamwamba ndi WCBChina wafer butterfly valvendi LCCChina lug butterflyvalavu.

Zopangira zitsulo za kaboni ndi zida zopukutira zomwe zimagwiritsidwa ntchito m'mavavu

Low -kutentha kuponyedwa zitsulo zinthu makalasi ndi kutentha ntchito

Zida za ASTM zopangira ndi kuyerekezera matebulo omwe amagwiritsidwa ntchito kwambiri m'mavavu (ASME B16.5)

Zindikirani: 1) ma valve opangidwa ndi thupi lopangidwa ndi thupi lolimba, losavuta kukhala ndi zilema, kukula kwake sikungagwirizane ndi zofooka za nkhungu, ntchito yodalirika yothamanga, yomwe imagwiritsidwa ntchito kwambiri kupanikizika kwambiri, mpweya wa okosijeni, m'mimba mwake pang'ono kapena ma valve ena ang'onoang'ono. kupanga kwapamwamba kwambiri, kuthamanga kwambiri kapena kutsika kapena kutsika kwapadera kapena zofalitsa zapadera pansi pa chisankho cha kufota;kuponyera nthawi zambiri kumangogwiritsidwa ntchito papakatikati komanso kutsika, ndipo kumagwiritsidwa ntchito popanga mavavu okhazikika pakupanga misa.

(2) Zinthu A351 CF3M ndi A182 F316L kusiyana: mfundo ziwiri zimagwirizana ndi zinthu 316 zitsulo zosapanga dzimbiri.CF3M limasonyeza kuti kuponyera, ambiri ntchito ngati zipangizo valavu.Khodi yachitsulo yofananira ndi A182 F316L.ASTM A216 WCB ikuponya, ndipo zojambula zake ndi A105;SS304 castings ndi A351-CF8, ndipo forgings ndi A182-F304.
