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.

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