Seamless karfe bututu ga man fetur cracking
Matsayi: GB9948
Amfani：
Seamless karfe bututu da aka yi amfani da shi ga man fetur, refineries, zafi musayar bututu da bututu.
Main samar da karfe bututu iri:
10, 20, 15CrMo, 1Cr2Mo, 1Cr5Mo da dai sauransu
Yanayin Bayarwa:
Yanayin Bayarwa:
10, 20 <Hot madaidaiciya bututu karshen madaidaiciya, sanyi janye bututu m wuta>
15CrMo <Hot madaidaiciya bututu karshen madaidaiciya + annealing, sanyi cire bututu m wuta + annealing>
1Cr2Mo <Hot madaidaiciya bututu karshen madaidaiciya + annealing, sanyi janye bututu m wuta + annealing>
1Cr5Mo <Tsara>
Weight lissafi formula: PU carbon bututu: (waje diamita - bango kauri) X bango kauri X0.02466 = KG / M
