Impimbano Duplex A182 F60 Irembo

Irembo ryibyuma byahimbwe bivuga valve ifite irembo ryimuka rihagaritse kumurongo wo hagati. Irembo ry'ibyuma by'impimbano rikoreshwa cyane cyane mu guca mu miyoboro. Irembo ry'ibyuma byahimbwe ni valve ikoreshwa cyane, kandi muri rusange ikoreshwa mugukata ibikoresho bifite umurambararo wa DN ≤ 50. Ibyuma byinjiriro byibyuma nibisanzwe.

Duplex ibyuma bitagira umuyonga nicyuma kitagira umwanda aho kimwe cya kabiri cyicyiciro cya ferrite nigice cyicyiciro cya austenite kiboneka muburyo bukomeye bwo kuzimya, hamwe nibice byibuze 30%. Duplex ibyuma bidafite ibyuma bikozwe mukwongera Cr cyangwa kongeramo ibindi bintu bya ferrite hashingiwe kuri 18-8 austenitike idafite ibyuma. Ntabwo ifite gusa ibyerekezo bibiri bya austenite na ferrite, ahubwo ikiza Ni alloy. Bitewe nibiranga ibyiciro bibiri byububiko bwa duplex idafite ibyuma, mugucunga neza imiterere yimiti hamwe nuburyo bwo gutunganya ubushyuhe, ibyuma bya duplex bitagira umuyonga birashobora guhuza ibyiza byibyuma bya ferritic hamwe nicyuma cya austenitis. Kubaho kwa austenite muri duplex ibyuma bidafite ibyuma bigabanya ubukana bwa Cr ferrite nuburyo bwo gukura kwa kirisiti, mugihe bikomeje gukomera no gusudira; Kubaho kwa ferrite byongera imbaraga zumusaruro, kurwanya kwangirika kwingirangingo, no kurwanya chloride stress ya austenite.
