UNS C44300 Admiralty Brass Tube PDF

ASTM B111 tooj liab yeeb nkab PDF

Inhibited Admiralty Brass tubes - ASTM B111 C44300 - muaj kev tiv thaiv corrosion siab, thiab feem ntau yog siv rau cov tubing ntawm chav condensers txias nrog tshiab, ntsev, los yog dej brackish. Lawv kuj tseem siv rau cov khoom siv hluav taws xob sib hloov hauv cov roj refineries, uas qhov corrosion ntawm sulfur compounds thiab dej tsis huv yuav hnyav heev. Rau cov txheej txheem kev lag luam, nws yog siv rau pub- cov khoom siv dej kub thiab cua sov- cov khoom sib pauv.

Cov tshuaj muaj pes tsawg leeg ntawm C44300 tin tooj dag suav nrog cov khoom xws li tooj liab, tin, npib tsib xee, hlau, txhuas, thiab manganese. Cov ntsiab lus tooj liab yog li ntawm 69.0% mus rau 71.0%, cov ntsiab lus tin ntawm 0.8% mus rau 1.3%, cov ntsiab lus npib tsib xee los ntawm 0.5%, cov ntsiab lus hlau los ntawm 0.10%, cov ntsiab lus txhuas los ntawm 0.05%, manganese cov ntsiab lus tsis zoo, cov ntsiab lus zinc yog nyob rau hauv qhov sib npaug, thiab cov ntsiab lus ntawm lwm cov ntsiab lus .0% ntawm 0.6% arse. Cov khoom no nthuav tawm cov khoom siv zoo heev, nrog lub zog tensile σb (MPa) Ntau dua lossis sib npaug rau 410 thiab elongation δ10 (%) Ntau dua lossis sib npaug rau 8, ua kom pom lub zog zoo thiab ductility.

C44300 tin tooj dag nthuav tawm qhov zoo tshaj plaws corrosion kuj, ua tsaug rau nws cov ntsiab lus arsenic. Trace arsenic inhibits dezincification corrosion, ntxiv txhim kho cov alloy qhov corrosion kuj. Yog li ntawd, C44300 tin tooj dag yog qhov tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv hluav taws xob thiab cov kav dej hauv kev sib cuag nrog cov kua corrosive. Cov kev tshawb fawb tsis ntev los no kuj tau pom tias ntxiv cov lej ntawm cov ntsiab lus xws li boron thiab npib tsib xee rau C44300 tuaj yeem txhim kho cov hlau tiv thaiv corrosion ntxiv.

C44300 tin tooj dag qhia tau zoo heev ua haujlwm txias, ua rau nws zoo tagnrho rau kev tsim cov condenser, evaporator, thiab cua kub exchanger raj. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias C44300 tin tooj dag yog qhov ua rau muaj kev ntxhov siab corrosion tawg; yog li ntawd, txias- cov hlab ua haujlwm yuav tsum tau qis-kub annealing los txo kev ntxhov siab. Tsis tas li ntawd, cov ntsiab lus impurity yuav tsum tau tswj nruj me ntsis thaum lub sij hawm kub nias kom tsis txhob cuam tshuam cov khoom siv.
