Ob Tsev Neeg Khoom
Cov raj tooj liab tau muab faib ua cov raj tooj liab liab thiab tooj dag los ntawm cov khoom siv. Cov raj tooj liab liab yog tsim los ntawm cov qib xws li T2, T3, T4, thiab TUP, nrog cov ntsiab lus tooj liab siab ntau dua 99.7 feem pua. Brass tubes yog tsim los ntawm qib xws li H62 thiab H68, uas yog alloys ntawm zinc thiab tooj liab. Piv txwv li, H62 tooj dag raj muaj cov khoom siv ntawm 60.5 mus rau 63.5 feem pua tooj liab, txog 39.6 feem pua zinc, thiab lwm yam impurities hauv qab 0.5 feem pua.
Kev tsim khoom
Cov txheej txheem tsim ntawm cov raj tooj liab tau muab faib ua cov duab kos thiab extrusion. Sab nraud txoj kab uas hla ntawm cov raj tooj liab yog los ntawm 3 mus rau 200 hli, thiab sab nraud txoj kab uas hla ntawm extruded tooj liab raj yog li ntawm 32 mus rau 280 hli nrog phab ntsa thickness ntawm 1.5 mus rau 5 hli. Qhov tshwj xeeb ntawm cov phaj tooj liab coiled tooj liab raj yog 155 mus rau 505 hli txheej kab, thiab cov txheej txheem muab khoom yog ib qhov ntev thiab coils.
Ua haujlwm kub thiab kev siv
Qhov ntsuas kub ua haujlwm ntawm cov raj tooj liab yog qis dua 250 ° C, thiab lawv feem ntau yog siv rau hauv cov kav dej, cov kav dej sib txuas nrog cov kav dej, thiab cov pa sib cais ntawm cov pa oxygen pipelines. Kev sib xyaw ua ke ntawm kev tiv thaiv corrosion, thermal conductivity, thiab siab muaj peev xwm ua rau lawv haum rau kev thauj cov dej hauv cov tshuab ua haujlwm.
Yog vim li cas tooj dag Tubes
Cov raj tooj dag xws li H62 thiab H68 muab lub zog ntau dua thiab tawv dua li cov raj tooj liab ntshiab thaum khaws cov khoom zoo corrosion thiab formability. H68 tooj dag muaj txog 68 feem pua tooj liab thiab yog softer thiab ntau ductile, suiting sib sib zog nqus nqus thiab txias forming, thaum H62 sib npaug zog thiab formability rau general engineering siv.
Kev Taw Qhia Xaiv
Xaiv cov raj tooj liab liab uas yuav tsum muaj hluav taws xob lossis thermal conductivity thiab purity siab tshaj plaws, thiab cov raj tooj liab qhov twg lub zog, hardness, los yog nqi -effectiveness tseem ceeb. Qhia txog qib, sab nraud, phab ntsa thickness, thiab daim ntawv muab khoom, thiab paub meej tias yuav tsum muaj cov qauv rau daim ntawv thov.
