Khoom Taw qhia

Duplex steel welded raj yog ib hom tubular khoom tsim los ntawm duplex stainless hlau los ntawm txoj kev vuam. Duplex stainless hlau yog ib qho tshwj xeeb alloy uas sib txuas cov yam ntxwv ntawm austenitic thiab ferritic stainless hlau. Ib qho ntawm cov khoom tseem ceeb ntawm duplex steel welded raj yog lawv lub zog tshwj xeeb, uas tso cai rau lawv tiv taus siab thiab hnyav. Tsis tas li ntawd, cov raj no muaj kev tiv thaiv zoo heev rau corrosion, nrog rau kev tiv thaiv kev ntxhov siab corrosion cracking, ua rau lawv haum rau ntau yam nyuaj ib puag ncig.

Yuav ua li cas cov txheej txheem ntawm duplex steel welded raj txawv ntawm lwm hom steel hlab?

Kev tsim cov txheej txheem ntawm duplex steel welded raj sib txawv los ntawm lwm hom steel raj, feem ntau nyob rau hauv txoj kev vuam siv. Duplex steel welded raj feem ntau yog tsim los ntawm ob txoj kev: tsis siv neeg tungsten inert gas (TIG) vuam thiab cov txheej txheem plasma vuam tsis siv neeg. Cov txheej txheem no tso cai rau kev tswj xyuas meej ntawm cov khoom siv vuam, ua kom muaj qhov zoo thiab zoo sib xws. Tsis tas li ntawd, duplex stainless hlau yuav tsum tau ua tib zoo saib xyuas cov khoom siv hluav taws xob thaum lub sij hawm vuam kom tswj tau qhov xav tau microstructure thiab cov khoom siv.

Cov cuab yeej tshwj xeeb thiab cov kws tshaj lij feem ntau yuav tsum tau los daws cov teeb meem tshwj xeeb uas cuam tshuam nrog duplex steel vuam, xws li kev tswj xyuas qhov kub thiab txias kom tsis txhob muaj qhov cuam tshuam ntau dhau ntawm cheeb tsam (HAZ). Zuag qhia tag nrho, kev tsim cov txheej txheem ntawm duplex steel welded raj muaj cov kev txiav txim siab tshwj xeeb thiab cov txheej txheem ua kom haum rau cov yam ntxwv tshwj xeeb ntawm duplex stainless hlau kom ntseeg tau tias cov khoom lag luam ruaj khov thiab txhim khu kev qha.
