ASTM A249 TP321H stainless hlau kav feem ntau yog tsim los ntawm txias dov, txias kos duab thiab lwm yam txheej txheem ntau lawm, thiab ua tiav cov txheej txheem tom qab kho xws li kev kho cua sov + pickling. SS 321H Welded Tube yuav tsum tau kuaj xyuas hydraulic thaum lub sijhawm tsim khoom kom ntseeg tau tias tsis muaj qhov xau los yog seepage raws li tus nqi siab.
ASTM A249 Stainless Steel 321H Cold Drawn Tube muaj kev tiv thaiv siab rau intergranular corrosion thiab muaj corrosion kuj zoo rau qee cov organic thiab inorganic acids. Cov khoom siv stainless hlau seamless kav yog kuaj rau corrosion kuj raws li tus qauv lossis kev pom zoo sib koom ua ke los xyuas kom meej tias tsis muaj qhov cuam tshuam ntawm intergranular corrosion.
Vim hais tias ASTM A249 TP321H boiler raj muaj cov corrosion kuj zoo heev thiab txhua yam khoom, tshwj xeeb tshaj yog siv rau kev ua haujlwm mus sij hawm ntev hauv qhov kub thiab txias xws li cov cua kub exchangers, boiler superheater kav, cua kub exchanger kav, chav kav, thiab lwm yam.
