Yog tias koj tab tom nrhiav kev tiv thaiv corrosion-resistant stainless hlau welded raj rau high-efficiency tshav kub exchanger systems, peb muab ASTM A249 TP304 stainless hlau welded raj rau tshav kub exchangers, tshwj xeeb yog tsim los rau raj bundles nyob rau hauv cov tshuaj, tshuaj, zaub mov thiab lub zog industries.
Peb ASTM A249 TP304 welded tubes undergo precision vuam, pickling thiab tov annealing, uas ua rau ib tug du nto thiab uniform phab ntsa thickness. Muaj nyob rau hauv diameters los ntawm 6mm mus rau 168.3mm thiab customizable ntev rau cov neeg yuav tsum tau, lawv yog zoo tagnrho rau manufacturing raj bundles rau tshav kub exchangers thiab kev cai systems. TP304 stainless hlau boiler raj muaj kev tiv thaiv corrosion zoo heev, oxidation kuj thiab lub sij hawm ntev kub stability, ua kom ntseeg tau kev ua tau zoo hauv ntau yam xov xwm thiab kev ua haujlwm.
Txhawm rau kom ntseeg tau cov khoom zoo, txhua lub raj muaj xws li Cov Khoom Siv Xeem Ntawv Pov Thawj (MTC), kev tshuaj xyuas qhov ntev, kuaj pom qhov tsis xws luag thiab tsis muaj kev puas tsuaj (UT / PT), kom ntseeg tau tias ua tau raws li ASTM A249 cov qauv thiab cov neeg siv khoom kub siab ua haujlwm.
Dab tsi yog qhov txawv ntawm 304L thiab 304H raj?
Qhov sib txawv ntawm 304L thiab 304H raj yog nyob rau hauv lawv cov ntsiab lus carbon. 304L muaj cov ntsiab lus qis dua, nrog qhov siab tshaj plaws ntawm 0.03%, thaum 304H muaj cov ntsiab lus ntau dua, xws li 0.04% txog 0.1%. Cov ntaub ntawv nrog cov ntsiab lus qis dua yog qhov tsim nyog rau vuam, thaum cov ntsiab lus carbon siab dua muab lub zog ntau dua. UNS S30403 stainless hlau raj rau cov khoom siv hluav taws xob tuaj yeem tiv taus qhov kub txog li 870 degrees Celsius nyob rau hauv kev siv tsis tu ncua thiab mus txog 925 degrees Celsius nyob rau hauv kev siv tas li.
