ASME SA213 TP321yog ib qho seamless ferritic thiab austenitic stainless hlau raj tsim los rau siab kub kev pab cuam.UNS S32100 stainless hlauyog ib feem ntawm austenitic stainless hlau tsev neeg thiab yog alloyed nrog titanium los txhim kho nws corrosion kuj thiab high-temperature zog. Txawm li cas los xij, thaum nws los txog rau cov ntawv thov hauv kev lag luam boiler, qee yam ntawm cov hlau tsis muaj steel zoo dua li lwm tus. Ib yam li ntawd yogASME SA213 TP321 UNS S32100 stainless hlau seamless raj, uas yog feem ntau siv nyob rau hauv boilers.
Bolier Tubes yog dab tsi?
Boilersua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem kev lag luam, los ntawm kev tsim hluav taws xob mus rau kev tsim tshuaj lom neeg. Lawv yog lub luag hauj lwm rau hloov dej mus rau hauv chav dej, uas tom qab ntawd siv rau ntau lub hom phiaj. Txhawm rau ua qhov haujlwm no kom zoo, boilers yuav tsum tau tsim los ntawm cov ntaub ntawv uas tuaj yeem tiv taus qhov kub thiab txias.
Vim li cas thiaj xaiv ASME SA213 TP321 Khoom?
ASME SA213 TP321yog tus qauv specification rau seamless ferritic thiab austenitic alloy-steel boiler, superheater, thiab tshav kub exchanger raj. Qhov no aisi 321 stainless hlau muaj titanium, uas ua rau nws txhim kho qhov kub thiab txias tsis kam thiab txhim kho corrosion kuj. UNS S32100 stainless hlau yog qhov hloov pauv ntawm 321 stainless hlau, thiab nws tseem hu uaASTM A 213 Qib 321 stainless hlau. EN 1.4541 aisi 321 tubingmuaj kev tiv thaiv zoo heev rau intergranular corrosion thaum raug kub hauv chromium carbide nag lossis daus ntawm 427 degree txog 816 degree.
ASTM A213 TP321 stainless hlau raj ua rau lawv zoo tagnrho rau siv nyob rau hauv boilers qhov chaw uas lawv raug kub thiab corrosive ib puag ncig.ASTM 321 stainless hlaukuj tseem tiv taus ntau hom kev ntxhov siab corrosion cracking, ua rau lawv muaj kev ntseeg siab rau kev siv boiler.
ASTM A213 UNS S32100 stainless hlauyog qhov kev xaiv nrov rau kev siv boiler vim tias nws muaj qhov tshwj xeeb kub-kub corrosion kuj, nrog rau kev nkag siab zoo heev. Cov khoom no uasus321 khoomcov khoom siv zoo heev rau kev siv hauv superheater thiab reheater tubing, nrog rau hauv cov kav dej kub kub.
