Hauv kev siv hauv kev lag luam, cov kav hlau steel ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev thauj mus los ntawm cov kua thiab roj.Cov kev lag luam sib txawv xav tau cov yeeb nkab steel tshwj xeeb, nyob ntawm lawv cov kev xav tau tshwj xeeb thiab qhov xwm txheej.Niaj hnub no, peb ua tib zoo saib ntawm qhov txawv tshaj plaw thiab lub zog muaj los ntawm peb cov khoom tseem ceeb steel yeeb nkab: ASTM A53 Gr.B boiler steel yeeb nkab, ASTM A192 yeeb nkab, thiab API 5L Gr.B seamless steel yeeb nkab.
ASTM A53 Gr.Bboiler steel yeeb nkab:
ASTM A53 GR.B boiler steel yeeb nkab yog qib ntawm cov yeeb nkab steel tsim los rau kev siv kub thiab kub siab hauv boilers thiab kub exchangers.Nws yog tsim los siv cov pa roj carbon thiab alloying ntsiab rau superior durability thiab tsis kam mus rau kev nyuaj siab corrosion cracking.Tsis tas li ntawd, ASTM A53 Gr.B boiler steel kav muaj cov ntsiab lus carbon ntau dua li cov kav dej txheem, muab ntau zog thiab toughness.
ASTM A192 Yeeb Nkab:
Lwm cov khoom siv zoo tshaj plaws steel yeeb nkab yog ASTM A192 yeeb nkab, feem ntau siv hauv cov tshuab hluav taws xob siab thiab cov khoom siv hluav taws xob.ASTM A192 yeeb nkab yog tsim los ntawm cov pa roj carbon zoo nrog cov khoom siv kho tshuab zoo heev thiab ua haujlwm zoo heev rau sab hauv thiab sab nraud.
API 5L GR.B seamless steel yeeb nkab:
API 5L GR.B yog tsim los rau kev thauj mus los ntawm cov pa roj, roj thiab lwm yam kua dej.Seamless steel kav yog ib qho kev xaiv nrov hauv kev lag luam roj thiab roj.Cov khoom siv steel yeeb nkab no muaj kev tiv thaiv zoo heev rau cov neeg kho tshuab kev nyuaj siab thiab corrosion, ua rau nws zoo tagnrho rau cov kev xav tau.
Los ntawm boilers mus rau cov roj thiab roj kis kab, ASTM A53 Gr.Bboiler steel yeeb nkabASTM A192 yeeb nkab thiab API 5L Gr.B seamless steel yeeb nkab muaj kev siv tshwj xeeb hauv ntau qhov kev lag luam.Cov khoom siv tshwj xeeb steel yeeb nkab no muaj cov khoom zoo xws li kub tsis kam, corrosion kuj thiab zoo heev txhua yam muaj zog.
