Ua ntej, cia peb tham txog cov khoom siv ntawmASTM A335 P22Cov yeeb nkab hlau sib xyaw. Cov yeeb nkab hlau no siv cov hlau zoo carbon lossis cov hlau sib xyaw ua cov khoom siv tseem ceeb thiab ua los ntawm kev kos duab txias lossis cov txheej txheem kub dov. Kev tswj hwm cov ntsiab lus carbon, cov ntsiab lus sib xyaw thiab cov ntsiab lus me me hauv cov yeeb nkab hlau ua kom muaj zog thiab tawv ntawm cov yeeb nkab hlau. Tsis tas li ntawd, qhov kev tiv thaiv corrosion ntawm ASTM A335 P22 cov yeeb nkab hlau sib xyaw kuj zoo heev, thiab nws tuaj yeem tswj nws cov kev ua tau zoo thiab lub neej ua haujlwm ntev hauv qhov chaw nyuaj.
Tom ntej no, cia peb kawm txog cov txheej txheem tsim khoom ntawmASTM A335 P22Cov yeeb nkab hlau sib xyaw. Cov txheej txheem tsim khoom feem ntau suav nrog cov kev sib txuas tseem ceeb xws li kev sib xyaw, dov thiab kev kho cua sov. Thaum lub sijhawm ua cov txheej txheem sib xyaw, cov khoom siv raw raug cua sov rau lub xeev molten thiab cov khoom sib xyaw tsim nyog raug ntxiv kom tau txais cov tshuaj lom neeg thiab cov qauv sib xyaw xav tau. Thaum lub sijhawm ua cov txheej txheem dov, qhov tseeb ntawm qhov ntev, qhov zoo ntawm qhov chaw thiab cov khoom siv kho tshuab ntawm cov yeeb nkab hlau tau ua kom ntseeg tau los ntawm kev tswj hwm cov kev ntsuas xws li qhov kub dov, qhov ceev thiab kev hloov pauv. Thaum kawg, qhov txuas kho cua sov pab tshem tawm cov kev ntxhov siab seem hauv cov yeeb nkab hlau thiab txhim kho nws qhov ruaj khov thiab ruaj khov.
Cov yam ntxwv ntawm kev ua tau zoo ntawmASTM A335 P22Cov yeeb nkab hlau sib xyaw kuj yog ib qho ntawm cov laj thawj rau nws qhov nrov. Ua ntej tshaj plaws, cov yeeb nkab hlau muaj lub zog siab thiab tawv, tuaj yeem tiv taus siab thiab cuam tshuam, thiab ua tau raws li qhov xav tau ntawm ntau yam kev ua haujlwm nyuaj. Qhov thib ob, nws muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus kev yaig ntawm ntau yam tshuaj lom neeg kom ntseeg tau tias kev ua haujlwm ruaj khov mus sij hawm ntev. Tsis tas li ntawd, ASTM A335 P22 cov yeeb nkab hlau sib xyaw kuj muaj kev tiv thaiv kub siab zoo thiab tuaj yeem tswj tau cov khoom siv kho tshuab thiab tshuaj lom neeg ruaj khov hauv qab qhov kub siab.
Nws yog vim muaj cov yam ntxwv zoo heev no uas ASTM A335 P22 alloy steel yeeb nkab tau siv dav hauv ntau qhov chaw. Hauv kev lag luam roj av thiab tshuaj lom neeg, cov yeeb nkab hlau yog siv los tsim cov kav dej kub thiab siab thiab cov khoom siv kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem ntau lawm. Hauv kev siv hluav taws xob,ASTM A335 P22Cov yeeb nkab hlau alloy yog siv dav hauv cov khoom siv tseem ceeb xws li boilers thiab superheaters, tiv taus qhov kub thiab txias siab thiab dej kub, muab kev lees paub txhim khu kev qha rau kev tsim hluav taws xob. Tsis tas li ntawd, hauv kev lag luam nuclear, cov yeeb nkab hlau kuj ua lub luag haujlwm tseem ceeb hauv kev tsim cov yeeb nkab thiab cov thawv hauv cov chaw tsim hluav taws xob nuclear kom ntseeg tau tias kev siv hluav taws xob nuclear muaj kev nyab xeeb.
Ntxiv rau cov cheeb tsam thov saum toj no,ASTM A335 P22Cov yeeb nkab hlau sib xyaw kuj tseem tuaj yeem hloov kho raws li cov neeg siv khoom xav tau kom ua tau raws li qhov xav tau siv hauv cov xwm txheej tshwj xeeb.
