ASTM A209 Superheater Tubes Hauv Boiler
Khoom siv thiab Specification
ASTM A209 yog tus qauv tshwj xeeb rau seamless carbon-molybdenum alloy-steel boiler thiab superheater raj. Cov raj no feem ntau yog siv rau hauv cov ntawv thov kub xws li boilers thiab superheaters hauv cov chaw tsim hluav taws xob thiab cov chaw tsim khoom.
Cov khoom siv hauv ASTM A209 raj yog cov hlau tsis tshua muaj hlau uas muaj molybdenum, uas txhim kho nws lub zog thiab corrosion kuj ntawm qhov kub siab. Cov raj yog tsim los siv cov txheej txheem seamless thiab muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab thicknesses kom tau raws li cov kev cai tshwj xeeb.
Cov yam ntxwv tseem ceeb
Kev kub siab ua haujlwm: ASTM A209 cov raj yog tsim los tiv thaiv qhov kub thiab txias siab feem ntau pom nyob rau hauv boilers thiab superheaters.
Corrosion kuj: Qhov sib ntxiv ntawm molybdenum txhim kho corrosion kuj ntawm cov hlab, ua rau lawv haum rau siv nyob rau hauv ib puag ncig hnyav.
Seamless kev tsim kho: Cov txheej txheem tsim seamless ua kom muaj kev sib haum xeeb thiab lub zog thoob plaws hauv lub raj, txo qhov kev pheej hmoo ntawm kev xau lossis tsis ua haujlwm.
Cov khoom siv zoo heev: ASTM A209 cov raj muaj lub zog tensile zoo, lub zog tawm los, thiab cov khoom elongation, ua kom ntseeg tau tias kev ua tau zoo raws li qhov xav tau.

Kev ua tau zoo
ASTM A209 raj muaj cov txheej txheem kev ua tau zoo, ua rau lawv haum rau ntau yam kev siv kub. Cov hlab ntsha tuaj yeem tiv taus cov kev mob siab thiab tswj lawv cov qauv kev ncaj ncees txawm tias qhov kub siab. Lawv muaj qhov zoo weldability thiab tuaj yeem tsim tau yooj yim thiab fabricated.
Qib Steel
ASTM A209 raj muaj nyob rau hauv ob qib steel: Qib T1 thiab Qib T1a. Cov qib no txawv ntawm lawv cov ntsiab lus carbon, nrog Qib T1a muaj cov ntsiab lus qis dua.
Daim ntawv thov
ASTM A209 superheater raj yog siv dav hauv boilers thiab superheaters hauv cov chaw tsim hluav taws xob, refineries, petrochemical nroj tsuag, thiab lwm yam chaw tsim khoom. Lawv tau tsim tshwj xeeb los tiv thaiv qhov kub thiab txias, ua rau lawv haum rau siv hauv cov ntawv thov tseem ceeb uas qhov kev ua tau zoo yog qhov tseem ceeb.
Cov qhab nia xaiv tau
Thaum ASTM A209 cov raj feem ntau siv rau hauv cov ntawv thov kub, muaj lwm cov qib uas yuav tsim nyog rau cov kev cai tshwj xeeb. Qee cov qhab nia muaj xws li ASTM A213 T11, ASTM A335 P11, thiab ASTM A199 T11. Cov qib no muaj cov khoom zoo sib xws thiab tuaj yeem suav tias yog lwm txoj hauv kev nyob ntawm cov ntawv thov tshwj xeeb thiab kev ua haujlwm.
