Cov khoom ua raws li qhov yuav tsum tau uaGB5310 tus qauv, siv cov khoom zoo15CrMoGCov hlau chromium-molybdenum alloy (Cr: 1.0-1.5%, Mo: 0.45-0.60%), thiab yog ua los ntawm cov qauv tsis muaj qhov sib txuas los ntawm kev dov kub thiab cov txheej txheem kos duab txias, nrog rau ob qho tib si lub zog siab (lub zog tensile ≥ 440MPa) thiab tiv taus kub (qhov kub siv tau ≤ 580 ℃). Nws cov khoom tiv thaiv oxidation thiab tiv thaiv creep zoo heev, thiab nws tuaj yeem tiv taus qhov siab siab ntawm cov pa dej thiab cov pa roj flue corrosion ntev, thiab nws lub neej ua haujlwm ntau dua 30% siab dua li cov kav hlau ib txwm muaj. Kev kuaj pom qhov tsis zoo ultrasonic, kev kuaj pom tam sim no eddy thiab kev sim siab dej tau ua tiav thoob plaws hauv cov txheej txheem kom ntseeg tau tias tsis muaj qhov tawg thiab tsis muaj qhov xau, thiab qib kev nyab xeeb mus txog qib ua tus thawj coj hauv kev lag luam.

Kev them nqi ntau qhov xwm txheej, kev sib phim meej ntawm cov kev xav tau
Tsim los rau cov khoom tseem ceeb xws li lub chaw ua hluav taws xob boilers, superheaters, thiab reheaters, nws yog qhov tsim nyog rau supercritical thiab subcritical units thiab cov txheej txheem rov qab cua sov pov tseg. Nws kuj tseem siv dav hauv cov haujlwm kav dej kub thiab siab hauv cov teb ntawm petrochemicals, kev lag luam tshuaj lom neeg thee, thiab cogeneration. Nws txhawb kev hloov kho yooj yim ntawm cov kab sab nraud ntawm 25-762mm thiab phab ntsa tuab ntawm 2.5-120mm kom ua tau raws li qhov yuav tsum tau teeb tsa ntawm cov xwm txheej ua haujlwm nyuaj, pab cov neeg siv khoom txo cov nqi kho thiab txhim kho kev siv hluav taws xob.
