Cov txheej txheem ntau lawm ntawm 20G seamless kav yuav muab faib ua ob txoj kev: txias txias thiab kub dov.
Cov txheej txheem tsim khoom ntawm cov kav dej txias-dov seamless feem ntau yog qhov nyuaj dua li cov kav dej kub-dov.
Precision dov kav yuav tsum tau peb-yob nruam dov thiab extrusion txoj kev. Tom qab ntawd, yuav tsum tau kuaj xyuas pwm.
Yog tias cov txheej txheej saum npoo tsis pib thiab cov kab nrib pleb tshwm sim, cov kav hlau puag ncig yuav tsum tau txiav rau hauv cov kab uas ntev li ib 'meter' ntev siv lub tshuab txiav.
20G yog dab tsi?
20G yog ib hom zoo carbon structural steel, feem ntau siv nyob rau hauv zus tau tej cov boiler hlab thiab siab hlab ntsha vim nws zoo heev mechanical zog thiab kub kuj.
20Gyog cov khoom steel ntawm GB 5310- 2008. GB 5310- 2008 tus qauv siv tau rau cov raj seamless rau kev ua cov boiler uas nws lub siab siab los yog siab dua thiab seamless raj siv los ua cov kav dej.
GB 5310 yog tus qauv Suav uas qhia txog cov kev qhia tshwj xeeb rau seamless steel raj siv nyob rau hauv high-pressure boilers. Lub npe "20G" yog hais txog cov khoom siv qib ntawm cov raj no, qhia tias lawv yog tsim los ntawm 20G steel, cov hlau tsis tshua muaj carbon uas paub txog nws cov khoom siv hluav taws xob zoo heev thiab lub zog tensile siab.
GB 5310 yog tus qauv rau cov raj seamless siv nyob rau hauv high-pressure steam boilers thiab pipelines. Daim ntawv thov tseem ceeb rau GB 5310 cov raj yog raws li cov raj xa dej siab hauv cov haujlwm boiler. Cov raj no tuaj yeem siv rau superheaters, reheaters, thiab cua tshuab.
GB 5310 tus qauv siv rau cov raj ua los ntawm cov ntaub ntawv xws li:
10#, 20#, 45#
15Mn, 20Mn, 45Mn
30Mn2, 20Mn2, 15CrMoG
12Cr1Mo1VG, 12CrMoG
Kev ntsuas PMI rau GB5310 20G steel
Kev Ntsuas Cov Khoom Siv Zoo (PMI) yog ua tiav ntawm GB5310 20G steel los txiav txim siab cov khoom muaj pes tsawg leeg thiab xyuas kom meej tias nws ua tau raws li cov kev cai ntawm cov tshuaj muaj pes tsawg leeg.
