GB5310yog tus qauv code ntawm Tuam Tshoj lub teb chaws tus qauv "Seamless Steel Pipes rauCov Boilers Siab Siab", uas qhia txog cov kev cai rau cov kav hlau tsis muaj seamless rau cov boilers siab thiab cov kav dej pa. Tus qauv GB5310 npog ntau yam hlau qib kom tau raws li cov kev xav tau ntawm daim ntawv thov sib txawv. Cov hauv qab no yog qee qib thiab lawv cov kev lag luam thov:

20G20G yog ib qho ntawm cov qib siv dav tshaj plaws hauv GB5310, nrog rau cov khoom tseem ceeb ntawm carbon, manganese thiab silicon. Nws muaj cov khoom siv kho tshuab zoo thiab cov khoom siv vuam, thiab feem ntau yog siv los tsim cov khoom tseem ceeb xws li phab ntsa txias dej, superheaters, economizers thiab nruas hauv chaw nres tsheb fais fab boilers.

15CrMoGCov hlau no muaj chromium thiab molybdenum, thiab muaj lub zog kub thiab tiv taus oxidation. 15CrMoG seamless steel kav feem ntau siv los tsim cov kav dej kub thiab siab siab, cov taub hau thiab cov kav dej, thiab lwm yam, thiab siv dav hauv kev lag luam petrochemical thiab fais fab.

12Cr1MoVG: Muaj cov ntsiab lus chromium, molybdenum thiab vanadium siab, nrog kev ua haujlwm kub zoo heev thiab ruaj khov mus sij hawm ntev. Cov kav hlau tsis muaj qhov sib txuas ntawm qib no feem ntau siv rau hauv cov boilers kub thiab siab siab thiab cov khoom siv fais fab nuclear, tshwj xeeb tshaj yog cov hloov pauv cua sov, cov kav dej ncu, thiab lwm yam.

Cov yeeb nkab hlau tsis muaj seamless no siv dav hauv kev tsim cov khoom tseem ceeb hauv qhov kub thiab txias siab xws li fais fab, petrochemical, thiab nuclear fais fab vim lawv cov tshuaj lom neeg tshwj xeeb thiab cov khoom siv kho tshuab. Los ntawm kev xaiv cov hlau zoo, kev nyab xeeb thiab kev ruaj khov ntawm cov khoom siv hauv qab qhov xwm txheej ua haujlwm hnyav tuaj yeem lav tau, thiab lub neej ua haujlwm tuaj yeem ntev dua.
