GB3087 Seamless Steel Kav

GB3087 yog ib tus qauv hauv tebchaws uas qhia txog qhov yuav tsum tau ua rau Seamless Steel kav siv siv hauv kev tsim kho ntawm boilers thiab siab cov hlab. Tag nrho cov qauv kev tsim qauv yog ** GB / T 3087-2008 "Seamless cov hlau tub rau qis thiab nruab nrab siab boilers" **. Cov qauv no yog qhov tseem ceeb tshaj plaws hauv Suav teb cov khoom lag luam thiab cov haujlwm tsim khoom, tswj hwm cov kav dej tsim los ua haujlwm kom ntsuas kub thiab ntsuas.

Cov kav dej ua raws li cov qauv no yog tsim los ntawm cov roj carbon stick xws li 10, 20, 16mn, thiab lwm tus raws li tau teev tseg. Tus yam ntxwv tseem ceeb ntawm cov kav dej no yog lawv ** Seamless kev tsim kho **, txhais tau tias lawv tau tsim los ntawm cov khoom noj khoom haus uas tsis muaj rooj zaum. Qhov no seamless xwm yog qhov tseem ceeb raws li nws muab lub zog zoo tshaj plaws, thiab ua rau lawv muaj kev nyab xeeb dua rau cov ntawv thov tseem ceeb piv rau kev xaiv welded.

Cov khoom siv tshuab ntawm GB3087 hauv lub zog, suav nrog lub zog tensile, kom muaj zog ua kom tau tias lawv tuaj yeem tiv thaiv cov tshuab kev ntxhov siab thiab kub siab ntsib hauv boiler tshuab. Lawv tau tsim los siv nyob rau hauv ib cheeb tsam uas cov kev ua haujlwm siab ua haujlwm ib txwm tsis tshaj ib qho kev hloov kho, cov lus qhia rau qhov tsawg rau cov kev pabcuam nruab nrab.

** Cov ntawv thov tseem ceeb muaj: **
* ** Siv cov raj boiles: ** Siv ntau seem ntawm chav boilers, xws li cov raj ntoo hauv av, cov leeg ntoo super, acceler, thiab cov kav dej loj.
* ** Dej siab: ** Dej kub, dej kub, thiab lwm yam kua nias nyob rau hauv cov nroj tsuag.
* ** Kev hloov pauv kub: ** Haum rau kev siv rau hauv cov cua sov hloov pauv thiab condenser tubing uas txhim khu kev qha uas txhim khu kev qha ua tau zoo nyob rau hauv thermal cycling yuav tsum muaj.

Hauv cov ntsiab lus, GB3087 Boiler Steel Kav yog qhov tseem ceeb ntawm thermal zog tiam, cua sov tshuab, thiab ntau yam txheej txheem muaj. Lawv ua raws li lub tswv yim pom zoo ua kom muaj kev ua tau zoo ib yam, thiab tseem ceeb tshaj plaws, kev nyab xeeb} kub thiab high {{3} {{}} siab} kev tawm suab. Lawv yog cov timkhawv qhia txog lub luag haujlwm tseem ceeb ntawm cov qauv qauv hauv cov khoom siv hluav taws xob niaj hnub.
