1. Dab tsi yog cov qauv rau seamless carbon steel kav?
Common Standards:
Lub teb chaws tus qauv: GB / T 8162 (Structural Pipes), GB / T 8163 (Fluid Pipes), GB / T 3087 (Low thiab Nruab Nrab Siab Boiler Tubes), GB / T 5310 (High Pressure Boiler Tubes)
American Standards: ASTM A53, A106, API 5L
Cov qauv European: EN 10216-2, DIN 17175
Japanese Standards: JIS G3454, G3456, G3461
Peb tuaj yeem tsim raws li cov neeg siv khoom- cov qauv tshwj xeeb thiab muab cov ntaub ntawv pov thawj thiab cov ntawv xeem.
2. Dab tsi yog cov txheej txheem ntau lawm rau seamless carbon steel kav?
Cov txheej txheem tseem ceeb:
Kub- dov seamless kav: Kub kub, ceev sib sau, loj specifications, thicker phab ntsa, nruab nrab nqi, haum rau loj- kab, tuab-walled kav.
Txias -draw / txias- dov seamless kav: siab qhov tseeb, du nto, cov phab ntsa tuab, me me ovality, haum rau precision machinery, hydraulics, thiab automotive daim ntaub ntawv.
Kub- nthuav dav seamless raj: Loj- txoj kab uas hla seamless yog tsim los ntawm txoj kab uas hla nthuav dav kom tau raws li qhov xav tau ntawm cov phiaj xwm loj - txoj kab uas hla.
3. Tus qauv loj npaum li cas ntawm seamless carbon steel hlab?
Standard ntau yam:
Sab nraud txoj kab uas hla: 10mm - 720mm
Phab ntsa thickness: 1.5mm-100mm
Ntev: Txuj ntev 5.8m, 6m, 11.8m, 12m, lossis ntev npaum li cas raws li cov neeg siv khoom xav tau.
Tshwj xeeb specifications yuav customized nrog pwm.
4. Dab tsi yog qhov permissible phab ntsa thickness sib txawv? Dab tsi yog qib precision?
Nyob ntawm cov qauv, phab ntsa thickness sib txawv feem ntau yog:
Kub- dov raj: ± 10% lossis ± 12.5%
Txias-kos / txias- dov precision raj: ± 5% lossis ntau dua qhov tseeb.
Peb tuaj yeem muab siab - cov raj xaim kom ua tau raws li qhov yuav tsum tau ua ntawm machining, hydraulic thooj voos kheej kheej, cov kabmob raj, thiab lwm yam.
5. Ntev npaum li cas ntawm seamless carbon steel raj tuaj yeem kho tau?
Yog lawm. Cov qauv ntev yog qhov tsis sib xws lossis 6m / 12m, tab sis kuj tuaj yeem txiav rau txhua qhov ntev xws li 3m, 4m, 5m, 7m, thiab lwm yam, raws li cov neeg siv khoom xav tau. Rau kev lag luam tawm, peb feem ntau optimize qhov ntev raws li lub thawv loj kom muaj peev xwm thauj khoom thiab txo cov nqi thauj khoom.
