FAQ
01.Dab tsi yog qhov txawv ntawm CCS Qib D thiab Qib A shipbuilding steel?
Qhov sib txawv tseem ceeb yog qhov ntsuas qhov ntsuas kub. Qib A tsis tas yuav muaj kev cuam tshuam (kuaj ntawm +20 degree), thaum Qib D raug kuaj ntawm-20 degreenrog qhov tsawg kawg nkaus lub zog nqus ntawm 27 Joules. Qib D kuj yuav tsum tau tua cov hlau thiab cov hmoov nplej zoo kom ua tau zoo dua - qhov kub thiab txias, ua kom haum rau cov dej hiav txwv txias uas Qib A yuav tsis zoo.
02.CCS Qib D puas tuaj yeem welded yam tsis muaj preheating?
03.Qhov kev kho cua sov twg kuv yuav tsum xaiv rau CCS Qib D daim hlau?
Nws nyob ntawm koj thickness thiab daim ntawv thov:
Raws li -rolled (AR): Haum rau thicknesses txog 35mm nyob rau hauv cov qauv.
Normalized (N): Pom zoo rau cov thicknesses siab tshaj 40mm los kho cov qauv nplej thiab xyuas kom muaj cov khoom siv sib xws.
TMCP: Nyiam rau cov phaj hnyav (tshaj 60mm) uas yuav tsum tau muaj zog toughness thiab zoo heev weldability.
Peb tuaj yeem tawm tswv yim raws li koj qhov kev xav tau tsim tshwj xeeb.
04.Koj puas muab - tog thib peb tshuaj xyuas thiab ntawv pov thawj?
kiag li. Peb muab tag nrho thib peb- cov kev pabcuam tshuaj xyuas los ntawm SGS, TUV, lossis BV, thiab tag nrho cov phaj tuaj nrog daim ntawv pov thawj zeb hauv qabEN 10204 Hom 3.1raws li tus qauv. Hom 3.2 ntawv pov thawj kuj muaj raws li qhov kev thov, ua tim khawv los ntawm koj pawg neeg xaiv tsa (ABS, LR, DNV, thiab lwm yam). Peb kuj tuaj yeem npaj kuaj ultrasonic (UT) thiab Z- kev ntsuas kev taw qhia raws li xav tau.
