- Cov kav dej raug sim siv lub spectrometer kom ntseeg tau tias cov khoom siv tau ua raws li cov qauv ASTM A778.
2. Kev Siv Nyiaj Txiag Siab
- Peb cov kav dej yog tsim los siv ncaj seam welding yam tsis muaj annealing, ua rau lawv pheej yig dua seamless los yog annealed kav. Haum rau kev tsim kho, infrastructure, thiab lwm yam kev siv, txo cov nqi tsim khoom.
- Peb cov kav dej yog polished kom yooj yim txiav thiab vuam, txo cov nqi tsim khoom thiab kev teeb tsa.
3. Nto Zoo
- A778 Yeeb Nkab tau txais kev xaiv, passivation, thiab polishing los txhim kho corrosion kuj thiab ua tiav qhov siab du du (Ra Tsawg dua lossis sib npaug li 0.4μm), ua rau nws zoo tagnrho rau kev tsim kho, rooj tog zaum, thiab tsim sab hauv.
- Cov kav dej tau dhau qhov kev ntsuas qhov ntev thiab roughness los xyuas kom meej qhov zoo raws li cov neeg siv khoom xav tau; roughness qib tuaj yeem ua raws li qhov project specifications.
4. Weld Zoo
- Peb siv ERW vuam thev naus laus zis los xyuas kom meej qhov du, tiaj tus weld nto thiab zoo li qub, tsis muaj kev cuam tshuam rau kev zoo nkauj.
- Cov kav dej raug kuaj xyuas cov cuab yeej cuab tam kom ntseeg tau tias lawv lub zog tensile thiab ductility yog haum rau cov qauv siv thiab cov khoom siv zoo nkauj.

FAQ
Q: Cov ntawv thov twg yog ASTM A778 cov kav dej haum rau?
A: Cov kav dej no tsim nyog rau cov qauv kev txhawb nqa thiab tsis yog - cov ntawv thov kev siv dag zog, xws li cov tes tuav, cov ntsia hlau, rooj tog zaum, cov kav dej sab hauv, thiab cov kev txhawb nqa tsis muaj zog.
Q: Cov kav dej A778 puas tuaj yeem welded lossis machined hauv thaj teb?
A: Yog, cov kav dej no muaj qhov zoo tshaj plaws weldability. Lawv tuaj yeem raug txiav, khoov, polished, lossis flared yam tsis muaj kev cuam tshuam kev ua haujlwm.
Q: Koj puas tuaj yeem muab qhov loj me lossis ntim khoom?
A: Yog lawm, peb muab cov kev pabcuam hloov kho tau yooj yim, suav nrog cov yeeb nkab sab nraud, phab ntsa tuab, thiab ntev; pickling, passivation, los yog polishing nto kho; thiab ntim khoom xws li ntoo crates, PVC wrapping zaj duab xis, thiab kev tiv thaiv xeb.
