1. ** FFW txhais li cas hauv cov raj? **
FFW feem ntau feem ntau sawv rau ** Fillet Weld ** hauv piping thiab vuam cov ntsiab lus. Nws yog hais txog weld ntawm kwv yees li daim duab peb sab kev sib txuas lus koom nrog ob qhov chaw (feem ntau sib tshuam lossis ze-sib tshuam). Feem ntau, nws tuaj yeem qee zaum sawv ntsug rau "Puv Full Weld" lossis "Full Fulty Weld," tab sis "Filet Weld" yog qhov tseem ceeb tshaj plaws cov ntsiab lus.
2. ** Tuaj yeem ERW cov yeeb nkab raug seamless? **
** TSIS MUAJ. ** ERW (hluav taws xob tiv thaiv welded) yeeb nkab inherently muaj ib leeg. Cov txheej txheem tsim khoom lag luam cuam tshuam nrog steel sawb / tiab rau hauv lub tog raj kheej thiab tom qab ntawd vuam lub suab nrov ntev siv hluav taws xob cua sov siv cua sov. Seamless yeeb (sms) yog tsim los ntawm tho ib lub nplua nuj nqi, tsis muaj welded seam.
3. ** Cov yeeb nkab tsis zoo li cas? **
Lub ntsiab tseem ceeb ntawm cov ntaub yeeb nkab piv rau seamless yeeb yog:
* ** Weld Seam Tsis Txaus Ntseeg: ** Thaj chaw kub-cuam tshuam rau kev ua kom muaj zog Weld tuaj yeem ua rau muaj kev ntxhov siab ntau yam lossis cuam tshuam nrog cov yeeb nkab tub nyiag.
* ** YUAV TSUM TAU KEV PAB: ** Yuav tsum tau kuaj cov hlua khi (ect) zoo li Weld sab xis tam sim no tsis muaj peev xwm tsis muaj kev sib luag.
* ** Kev ntsuas siab / qhov kub thiab txias: ** Feem ntau muaj qis dua siab thiab kub ntsuas piv rau cov yeeb nkab uas tsis tseem ceeb thiab cov khoom siv, tshwj xeeb tshaj yog rau cov kev pabcuam tseem ceeb.
* ** Muaj peev xwm rau ovality / waviness: ** Qee zaum muaj qhov tsaus lossis nrawm dua li cov yeeb nkab uas tsis yog vim yog cov txheej txheem sib dhos.
4. ** Tuaj yeem ERW cov kav dej yuav rov ua dua tshiab? **
** Yog lawm. ** ERW cov yeeb nkab ua los ntawm cov hlau lossis cov hlau me-alloy yog siv tau yooj yim. Zoo li cov khoom lag luam steel feem ntau, nws tuaj yeem sau raws li cov qauv standrap, melted hauv hauv cov khoom cub hluav taws xob (EAFS) lossis rov ua kom cov khoom tshiab rau hauv cov yeeb nkab steel, suav nrog cov yeeb nkab tshiab. Recycling hlau yog tus qauv thiab cov txheej txheem kev lag luam muaj txiaj ntsig.
5. ** Yog ERW YEEB YEEB NKAB HLUB STINLESS? **
** Tsis tas. ** ERW yog hais txog ** kev tsim khoom ** (hluav taws xob tiv thaiv vuam), * tsis yog * cov khoom siv. ERW cov yeeb nkab feem ntau yog tsim los ntawm ** hlau steel **. Txawm li cas los xij, nws ** tuaj yeem ** tuaj yeem tsim los ntawm ** ** stainless hlau ** qib yog tias teev. Yog li, thaum cov yeeb nkab feem ntau yog carbon hlau, stainless hlau, uas yuav tsum muaj cov kev siv corrosion tsis kam ua ke nrog tus nqi cuam tshuam ntawm cov txheej txheem erw.
