** 1. Uas yog qhov zoo dua, seamless lossis ERW YEEB? **
Kev xaiv yog nyob ntawm daim ntawv thov:
- ** SEAMLESS PIPES ** Tsis muaj lub zog welded, muaj zog dua, thiab kev ntseeg tau rau cov kev muaj zog, thiab cov roj thiab roj av).
- ** ERW (hluav taws xob tiv thaiv welded) kav dej ** zoo rau cov ntaub ntawv thov tsawg (piv txwv li, dej pipelines, kev siv cov qauv teeb tsa). Seamless yog "zoo dua" rau kev ua tau tseem ceeb, tab sis ERW muaj kev lag luam ntau dua rau cov qauv siv.
** 2. Qhov twg yog qhov zoo dua, seamless lossis welded yeeb nkab? **
- ** SEAMLESS PIPES ** Tshaj tawm hauv lub zog, kev nyab xeeb, thiab xwm yeem, zoo nkauj rau cov xwm txheej huab.
- ** WELDED PIPES ** (suav nrog ERW, LSAW, lossis pom) yog cov haujlwm pheej yig dua thiab ua haujlwm zoo rau cov kav dej qis \/ nruab nrab, HVAC). Qhov kev xaiv "zoo dua" yog nyob ntawm kev siv nyiaj siv, cov kev xav tau lub siab, thiab ib puag ncig cov khoom.
** 3. Dab tsi yog erw yeeb siv rau? **
ERW kav muaj feem ntau siv rau:
- Qes \/ nruab nrab-nruab nrab kua \/ roj thauj (dej, roj, nkev).
- Cov ntawv thov kev tsim kho (kev tsim kho, fencing, scaffolding).
- Cov khoom siv tsheb, rooj tog zaum, thiab kev tsim khoom lag luam.
** 4. Dab tsi yog qhov txawv ntawm seamless cov yeeb nkab thiab kab yeeb nkab? **
- ** Seamless yeeb nkab ** Yog hais txog kev tsim txoj kev (tsis muaj Weld).
- ** LINE YEEB ** Yog hais txog kev siv siv hauv cov raj xa hluav taws xob rau kev haus dej \/ roj. Kab kav dej tuaj yeem yog seamless lossis welded (piv txwv li, erw, lsaw). Kab xaub kav yuav tsum ntsib cov qauv Stricter (piv txwv li, API 5L) rau kev muaj zog thiab kev ua siab ntev hauv ib puag ncig hnyav.
** 5. Thaum twg siv seamless yeeb nkab? **
Siv seamless kav rau:
- Kev kub siab \/ siab \/ lub tshuab ntsuas kub (piv txwv li, boilers, refineries).
- Corrosive lossis kua dej muaj kev puas tsuaj (kev ua yeeb yam).
- Cov ntawv thov tseem ceeb uas yuav tsum tau xau dej tsis kam (subsea, aerospace).
- Thaum cov qauv kev cai lij choj yuam kev uas tsis sib xws (piv txwv li, ASME B31.3 rau cov piping process).
