** 1. Yog seamless yeeb nkab kim? **
Yog lawm, cov kav dej seamless feem ntau kim dua welded kav (piv txwv li ntawm lawv cov khoom lag luam hauv av loj, lossis cov khoom siv ntau dua, thiab cov khoom siv stricter. Txoj kev tsis tuaj hauv Welds kuj yuav tsum tau muaj cov tswv yim ntau lawm, ua rau muaj nqi siab dua.
** 2. Thaum twg siv seamless yeeb nkab? **
Seamless kav yog nyiam rau cov siab-siab, siab-kub, lossis xeb ib puag ncig uas muaj kev cai ncaj ncees yog qhov tseem ceeb. Cov kev siv cov roj uas muaj roj thiab roj av, tshuaj siv hluav taws xob, kev ua haujlwm siv, cov tshuab hydraulic, thiab kev ntseeg siab, nyob rau hauv kev ntseeg siab nyob hauv siab heev.
** 3. Uas yog qhov zoo dua, seamless lossis ERW YEEB? **
Tsis yog qhov ua tau los ntawm cov "zoo dua" yog nyob ntawm daim ntawv thov. Seamless pipes excel nyob rau hauv kev ntxhov siab, muaj kev kub siab ib puag ncig vim lawv cov kev sib tw thiab tsis muaj weld seams. ERW (hluav taws xob tiv thaiv welded) kav ntev dua rau cov ntawv thov qis rau qis-nruab nrab (piv txwv li, kev siv dej, kev siv). ERW yuav muaj cov ntsiab lus tsis muaj zog ntawm Weld, tab sis cov kev siv vuam niaj hnub tau txhim kho lawv cov khoom zoo.
** 4. Dab tsi qib yog seamless yeeb nkab? **
Seamless Pipes tuaj hauv ntau qib nyob ntawm cov khoom thiab cov qauv:
- ** QIB GRASTER ***: ASTM A106 (cov kev pabcuam kub siab), ASTM A53 (AVER GR (Roj \/ Roj \/ Roj \/ Roj \/ Roj \/ Roj \/ Roj \/ Roj \/ roj av).
- ** STESSM A312 (piv txwv li, Tp304 rau corrosion tsis kam).
- ** ALLOY STEEL **: ASTM A335 (piv txwv, P11, P22 rau kev ua haujlwm siab).
** 5. Dab tsi yog 3 qib ntawm cov yeeb nkab steel? **
Peb qib ntawm cov yeeb nkab steel muaj xws li:
1. ** API 5L Qib B **: Siv nyob rau hauv cov roj thiab roj thauj mus los.
2. ** ASTM A106 qib b **: Rau kev pab kub hauv cov nroj tsuag hluav taws xob thiab kev ua kom zoo.
3. ** ASTM A53 Qib B **: General-General-General Carbon Hlau Yeeb Rau Yaig, Txheej Txheem, thiab Tsawg-siab siv.
(Cov qib sib txawv raws cov khoom muaj pes tsawg leeg, cov khoom siv neeg siv tshuab, thiab cov ntawv thov npaj.)
