1. Txij li feem ntau cov yeeb nkab fittings yog siv rau vuam, qhov kawg yog beveled los txhim kho vuam zoo, tawm hauv ib lub kaum ntse ntse thiab ntug. Qhov kev xav tau no yog nruj heev, nrog rau cov kev cai qhia txog ntug thickness, lub kaum sab xis, thiab kam rau ua ntau yam. Qhov saum npoo zoo thiab cov khoom siv kho tshuab yog qhov tseem ceeb tib yam li cov yeeb nkab. Rau kev yooj yim ntawm vuam, qib steel ntawm qhov haum yog tib yam li cov yeeb nkab txuas.
2. Tag nrho cov yeeb nkab fittings raug kho saum npoo. Hlau oxide nplai nyob rau sab hauv thiab sab nrauv raug tshem tawm los ntawm kev txhaj tshuaj blasting, ua raws li kev siv tshuaj tiv thaiv- xim xim. Qhov no yog qhov tsim nyog rau kev xa tawm, thiab tseem rau kev thauj mus los hauv tsev los pab txhawb kev xeb thiab oxidation tiv thaiv.
3. Kev ntim khoom: Rau cov khoom me me, xws li cov khoom xa tawm, cov ntoo crates ntawm kwv yees li 1 cubic meter yuav tsum tau. Tus qauv qhia tias tus naj npawb ntawm lub luj tshib nyob rau hauv xws li crates tsis tuaj yeem tshaj ib tuj. Kev ua zes (cov crates loj hauv cov me me) raug tso cai, tab sis qhov hnyav tag nrho feem ntau tsis tuaj yeem tshaj ib tuj. Cov fittings loj dua (piv txwv li, 24 ") yuav tsum tau ntim rau tus kheej. Tsis tas li ntawd, cov cim ntim yuav tsum qhia qhov ntev, qib steel, batch tooj, chaw tsim khoom lag luam, thiab lwm yam.
