Txij li feem ntau cov yeeb nkab fittings yog siv rau vuam, los txhim kho vuam zoo, qhov kawg yog beveled, 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 pib zoo ib yam li cov kav dej. Rau kev yooj yim ntawm vuam, qib steel ntawm cov fittings yog tib yam li cov kav dej txuas nrog.
Tag nrho cov yeeb nkab fittings raug kho saum npoo. Cov hlau oxide nplai nyob rau sab hauv thiab sab nrauv raug tshem tawm los ntawm kev tua 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.
Hais txog kev ntim khoom, rau cov yeeb nkab me me, xws li cov khoom xa tawm, cov ntoo crates ntawm kwv yees li 1 cubic meter yog xav 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 fittings loj dua hauv cov me me) raug tso cai, tab sis qhov hnyav tag nrho feem ntau tsis tuaj yeem tshaj ib tuj. Cov khoom siv loj dua (piv txwv li, 24 "qhov ntau thiab tsawg) yuav tsum tau ntim rau ib tus zuj zus. Tsis tas li ntawd, cov cim ntim yuav tsum qhia qhov ntev, qib steel, batch naj npawb, chaw tsim khoom lag luam, thiab lwm yam.
