Qhov curvature radius ntawmstainless hlau luj tshibyuav tsum tswj. Piv txwv li, yog tias lub vojvoog ntev yog 1.5D, lub vojvoog ntawm curvature yuav tsum nyob rau hauv qhov yuav tsum tau ua siab ntev.

Txij li thaum feem ntau ntawm cov yeeb nkab fittings yog siv rau vuam, txhawm rau txhim kho qhov vuam zoo, qhov kawg tau hloov mus rau hauv grooves, nrog rau qee lub kaum ntse ntse thiab ib qho ntug. Qhov kev xav tau no tseem nruj. Muaj cov kev cai ntawm qhov tuab ntawm ntug, lub kaum sab xis thiab qhov sib txawv ntawm qhov sib txawv, thiab muaj ntau qhov ntau thiab tsawg dua qhov ntev ntawm cov yeeb nkab fittings. Qhov saum npoo zoo thiab cov khoom siv kho tshuab ntawm lub luj tshib yog qhov zoo ib yam li cov yeeb nkab. Rau qhov yooj yim ntawm vuam, cov khoom siv hlau yuav tsum zoo ib yam li cov yeeb nkab txuas.

1. Txij li feem ntau ntawm cov yeeb nkab fittings yog siv rau vuam, txhawm rau txhim kho qhov vuam zoo, qhov kawg tau hloov mus rau hauv grooves, nrog rau qee lub kaum ntse ntse thiab ib qho ntug. Qhov kev xav tau no tseem nruj. Muaj cov kev cai ntawm qhov tuab ntawm ntug, lub kaum sab xis thiab qhov sib txawv. Qhov saum npoo zoo thiab cov khoom siv kho tshuab yog qhov pib zoo ib yam li cov kav dej. Rau qhov yooj yim ntawm vuam, qib steel ntawm cov yeeb nkab fittings thiab cov kav dej txuas yog tib yam.

1. Ntawd yog, tag nrho cov yeeb nkab fittings yuav tsum raug kho rau saum npoo, thiab cov hlau oxide nplai nyob rau sab hauv thiab sab nrauv yuav tsum tau txau los ntawm kev txhaj tshuaj peening, thiab tom qab ntawd coated nrog anti-corrosion xim. Qhov no yog rau cov kev xav tau export. Ntxiv mus, nyob rau hauv Suav teb, nws kuj yog los pab txhawb kev thauj mus los thiab tiv thaiv corrosion thiab oxidation.

1. Ntawd yog, cov kev xav tau ntawm kev ntim khoom. Rau cov yeeb nkab me me, xws li xa tawm, cov thawv ntoo yuav tsum tau ua, txog 1 cubic meter. Nws tau teev tseg tias tus naj npawb ntawm lub luj tshib hauv cov thawv no tuaj yeem tsis pub dhau 1 tuj. Tus qauv tso cai rau suits, uas yog, loj poob thiab me me, tab sis tag nrho qhov hnyav yuav tsis pub tshaj 1 tuj. Rau cov khoom loj y, ib pob yuav tsum tau ua.
