** 1. Dab tsi yog qhov nyuaj tshaj plaws rau weld ib nkab? **
Lub 6g txoj haujlwm yog thoob ntiaj teb tau suav tias yog txoj haujlwm nyuaj tshaj plaws rau vuam cov yeeb nkab. Hauv txoj haujlwm no, cov yeeb nkab yog tsau ntawm 45 -℃kaum sab xis thiab tsis tuaj yeem tig. Qhov no yuav tsum muaj cov welder kom ua txhua hom weld (tiaj, kab rov tav, ntsug, thiab overhead) hauv ib puag ncig ntawm cov yeeb nkab nruab ncig ntawm cov yeeb nkab nruab ncig ntawm cov yeeb nkab nruab nrab ntawm txoj hlab. Nws xav tau kev kawm tshwj xeeb, kev tswj hwm, thiab lub peev xwm los ua kom haum kev hloov kho rau lub ntiajteb txawj nqus weld ntawm daim ntaub weld. Dhau ib qho kev xeem vuam yog feem ntau yog qhov yuav tsum tau ua rau cov ntawv thov tseem ceeb thiab kev kub siab tshaj plaws.
** 2. Puas yog cov yeeb nkab tuaj yeem welded? **
Yog lawm, qee hom dej kav hlau tuaj yeem welded, tab sis nws tsis yog txoj kev txheem rau txhua cov ntaub ntawv. Hlau kav hlau kav hlau zoo li hlau (suav nrog cov hlau dub thiab galvanized) thiab tooj liab tuaj yeem welded. Txawm li cas los xij, vuam yog feem ntau siv rau loj {2} kev lag luam loj, ua lag luam, lossis cov kav dej loj dua li cov kav dej hauv tsev. Cov kev ceev faj tshwj xeeb yog xav tau; Piv txwv li, vuam galvanized steel tso tawm cov pa luam yeeb mob toxic, thiab tooj liab xav tau cov txheej txheem tshwj xeeb xws li Tig Vuam. Tsev neeg cov kav dej uas muaj ntau ntxiv siv cov lus, soldered, lossis xovxwm {5} haum rau kev ceev thiab tus nqi.
** 3. Qhov twg yog qhov zoo dua, seamless lossis welded yeeb nkab? **
Tsis muaj ib qho "zoo dua" kev xaiv; Cov kev xaiv yog nyob ntawm daim ntawv thov cov cai.
* ** SEAMLESS YEEB ** yog feem ntau muaj zog thiab txhim khu kev qha rau siab -}} kub, lossis cov ntawv thov tseem ceeb. Vim tias nws tsis muaj qhov thaiv Weld, nws yog inherently ntau zuj zus thiab tsis tshua muaj kev poob siab. Txawm li cas los xij, nws yog kim dua thiab muaj qhov loj tshaj txwv.
* ** Welded yeeb nkab ** yog tus nqi ntau dua -}}} Zoo thiab tau yooj yim nyob hauv lub diam loj dua. Niaj hnub tsim, tshwj xeeb tshaj yog cov hluav taws xob tiv thaiv vuam (ERW) cov txheej txheem uas muaj zog rau cov dej sib xyaw, cov qauv dej, thiab qis {{}} h siab} lub siab. Lub peev xwm muaj zog yog lub ntsej muag Weld ntawm nws tus kheej.
Hauv cov ntsiab lus, xaiv seamless rau qhov tseem ceeb, siab - siab pab. Xaiv welded rau tus nqi rau tus nqi - rhiab, tus qauv- qhov kev siv siab.
** 4. Yuav muab cov kav dej phwv dej poom? **
Yog lawm, tab sis tsis zoo ib yam li hlau. Pvc kav tsis yog welded siv cua sov thiab ib tug pas nrig ua kom zoo li hlau los yog txhuas. Hloov chaw, lawv tau koom nrog siv cov txheej txheem hu li ** cov kuab tshuaj vuam ** lossis ** Cementing **. Cov kuab tshuaj tshwj xeeb tshaj plaws yog thov kom ib ntus yaj cov txheej ntawm ob sab ntawm lub PVC. Thaum cov ntawv tau thawb ua ke, lub pvc molecules fuse thiab cov kuab tshuaj yaj, tsim kom muaj kev sib tw ruaj khov uas yog muaj zog npaum li cov yeeb nkab nws tus kheej.
** 5. Dab tsi yog qhov nyuaj tshaj plaws rau weld? **
Cov yeeb nkab nyuaj tshaj plaws rau Weld yog kev sib xyaw ntawm cov khoom nyuaj hauv txoj haujlwm nyuaj tshaj plaws. Thaum lub sijhawm 6G yog qhov nyuaj tshaj plaws, cov khoom siv heev ua rau muaj kev nyuaj. Yog li ntawd, cov kav dej nyuaj tshaj plaws rau Weld feem ntau:
* ** Cov hlau tsis sib xws: ** VUAM ob cov hlau sib txawv (piv txwv li cov hlau sib txawv
* ** High {-}} Cov ntaub ntawv ua tau los ntawm cov ntaub ntawv zoo li chrome- moly hlau, thiab inconel yog qhov nyuaj heev. Lawv yuav tsum tau tswj kom puas tsuaj ntawm tshav kub, thiab feem ntau ua ntej ua ntej thiab tswj hwm}} Cov cua sov- cov khoom siv cua sov}} Cov khoom siv cua sov}
