"DN100 tee" tsis yog cov ntaub ntawv txaus rau kev txiav txim ntau lawm. Ua ntej Haihao npaj cov khoom, qhov kev nug yuav tsum txheeb xyuas tus qauv seem, tee configuration, phab ntsa thickness, cov ntaub ntawv qib, kom muaj nuj nqis, thiab ib qhov project - tshwj xeeb yuav tsum tau. Lub pob tw-weld tee yuav tsum tau tshuaj xyuas ua ke nrog rau daim ntawv thov thiab kev txiav txim yuav tsum tau ua.
Tus qauv los ua ntej. ASME, GOST, thiab DIN tsis siv ib qho kev sib txawv, yog li cov qauv xaiv yuav tsum tau sau ncaj qha rau ntawm kev nug. Tom ntej no, hais seb lub tee yog sib npaug los yog txo. Ib tug txo tee xav tau ob qho tib si khiav loj thiab ceg loj. Lub pob tw -weld tee tuaj yeem teev tau raws li qhov xav tau ntawm qhov project.
Phab ntsa thickness tsuas yog ib qho tseem ceeb vim hais tias cov fittings xaus yuav tsum phim cov yeeb nkab txuas. Yog tias qhov project siv lub sijhawm tshwj xeeb, sau lub sijhawm kom meej ua ke nrog lub npe kab.
Cov khoom yuav tsum tau muab raws li qib tshwj xeeb. A234 WPB, 304, 304L, 316, thiab 316L yog cov piv txwv ntawm cov lus piav qhia meej. Alloy steel yuav tsum tau txheeb xyuas los ntawm qib thiab. Kev xaiv lub pob tw-weld tee yuav tsum muaj kev cuam tshuam txog kev ua haujlwm thiab kev npaj ua haujlwm.
Tom qab ntawd, ntxiv cov txheej txheem saum npoo uas xav tau. Cov pa roj carbon steel tej zaum yuav liab qab, pleev xim rau, tiv thaiv xeb- tiv thaiv roj, coated, los yog kub-dip galvanized. Stainless hlau tej zaum yuav xav tau acid ntxuav los yog sandblasting.
Ua kom tiav cov lus nug nrog kom muaj nuj nqis, ntim khoom xav tau, cov ntsiab lus tshuaj xyuas, thiab ib qho duab kos- tswj cov ntsiab lus. Ib qho kev ua tiav ntawm cov ntaub ntawv ua kom yooj yim rau kev yuav khoom thiab pab pawg tsim khoom ua haujlwm los ntawm tib qhov yuav tsum tau ua yam tsis muaj kev rov hais dua, thiab nws txo qis kev hloov kho uas tsis tuaj yeem ua ntej txiav pib. Lub pob tw -weld tee tuaj yeem lees paub nrog qhov yuav tsum tau muaj qhov ntev thiab cov ntaub ntawv thov.
Qhov no yog qhov tshwj xeeb tshaj yog thaum ib daim ntawv yuav khoom muaj ob peb ceg ntoo.
