Welded Pob Qus Ntawm Cov Qauv Hlau Siv
Welded Pob Qus Ntawm Cov Qauv Hlau Siv
Tsawg dua cov pob qij txha, tsis txhob muaj ob txoj kev, peb-txoj kev sib tshuam nyob rau hauv txoj kev vuam sib txawv ntawm kev zawj xim thiab qhov loj me. Weld txoj hauj lwm kom tsis txhob muaj kev ntxhov siab siab; Rau kev siv vuam kev ua haujlwm, zam kev ua haujlwm overhead chaw vuam; txo tus naj npawb thiab loj ntawm weld; Kev npaj ntawm Weld hauv cov tswv cuab ntu ntawm ib feem ntawm lub taub hau neutral; Tsim kev tsim khoom, yuav tsum tau ua lub luag haujlwm ntawm cov qauv hlau tsim kev tsim qauv lossis kev pom zoo los ntawm thawj chav tsim qauv.
Thaum welded sib txuas, phab ntsa thickness ntawm 5 mm lossis ntau dua cov kav hlau, lippi yuav tsum nyob rau ntawm cov npoo muaj 1 ~ 2 hli tuab blunt ntug. Groove muaj nyob rau hauv cov tshuab lossis roj ua cov txheej txheem vuam, vuam ua cov seem yuav tsum tau muab tshem tawm, tsis sib xws yuav tsum tau xuab zeb zoo. Ob qho kev txheeb xyuas cov xim Axial Axial, Thaum Phab Ntsa Thickness 3 ~ 5 hli 1 ~ 1.5 hli; yeeb nkab phab ntsa thickness 5 ~ 9 hli rau 1.5 ~ 2 hli; Yeeb Nkab Phab Ntsa Thickness 9 Hli rau 2 ~ 3 hli. Counterpart ntawm Ncaj Seam Welded Steel Vuam, Ntev Ntev Weld yuav tsum staggered tsis tsawg tshaj li 100 hli. Thaum txais yuav cov flange txuas, flange yuav tsum txiav mus rau yeeb nkab nruab nrab, kev siv ntawm ob tus flanges yuav tsum tau sib piv rau ib leeg. Lub thickness ntawm flange gasket tsim muab, asbestos tshuab ntxhua khaub ncaws lossis ntau dua 3 hli, 3 ~ 5 hli tuab ntawm cov roj hmab gasket. Sab hauv lub tshuab nqus tsev ntawm cov tshuab ntxhua khaub ncaws yuav tsum haum nrog sab hauv ntawm cov yeeb nkab sab nraud lub cheeb sab nraud lub cheeb sab nraud lub cheeb sab nraud. Flange interface yuav tsis raug faus rau hauv av, ying ua rau hauv lub manhole lossis hauv qhov xwm txheej, thaum muaj kev ntsuas tsim nyog.
