Kev tshuaj xyuas ntawm cov txheej txheem txheej xim: Tshawb xyuas seb puas du thiab dawb ntawm burrs, seb puas muaj cov hlau sib tw tus neeg yuav tsum tau ua.
Kev txheeb xyuas cov txheej txheem txheej txheej ntawm cov tuab tuab: ua kom cov txheej txheej txheej txheej uas ua tau raws li cov neeg siv khoom tshwj xeeb.
Txoj kev ntsuas pinhole: Ua ib qhov kev xeem los kuaj xyuas cov pinholes hauv txheej.
Adhesion kuaj: Ua cov nplaum xeem raws li A thiab B ntawm CJ / T {0}}.
Khoov xeem: Txiav ib qho hnoos qeev kwv yees li 50 hli ntev los ntawm txhua txoj haujlwm ntawm cov yas-coated steel yeeb nkab hauv kev sim. Muab cov quav rau ntawm ob lub tiaj tiaj tus phiaj ntawm chav tsev kub thiab maj nrawm nws siv lub tshuab kuaj Tensile. Rau cov txheej txheem polyethylene, tswj qhov kev ncua deb ntawm ob daim phiaj los ua 2/3 ntawm cov quav me rau lub taub; Rau epoxy cob cov txheej txheej, tswj qhov kev ncua deb mus ua 4/5 ntawm cov quav ib qho hnoos qeev. Thaum lub sij hawm compression, xyuas kom meej tias Weld Seam Seam ntawm cov yas-txheej hlau yeeb nkab txuas mus rau compression. Tom qab feattening, saib lub puab txheej rau cov kab nrib pleb thiab tev. Rau cov yas-coated steel kav xaim nrog cov nominal ntau dua DN200, DNNES tuaj yeem siv hloov ua hloov.
Flattening Test: Ua ib qhov kev ntsuas dav dav ntawm cov yas-coated steel kav hlau nrog lub taub sab nraud ntau dua 50 hli. Qhov ntev ntawm cov yeeb nkab ntu yuav tsum yog (50 ± 10) hli. Tso cov zis nruab nrab ntawm ob lub tiaj tiaj tiaj ntawm (20 ± ntsaws nws ntawm lub taub hau siab kom txog thaum epoxy cob cov khaub hlab lossis 2/3 rau polyethylene txheej. Thaum lub sij hawm compression, xyuas kom meej tias kev siv Weld ntawm cov coated steel yeeb nkab txuas rau lub thauj khoom thov kev taw qhia. Tom qab ntsuas, tshawb xyuas cov txheej sab hauv kom tawg thiab tev. Yog tias tsis muaj xws li cov tsis xws luag, cov yeeb nkab tau pom tias tsim nyog. Rau cov yas-coated steel kav xaim nrog cov nominal ntau dua DN200, DNNES tuaj yeem siv hloov ua hloov.
Kev Ntsuas Yuam: Txiav ib qho hnoos qeev li ntawm 100 hli ntev los ntawm txhua txoj haujlwm ntawm cov yas-coated steel yeeb nkab hauv kev sim. Ua qhov kev cuam tshuam ntawm chav kub raws li teev nyob rau hauv daim duab hauv qab no, nrog Weld Seam ofe Rauv rov qab mus rau qhov cuam tshuam nto. Tom qab ntsuas, tshawb xyuas cov txheej sab hauv kom tawg thiab tev. Yog tias tsis muaj xws li cov tsis xws luag, cov yeeb nkab tau pom tias tsim nyog. Rau cov yas-coated steel kav xaim nrog cov nominal ntau dua DN200, DNNES tuaj yeem siv hloov ua hloov.
Kev ua tib zoo kev sim: Ua kev ntsuas kev nyiam huv raws li GB / T 17219.
Lub Tshuab Nqus Tsev: Qhov ntev ntawm cov yeeb nkab ntu yuav tsum yog (500 ± 50) mm. Thaiv cov inlet thiab qhov hluav taws xob uas siv cov kev ntsuas kom haum thiab maj mam nce cov inlet rau 660mm HG, tswj nws rau 1 feeb. Tom qab kuaj, tshawb xyuas cov txheej hauv cov txheej txheem sab hauv rau txhua qhov chaw nyob.
Kev ntsuam xyuas kub siab tiv thaiv, tsawg kub Xaus Kuaj, Kuaj Siab Siab, Kub Kev Ntsuas Dej Kub, thiab lwm yam.
