qhov sib txawv ntawm cov yeeb nkab steel ua ntej thiab cov yeeb nkab steel kub-galvanized
Cov yeeb nkab galvanized kub yog cov yeeb nkab dub ntuj tom qab tsim khoom immersed hauv cov tshuaj plating. Qhov tuab ntawm cov txheej zinc raug cuam tshuam los ntawm ntau yam, suav nrog qhov chaw ntawm cov hlau, lub sijhawm nws siv los immersed cov hlau hauv da dej, cov khoom sib xyaw ntawm cov hlau,...Nyeem ntxiv -
Cov hlau carbon
Cov hlau carbon yog cov hlau uas muaj cov pa roj carbon txij li ntawm 0.05 txog 2.1 feem pua ntawm qhov hnyav. Cov hlau mos (hlau muaj feem pua me me ntawm cov pa roj carbon, muaj zog thiab tawv tab sis tsis yooj yim tempered), tseem hu ua cov hlau carbon dawb thiab cov hlau carbon qis, tam sim no yog hom hlau feem ntau vim nws cov khoom...Nyeem ntxiv -
ERW, LSAW Cov Yeeb Nkab Hlau
Cov yeeb nkab hlau ncaj yog cov yeeb nkab hlau uas nws cov xov sib txuas sib luag rau qhov ntev ntawm cov yeeb nkab hlau. Cov txheej txheem tsim cov yeeb nkab hlau ncaj yog yooj yim, nrog rau kev ua haujlwm siab, tus nqi qis thiab kev txhim kho sai. Lub zog ntawm cov yeeb nkab vuam sib txuas feem ntau yog siab ...Nyeem ntxiv -
ERW yog dab tsi
Kev vuam hluav taws xob tiv taus (ERW) yog ib qho txheej txheem vuam uas cov khoom hlau uas sib cuag tau sib txuas tas mus li los ntawm kev ua kom sov nrog hluav taws xob, ua rau cov hlau ntawm qhov sib koom ua ke yaj. Kev vuam hluav taws xob tiv taus yog siv dav, piv txwv li, hauv kev tsim cov yeeb nkab hlau.Nyeem ntxiv -
SSAW Cov Yeeb Nkab Hlau vs. LSAW Cov Yeeb Nkab Hlau
LSAW Yeeb Nkab (Longitudinal Submerged Arc-Welding Pipe), tseem hu ua SAWL yeeb nkab. Nws yog siv cov hlau phaj ua cov khoom siv raw, pwm nws los ntawm lub tshuab molding, tom qab ntawd ua ob sab submerged arc vuam. Los ntawm cov txheej txheem no, LSAW yeeb nkab hlau yuav tau txais kev ua haujlwm zoo heev, kev sib txuas ruaj khov, kev sib xws, ...Nyeem ntxiv -
Cov Yeeb Nkab Hlau Galvanized vs. Cov Yeeb Nkab Hlau Dub
Cov yeeb nkab hlau galvanized muaj cov txheej zinc tiv thaiv uas pab tiv thaiv kev xeb, xeb, thiab kev sib sau ua ke ntawm cov khoom siv minerals, yog li ua rau cov yeeb nkab siv tau ntev dua. Cov yeeb nkab hlau galvanized feem ntau siv rau hauv cov kav dej. Cov yeeb nkab hlau dub muaj cov xim tsaus nti hlau-oxide txheej rau ntawm nws qhov nkag...Nyeem ntxiv
