Tom qab seamless steel yeeb nkab yog tsim, nws dhau los ua cov txheej txheem acid pickling, ua raws li kev kho mob galvanizing raws li cov neeg siv khoom xav tau. Feem ntau muaj peb hom kev galvanizing: dai galvanizing, cua tshuab galvanizing, thiab galvanized sawb. Hanging galvanizing rau seamless steel kav ua tiav qhov siab tshaj plaws zinc txheej hnyav, tshaj 500g ib square meter. Cua tshuab galvanizing ua tiav ib puag ncig 300g ib square meter, thaum galvanized sawb welded kav, feem ntau siv tab sis nrog tsawg kawg ntawm zinc txheej, muaj zinc txheej hnyav ntawm tsuas yog 60-150g ib square meter. Tsuas yog tom qab seamless steel yeeb nkab tau raug galvanized tuaj yeem pib xov txiav. Cov txheej txheem no yog ua los ntawm cov kws lathes tshwj xeeb, nrog rau cov kev cai nruj rau taper, suab, thiab xov hom. Cov qauv sib txawv, suav nrog Asmeskas, Askiv, thiab National Standards. Ob qhov kawg ntawm seamless steel yeeb nkab undergo xov txiav, xov tu, thiab tshuaj xyuas ua ntej ib kawg yog haum nrog cov yeeb nkab txuas thiab lwm yam nrog lub hau yas los tiv thaiv cov xov. Galvanized steel kav nrog threaded xaus yog ntxiv categorized rau hauv American Standard thiab British Standard, nrog xov suav ntawm 8 los yog 10 hniav ib nti.
Kev tsim cov yeeb nkab txuas yog qhov tseem ceeb tshaj plaws thiab qhov tseem ceeb ntawm tag nrho cov khoom, vim tias lawv yog cov khoom siv uas ua rau lub siab tshaj plaws hauv tag nrho cov kab ke. Cov khoom zoo ntawm cov yeeb nkab txuas yuav tsum sib npaug los yog siab dua li ntawm seamless steel yeeb nkab nws tus kheej. Tom qab raug txiav los ntawm cov hlau puag ncig, cov yeeb nkab txuas txuas yog machined kom meej qhov ntev ntawm lub tshuab dhos, ua raws li xov txiav. Thaum kawg, cov xov thiab qhov ntev yog tshuaj xyuas kom muaj kev ruaj ntseg zoo.
Substandard kub-dip galvanized kauv steel kav feem ntau pom muaj qhov tshwm sim folding ntawm lawv qhov chaw. Qhov folding no yog tshwm sim los ntawm kev tsim cov folds thaum lub sij hawm tsim khoom, uas tshwm sim raws li longitudinal striations ntawm cov yeeb nkab. Qhov tshwm sim no tshwm sim thaum cov neeg tsim khoom lag luam tseem ceeb tshaj qhov ua tau zoo, ua rau muaj kev kub ntxhov ntau thaum lub sij hawm dov uas ua rau folding. Xws li cov kav dej tsis zoo no feem ntau ua rau tawg thaum siv, txo qis tag nrho lub zog ntawm cov hlau.
