Umbhobho ojikelezileyo we-Galvanized welded pipe

Imibhobho yentsimbi egayiweyo yahlulwe yaba ziintlobo ezimbini: i-hot-dip galvanizing kunye ne-electro-galvanizing. Umaleko we-hot-dip galvanizing utyebile, ixabiso le-electro-galvanizing liphantsi, kwaye umphezulu awugudi kakhulu. Umbhobho we-oksijini ovuthela ioksijini: osetyenziselwa imibhobho yokwenza ioksijini, ngokubanzi imibhobho yentsimbi evuthela ioksijini enobubanzi obuncinci, eneempawu ezisibhozo eziqala kwi-3/8 ukuya kwi-2 intshi. Sebenzisa i-8, 10, 15, 20 okanye Yenziwe nge-195-Q235 steel strip, ukuze kuthintelwe ukugqwala, kuyimfuneko ukwenza unyango lwe-aluminizing.

Umbhobho odibeneyo we-hot-dip galvanizing kukwenza isinyithi esinyibilikisiweyo sisebenze kunye ne-iron matrix ukuvelisa umaleko we-alloy, ukuze i-matrix kunye ne-coating zidityaniswe. I-hot-dip galvanizing kukuqala ngokucola umbhobho wentsimbi. Ukuze kususwe i-iron oxide kumphezulu wombhobho wentsimbi, emva kokucola, icocwa etankini nge-ammonium chloride okanye isisombululo samanzi esixutyiweyo se-ammonium chloride kunye ne-zinc chloride, ize ithunyelwe kwi-In the hot dip plating tank. I-hot-dip galvanizing ineengenelo zokucola okufanayo, ukunamathela okuqinileyo kunye nobomi obude benkonzo.

Ukufaka i-galvanizing ebandayo kukusebenzisa i-electro-galvanizing, kwaye ubungakanani be-galvanizing buncinci kakhulu, yi-10-50g/m2 kuphela, kwaye ukumelana kwayo nokugqwala kubi kakhulu kunokweepayipi ze-galvaning ezitshixwayo ngobushushu.
