Ipayipi eliyindilinga elikhanyiswe ngamapayipi elishiselwe

Amapayipi ensimbi enziwe ngensimbi ahlukaniswe abe izinhlobo ezimbili: i-hot-dip galvanizing kanye ne-electro-galvanizing.I-hot-dip galvanizing layer iwugqinsi, izindleko ze-electro-galvanizing ziphansi, futhi indawo engaphezulu ayibushelelezi kakhulu.Ipayipi elishiselwe elifutha umoya-mpilo: lisetshenziselwa ukwenza insimbi amapayipi afutha umoya-mpilo, ngokuvamile amapayipi ensimbi anobubanzi obuncane, anezici eziyisishiyagalombili ezisuka ku-3/8 kuya ku-2 amayintshi.Sebenzisa i-8, 10, 15, 20 noma Yenziwe nge-strip yensimbi engu-195-Q235, ukuze kuvinjwe ukugqwala, kuyadingeka ukwenza ukwelashwa kwe-aluminizing.

Ipayipi elishiselwe i-hot-dip galvanized ukwenza insimbi encibilikisiwe isabelane ne-iron matrix ukukhiqiza ungqimba lwengxubevange, ukuze i-matrix kanye nokunamathela kuhlanganiswe.I-hot-dip galvanizing iwukuba kuqala uvuse ipayipi lensimbi.Ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokukhetha, ihlanzwa ethangini nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma isixazululo esinamanzi esixubile se-ammonium chloride ne-zinc chloride, bese sithunyelwa ithangi lokucwilisa elishisayo.I-hot-dip galvanizing inezinzuzo zokuhlanganisa iyunifomu, ukunamathela okuqinile nempilo ende yesevisi.

I-Cold galvanizing i-electro-galvanizing, kanti inani lokugalela lincane kakhulu, liyi-10-50g/m2 kuphela, futhi ukumelana nokugqwala kwalo kubi kakhulu kunamapayipi afaka uthayela adiphu ashisayo.
