Ukuze kuthuthukiswe ukumelana nokugqwala, ipayipi lensimbi elijwayelekile (ipayipi elimnyama) liyakhanyiswa.Ipayipi lensimbi eliphehliweihlukaniswe yaba idiphu elishisayo lashukumisa futhi likagesi lashukumisa izinhlobo ezimbili. I-hot dip galvanizing layer iwugqinsi futhi izindleko zokugalela ngogesi ziphansi, ngakho-ke kukhona amapayipi ensimbi. Kulezi zinsuku, ngokuthuthuka kwemboni, isidingo samapayipi ensimbi siyakhula.
Imikhiqizo yamapayipi ensimbi enamapayipi ensimbi eshisayo isetshenziswe emikhakheni eminingi, inzuzo ye-hot-dip galvanized ukuthi impilo yokulwa nokugqwala yinde. Isetshenziswa kabanzi embhoshongweni wamandla, umbhoshongo wokuxhumana, ujantshi, ukuvikelwa komgwaqo, isigxobo sokukhanya komgwaqo, izingxenye zasolwandle, izingxenye zesakhiwo sensimbi, izikhungo ezisekela iziteshi, imboni yokukhanya nokunye.
I-Hot dip galvanizing iwukuba kuqala ukucosha ipayipi lensimbi, ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokukhetha, nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma i-ammonium chloride ne-zinc chloride exutshwe nethangi lesisombululo samanzi sokuhlanza, bese ungena ethangini lokucwilisa elishisayo. I-hot dip galvanizing inezinzuzo zokuhlanganisa iyunifomu, ukunamathela okuqinile nempilo ende yesevisi. Iningi lezinqubo enyakatho zamukela inqubo yokugcwalisa i-zinc yepayipi lekhoyili eliqondile lebhande elinothayela.
Ukuphila kwamapayipi ensimbi okucwiliswa ashisayo ezindaweni ezihlukene akufani: iminyaka engu-13 ezindaweni zezimboni ezinzima, iminyaka engu-50 olwandle, iminyaka engu-104 ezindaweni ezingaphansi kwedolobha, kanye neminyaka engu-30 edolobheni.
