Uyazi ukuthi isikhathi eside kangakanani impilo yepayipi lensimbi evamile?

Ukuze kuthuthukiswe ukumelana nokugqwala, ipayipi lensimbi elijwayelekile (ipayipi elimnyama) liyakhanyiswa. Ipayipi lensimbi eliphehliwe lihlukaniswe laba 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 lokucwenga 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.
