Ehlotyeni, kuya kubakho iimini ezininzi zemvula. Ngaloo ndlela ukukhupha amanzi kuba ngumsebenzi obalulekileyo. Ngokubanzi, ipayipi yePVC kunye nepayipi yesinyithi zombini zilungile ekukhupheni amanzi. Nangona kunjalo, abanye abantu bacinga ukuba ipayipi yesinyithi inzima kakhulu kunepayipi yePVC. Kuba ngokoluvo lwabo, isinyithi sinzima kuneplastiki. Kodwa eneneni, asinjalo kanye. Ngaphandle kwezinto eziphathekayo, ezinye izinto ezininzi zichaphazela ubunzima, njengobukhulu bodonga.
Ingaba ipayipi yentsimbi erhabaxa inzima?
Enyanisweni, ubungakanani obahlukeneyo, ubukhulu kunye nezinye iinkcukacha zibangela ubunzima obahlukeneyo. Umzekelo, ubunzima bepayipi yesinyithi ye-DN50 kunye ne-0.25mm ubukhulu malunga ne-0.45kg/m. Ngelixa i-0.55kg/m ye-DN60 enobukhulu obufanayo. Ngaphandle koko, ubunzima bepayipi ye-DN50 kunye ne-0.28mm ubukhulu yi-0.5kg/m. Ezi ntlobo zintathu nazo zezona zisetyenziswa kakhulu.
Indlela yokuvavanya ipayipi yentsimbi ebotshelelweyo yeprestress
Olu vavanyo lujolise kakhulu ekujongeni inkangeleko, ububanzi, ukuqina kunye nokusebenza kokugoba. Kukwakho nomgangatho we-JG 225-2007 oqhelekileyo. Ngaphandle kwepayipi ngokwayo, umgangatho ukwachaza ulwahlulo, imfuneko, indlela yokuvavanya, ukupakisha kunye nokudlulisa. Ngokuphathelele izinto, kufuneka izinto zibe yi-zinc coat okanye i-mild steel.
Kwelinye icala, gcina umphezulu wepayipi yesinyithi ebotshelelweyo ucocekile. Ngaphandle koko, akufuneki kubekho ioyile, umhlwa kunye nomngxuma kumphezulu wangaphakathi nowangaphandle. Oku kuphela esinokuthi kuqhelekile. Okubaluleke ngakumbi, akuyi kubakho ngxaki yomgangatho okanye yokugcina izinto kwixesha elizayo. Ngokubanzi, kufuneka uyijonge ngokungqongqo emva kwemveliso. Kuphela ziimveliso ezifanelekileyo ezinokuthengiswa.
Namhlanje sifunde ubunzima kunye novavanyo lwepayipi yesinyithi erhabaxa. Ngaba ufuna ukufunda okungakumbi? Landela nje i-OrientFlex. Singumvelisi ochwephesha wazo zonke iintlobo zeepayipi. Ngaphandle kweepayipi ngokwazo, sikunika ezona zisombululo zibalaseleyo. Ngoku sifuna iqabane lehlabathi, ngoko ke ukuba unomdla, nxibelelana nathi ngoku.
