Mhlawumbe uyazibuza ukuthi ungakhetha kanjani uhlobo olufanele lwepayipi lensimbi kuphrojekthi yakho njengoba kunezinhlobo ezahlukene zamapayipi ensimbi ozikhethele emakethe. Ukwenza ukukhetha kwephrojekthi phakathi kwezinhlobo ezahlukene zepayipi lensimbi noma ishubhu kubonakala kuhlale kuyindaba yekhanda phakathi kwabasebenzisi abaningi bokugcina ekuphileni.
Emakethe yensimbi, ngokuvamile singathola izigaba ezimbili ezinkulu zamapayipi ensimbi: ipayipi elishiselwe kanye nepayipi elingenamthungo. Ngokuvamile, kunamakhasimende amaningi asibuza mayelana nendlela yokukhetha phakathi kwalezi zinhlobo ezimbili zamapayipi. Ngokusobala, umehluko endleleni yokukhiqiza eyisisekelo uvela emagameni abo. Ipayipi elingenamthungo liyakhishwa futhi lidonswe ku-billet kuyilapho ipayipi elishiselwe likhiqizwa emgqeni owakhiwe futhi washiselwa ukukhiqiza ishubhu. Ngokuvamile, kunomehluko emananini wepayipi lensimbi phakathi kwalezi zinhlobo ezimbili zamapayipi ensimbi ngenxa yezindlela ezihlukene zokukhiqiza emshinini wokugaya. Ngakolunye uhlangothi, nakuba ingcindezi yokusebenza yepayipi elishiselwe ingaphansi ngo-20% kunaleyo yepayipi elingenamthungo elifanayo, ukucindezela kokusebenza akuyona into enqumayo yokukhetha ipayipi elingenamthungo phezu kwepayipi elishiselwe lemigqa yesampula yokuhlaziya. Umehluko ekungcoleni okungenzeka, okunciphisa ukumelana nokugqwala kwepayipi eliqediwe, yingakho ipayipi elingenasici licacisiwe.
Ngaphezu kwalokho, ngobuchwepheshe obuhlukene bokucubungula, kuzoba nezindleko ezihlukene zomkhiqizo. Lokho kungabonakala ngokucacile emalini ehlukene yamapayipi amapayipi ensimbi. Ngenxa yezindleko eziphakeme, ipayipi lensimbi elicwilisiwe elishisayo linenani eliphakeme kunalelo lepayipi lensimbi elakhiwe nge-electro-galvanized. Ngakolunye uhlangothi, ipayipi elishisayo elicwilisiwe lensimbi linohlu olubanzi lwezinhlelo zokusebenza kunepayipi lensimbi elenziwe nge-electro-galvanized. Namuhla, ipayipi lensimbi elenziwe nge-electro-galvanized seliphumile emakethe yensimbi ngenxa yokuvinjelwa kukazwelonke ngezinjongo zangempela. Ngaphezu kwalokho, ngokombono wochwepheshe, kukhona umehluko omkhulu phakathi kwamapayipi amabili kusukela ekubukeni. Izindlela ezimbili ezihlukene zokucubungula ngeke zithinte kuphela isicelo esithile ekusetshenzisweni okungokoqobo, kodwa futhi zizobangela ukubonakala okuhlukile kwamapayipi ensimbi. Njengoba cishe bonke abakhiqizi bamapayipi ensimbi bazi, ipayipi lensimbi elicwilisiwe elishisayo linongqimba lwezinki olushubile kunepayipi elenziwe nge-electro-galvanized. Uma nje sibheka ngokucophelela, kulula ukwenza umehluko phakathi kwalezi zinhlobo ezimbili zamapayipi.
