A: Ipayipi yensimbiivimbela ukusabalala komlilo kangcono kakhulu kunepayipi lepulasitiki ngoba i-iron ayishi.Ngeke iwubambe umlilo noma ishe, ishiye imbobo lapho intuthu namalangabi angangena khona esakhiweni.Ngakolunye uhlangothi, ipayipi elivuthayo elifana ne-PVC ne-ABS, lingasha liphele, Ukumisa umlilo epayipini elivuthayo kuwumsebenzi omningi, futhi izinto zokwakha ziyabiza, kodwa ukumisa umlilo wepayipi lensimbi, ipayipi elingashi, kulula ukulifaka. futhi engabizi.
B: Enye yezimfanelo ezihlaba umxhwele kakhulu zepayipi lensimbi ekhonjiwe ukuhlala kwayo isikhathi eside.Ngenxa yokuthi ipayipi lepulasitiki lifakwe ngobuningi kusukela ekuqaleni kwawo-1970, impilo yalo yesevisi ayikanqunywa.Kodwa-ke, ipayipi yensimbi ekhonjiwe isetshenziswe kusukela ngawo-1500 eYurophu.Eqinisweni, amapayipi ensimbi asakaza imithombo yaseVersailles eFrance iminyaka engaphezu kuka-300.
C: Kokubili ipayipi lensimbi elisansimbi kanye nepayipi lepulasitiki kungaba sengozini yezinto ezigqwalayo.Ipayipi le-cast iron lingaphansi kokugqwala lapho izinga le-pH ngaphakathi kwepayipi lehla libe ngaphansi kuka-4.3 ubude besikhathi, kodwa asikho isifunda samapayipi endle eMelika esivumela noma yini ene-pH engaphansi kuka-5 ukuthi ilahlwe ohlelweni lwaso lokuqoqa indle.I-5% kuphela yenhlabathi yenhlabathi eMelika egqwala ukugaywa insimbi, futhi uma ifakwe kuleyo nhlabathi, ipayipi lensimbi elicijile lingavikelwa kalula futhi ngokungabizi.Ngakolunye uhlangothi, ipayipi lepulasitiki lisengozini yama-asidi amaningi nezincibilikisi futhi lingonakaliswa yimikhiqizo ye-petroleum.Ukwengeza, uketshezi olushisayo olungaphezu kwamadigri angu-160 lungalimaza izinhlelo zamapayipi e-PVC noma ze-ABS, kodwa akubangeli inkinga ngepayipi lensimbi ekhonjiwe.
