1. Bheka ukuthi i-lumen ijwayelekile yini nokuthi ukushuba kodonga kuyafana.Umgodi ongaphakathi kanye nomphetho wangaphandle wepayipi lensimbi yensimbi ye-PVC yekhwalithi enhle iyindilinga evamile?Udonga lwamapayipi e-annular lusatshalaliswa ngokulinganayo.Thatha ipayipi lensimbi le-PVC elinobubanzi obungaphakathi obungu-89mm nobukhulu bodonga obungu-7mm njengesibonelo?Ingxenye ewugqinsi yodonga lwamapayipi enekhwalithi ephansi ingafinyelela ku-7.5mm?Ingxenye ye-thinnest ingu-5.5mm kuphela?Ibangela ukuthi ipayipi lensimbi le-PVC liqhume noma liwohloke?Kuthinta ukusetshenziswa okuvamile.
2. Bheka ukuthi akhona yini amabhamuza omoya noma ezinye izinto ezibonakalayo odongeni lwepayipi lensimbi le-PVC?Ingabe ayinambala futhi isobala.Udonga lwepayipi yensimbi yekhwalithi ephezulu ye-PVC icacile?Akukho ukungcola.Umbala ophuzi wepayipi lensimbi le-PVC elingasebenzi kahle ungase ubangelwe ukubola, ukuguga, noma isitoreji esingafanele sesikhathi eside ngenxa yokuphatha okungalungile phakathi nenqubo yokukhiqiza.
3. Ngaphandle kwephunga elincane lepulasitiki, ipayipi lensimbi lekhwalithi ephezulu le-PVC alinalo iphunga lanoma yimiphi eminye imikhiqizo ye-petrochemical.Futhi ipayipi lensimbi eliphansi linephunga elimnandi nelibukhali likadizili?Ikakhulukazi ehlobo elishisayo?Abantu abakwazi ukusondela.
4. Izindonga zangaphakathi nezingaphandle zamapayipi ensimbi ekhwalithi ephezulu ye-PVC abushelelezi futhi azizwa emuhle, kuyilapho amapayipi ekhwalithi ephansi enokhahlo uma kuqhathaniswa.
5. Lapho ukala ukujiya kodonga?Iziphetho ezimbili zepayipi lensimbi yensimbi ye-PVC kufanele zinqunywe?Ipayipi eliphakathi kufanele likhethwe njengesampula yokuhlola?Ukuvimbela abakhiqizi abathile abangenangqondo ukuba benze ingxabano emikhawulweni yomibili yepayipi?
6. Sika amasentimitha ambalwa ocingo lwensimbi kuzo zombili iziphetho zepayipi lensimbi ye-PVC?Songa intambo yensimbi ngokuphindaphindiwe?Hlola amandla nokuqina kwentambo yensimbi.Ucingo lwensimbi olusezingeni eliphansi luzophuka ngemva kokugoqa okukodwa noma okubili?Intambo yensimbi yepayipi yensimbi yekhwalithi ephezulu ye-PVC idinga amathuluzi akhethekile ukuze anqunywe.Ikhwalithi yocingo lwensimbi inquma ikhwalithi yepayipi yonke?Ipayipi lensimbi yensimbi ye-PVC elinezinkinga zekhwalithi ezibangelwa ucingo lwensimbi lithambekele ekuguquguqukeni okungenakuhlehliswa.
