Ingabe amapayipi omlilo angenziwa ngezifiso ubude nobubanzi obuthile?
Yebo, amapayipi omlilo angafanelana nobude nobubanzi obuthile, kusukela ku-DN25 kuya ku-DN100. Ngisika amapayipi abe ngobude obufunekayo futhi ngilungise amadayamitha ukuze ngihlangabezane nezidingo zokugeleza nengcindezi yezinhlelo zokusebenza ezihlukahlukene.
Yiziphi izinto ezivame ukusetshenziselwa amapayipi omlilo?
Amapayipi omlilo avame ukwenziwa kusukaI-PVC, PU, noma EPDM. Into ngayinye inikeza izinzuzo ezihlukile. Isibonelo, i-PVC ayisindi, i-PU ayizwani nemihuzuko, futhi i-EPDM idlula ukushisa nokumelana namakhemikhali. Ngikhetha izinto ezisekelwe ezidingweni zemvelo nezokusebenza.
Ngiqinisekisa kanjani ukuhambisana phakathi kwamapayipi nama-couplings?
Ukuze ngiqinisekise ukuhambisana, ngibheka uhlobo lokuhlanganisa, usayizi wentambo, namazinga wendawo okuvikela umlilo. Ukufanisa lezi zicaciso kuqinisekisa ukuxhumana okuphephile futhi kuvimbela ukubambezeleka phakathi nemisebenzi ebalulekile.
Kungani amapayipi omlilo etholakala ngemibala ehlukene?
Amapayipi omlilo afika amhlophe noma abomvu ukukhombisa ukusetshenziswa kwawo. Amapayipi amhlophe ngokuvamile awezinjongo zezimboni noma zezolimo, kuyilapho amapayipi abomvu eyindinganiso yokucisha umlilo. Ngihlale ngiqondanisa umbala nohlelo lokusebenza ukuze ngigweme ukudideka ngesikhathi sezimo eziphuthumayo.
