- Ngo-2020, amapayipi omlilo alawula izindawo ezingaphezu kuka-70% zomlilo emahlathini e-US, afinyelela izinga lempumelelo elingu-95%. Kodwa-ke, ukusetshenziswa nokugcinwa okungafanele kuseyinselele.
- Imithethonqubo eqinile yokuphepha komlilo kanye nezindinganiso ze-NFPA ziqokomisa isidingo sobuchwepheshe bobuchwepheshe ekuguqulweni okuyinkimbinkimbi.
Ochwepheshe bokubonisana baqinisekisa ukuthobela imithetho, ukuphepha, kanye nokusebenza kahle kakhulu ezimweni ezibucayi.
Imibuzo Evame Ukubuzwa
Iyini ingcindezi yokusebenza ejwayelekile yamapayipi omlilo?
Ingcindezi yokusebenza ejwayelekile yamapayipi omlilo ivame ukusuka kumabha ayi-8 kuya kumabha ayi-18. Ngihlala ngincoma ukuqinisekisa izidingo zengcindezi ngokusekelwe kuhlelo lokusebenza oluhlosiwe ukuqinisekisa ukuphepha nokusebenza kahle.
Ingabe amapayipi omlilo angenziwa ngokwezifiso ngobude nobubanzi obuthile?
Yebo, amapayipi omlilo angalungiswa ngobude nobubanzi obuthile, kusukela ku-DN25 kuya ku-DN100. Ngisika amapayipi ngobude obufunwayo bese ngilungisa ububanzi ukuze kuhlangatshezwane nezidingo zokugeleza nokucindezela kwezicelo ezahlukahlukene.
Yiziphi izinto ezivame ukusetshenziswa kumapayipi omlilo?
Amapayipi omlilo avame ukwenziwaI-PVC, PU, noma EPDM. Izinto ngazinye zinikeza izinzuzo ezihlukile. Isibonelo, i-PVC ilula, i-PU imelana nokuhuzuka, kanti i-EPDM idlula zonke ekumelaneni nokushisa namakhemikhali. Ngikhetha izinto ngokusekelwe ezidingweni zemvelo nezokusebenza.
Ngingaqinisekisa kanjani ukuthi amapayipi nama-coupling ayahambisana?
Ukuze ngiqinisekise ukuhambisana, ngihlola uhlobo lokuxhuma, usayizi wentambo, kanye nezindinganiso zokuvikela umlilo zendawo. Ukuhambisana nalezi zici kuqinisekisa uxhumano oluphephile futhi kuvimbela ukubambezeleka ngesikhathi semisebenzi ebalulekile.
Kungani amapayipi omlilo etholakala ngemibala ehlukene?
Amapayipi omlilo afika ngombala omhlophe noma obomvu ukukhombisa ukusetshenziswa kwawo. Amapayipi amhlophe ngokuvamile enzelwe izimboni noma ezolimo, kanti amapayipi abomvu ajwayelekile ekulweni nomlilo. Ngihlala ngivumelanisa umbala nohlelo lokusebenza ukuze ngigweme ukudideka ngesikhathi sezimo eziphuthumayo.
