Nokuba yinkqubo yokubonelela ngamanzi kamasipala okanye inethiwekhi yokusasaza igesi, imibhobho yethu inokumelana neengqolowa zokusetyenziswa kwemihla ngemihla ngelixa igcina ukusebenza kakuhle. Ildid kunyeumbhobho womthungoUkhetho lubonelela ngokuguquguquka kwisicelo, ukuvumela izisombululo zokufezekiswa ukufezekisa iimfuno ezithile zeprojekthi.

FAQ

I-Q1. Yeyiphi impahla esenziwa ngumbhobho wamanzi ophambili olwenziwe?

Amanzi amachiza ahlala enziwa ngezinto ezihlala ezomeleleyo ezinje ngentsimbi, i-PVC kunye ne-HDDE. Ukukhetha kwezinto kuxhomekeke kwiseti yesicelo kunye neemeko zokusingqongileyo.

Q2. Yeyiphi imibhobho ye-welday kunye nemibhobho ye-spiral seam?

Imibhobho ye-Welding yenziwa ngokujoyina imiphetho emibini yombhobho kunye, enomxholo onamandla nobonwabisayo. Imibhobho ye-Spiral Seam yenziwa ngokuqengqesha umtya wensimbi we-tube, onobutshaba obukhulu bokuyilwa kunye nokusetyenziswa.

Q3. Ndiyikhetha njani imibhobho yasekunene yeprojekthi yam?

Cinga ngezinto ezinje ngohlobo lolwelo oludluliselwa, iimfuno zoxinzelelo, kunye neemeko zokusingqongileyo. Ukubonisana nengcali kunokunceda ukuqinisekisa ukuba ukhetha eyona tyhunga ilungileyo kwiimfuno zakho.
