DN Ixabiso le-DN = ixabiso le-DE -0.5 * Ixabiso lobukhulu be-tube. Qaphela: Lo asingobubanzi bangaphandle okanye ububanzi bangaphakathi.

Amanzi, umbhobho wokuhambisa inyama yentsimbi (i-Galvaniated Piper okanye umbhobho wentsimbi engapheliyo), umbhobho wentsimbi yentsimbi, umbhobho wensimbi yentsimbi kunye ne-Polyviny ye-Polyvinyl Cyvintl (i-PVC), i-DN15 , DN50).

UDe (ububanzi bangaphandle) uthetha ububanzi bangaphandle bombhobho, i-PRP, i-PPR, iPolyproplene Pipe, iphawulwe i-DE, kwaye yonke into kufuneka iphawulwe njenge-De25 × 3 × 3 .

D ngokubanzi ibhekisa kububanzi obungaphakathi bombhobho.

D ngokubanzi ibhekisa kububanzi obungaphakathi bombhobho wekhonkrithi. Imibhobho yekhonkrithi yekhonkrithi (okanye imibhobho yekhonkrithi, imibhobho ye-acid-i-acid-thayile kunye neminye imibhobho, i-pipes ye-pipe, i-D230, i-D230, njl njl)

Φ imele ububanzi besangqa esiqhelekileyo; Inokumela ububanzi bangaphandle bombhobho, kodwa ngeli xesha kufuneka iphinde iphinde iphindwe ngobukhulu bomhlaba.
