Iipali zombiyelo zombane zehagu zisetyenziselwa ukwakha ucingo olumdaka ngombane. Ngokubanzi, iipali zombiyelo zombane ze pigtail zenziwe ngentsimbi yasentwasahlobo ngombane ogqunywe ngombane, kunye nokuqina ngakumbi emva kokugoba, kwaye kunzima ngakumbi kunesithuba sombane sombane esenziwe ngentsimbi ye-Q235, ububanzi obukhoyo yi-6mm, 7mm kunye ne-8mm, kunye ubude bungenziwa ngokwezifiso, ngesiqhelo ubude obupheleleyo buba kwi-106cm.

Inqaku eliphambili lezithuba zombane zombane we-pigtail zezi zilandelayo:

1. umbhobho.
umbhobho yindibaniselwano yeHDPE kunye ne-LLDPE, enebanga eliphezulu le-UV inhibitor, engqine unyango lwasemva kwemveliso yethumbu ukukhupha uxinzelelo ngaphakathi.

2. umphezulu ukutyabeka umphezulu.
inqanaba eliphezulu le-PET yokugaya umgubo, kusetyenziswa izinto ezivela kwinkampani yaseTaiwan, yesibini kuphela ukuya kwipeyinti yeAkzoNobel.

3. icandelo elinyukayo.
Inxalenye yokunyathela ngamacala amabini e-weld, hayi icala nje, kuba intsimbi yasentwasahlobo inamaqhekeza, amacala amabini e-welding omelele ngakumbi.
