Pìoba trenchless HDPE
tuairisgeul goirid:
Thòisich pìob gun trench PE anns na 1970n agus chaidh a thoirt a-steach do Shìona anns na 1990n.An-dràsta, tha e air a chleachdadh gu bitheanta airson an achadh pìoba 'togail, leithid solar uisge, drèanadh, dealan agus conaltraidh pìoba.Cuideachd, tha e air a chur an sàs gu farsaing ann an raon ath-nuadhachadh loidhne-phìoban, dìon cuimhneachan cultarail agus seann togalaichean, agus mar sin air adhart.
