Liphaephe tse welded ka spiral bakeng sa Mohala oa Khase ea Tlhaho o ka Tlas'a Lefatše

Liphaephe tse tjheseditsweng ka moya bakeng sa Mohala wa Khase ya Tlhaho o ka Tlase ho Lefatshe Setšoantšo se Hlahisitsoeng

Tlhaloso e Khutšoanyane:

Re hlahisa sehlahisoa sa rona sa morao-rao - phaephe e welded ka spiral, e leng karolo ea bohlokoa ea sistimi ea phetisetso ea liphaephe tsa khase ea tlhaho tse ka tlas'a lefatše.
