Xirxirida & Rarista

Loo isticmaalo gudbinta gaaska, biyaha, iyo saliidda labadaba iyo warshadaha gaaska dabiiciga ah iwm.

Casing:Casing waa tubbada dhexroor weyn oo u adeegta sidii dhismeed haynta gidaarada saliidda iyo ceelasha gaaska, ama si fiican u bohol.Waxa la geliya ceel biyood oo sibidh meel lagu shubaa si ay uga ilaaliso in ay burburto iyo godka ceelasha. si loogu oggolaado dareeraha qodista inuu wareego oo soo saaro inuu dhaco.Tuubooyinka Dabooska birta waxay leeyihiin darbi siman & xoogga wax soo saarka ugu yar ee 35,000 psi.

Tuubooyin: Tuubooyinku waa tubbada loo isticmaalo qaadista saliidda cayriin iyo gaasta dabiiciga ah ee laga soo qaado lakabka saliidda ama gaaska ilaa dusha sare ka dib marka la dhammeeyo qodista.Waxaa loo sameeyay si ay ugu adkaysato cadaadiska ka yimaada habka soo saarista.Tuubooyinka waxaa loo soo saaray si la mid ah sida daasadaha, marka laga reebo in habka dheeraadka ah ee loo yaqaan "naxariista" lagu dabaqo si loo adkeeyo tuubooyinka.
