ASTM A53 Dhuumaha Birta
ASTM A53 (ASME A53) tuubada birta kaarboon waa qeexid daboolaysa birta galvanized aan lahayn iyo alxanka leh ee NPS 1/8 ″ ilaa NPS 26. 53 waxaa loogu talagalay cadaadiska iyo codsiyada farsamada sidoo kale waa la aqbali karaa caadiga ah loo isticmaalo uumiga, biyaha, gaaska, iyo khadadka hawada.
Dhuumaha A53 waxay u kala baxaan saddex nooc (F, E, S) iyo laba darajo (A, B).
A53 Nooca F waxaa lagu soo saaray alxanka foornada ama waxaa laga yaabaa inay leedahay alxan joogto ah (Fasalka A kaliya)
Nooca A53 wuxuu leeyahay alxanka caabbinta koronto (Fasalada A iyo B)
Nooca A53 waa tuubo aan waxba tarayn waxaana laga helaa fasalada A iyo B)
A53 Fasalka B bilaa-xun waa badeecadeena ugu badneed ee hoos timaadda qeexitaankan iyo tubbada A53 ayaa caadi ahaan laba-shahaadad u leh A106 B tuubo aan cillad lahayn.
