ASTM A106 Gr.B Tubooyinka Birta aan Xumaan lahayn Sawirka

Sharaxaad Gaaban:

ASTM A106/ASME SA106 waa qeexitaanka caadiga ah ee tuubooyinka birta kaarboonka ee aan fiicnayn ee codsiyada heerkulka sare.Waxay ka kooban tahay saddex darajo A, B iyo C, darajada sida caadiga ah loo isticmaalo waa A106 fasalka B. Looma isticmaalo oo keliya hababka dhuumaha sida saliidda iyo gaaska, biyaha, iyo gaadiidka slurry, laakiin sidoo kale in kuleyliyaha, dhismaha iyo codsiyada dhismaha.
