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 darajooyin 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.

ASTM A106 tubbada darajada B waxay kiimiko ahaan u dhigantaa ASTM A53 Fasalka B iyo API 5L Fasalka B marka loo eego booska kiimikaad iyo sifooyinka farsamada, guud ahaan iyadoo la isticmaalayo birta kaarboon, oo leh ugu yaraan wax soo saarkiisu yahay 240 MPa iyo xoogga xajinta ee 415 MPa.
Tilmaamaha Heerka ASTM A106 ee Dhuumaha Birta aan Xumaan lahayn waxay leedahay saddex darajo, ASTM A106 Gr.A.B iyo C, mar kasta oo ay ka sarreeyaan darajada maadada, ayaa ka sii wanaagsan sifooyinka xoogga.
Hababka tijaabada ee ASTM A106 A, B, C waa imtixaan fidsan, tijaabo korantada aan burburin, tijaabada ultrasonic, test eddy current, test flux leakage test, hababka tijaabadan waa in la ogeysiiyaa ama lagala hadlaa macaamilka si loo go'aamiyo imtixaanka la samayn doono. loo isticmaalo.
