ASTM A671 ni umuyoboro wibyuma bikozwe mubisahani byubwiza,Amashanyarazi-Fusion-Weld (EFW)kubidukikije byumuvuduko mwinshi kubidukikije no hasi yubushyuhe.
Birakwiriye cyane cyane kubisabwa bisaba umuvuduko ukabije hamwe nubushyuhe bwihariye.
Kugenda Utubuto
ASTM A671 Ingano Urwego
Urwego rusabwa: imiyoboro y'ibyuma ifite DN ≥ 400 mm [16 muri] na WT ≥ 6 mm [1/4].
Irashobora kandi gukoreshwa kubindi bipimo byumuyoboro, mugihe byujuje ibindi bisabwa byose.
ASTM A671 Ikimenyetso
Kugirango twumve neza ASTM A671, reka tubanze twumve ibiyiranga.Ibi bifasha gusobanura urugero rwibisabwa nibiranga iki gipimo.
Urugero rwo Gushyira ikimenyetso:
