ASTM A139 / A139M yog cov qauv tshwj xeeb rau hluav taws xob fusion (arc) welded steel yeeb nkab (NPS 4 thiab siab dua). Cov txheej txheem no suav nrog tsib qib ntawm hluav taws xob fusion (arc) welded ncaj los yog kauv seam steel yeeb nkab rau kev xa cov kua, gases, lossis chav. Lub nominal phab ntsa thickness ntawm no series ntawm steel yeeb nkab yog feem ntau 1.0 ntiv tes (25.4 mm) thiab hauv qab no.
