ASTM A139 SSAW Carbon Steel Yeeb Nkab
ASTM A139 yog tus qauv specification rau electrofusion (arc) welded steel yeeb nkab (NPS 4 thiab siab dua).
ASTM A139 SSAW Carbon Steel Pipe Qhov kev qhia tshwj xeeb no suav nrog tsib qib ntawm electrofusion (arc) welded kauv seam steel yeeb nkab. Cov yeeb nkab no yog siv los thauj cov kua, gases lossis vapors. Kauv seam steel kav nrog txheej diameters ntawm 219mm txog 3500mm thiab phab ntsa thickness ntawm 25.4mm.
SSAW stands rau "submerged arc welding" thiab yog ib txoj hauv kev siv los vuam steel yeeb nkab pob qij txha. SSAW yeeb nkab yog tsim los ntawm kev tsim cov coils ntawm kub dov hlau rau hauv cov duab cylindrical thiab tom qab ntawd vuam cov seams siv submerged arc vuam.
ASTM A139 kauv steel yeeb nkab yog siv los thauj cov kua dej xws li roj, nkev, dej, thiab lwm yam., nrog rau cov khoom siv dav dav xws li txuas hniav, tsev, thiab lwm yam.
