LSAW Piling Pipe A252 GR.3
ASTM A252 GR3 yog kev lag luam - tus qauv specification rauwelded thiab seamless steel yeeb nkab pawg. Tsis zoo li tus qauv "kua" kav (xws li ASTM A53 lossis API 5L), A252 GR3 kav yog tsim tshwj xeeb raukev siv tus qauv. Lawv lub luag haujlwm tseem ceeb yog ua haujlwm ruaj khov -cov tswv cuab lossis ua lub plhaub los ua cov cam khwb cia-hauv- tso cov pob zeb ua vaj tse.
