ASTM A192 Siab Siab Boiler Tube

GNEE Group tsim thiab khoom siv ASTM A192 yam tsawg kawg nkaus phab ntsa thickness carbon steel boiler thiab superheater raj rau kev siv siab. GNEE Group yuav ua cov kev ntsuam xyuas hauv qab no ntawm A192 boiler raj, uas yog: kev sim flattening, flaring test, hardness test thiab hydraulic test, los xyuas kom meej qhov zoo ntawm cov yeeb nkab steel.

Yog tias koj xav tau A192 steel kav, thov koj xav tiv tauj peb rau kev tsocai.
