Zonse zomwe timachita nthawi zambiri zimakhala zogwirizana ndi mfundo yathu " Shopper choyamba, Dalirani poyamba, kuyika zakudya ndi chitetezo cha chilengedwe cha High Quality Seamless ndi Welded Steel Pipe, Timayika zenizeni ndi thanzi ngati udindo waukulu. Tsopano tili ndi katswiri. Gulu lazamalonda lapadziko lonse lapansi lomwe lamaliza maphunziro awo ku America. ndi ukadaulo monga pachimake, kampani yathu ikupitiliza kupanga, odzipereka kukupatsirani zinthu zotsika mtengo kwambiri komanso ntchito yosamala pambuyo pogulitsa Timakhulupirira kuti: ndife otsogola chifukwa ndife apadera.

Pakati pa zida zachitsulo zopanda msoko, DIN1629 ST52 ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri. Pamiyezo yaku China, nthawi zambiri imagwirizana ndi GB/T8162 Q345B. Awiriwo akhoza kulowetsedwa m'malo mwa wina ndi mzake, koma sakugwirizana kwathunthu. .

Zofunikira zamakina azinthu ziwirizi ndizofanana

Zoyeserera:

DIN 1629 imafuna kuyesedwa kwamphamvu, kuyesa kosalala, kuyesa kulimba, kuyang'ana pamwamba, kuyang'ana mozama; anamaliza kusanthula mankhwala

GB/T8162 Q345B imafuna kuyang'ana kwa mankhwala, kuyesa kwamphamvu, kuyesa kuuma, kuyesa kwa 20 ℃, kuyesa kwa flattening, kuyesa kupindika, kuyesa magetsi osawononga.

Zitha kuwoneka kuti zoyeserera zamaprojekiti a GB/T8162 Q345B kwenikweni zimaphimba DIN1629
