Kiʻekiʻe Kina ASME / API / GOST / DIN / En / JIS Seamless a Welded Steel Pipe
Nānā nui
ʻO nā mea a pau a mākou e hana ai e pili pū me kā mākou ʻōlelo " Shopper mua, hilinaʻi ma mua, e hoʻolaʻa ana a puni ka ʻeke meaʻai a me ka palekana o ke kaiapuni no High Quality Seamless and Welded Steel Pipe, Hoʻokomo mākou i ke kuleana maoli a me ke olakino. ʻO nā hui kālepa honua i puka mai ʻAmelika ʻO mākou kāu hoa ʻoihana e pili ana i ke kumu o "Enterprising and Truth-Seeking, Preciseness and Unity", me ka ʻenehana ke kumu, hoʻomau kā mākou hui i ka hoʻolako ʻana iā ʻoe. me nā huahana kiʻekiʻe loa a me ka lawelawe ma hope o ke kūʻai aku ke manaʻoʻiʻo nei mākou: he kūlana koʻikoʻi mākou.
Ma waena o nā mea hana maʻamau maʻamau seamless steel pipe, DIN1629 ST52 kekahi o nā mea i hoʻohana pinepine ʻia. Ma nā kūlana Kina, ua like ia me GB/T8162 Q345B. Hiki ke hoʻololi ʻia nā mea ʻelua no kekahi i kekahi, akā ʻaʻole i kūpono loa. .
Ma ke ʻano o ka haku mele ʻana:
DIN 1629 ST52: C: 0.17% ka nui; P: 0.04% ka nui; S:: 0.04% ka nui; N: 0.009% ka nui
GB/T 8162 Q345B: C: 0.2%max; P: 0.035% ka nui; S:: 0.035% ka nui; N: 0.012% ka nui
Hiki ke ʻike ʻia ke ʻōlelo pū ʻia nā maʻamau ʻelua he ʻano like ke ʻano o nā mea kemika.
Hana mīkini:
DIN 1629 ST52: Ka ikaika tensile: 500 ~ 650Mpa; Ka ikaika hua: 335 ~ 355Mpa; Elongation (longitudinal): 21% min
GB / T 8162 Q345B: Ka ikaika tensile: 470 ~ 630Mpa; Ka ikaika hua: 295 ~ 345Mpa; Elongation (longitudinal): 20% min
ʻO nā koi no nā waiwai mechanical o nā mea ʻelua he ʻano like nō hoʻi
Nā mea ho'āʻo:
Pono ka DIN 1629 i ka ho'āʻo tensile, ka ho'āʻo hoʻopalapala, ka ho'āʻo paʻa, ka nānāʻana i kaʻili, ka nānāʻana i ka dimensional; hoʻopau ʻana i nā huahana
Pono ʻo GB/T8162 Q345B i ka nānā ʻana i ka haku mele, hoʻāʻo tensile, hoʻāʻo paʻakikī, hoʻāʻo hopena 20 ℃, hoʻāʻo palahalaha, hoʻāʻo kulou, hoʻāʻo uila non-destructive.
Hiki ke ʻike ʻia nā koi o ka papahana hoʻokolohua o GB/T8162 Q345B e uhi pono ana i ka DIN1629
Nā koi hoʻomanawanui:
ʻO DIN1629 ka mea e ʻōlelo ai:

Ua like nō hoʻi ka ʻae ʻana o nā mea ʻelua
No laila, hiki ke hoʻololi i ka Q345B a me ST52 i kekahi i kekahi ke hoʻohanaʻia i kahi kūlana maʻamau aʻaʻohe koi kūikawā. Ke ʻoi aku ka paʻakikī o ke kaiapuni a i ʻole nā koi, pono e noʻonoʻo pono ka hoʻohālikelike.
