'O kēia ka'ina hana he 'ano kila kūikawā 'ano iwi iwi / kumu waiwai Q235B welded paipu / huina ki'eki'e 45 mika / huina span 115 mika / huina lō'ihi 1577 mika.
1. ʻO ke kila i hoʻohana ʻia i loko o ke kiʻi kila kila e loaʻa i ka ikaika tensile, elongation, ka ikaika hua a me ka sulfur a me ka phosphorus maʻiʻo, a loaʻa pū kekahi i ka hōʻoia kūpono o ka ʻike kalapona.
2. ʻO nā kila a pau he mau kila kila, a e hoʻokōʻia i ka ho'āʻo tensile, ka ho'āʻo kulou, a me ka ho'āʻo hopena V-notch e like me nā koi hoʻolālā, a e hoʻokō pū i nā koi o ka weldability.
3. ʻO nā mea kila a pau e like me nā kaola a me nā kolamu i hana ʻia i ke kila Q355B, e ʻike i nā koi kiʻi no nā kikoʻī.ʻO nā kūlana maikaʻi o nā mea e hoʻokō i nā koi o ke kūlana aupuni o kēia manawa "Low Alloy High Strength Structural Steel" (GB/T 1591-2018).ʻO ka ikaika tensile, elongation, yield point, cold bending test and impact toughness of the material e pono e hōʻoia ʻia e kūpono, a ʻo ka ʻike o ka sulfur, phosphorus a me ke kalapona e pono e hoʻokō i nā koi.
4. I ka wā hoʻolālā seismic, e hoʻokō ke kila i kēia mau koi:
ʻAʻole pono eʻoi aku ka nui o ka nui o ke ana o ka ikaika o ke kila i ka waiwai o ka ikaika tensile ma mua o 0.85;
Pono e loaʻa i ke kila nā ʻanuʻu hua, a ʻaʻole e emi ka elongation ma lalo o 20%;
Pono ke kila i ka weldability maikaʻi a ʻae ʻia ka paʻakikī hopena.
5. Nā mea wiliwili，
Pono e hoʻohālikelike ʻia ka mea hoʻohui kuʻi me ka metala kumu.Ke wili ʻia nā māka kila like ʻole, hoʻohana ʻia ka electrode a i ʻole ka uea i kūpono i ka pae kila ikaika haʻahaʻa.Pono e hoʻohana ʻia nā mea hoʻohui welded me ka haʻahaʻa ikaika a i ʻole ka wiliwili pālahalaha koʻikoʻi e hoʻohana i nā electrodes haʻahaʻa-hydrogen, e like me E4315, E4316, E5015, E5016 a me nā kumu hoʻohālike ʻē aʻe.
