Q235 pahu pahu me ke kiʻekiʻe a me ke kumu kūʻai haʻahaʻa
Q235 welded square paipu mea he appellation o huinahalike paipu, 'o ia hoʻi, kila paipu me ka like ka lōʻihi aoao. Hana ʻia ia me ke kila ʻōwili ʻia ma o ka ʻenehana ʻenehana. ʻO ka mea maʻamau, wehe ʻia ke kila kaulahao, palahalaha, wili a wili ʻia e hana i ka paipu poepoe, a laila ua ʻōwili ʻia ka paipu poepoe e nānā i ka paipu huinahā Q235 welded, a laila ʻoki i ka lōʻihi i makemake ʻia. ʻO ka mea maʻamau he 50 mau ʻāpana no ka pūʻolo. ʻO ka ikaika e pili ana i ka hana o Q235 welded square tube e pale aku i ka luku (kūpono i ka plastic deformation a i ʻole ka haki ʻana) ma lalo o ka haʻahaʻa paʻa. No ka mea, ʻo nā ʻano hana o ka ukana e pili ana i ka tension, contraction, meandering, shear a pēlā aku, no ka mea, ua māhele ʻia ka ikaika i ka ikaika tensile, ka ikaika compressive, ka ikaika flexural, ka ikaika shear a pēlā aku. Loaʻa pinepine kahi pilina paʻa ma waena o nā ikaika like ʻole. I ka hoʻohana maʻamau, ʻo ka ikaika tensile ka mea nui loa o ka ana ikaika. Kūʻē ka ikaika i ka mana o ka luku, i kapa ʻia ʻo storming toughness.
ʻO ka ukana ma nā'āpana me ka holomua nui i kapaʻiaʻo ka ukana a me ka pahele. ʻO ka ikaika, plasticity a me ke kihi i kūkākūkā ʻia ma hope, ʻo ia nā hōʻailona hana mīkini o Q215 welded square pipe ma lalo o ka ukana static. I ka hoʻomaʻamaʻa, nui nā mīkini mīkini ma lalo o ka hoʻouka pinepine ʻana, a luhi ka manawa āpau i kēia kaiapuni. ʻO ke kihi luhi he nila ana e kaupaona i ka pae palupalu a paʻakikī o ka ʻikepili metala. I kēia mau makahiki i hala iho nei, ʻo ke ʻano ʻano hoʻoholo ʻokoʻa i loko o ke ʻano ʻo ka paʻi i ke ʻano angle. Hoʻohana ia i ka indenter me kahi helu a me ke ʻano e kaomi i ka ʻili o ka ʻikepili o Q235 welded square tube ma lalo o kahi haʻahaʻa, a i loko e hoʻoholo i kona kumukūʻai angle e like me ka paʻi ʻana i ka pae. ʻO nā ʻano hana maʻamau e pili ana i ka kihi Brinell (HB), ʻo Rockwell angle (HRA, HRB, HRC) a me Vickers angle (HV). ʻO ka angular plasticity e pili ana i ka mana o ka plastic deformation (permanent deformation) me ka luku ʻole ʻia o nā mea metala ma lalo o ka ukana. Plastic Q215 welded square tube non-standard seamless square tube is extruded from seamless circular tube. He ʻoiaʻiʻo ka ʻokoʻa ma waena o ka paipu square seamless a welded. He ʻano paipu huinahā (retangular tube). Hiki i ka ʻuhane o nā mea he nui ke hana i ke kino o ka paipu huinahā (retangular tube). ʻO kona ʻano, no ke aha a me kahi i hoʻohana ʻia ai. ʻO ka hapa nui o ka Q215 welded square tubes he kila paipu, ʻo ka hapa nui o nā paipu square structural, nā paipu square keʻokeʻo, ke kūkulu ʻana i nā paipu huinahā (rectangular tubes), etc.
Hiki ke hana i ka paipu wiliwili me ka anawaena paipu nui, a hiki i ka blank me ka laula like ke hana i ka paipu wili me ka anawaena paipu like ole. Eia nō naʻe, ke hoʻohālikelike ʻia me ka paipu square seam pololei me ka lōʻihi like, piʻi ka lōʻihi weld e 30 ~ 100%, a haʻahaʻa ka wikiwiki o ka hana.
ʻO nā paipu huinahā welded me ke anawaena nui a mānoanoa paha i hana ʻia me ke kila blank pololei, ʻoiai ʻo nā paipu wili liʻiliʻi a me nā paipu wiliwili paia lahilahi e pono ke wili pololei ʻia ma o ke kaula kila. A laila ma hope o ka poli maʻalahi, ua OK ke kaha kiʻi uea. No laila, hoʻohana nui ʻia ka wili wili pololei no nā paipu wiliwili liʻiliʻi, a hoʻohana nui ʻia ka wiliwili spiral no nā paipu welded nui.
ʻO nā mea maʻamau o nā paipu square welded: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0ncrb18ni9, 0Cr18ni9, 0cr18ni9, 0cr18ni9, 0cr18ni9, 0cr18ni9, 0cr18, etc.
Welded kuhiliʻole kila paipu no ka hoʻonani (GB / T 18705-2002), kuhiliʻole kila welded paipu no ka hale hoʻonani (JG / T 3030-1995), nui anawaena welded kila paipu no ka haʻahaʻa puʻe wai lawe (GB / T 3091-2001), a me ka paipu kila welded no ka mea hoʻololi wela (yb4103-2000).
