Mea hoʻolako kūlana kiʻekiʻe o ka paipu kila seamless square
Seamless square kila paipu, He mea paakiki martensitic kuhiliʻole kila.ʻOkoʻa mai ka papa austenite
Hiki ke mālama ʻia ka wela ("quenched and tempered") e hana i ka ikaika kiʻekiʻe a me ka ductility maikaʻi.I ka wā e koi ʻia ai ka ikaika, ka paʻakikī a me ke kūpaʻa ʻana a loaʻa iā ia kahi kūʻē corrosion
Ma muli o ka paʻakikī paʻakikī o kēia kila, e hoʻopili ʻia nā waiwai ʻē aʻe o kēia mea a me nā waiwai i loaʻa i kekahi ʻano.Hiki ke hoʻohana maikaʻi wale ʻia ka huila ma nā wahi ʻino haʻahaʻa.Ua kaupalena ʻia ka pae wela o ka hana a) ʻo ka hoʻohaunaele nui ʻana i nā wela kiʻekiʻe ka hopena o ka nalo ʻana o ka ikaika a me ka b) ka nalowale o ka ductility ma nā mahana sub-zero.
Seamless square steel tubing, He mea kūpono kēia kila no ka hana ʻana i nā ʻāpana koʻikoʻi kiʻekiʻe ma nā ʻano ʻoihana like ʻole, me ka petrochemical, automotive a me ka hana mana.
Pahu hao huinaha holo ole, ka hana nui
1. ʻO ka plastic
ʻO ka plasticity e pili ana i ka hiki o kahi mea metala ke hana i ka deformation plastic (permanent deformation) me ka ʻole o ka pōʻino ma lalo o ka ukana.
2. Ka paakiki
ʻO ka paʻakikī kahi ana o ka paʻakikī a i ʻole ka palupalu o kahi mea metala.Ma keia ola ana i ka hana ana o ka paakiki ana ano ka mea maʻamau i hoʻohana 'ia i loko o ka indenter paakiki 'ano, ka mea, e hoʻohana i kekahi geometric kinona o ka indenter poo ma lalo o kekahi haawe i loko o ka ili o ka metala mea e ho'āʻo ai, e like me. ke degere o ka indenter e hoʻoholo i ka waiwai paʻakikī.
ʻO nā ʻano hana maʻamau ʻo Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) a me Vickers hardness (HV) a me nā ʻano hana ʻē aʻe.
3. Ka luhi
ʻO ka ikaika, ka plasticity a me ka paʻakikī nā hōʻailona o nā waiwai mechanical o nā metala ma lalo o ka ukana static.ʻO ka ʻoiaʻiʻo, nui nā ʻāpana mīkini e hana ʻia ma lalo o nā ukana cyclic, a hiki ke luhi ma lalo o kēia mau kūlana.Pono ke ala e loaʻa i nā ʻano ʻāpana ʻē aʻe o ka paipu kila kūikawā.
ʻIke ʻia ka paipu welded maʻamau, ʻike nui ʻia ʻo ka paipu ʻeleʻele.He paipu kila welded i hoʻohana ʻia no ka lawe ʻana i ka wai, ke kinoea, ka ea, ka ʻaila, ka mahu mehana a me nā mea ʻē aʻe.Hoʻokaʻawale ʻia ka mānoanoa pā o ka paipu kila i ka paipu kila maʻamau a me ka paipu kila mānoanoa.Hoʻokaʻawale ʻia ke ʻano o ka paipu i loko o ka paipu kila non-rebar (light tube) a me ka rebar steel tube.Hōʻike ʻia nā kikoʻī o ka paipu kila e ke anawaena nominal (mm), kahi kokoke i ke anawaena o loko.He mea maʻamau ka hoʻohana ʻana i nā iniha, e like me 11/2.ʻO ka paipu kila welded i hoʻohana ʻia no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa i hoʻohana nui ʻia e like me ka paipu kumu o ka galvanized welded steel pipe i hoʻohana ʻia no ka lawe haʻahaʻa haʻahaʻa.
ʻO ka paipu kila welded galvanized no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa (GB/T3091-1993) ʻike ʻia ʻo ia he paipu kila wiliwili uila, ʻike mau ʻia he paipu keʻokeʻo.He paipu kila i hoʻohana ʻia no ka lawe ʻana i ka wai, ke kinoea, ka aila ea, ka mahu wela, ka wai mehana a me nā mea ʻē aʻe.Hoʻokaʻawale ʻia ka mānoanoa o ka pā o ka paipu kila i nā paipu kila galvanized a me nā paipu kila galvanized.Hoʻokaʻawale ʻia ka hopena o ka paipu i ka paipu kila galvanized me ka ʻole o ke kaula a me ka paipu kila galvanized me ke kaula.
Hoʻohana ʻia ka uea kalapona maʻamau (GB3640-88) no ka pale ʻana i ka uea ma nā hale ʻoihana a me nā hale kīwila, nā mīkini hoʻonohonoho a me nā mea hana a me nā papahana hoʻonohonoho uila.
ʻO ka paipu kila i hoʻopaʻa ʻia i ka hili pololei (YB242-63) he paipu kila me nā welds like longitudinally.Hoʻokaʻawale pinepine ʻia i loko o ka metric welded steel pipe, welded thin-wall pipe, transformer cooling tubing a pēlā aku.
ʻO ka paipu kila i hoʻopaʻa ʻia i loko o ke awāwa i hoʻopaʻa ʻia (SY5036-83) no ka lawe ʻana i ka wai kaomi, he paipu kila wiliwili ʻia, i hana ʻia me ke kaula hao ʻōwili wela e like me ka paipu ʻole, hana pinepine ʻia i ka mahana wela a wili ʻia e ka ʻaoʻao lua ʻaoʻao. .Loaʻa i ka paipu kila ka mana haʻahaʻa a me ka hana wili maikaʻi.He palekana a hilinaʻi hoʻi i ka hoʻohana ʻana ma hope o nā ʻano ʻike ʻepekema koʻikoʻi a me ka hoʻāʻo ʻana.Nui anawaena kila paipu, kiʻekiʻe hoʻoili pono pono, a hiki ke hoola i ka hoʻokomo o ka pipeline kau.Hoʻohana nui ʻia no ka lawe ʻana i ka aila a me nā pipeline kinoea kūlohelohe.
