Mea hoʻolako kūlana kiʻekiʻe o ka paipu kila seamless square

ʻO ka wehewehe pōkole:

Ke ano o ka halihali ana:kai a ea paha

Hoʻopili:paʻa i loko o nā pahu lāʻau

ʻO ka manawa maʻamau ka lōʻihi o ka lawe ʻanaʻO 4000mm-12000mm, me 6000mm a me 12000mm i ka hapa nui

Hoʻohana:ka lawe ʻana i ka pipeline, pipeline boiler, wili ʻaila/gas, meaʻai/inu/hua waiu, ʻoihana mīkini, ʻoihana kemika, mining, hoʻonani hale, hoʻohana kūikawā

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.
