ASTM A519 4130 Mea Mechanical Seamless Steel Tube
ʻO ka wehewehe pōkole:
He ʻano paipu me ka mānoanoa o ka paia ma mua o ka awelika.Hoʻohana ʻia kēia mau mea i nā ʻoihana petrochemical, ʻoihana kemika a me nā ʻoihana nuklea.ʻO mākou nā mea kūʻai aku ma Kina e kū nei i nā pilikia kaumaha a me nā pilikia ma muli o ka ikaika o ka pā.Hoʻokomo pū ʻia nā noi i ka aila a me ke kinoea, nā wahi noiʻi a me ka hoʻomohala ʻana, nā ʻoihana pale a me nā pulp a me nā wili pepa.Hōʻailona ʻia ka paipu maʻemaʻe ʻole o ka paia me nā helu hoʻonohonoho paʻa paʻa e like me EH, XH a me XS.
Loaʻa iā mākou nā mea hana hou.Hoʻokuʻu ʻia kā mākou mau waiwai i USA, UK a pēlā aku, e hauʻoli ana i kahi kūlana maikaʻi loa i waena o nā mea kūʻai no ASTM A519 4130 Material Mechanical Seamless Steel Tube, Ua hoʻolaʻa mākou e hāʻawi i ka ʻenehana hoʻomaʻemaʻe ʻike a me nā koho no ʻoe iho!
Loaʻa iā mākou nā mea hana hou.Hoʻokuʻu ʻia kā mākou waiwai i USA, UK a pēlā aku, e hauʻoli ana i kahi kūlana maikaʻi loa i waena o nā mea kūʻai akuPaipu a me Paipu Kina, ʻO kā mākou hui, e pili mau ana i ka maikaʻi e like me ke kumu o ka ʻoihana, e ʻimi ana i ka hoʻomohala ʻana ma o ka hilinaʻi kiʻekiʻe, e mālama pono ana i ka ISO9000 quality management standard, e hoʻokumu ana i ka ʻoihana kiʻekiʻe e ka ʻuhane o ka holomua ʻana i ka ʻoiaʻiʻo a me ka manaʻolana.
Aia nā papa manawa like ʻole i kēia mau paipu i ko lākou lawelawe ʻana i nā pae like ʻole.Loaʻa nā sch 80, 100, 120, 140 a me 160 i loaʻa nā pā kaumaha.Hiki ke pālua ka ikaika o ka paipu maʻemaʻe ka mānoanoa o ka pā i kekahi manawa a ua kapa ʻia ʻo XXS a i ʻole XXS.Hiki ke ʻokoʻa ka mea no ka mea aia nā māka like ʻole o ke kila kalapona i hoʻohana ʻia no ka hana ʻana i nā ʻano paipu kila kalapona mānoanoa o ka paia.ʻO ka leo kiʻekiʻe, kahe kiʻekiʻe, nā ʻōnaehana kiʻekiʻe e like me ka aila a me nā laina hoʻouna ʻana i ke kinoea, nā laina wai, a me nā ʻōnaehana hoʻoheheʻe mana i hoʻohana i nā ʻano like ʻole.
Hoʻohana nui ʻia nā paipu kila mānoanoa i ka mālama ʻana i ka wai, petrochemical, kemika, ka mana uila, ka wai mahiʻai, ke kūkulu kūlanakauhale a me nā ʻoihana ʻē aʻe.No ka lawe ʻana i ka wai: hoʻolako wai a me ka wai.Ka lawe kinoea: kinoea maoli, mahu, kinoea petroleum liquefied.Nā hoʻohana ʻana i ke kūkulu ʻia: hoʻohana ʻia ma ke ʻano he alahaka pilang paipu;nā pā, nā alanui, nā hale a me nā hale ʻē aʻe.
ʻO ke kī i ka maikaʻi o nā paipu kila mānoanoa e pono ke kūlike ka mānoanoa.Pili pono ka mānoanoa pā o nā paipu kila mānoanoa i ka maikaʻi a me ka hana pono o nā paipu kila, nā paipu kila mānoanoa, a me nā paipu kila ʻole ke anawaena.Hoʻohana maʻamau ia no ka hoʻoili ʻana a me ka hoʻoili ʻana i nā ʻāpana pā mānoanoa.,,ʻo ka mānoanoa o ka paia o ka paipu kila e pili pono i ka maikaʻi o nā'āpana hana hope,ʻaʻole i hoʻomaluʻia ka paia o ka paipu kila mānoanoa, aʻaʻole koʻikoʻi ka maikaʻi o ke kila.
ʻO nā paipu kila mānoanoa e pili ana i nā paipu kila me ke anawaena paipu i ka mānoanoa o ka paia o lalo o 20. Hoʻohana nui ʻia no ka petroleum geological drill pipes, petrochemical crack pipes, boiler pipe, bearing pipes and high-precision structural pipes for automobiles, tractors and mokulele.ʻO ka maikaʻi o nā paipu kila maʻemaʻe ʻole i ka paia ma muli o ke kūlike o ka mānoanoa o ka pā.

ʻO ka mechanical waiwai o ke kaumaha wallthickness kila paipu mea he koʻikoʻi kuhikuhipuʻuone e hōʻoia i ka hope hoʻohana hana (mechanical waiwai) o kaumaha wallthickness kila paipu kila paipu, a ua hilinaʻi ma luna o ka kemikala haku mele a me ka wela wela nenoaiu o ka paipu kila.No laila, e like me nā koi noi like ʻole, ua hoʻolauna ʻia nā ʻano mechanical o nā paipu kila pale ikaika mai nā ʻano o ka ikaika tensile, yield point, a me ka elongation.
1. Ka ikaika tensile
Ma ke kaʻina hana tensile, ʻo ka ikaika kiʻekiʻe loa (Fb) i lawe ʻia e ka hāpana i ka wā e haki ai, ʻo ia ke koʻikoʻi (σ) i loaʻa mai ka ʻāpana keʻa mua (So) o ka hāpana, i kapa ʻia ʻo ka ikaika tensile (σb), a ʻo ka ʻāpana N/mm2 (MPa).Hōʻike ia i ka hiki ke kiʻekiʻe loa o kahi mea metala e pale aku i ka pōʻino ma lalo o ka ikaika tensile.
2. Lae hua
No ka mea metala me kahi hanana hua, ʻo ke koʻikoʻi i hiki ai i ka hāpana ke hoʻomau i ka lōʻihi me ka piʻi ʻole o ka ikaika i ka wā o ke kaʻina hana (e mau ana) ua kapa ʻia ʻo ka helu hua.Inā hāʻule ka ikaika, pono e hoʻokaʻawale ʻia nā helu o luna a me lalo.N/mm2 (MPa) ka wae o ka helu hua.
3. Elongation ma hope o ka haki ʻana
I ka ho'āʻo tensile, ua hoʻonui ʻia ka pākēneka o ka lōʻihi o ka lōʻihi ma hope o ka haki ʻana o ka hāpana i ka lōʻihi kumu mua i kapa ʻia ʻo ka elongation.Hōʻike ʻia e σ, ʻo ka ʻāpana he %.
Loaʻa iā mākou nā mea hana hou.Hoʻokuʻu ʻia kā mākou waiwai i USA, UK a pēlā aku, e hauʻoli ana i kahi kūlana maikaʻi loa i waena o nā mea kūʻai aku no ka hoʻemi nui ʻana i ka ASTM A519 4130 Material Mechanical Seamless Steel Tube, Ua hoʻolaʻa mākou e hoʻolako i ka ʻenehana hoʻomaʻemaʻe ʻike a me nā koho no ʻoe iho!
Hoʻemi nuiPaipu a me Paipu Kina, ʻO kā mākou hui, e pili mau ana i ka maikaʻi e like me ke kumu o ka ʻoihana, e ʻimi ana i ka hoʻomohala ʻana ma o ka hilinaʻi kiʻekiʻe, e mālama pono ana i ka ISO9000 quality management standard, e hoʻokumu ana i ka ʻoihana kiʻekiʻe e ka ʻuhane o ka holomua ʻana i ka ʻoiaʻiʻo a me ka manaʻolana.
