Q345B pā mānoanoa huinahā paipu maikaʻi hōʻoia

(a) E like me ke kaʻina hana - arc welding square tube, resistance welding square tube (kiʻekiʻe alapine a me ka haʻahaʻa alapine), kinoea kuʻihao huinahā paipu a me ka umu ahi kuʻihao huinaha paipu.

(b) Māhele ʻia e ka weld - wili pololei paipu huinaha a me spiral welded square pipe

Nui anawaena manoanoa paia huinahalike paipu ua maheleia i kalapona kila huinahalike paipu a me ka haʻahaʻa alloy huinaha paipu e like me ka mea. Hoʻokaʻawale ʻia ke kila kalapona maʻamau i: Q195, Q215, Q235, SS400, 20 # kila, 45 # kila, etc. Hoʻokaʻawale ʻia nā kila kila haʻahaʻa i Q345, 16Mn, Q390, St52-3, etc.

Paha paipu kila, manoanoa paia huinahalike paipu kila, nui anawaena huinahalike kila paipu, seamless huinahalike kila paipu, haahaa alloy huinahalike paipu kila, 135 * 135 * 10 huinahalike kila paipu, huinaha kila paipu no ka hale kiai, Q345B haahaa alloy huinaha paipu. 20# seamless huinahalike kila paipu

'O ka paipu huinaha, e like me ka inoa, he 'ano o ka paipu huinaha. Hiki i nā mea he nui ke hana i ka paipu huinaha. Hoʻohana ʻia ia, no ka mea e hana ai a ma hea e hoʻohana ai. ʻO ka hapa nui o nā paipu square he paipu kila, ʻo ka hapa nui o nā paipu square structural, decorative square tubes, kūkulu ʻana i nā paipu square, etc.

ʻO ka paipu huinahā he inoa no ka paipu huinaha, ʻo ia hoʻi, paipu kila me ka lōʻihi ʻaoʻao like. Hana ʻia ia me ke kila ʻōwili ʻia ma hope o ke kaʻina hana. ʻO ka mea maʻamau, wehe ʻia ke kila kaulahao, pae ʻia, crimped a welded e hana i ka paipu poepoe, a laila ʻōwili ʻia i loko o kahi paipu huinahā, a laila ʻoki i ka lōʻihi i makemake ʻia. ʻO ka maʻamau 50 mau ʻāpana i kēlā me kēia pūʻolo.

Hiki ke hoʻokaʻawale ʻia nā paipu square i nā seamless a welded. Hoʻokuʻu ʻia nā paipu huinahā like ʻole mai nā paipu pōʻai ʻole. Paha paipu kila, manoanoa paia huinahalike paipu kila, nui anawaena huinahalike kila paipu, seamless huinahalike kila paipu, haahaa alloy huinahalike paipu, 135 * 135 * 10 huinahalike kila paipu, huinahalike kila paipu no ka hale kiai, Q345B haʻahaʻa alloy huinaha paipu. 20# seamless huinahalike kila paipu

1. Ka helu helu hana o ka paipu huinaha - plasticity

ʻO ka plasticity e pili ana i ka hiki i nā mea metala ke hana i ka deformation plastic (deformation mau) me ka ʻole o ka pōʻino ma lalo o ka ukana.

2. Ka helu helu hana o ka paipu huinaha - paakiki

ʻO ka paʻakikī kahi kuhikuhi e ana i ka paʻakikī a me ka palupalu o nā mea metala. I kēia manawa, ʻo ke ʻano hana maʻamau i hoʻohana ʻia no ke ana ʻana i ka paʻakikī i ka hana ʻana, ʻo ia ke ʻano paʻakikī indentation. Hoʻohana ʻo ia i kahi indenter me kahi geometry e kaomi i ka ʻili o ka mea metala i hoʻāʻo ʻia ma lalo o kekahi ukana, a hoʻoholo i kona waiwai paʻakikī e like me ke ʻano o ka indentation.

ʻO nā ʻano hana maʻamau ʻo Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) a me Vickers hardness (HV).

3. Ka helu helu hana o ka paipu huinaha - luhi

ʻO ka ikaika, ka plasticity a me ka paʻakikī i kūkākūkā ʻia ma luna nei nā hōʻailona āpau o nā waiwai mechanical o nā metala ma lalo o ka ukana static. ʻO ka ʻoiaʻiʻo, nui nā ʻāpana mīkini e hana ma lalo o ka ukana cyclic, ma lalo e hiki mai ai ka luhi.

4. Ka nānā 'ana i ka papa kuhikuhi hana o ka paipu huinaha - pa'akikī hopena

ʻO ka haʻawe e hana ana ma ka ʻāpana me ka wikiwiki nui, ua kapa ʻia ʻo ka haawe hopena, a ʻo ka hiki o ke metala ke pale aku i ka hāʻule ʻole ma lalo o ka haʻahaʻa hopena i kapa ʻia ʻo ka paʻakikī hopena.

5. Hana helu helu ana o ka huinahalike paipu - ikaika huinahalike kila paipu, manoanoa paia huinahalike kila paipu, nui anawaena huinahalike kila paipu, seamless huinahalike kila paipu, haʻahaʻa alloy huinaha kila paipu, 135 * 135 * 10 huinahalike kila paipu, huinahalike kila paipu no ka hale kiai puo. , Q345B haʻahaʻa alumina huinahalike paipu kila, 20 # seamless huinahalike kila paipu

ʻO ka ikaika e pili ana i ke kūpaʻa ʻana o nā mea metala i ka hāʻule ʻole (ka hoʻololi ʻana o ka plastic 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 ʻāʻī, ka hoʻopaʻa ʻana, ke kuʻi ʻana a me ka ʻāʻī, ua māhele ʻia ka ikaika i ka ikaika tensile, ka ikaika compressive, ka ikaika flexural a me ka ikaika shear. Loaʻa pinepine kahi pilina ma waena o nā ikaika like ʻole. ʻO ka maʻamau, hoʻohana ʻia ka ikaika tensile ma ke ʻano he hōʻailona ikaika loa.
