| Hoʻokaʻawale | ʻO ka paipu kila uʻi anu, paipu kila wela | Ka laulā o ka noi | Ka hana, nā mīkini, ka lua lanahu, ʻoihana kemika, mana uila, kaʻa kaʻa, ʻoihana kaʻa, alaloa, alahaka, ipu, nā mea haʻuki, nā mīkini mahiʻai, nā mīkini ʻaila, nā mīkini ʻimi e hoʻonui |
| Ka lōʻihi | 6m ka lōʻihi paʻa | ||
| Ka mānoanoa o ka paia (mm) | 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5 |
1.Ka ikaika uʻi (σb): ʻO ka ikaika kiʻekiʻe loa (Fb) i loaʻa i kahi mea hoʻohālike i ka haʻalulu i ka wā i huki ʻia ai, i puʻunaue ʻia e ke koʻikoʻi (σ) i loaʻa mai ka ʻāpana keʻa mua (So) o ka mea hoʻohālike, ua kapa ʻia ʻo ka ikaika tensile ( σb), ma 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 ʻuʻuku.ʻAuhea: Fb - ka ikaika kiʻekiʻe loa e kū ai ke kiʻi i ka wā e huki ʻia ai, N (Newton);No laila - ka ʻāpana keʻa kumu mua o ka specimen, mm2.
2.kiko hua (σs): mea metala me ka mea hoʻohua, ke koʻikoʻi i ka wā e hiki ai ke hoʻomau i ka hoʻonui ʻana o ka mana me ka ʻole o ka hoʻonui ʻana i ka ikaika (e noho mau) i ka wā o ke kaʻina hana, i kapa ʻia ʻo ke kiko hua.Inā emi ka ikaika, pono e hoʻokaʻawale ʻia nā kiko o luna a me lalo.N/mm2 (MPa) ka wae o ka helu hua.ʻO ke kiko hua kiʻekiʻe (σsu): ke koʻikoʻi nui ma mua o ka hua ʻana o ka mea hoʻohālike a emi mua ka ikaika;ʻO ka helu haʻahaʻa haʻahaʻa (σsl): ke koʻikoʻi liʻiliʻi i ka manawa hāʻawi i ka wā i helu ʻole ʻia ka hopena transient mua.Kahi: Fs - ikaika hua (mau) o ka specimen i ka hoʻopaʻapaʻa, N (Newton) No laila - kumu kea-ʻāpana o ka specimen, mm2.
3.Elongation ma hope o ka haʻihaʻi: (σ) Ma ka hoʻāʻo tensile, ua kapa ʻia ka pākēneka o ka piʻi ʻana o ka lōʻihi o ke kikoʻī ma hope o ka huki ʻana i kona unahi i ka lōʻihi o ka unahi kumu.Hōʻike ʻia ma σ, ʻo ka ʻāpana he %.Kahi: L1 - ka lōʻihi o ka hōʻailona ma hope o ka huki ʻana o ke ʻano, mm;L0 - ka lōʻihi o ka pitch kumu o ka specimen, mm.
4.ʻO ka emi ʻana o ka hakina: (ψ) Ma ka hoʻāʻo ʻana, ʻo ka emi ʻana o ka ʻāpana keʻa i kona emi ʻana ma hope o ka huki ʻia ʻana o ka mea hoʻohālike ma ke ʻano he pākēneka o ka ʻāpana keʻa kumu i kapa ʻia ʻo ka hōʻemi fractional.Hōʻike ʻia e like me ψ, ma %.Kahi: S0 - ka ʻāpana keʻa mua o ka mea hoʻohālike, mm2;S1 - ka liʻiliʻi liʻiliʻi ʻāpana keʻa i ka emi ʻana ma hope o ka huki ʻia ʻana o ka specimen, mm2.
5.ʻO ka papa kuhikuhi paʻakikī: ka hiki i kahi mea metala ke pale aku i ka hoʻokomo ʻana o kahi mea paʻakikī i loko o ka ʻili, i kapa ʻia ʻo ka paʻakikī.Ma muli o ke ʻano hoʻāʻo a me ke ʻano o ka noi, hiki ke hoʻokaʻawale ʻia ka paʻakikī i Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, microhardness a me ke kiʻekiʻe wela paʻakikī.No ka mea, ua hoʻohana 'ia ka paipu ma Brinell, Rockwell, Vickers paakiki ekolu.
ʻO Brinell hardness (HB): Ke hoʻohana nei i ke kila a i ʻole carbide pōpō o kekahi anawaena, e kaomi i ka ikaika hoʻāʻo i ʻōlelo ʻia (F) i ka ʻili o ka specimen, e wehe i ka ikaika hoʻāʻo ma hope o ka manawa paʻa i ʻōlelo ʻia, a ana i ke anawaena indentation (L) ma ka ʻili o ka mea hoʻohālike.ʻO ka waiwai paʻakikī ʻo Brinell ka quotient i loaʻa ma ka puʻunaue ʻana i ka ikaika hoʻāʻo me ka ʻāpana spherical o ka indentation.Hōʻike ʻia e like me HBS (pōpō hao) ma N/mm2 (MPa).
Hoʻohana nui ʻia nā paipu kila wela wela i ke kūkulu ʻana, nā mīkini, ka ʻeli lanahu, ka ʻoihana kemika, ka mana uila, nā kaʻa kaʻaahi, nā ʻoihana kaʻa, nā alaloa, nā alahaka, nā ipu, nā hale haʻuki, nā mīkini mahiʻai, nā mīkini ʻaila, nā mīkini ʻimi a me nā ʻoihana hana ʻē aʻe. .
ʻO ka paipu kila Galvanized he paipu kila welded me kahi wela wela a i ʻole electro galvanized surface.Hiki i ka Galvanization ke hoʻonui i ka pale ʻana o nā paipu kila a hoʻolōʻihi i ke ola lawelawe.He nui ka hoʻohana ʻana o ka paipu kila Galvanized, ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he pipeline no nā wai haʻahaʻa haʻahaʻa e like me ka wai, ke kinoea a me ka ʻaila, hoʻohana ʻia ʻo ia ma ke ʻano he paipu aila a me ka paipu aila i loko o ka ʻoihana ʻaila, ʻoi aku ma ʻO nā māla aila moana, ma ke ʻano he mea hoʻomehana aila, condensation cooler a me ka distillation lanahu a me ka mea holoi holoi ʻaila no nā lako coking kemikal, a ma ke ʻano he paipu kākoʻo no nā puʻu paipu trestle a me nā lua mining, etc.
Paipu wai, paipu aila, paipu scaffolding, pa alanui, uhi hale, etc.
