Ke kūʻai aku nei i nā mea kūʻai aku i ke anawaena nui
ʻO ka paipu kila kila ke ʻano o ke kila a puni ka lōʻihi, i hoʻohana nui ʻia i nā pipeline hoʻoili ʻoihana e like me ka petroleum, ka ʻoihana kemika, ka lāʻau lapaʻau, ka meaʻai, ka ʻoihana māmā, nā mea hana mechanical a me nā mea hana mechanical. Eia kekahi, i ka wā e like ai ke kulou a me ka ikaika torsional, māmā ke kaumaha, no laila hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mechanical a me nā hale ʻenekinia. Hoʻohana pinepine ʻia ʻo ia e like me nā lako, lako kīhini, etc.
Hoʻohana mau ʻia nā ʻōlelo kuhikuhi paʻakikī ʻo Brinell, Rockwell a me Vickers e ana i ka paʻakikī o nā paipu kila kila.
ʻO ka paʻakikī ʻo Brinell ka maʻamau i hoʻohana nui ʻia no ka paipu kila kila. Hoʻohana pinepine ʻia ke anawaena indentation e hōʻike i ka paʻakikī o ka mea, he intuitive a maʻalahi. Eia naʻe, ʻaʻole ia e pili i nā paipu kila me ke kila paʻakikī a lahilahi paha.
ʻO ka hoʻāʻo paʻakikī ʻo Rockwell o ka paipu kila kila me ka hoʻāʻo paʻakikī Brinell, ʻo ia ke ʻano hoʻāʻo indentation. ʻO ka ʻokoʻa, ʻo ia ke ana i ka hohonu o ka indentation. ʻO ka hoʻāʻo paʻakikī ʻo Rockwell kahi hana i hoʻohana nui ʻia, ʻo ia ka lua o ka HRC ma mua o Brinell hardness Hb i nā kūlana paipu kila. Hiki ke hoʻohana ʻia ka paʻakikī Rockwell e ana i nā mea metala mai ka palupalu a i ka paʻakikī loa. Hoʻopau ia i ka hemahema o ke ʻano Brinell. ʻOi aku ka maʻalahi ma mua o ke ʻano Brinell a hiki ke heluhelu pololei i ka waiwai paʻakikī mai ke kelepona o ka mīkini paʻakikī. Eia naʻe, ma muli o kona liʻiliʻi liʻiliʻi, ʻaʻole pololei ka waiwai paʻakikī e like me ke ʻano Brinell.
ʻO ka hoʻāʻo paʻakikī ʻo Vickers o ka paipu kila kila he ʻano hoʻāʻo indentation, hiki ke hoʻohana ʻia no ka hoʻoholo ʻana i ka paʻakikī o nā mea metala lahilahi a me nā papa o luna. Loaʻa iā ia nā pōmaikaʻi nui o nā ʻano Brinell a me Rockwell a lanakila i kā lākou mau hemahema kumu, akā ʻaʻole maʻalahi ia e like me ke ʻano Rockwell. ʻAʻole hoʻohana ʻia ke ʻano Vickers i nā kūlana paipu kila.
Hiki ke hoʻohana ʻia ʻo W-b75 Vickers hardness tester no nā paipu kila kila i hoʻopili ʻia me ke anawaena o loko o ʻoi aku ma mua o 6.0mm a me ka mānoanoa o ka pā ma lalo o 13mm. He wikiwiki loa a maʻalahi hoʻi, a kūpono no ka nānā ʻana i ka hoʻomaʻamaʻa wikiwiki a me ka nondestructive o nā paipu kila kila. No nā paipu kila kila me ke anawaena o loko i ʻoi aku ma mua o 30mm a ʻoi aku ka mānoanoa o ka paia ma mua o 1.2mm, e hoʻohana ʻia ka mea hoʻāʻo paʻakikī ʻo Rockwell e hoʻāʻo i ka paʻakikī HRB a me HRC. No nā paipu kila kila me ke anawaena o loko ʻoi aku ka nui ma mua o 30mm a me ka mānoanoa o ka paia ma lalo o 1.2mm, e hoʻohana ʻia ka mea hōʻike paʻakikī ʻo Rockwell no ka hoʻāʻo ʻana i ka HRT a i ʻole hrn paʻakikī. No nā paipu kila kila me ke anawaena o loko ma lalo o 0mm a ʻoi aku ka nui ma mua o 4.8mm, e hoʻohana i ka mea hōʻike paʻakikī Rockwell kūikawā no nā paipu e hoʻāʻo ai i ka paʻakikī hr15t. Ke ʻoi aku ka nui o ke anawaena o ka paipu kila kila ma mua o 26mm, hiki ke hoʻohana ʻia ʻo Rockwell a i ʻole ka papa Rockwell hardness tester e hoʻāʻo ai i ka paʻakikī o ka paia o loko o ka paipu.
Hoʻokaʻawale ʻia nā paipu kila kila i nā paipu kila kalapona maʻamau, nā paipu kila kila kila kiʻekiʻe, nā paipu hoʻohuihui, nā paipu kila kila, nā paipu kila, nā paipu kila kila, nā paipu hui bimetallic, nā paipu i uhi ʻia a i uhi ʻia e mālama i nā metala makamae a hālāwai kūikawā. koi. Loaʻa i nā paipu kila kila nā ʻano like ʻole, nā hoʻohana like ʻole, nā koi ʻenehana like ʻole a me nā ʻano hana like ʻole. I kēia manawa, ʻo ke anawaena o waho o nā paipu kila he 0.1-4500mm a he 0.01-250mm ka mānoanoa o ka pā. I mea e hoʻokaʻawale ai i kona mau hiʻohiʻona, hoʻokaʻawale pinepine ʻia nā paipu kila e like me kēia mau ʻano.
Hiki ke hoʻokaʻawale ʻia ka paipu kila kila i ka paipu seamless a me ka paipu welded e like me ke ʻano hana. Hiki ke hoʻokaʻawale ʻia ka paipu kila maʻemaʻe i loko o ka paipu wela, ka paipu anu, ka paipu huki anu a me ka paipu extruded. ʻO ke kaha kiʻi anu a me ka ʻōwili anu ka hana lua o ka paipu kila; Hoʻokaʻawale ʻia ka paipu welded i ka paipu wili wili pololei a me ka paipu wiliwili spiral.
Hiki ke hoʻokaʻawale ʻia ka paipu kila kila i loko o ka paipu poepoe a me ka paipu ʻano kūikawā e like me ke ʻano cross-sectional. ʻO nā paipu ʻano kūikawā, nā paipu rectangular, nā paipu rhombic, nā paipu elliptical, nā paipu hexagonal, nā paipu octagonal a me nā paipu asymmetric cross-section. Hoʻohana nui ʻia ka paipu ʻano kūikawā i nā ʻāpana like ʻole, nā mea hana a me nā ʻāpana mechanical. Ke hoʻohālikelike ʻia me ka paipu pōʻai, ʻo ka paipu ʻano kūikawā maʻamau he manawa nui o ka inertia a me ka modulus pauku, a he nui ke kuʻekuʻe ʻana a me ke kūpaʻa ʻana, hiki ke hōʻemi nui i ke kaumaha o ke kino a mālama i ke kila.
Hiki ke hoʻokaʻawale ʻia ka paipu kila kila i ka paipu pauku like a me ka paipu ʻāpana ʻokoʻa e like me ke ʻano o ka profile. ʻO nā paipu ʻāpana like ʻole me nā paipu conical, nā paipu paepae a me nā paipu ʻāpana manawa.
Hiki ke hoʻokaʻawale ʻia ka paipu kila kila i loko o ka paipu maʻemaʻe a me ka pipe threaded (threaded steel pipe) e like me ke kūlana o ka hopena paipu. Hiki ke hoʻokaʻawale ʻia ka paipu threading i ka paipu threading maʻamau (pipe no ka lawe ʻana i ke kaomi haʻahaʻa e like me ka wai a me ke kinoea, i hoʻopili ʻia e ka cylindrical maʻamau a i ʻole conical pipe thread) a me ka pipe threaded kūikawā (pipe no ka petroleum a me ka wili geological, i hoʻopili ʻia e nā mea kūikawā. milo no ka paipu milo nui). No kekahi mau paipu kūikawā, i mea e hoʻopaʻa ai i ka hopena o ka milo i ka ikaika o ka hopena paipu, ka mānoanoa o ka hopena (ka mānoanoa o loko Ka mānoanoa waho a i ʻole ka mānoanoa o loko a me waho).
E like me ke kumu, hiki ke hoʻokaʻawale ʻia i loko o ka ʻaila punawai paipu (casing, oil pipe a drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure). paipu momona, paipu pohā ʻaila) a me ka paipu kai.
