Hoʻokaʻawale ʻia nā paipu kila maʻemaʻe i ʻelua mau ʻāpana: ʻo nā paipu kila hoʻoheheʻe ʻia a me ke anuanu (huki).
ʻO ka paipu kila liʻiliʻi i ʻōwili ʻia(DIN2391 / EN10305) he paipu kila maʻemaʻe ʻole me ka pololei kiʻekiʻe a me ka hoʻopau ʻili maikaʻi i hoʻohana ʻia i nā hale mīkini a me nā mea hydraulic.Ma waho aʻe o nā paipu kila maʻamau, nā paipu kila haʻahaʻa a me ka haʻahaʻa haʻahaʻa, nā paipu kila kiʻekiʻe, nā paipu kila kila, nā paipu kila kuhiliʻole, nā paipu pohā ʻaila, a me nā paipu kila ʻē aʻe, ʻo nā paipu liʻiliʻi i hui pū ʻia me ka carbon thin. - nā paipu kila pā, nā paipu kila lahilahi me ka paia, nā paipu kila lahilahi, a me nā paipu kila kūikawā.ʻO ke anawaena o nā paipu kila liʻiliʻi liʻiliʻi hiki ke hiki i 6mm, hiki i ka mānoanoa o ka paia ke hiki i 0.25mm, a ʻo ke anawaena o waho o nā paipu lahilahi hiki ke hiki i 5mm, me ka mānoanoa o ka paia ma lalo o 0.25mm.ʻOi aku ka pololei o ke ana ʻana ma mua o ka ʻōwili wela.
ʻO nā paipu wela i ʻōwili ʻole ʻia ma ke ʻano he ʻoi aku ke anawaena o waho ma mua o 32mm a me ka mānoanoa pā o 2.5-75mm.Hoʻokaʻawale ʻia lākou i nā paipu kila maʻamau, nā paipu haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa, nā paipu kila kiʻekiʻe kiʻekiʻe, nā paipu kila kila, nā paipu kila kila, nā paipu māwae ʻaila, nā paipu kila geological, a me nā paipu kila ʻē aʻe.
ʻO nā mea i hoʻohana maʻamau ʻia no nā paipu liʻiliʻi ka mea nui: ʻo ke kila kila wela a i ʻole ka ʻōwili anuanu e like me ASE1010, S20C, S35C, S45C SCM440 SCM420 SCM32, ST35 ST37 ST45 ST52 E235 E215 E355 4130 414 414, etc. -ʻO ke kila kalapona e like me S35 ST37 ST52 E235 E355 ka mea i hoʻohana nui ʻia no nā pipeline lawe wai.Hoʻohana ʻia nā paipu seamless i hana ʻia me S45, 40Cr a me nā kila kalapona ʻē aʻe e hana i nā mea mīkini, e like me nā ʻāpana koʻikoʻi o nā kaʻa a me nā tractors.Hoʻohana pinepine ʻia nā paipu kila ʻole e hōʻoia i ka ikaika a me nā hoʻāʻo palahalaha.Hāʻawiʻia nā paipu kila i'ōwiliʻia i ka'ōwili wela a iʻole ka wela wela;Hāʻawi ʻia ka ʻōwili anuanu ma kahi kūlana i mālama ʻia i ka wela.
ʻO nā ʻokoʻa nui ma waena o nā paipu liʻiliʻi i ʻōwili ʻia a me ke anuanu:
1. Cold rolled formed steel e hiki ai ke hoʻopaʻa kūloko o ka ʻāpana keʻa, a laila hoʻohana piha i ka hiki ke amo o ka lālā ma hope o ke kuʻi ʻana;Eia naʻe, ʻaʻole ʻae ʻia nā ʻāpana kila wela e hana i ka buckling kūloko.
2. ʻO nā kumu o ke koena o ka hoʻoulu ʻana i ke koʻikoʻi i loko o nā ʻāpana kila wela a me ke anuanu, he ʻokoʻa nō hoʻi nā ʻokoʻa nui i ka puʻunaue ʻana i ke koʻikoʻi koena ma ka ʻāpana.ʻO ke koena koʻikoʻi puʻunaue ma luna o ke keʻa o ka anu-i hanaia lahilahi-pā pōhaku curved, oiai ke koena koʻikoʻi puunaue ma ke kea o ka wela-owili a welded kila mea lahilahi.
3. Ua oi aku ka oolea torsional kuokoa o ke kila pauku wela ma mua o ke kila o ka pauku anuanu, no laila, oi aku ka maikai o ke ku'e ana o ke kila pauku wela ma mua o ke kila.
ʻO ka New Gapower Metal he mea hanaʻoihana o ka paipu kila hydraulic.Me ka hana makahiki o 10,000 tons o ke kiʻekiʻe kiʻekiʻe seamless paipu kila a me 20,000 ton paipu kila a me ka pahu kila.
