ʻO ka paipu kila humuhumu ʻole he ʻano paipu kila humuhumu ʻole, a ʻoi aku ka kiʻekiʻe o kāna hana ma mua o ka paipu kila humuhumu maʻamau, no ka mea, ʻoi aku ka nui o ka Cr i loko o kēia paipu kila, a ʻoi aku ka maikaʻi o kona kūpaʻa wela kiʻekiʻe, kūpaʻa wela haʻahaʻa a me ka hana kūpaʻa i ka palaho ma mua o nā paipu kila humuhumu ʻē aʻe. ʻAʻole hiki ke hoʻohālikelike ʻia, no laila hoʻohana nui ʻia nā paipu kila i ka petroleum, kemika, ka mana uila, ka paila a me nā ʻoihana ʻē aʻe. Loaʻa i ka paipu kila humuhumu ʻole (Seamless Steel Tube) kahi ʻāpana hakahaka, kahi ʻāpana kila lōʻihi me nā hui ʻole a puni. Loaʻa i ka paipu kila kahi ʻāpana hakahaka a hoʻohana nui ʻia e like me ka pipeline no ka lawe ʻana i nā wai, e like me nā pipelines no ka lawe ʻana i ka ʻaila, ke kinoea kūlohelohe, ke kinoea, ka wai a me kekahi mau mea paʻa. Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻo ka paipu kila humuhumu ʻole he like ka ikaika flexural a me ka torsional a me ke kaumaha māmā. He kila ʻāpana hoʻokele waiwai ia a hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana kūkulu a me nā ʻāpana mechanical, e like me ka lawe ʻana i ka ʻaila. ʻO ka hana ʻana i nā ʻāpana apo me ka paipu kila humuhumu ʻole hiki ke hoʻomaikaʻi i ka helu hoʻohana o nā mea, hoʻomaʻalahi i ke kaʻina hana, mālama i nā mea a me ka manawa hana, e like me nā apo bearing rolling, jack sets, etc., i hoʻohana nui ʻia i ka hana ʻana i nā paipu kila. ʻO ka paipu kila humuhumu ʻole he mea pono ʻole no nā mea kaua maʻamau like ʻole, a ʻo ka pahu, ka pahu, a me nā mea ʻē aʻe, pono e hana ʻia me ka paipu kila. Eia kekahi, i ka wā e kau ʻia ai ka ʻāpana apo i ke kaomi radial i loko a i waho paha, ua like ka ikaika. No laila, ʻo ka hapa nui o nā paipu kila humuhumu ʻole he mau paipu poepoe.

Paipu kila humuhumu kūkuluHoʻohana nui ʻia no ke ʻano maʻamau a me ke ʻano mechanical. ʻO kāna mea e hōʻike ana (brand): kila kalapona 20, kila 45; kila hui Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.
Nā paipu kila humuhumu ʻole no ka lawe ʻana i nā wai: hoʻohana nui ʻia no ka lawe ʻana i nā paipu wai i ka ʻenekinia a me nā lako nui. ʻO ka mea i koho ʻia (papa) he 20, Q345, a pēlā aku.
Nā paipu kila humuhumu ʻole no nā paila haʻahaʻa a me ke kaumaha: hoʻohana nui ʻia no nā paipu no ka lawe ʻana i nā wai haʻahaʻa a me ke kaumaha waena i nā paila ʻoihana a me nā paila kūloko. ʻO ka mea i koho ʻia he 10, 20 kila.
Nā paipu kila humuhumu no nā paila kiʻekiʻe: hoʻohana nui ʻia no nā poʻomanaʻo a me nā paipu o ka wai lawe wela kiʻekiʻe a me ke kaomi kiʻekiʻe ma nā paila i nā hale hana mana a me nā hale hana mana nukelea. ʻO nā mea i koho ʻia he 20G, 12Cr1MoVG, 15CrMoG, a pēlā aku.
Nā paipu kila humuhumu no nā lako mea hoʻomomona kiʻekiʻe: hoʻohana nui ʻia no nā paipu wai wela kiʻekiʻe a me ke kaomi kiʻekiʻe ma nā lako mea hoʻouluulu. ʻO nā mea i koho ʻia he 20, 16Mn, 12CrMo, 12Cr2Mo, etc.
Nā paipu kila humuhumu no ka haki ʻaila: hoʻohana nui ʻia i nā paila, nā mea hoʻololi wela a me kā lākou mau paipu wai hoʻoili i nā mea hoʻoheheʻe aila. ʻO kāna mau mea hana he 20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, etc.
ʻO nā paipu kila humuhumu ʻole no nā pahu kinoea: hoʻohana nui ʻia e hana i nā pahu kinoea a me nā pahu hydraulic like ʻole. ʻO kāna mau mea hana e hōʻike ana he 37Mn, 34Mn2V, 35CrMo a pēlā aku.
ʻO nā paipu kila wili ʻole i ʻōwili wela ʻia no nā mea hoʻopaʻa hydraulic: hoʻohana nui ʻia no ka hana ʻana i nā kākoʻo hydraulic, nā cylinders a me nā kolamu i loko o nā lua lanahu, a me nā cylinders hydraulic ʻē aʻe a me nā kolamu. ʻO kāna mau mea i koho ʻia he 20, 45, 27SiMn, a pēlā aku.
Paipu kila wili ʻole i huki anu ʻia a ʻōwili anu ʻia paha: hoʻohana nui ʻia no ke kūkulu mīkini, nā lako kaomi kalapona, e koi ana i ka pololei kiʻekiʻe a me ka hoʻopau ʻili maikaʻi. ʻO kāna mea e hōʻike ana he 20, 45 kila, a pēlā aku.
