Ua hoʻopōʻaiapuni ʻia ka paipu kila humuhumu e ke kila poepoe holoʻokoʻa, a ʻo ka paipu kila me ka ʻole o ka weld ma ka ʻili ua kapa ʻia ʻo ka paipu kila humuhumu. Wahi a ke ʻano hana, hiki ke hoʻokaʻawale ʻia ka paipu kila humuhumu i ka paipu kila humuhumu wela, ka paipu kila humuhumu anu, ka paipu kila humuhumu anu, ka paipu kila humuhumu extruded, ka paipu jacking a pēlā aku. Wahi a ke ʻano o ka ʻāpana, ua māhele ʻia ka paipu kila humuhumu i ʻelua ʻano: poepoe a me ke ʻano. ʻO ke anawaena kiʻekiʻe he 900mm a ʻo ke anawaena liʻiliʻi he 4mm. Wahi a nā hoʻohana like ʻole, aia nā paipu kila humuhumu paia mānoanoa a me nā paipu kila humuhumu paia lahilahi. Hoʻohana nui ʻia ka paipu kila humuhumu no ka paipu ʻeli honua petroleum, petrochemicalpaipu haki, paipu paila, paipu hali a mepaipu kila kūkulu kiʻekiʻeno nā kaʻa, nā tractors a me nā mokulele. 

Wahi a ka hoʻohana ʻana, ua māhele ʻia i ʻelua mau ʻāpana i ke kumu laulā (no ka wai, nā paipu kinoea a me nā ʻāpana kūkulu, nā ʻāpana mechanical) a me nā mea kūikawā (no nā paila, ka ʻimi honua, nā bearings, ke kūpaʻa waikawa, a me nā mea ʻē aʻe).

ʻO ka paipu kila humuhumu maʻamau i ʻōwili ʻia e ke kila kila kalapona maʻamau, ke kila kila haʻahaʻa haʻahaʻa a i ʻole ke kila kila, a ʻo ia ka hopena nui loa, hoʻohana nui ʻia ma ke ʻano he paipu a i ʻole ʻāpana kūkulu no ka lawe ʻana i nā wai. Nui nā ʻano paipu humuhumu no nā kumu kūikawā, e like me nā paipu humuhumu paila, nā paipu mana kemika, nā paipu humuhumu geological a me nā paipu humuhumu petroleum. Loaʻa i ka paipu kila humuhumu kahi ʻāpana hakahaka a hoʻohana nui ʻia ma ke ʻano he paipu no ka lawe ʻana i nā wai, e like me nā paipu no ka lawe ʻana i ka ʻaila, ke kinoea kūlohelohe, ke kinoea, ka wai a me kekahi mau mea paʻa.

Kaʻina hana hana paipu kila humuhumu:

① Ke kaʻina hana nui o ka paipu kila wili ʻole i ʻōwili wela ʻia (△ Ke kaʻina hana nānā nui): 

Hoʻomākaukau a me ka nānā ʻana △→ Hoʻomehana → perforating → ʻŌwili → hoʻomehana hou → Sizing → Lapaʻau wela △→ Hoʻopololei → Hoʻopau → Nānā △ (ʻaʻole luku, kino a me ke kemika, nānā papa) → mālama

② ʻO ke kaʻina hana nui o ka paipu kila wili anu (i huki ʻia):

Hoʻomākaukau hakahaka → lubrication pickling → ʻŌwili anu (kaha kiʻi) → Lapaʻau wela → hoʻopololei → hoʻopau → nānā

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana hana paipu kila humuhumu maʻamau i ʻelua ʻano: ke kaha kiʻi anu a me ka ʻōwili wela. ʻOi aku ka paʻakikī o ke kaʻina hana hana paipu kila humuhumu anu ma mua o ka ʻōwili wela. ʻO ka paipu billet mua e hana i ʻekolu ʻōwili mau, extrusion ma hope o ka hoʻāʻo nui ʻana, inā ʻaʻole pane ka ʻili i ka māwae ma hope o ka ʻoki ʻana o ka paipu poepoe e ka mīkini ʻoki, ʻoki ʻia ka ulu ʻana o hoʻokahi mika hakahaka. A laila e hoʻokomo i ke kaʻina hana annealing, annealing me ka pickling wai waikawa, pono e hoʻolohe ka pickling inā he nui nā pehu ma ka ʻili. Inā he nui nā pehu, e hōʻike ana ʻaʻole hiki i ka maikaʻi o ka paipu kila ke hoʻokō i nā kūlana kūpono. ʻOi aku ka pōkole o ke ʻano o ka paipu kila humuhumu anu ma mua o ka paipu kila humuhumu wela, ʻoi aku ka liʻiliʻi o ka mānoanoa o ka paia o ka paipu kila humuhumu anu ma mua o ka paipu kila humuhumu wela, akā ʻoi aku ka mālamalama o ka ʻili ma mua o ka paipu kila humuhumu paia mānoanoa, ʻaʻole ʻino loa ka ʻili, a ʻaʻole nui ka burr o ke caliber.

ʻO ke kūlana hoʻouna o ka paipu kila wili ʻole i ʻōwili wela ʻia ma hope o ka mālama wela ʻana. Ma hope o ka nānā ʻana i ka maikaʻi o ka paipu kila wili ʻole i ʻōwili wela ʻia, pono e nānā pono ʻia ke koho lima koʻikoʻi a nā limahana, a laila e nānā pono i ka ʻaila ʻili, a laila e ukali ʻia e kekahi mau hoʻokolohua kaha kiʻi anu, a laila e hoʻāʻo i ka perforation inā nui loa ka perforation e hoʻopololei ʻia. Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia i ka mīkini ʻike kīnā e ka mea hoʻouna no ka hoʻokolohua ʻike kīnā, a laila e kau inoa ʻia, hoʻonohonoho ʻia a waiho ʻia i loko o ka hale kūʻai.

ʻO ka paipu poepoe hakahaka → hoʻomehana → perforation → ʻōwili skew ʻekolu-ʻōwili, ʻōwili mau a i ʻole extrusion → Wehe ʻana → ana (a i ʻole hōʻemi) → Hoʻomaʻalili → hoʻopololei → hoʻāʻo kaomi wai (a i ʻole nānā) → Māka → ʻO ka paipu kila humuhumu i ka mālama ʻana ua hana ʻia me ka ingot kila a i ʻole ka paipu paʻa hakahaka ma o ka perforation e hana i ka paipu capillary, a laila ʻōwili wela, ʻōwili anu a i ʻole ke kahakiʻi anu. Hōʻike ʻia nā kikoʻī o ka paipu kila humuhumu e ke anawaena waho * ka mānoanoa o ka paia o millimeters.

ʻOi aku ka nui o ke anawaena o waho o ka paipu wili wela ma mua o 32mm, ʻo ka mānoanoa o ka paia he 2.5-200mm, ʻo ke anawaena o waho o ka paipu kila wili anu hiki ke 6mm, ʻo ka mānoanoa o ka paia hiki ke 0.25mm, ʻo ke anawaena o waho o ka paipu lahilahi hiki ke 5mm, ʻoi aku ka mānoanoa o ka paia ma mua o 0.25mm, a ʻoi aku ka pololei o ka nui ma mua o ka paipu wili wela.
