Hana ʻia ka paipu kila humuhumu ma ka hoʻowali ʻana i ke kila poepoe holoʻokoʻa, a ʻo ka paipu kila me ka ʻole o ka humuhumu wili ma ka ʻili ua kapa ʻia ʻo ia he paipu kila humuhumu. Wahi a ke ʻano hana, hiki ke hoʻokaʻawale ʻia nā paipu kila humuhumu i nā paipu kila humuhumu wela, nā paipu kila humuhumu anu, nā paipu kila humuhumu anu, nā paipu kila humuhumu extruded, a me ka paipu jacking. Wahi a ke ʻano ʻokiʻoki, ua hoʻokaʻawale ʻia nā paipu kila humuhumu i ʻelua ʻano: poepoe a me ke ʻano kūikawā, a he ʻano paʻakikī nā paipu ʻano kūikawā e like me nā paipu huinahā, oval, triangular, hexagonal, melon-shaped, star-shaped, a me nā paipu finned. ʻO ke anawaena kiʻekiʻe loa a hiki i 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 nā paipu kila humuhumu e like me nā paipu wili geological petroleum, nā paipu haki no ka ʻoihana petrochemical, nā paipu paila, nā paipu hali, a me nā paipu kila kūkulu kiʻekiʻe no nā kaʻa, nā tractors, a me ka mokulele.

He paipu kila i wili ʻole ʻia ma ke anawaena o kona ʻāpana kea. Wahi a nā ʻano hana like ʻole, ua māhele ʻia i loko o ka paipu ʻōwili wela, ka paipu ʻōwili anu, ka paipu huki anu, ka paipu i hoʻopuka ʻia, ka hoʻopili ʻana i ka paipu, a pēlā aku, nona nā lula hana ponoʻī.

ʻO nā mea hana e komo pū ana me ke kila kila kalapona maʻamau a me ke kiʻekiʻe, ke kila metala haʻahaʻa, ke kila metala, a pēlā aku.

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

ʻOi aku ka nui o ke anawaena o waho o ka paipu wili wela ma mua o 32mm, a ʻo ka mānoanoa o ka paia he 2.5-200mm. Hiki i ke anawaena o waho o ka paipu kila wili anu ke hiki i ka 6mm, a hiki i ka mānoanoa o ka paia ke hiki i ka 0.25mm. ʻOi aku ka pololei o ka ʻōwili ʻana ma mua o ka ʻōwili wela. Ma ke ʻano laulā, hana ʻia nā paipu kila wili ʻole me 10, 20, a me nā mea ʻē aʻe, nā kila kūkulu alloy.P5, P9, P11, P22, P91, P92, 15mog, 20mog, 12crmog, 15crmog, 12cr2mog, 12crmovg, a pēlā aku. o.10, 20a me nā mea ʻē aʻenā paipu humuhumu kila kalapona haʻahaʻahoʻohana nui ʻia no nā paipu lawe wai. Ma ke ʻano laulā, hoʻohana ʻia nā paipu kila humuhumu e hōʻoia i ka ikaika a me nā hoʻāʻo palahalaha. Hāʻawi ʻia nā paipu kila ʻōwili wela i kahi mokuʻāina ʻōwili wela a i ʻole i mālama ʻia i ka wela; hāʻawi ʻia nā paipu kila ʻōwili anu i kahi mokuʻāina mālama wela.
