ʻElua ʻano o nā mea e pili ana i ka maikaʻi o nā paipu ʻole: ʻoi aku ka maikaʻi o ke kila a me nā mea hana ʻōwili.

Kūkākūkā ʻia ma ʻaneʻi nā kumu he nui o ke kaʻina ʻōwili. ʻO nā mea hoʻoikaika nui: ka mahana, ka hoʻoponopono ʻana i ke kaʻina hana, ka maikaʻi o ka mea hana, ka hoʻomaʻamaʻa ʻana a me ka lubrication, ka wehe ʻana a me ka hoʻomalu ʻana i nā sundries ma ka ʻili o nā ʻāpana ʻōwili, etc.

1. Ka wela

ʻO ka mahana ka mea nui loa e pili ana i ka maikaʻi o nā paipu seamless. ʻO ka mea mua, ʻo ka like ʻole o ka wela wela o ka pahu blank e pili pono i ka mānoanoa o ka paia a me ka maikaʻi o ka ʻili o loko o ka capillary perforated, ka mea e pili ana i ka maikaʻi o ka mānoanoa pā o ka huahana. ʻO ka lua, ʻo ka pae wela a me ka like ʻole o ka paipu kila maʻemaʻe i ka wā o ka ʻōwili ʻana (ʻoi aku ka wela o ka ʻōwili hope ʻana) e pili ana i nā waiwai mechanical, ka pololei o ka dimensional a me ka maikaʻi o ka ʻili o ka huahana i hāʻawi ʻia i ka moku wela, ʻoi aku ka nui o ka billet a i ʻole. tube blank Ke hoʻomāhana ʻia a i ʻole ke puhi ʻana, e hoʻoulu ʻia nā huahana ʻōpala. No laila, i ke kaʻina hana o nā paipu seamless wela, pono e hana mua ka hoʻomehana ʻana a me ka mālama ʻana i ka mahana deformation e like me ke kaʻina hana.
2. Hoʻoponopono kaʻina hana
ʻO ka maikaʻi o ka hoʻoponopono kaʻina hana a me ka maikaʻi o ka hana e pili nui i ka geometric a me ka hiʻohiʻona maikaʻi o nā paipu kila ʻole.
ʻO kahi laʻana, ʻo ka hoʻoponopono ʻana o ka mīkini piercing a me ka wili wili e pili ana i ka pololei o ka mānoanoa o ka pā o ka huahana, a ʻo ka hoʻoponopono ʻana o ka mīkini sizing pili i ka pololei o waho a me ka pololei o ka huahana. Eia kekahi, pili ka hoʻoponopono kaʻina hana inā hiki ke hana maʻamau ke kaʻina hana.

3. Mea hana maikaʻi
Inā maikaʻi a maikaʻi ʻole paha ka maikaʻi o ka hāmeʻa, kūpaʻa a ʻaʻole paha, pili pono i ka pololei o ka dimensional, ka maikaʻi o ka ʻili a me ka hoʻohana pono ʻana o ka huahana; ʻO ka ʻili, ʻo ka lua e pili i ka hoʻohana ʻana i ka mandrel a me nā kumukūʻai hana.

4. Kaʻina hana hoʻoluʻu a lubrication
ʻAʻole pili wale ka maikaʻi ʻoluʻolu o nā plugs piercing a me nā ʻōwili i ko lākou ola, akā pili pū kekahi i ka mana maikaʻi o ka ʻaoʻao o loko a me waho o nā huahana i hoʻopau ʻia. ʻO ka maikaʻi ʻoluʻolu a me ka lubrication o ka mandrel e pili mua i ka maikaʻi o ka ʻili o loko, ka pololei o ka mānoanoa o ka paia a me ka hoʻohana ʻana i ka mandrel o ka paipu kila ʻole; i ka manawa like, e hoʻopili ia i ka ukana i ka wā o ka ʻōwili.

5. ʻO ka wehe ʻana a me ka mālama ʻana i nā haumia ma ka ʻili o ka ʻāpana i ʻōwili ʻia
E pili ana kēia i ka wehe pono ʻana o ka unahi oxide ma ka ʻaoʻao o loko a me waho o nā paipu capillary a me nā paipu paʻa ʻole a me ka hoʻomalu ʻana o ka re-oxidation ma mua o ka holo ʻana o ka deformation. ʻO ka puhi Nitrogen a me ka hoʻoulu ʻana i ka borax ma ka lua o loko o ka puʻupuʻu capillary, ka wai hoʻohaʻahaʻa kiʻekiʻe ma ka puka o ka paipu i ʻōwili ʻia a me ke anawaena paʻa (hōʻemi) hiki ke hoʻomaikaʻi maikaʻi a hoʻomaikaʻi i ka maikaʻi o ka ʻaoʻao o loko a me waho.

I ka pōkole, he nui nā kumu e pili ana i ka maikaʻi o nā paipu kila ʻole, a ʻo lākou ka hopena i hui pū ʻia o nā kumu like ʻole. No laila, pono e ho'omalu maika'i'ia nā mea ho'oikaika nui i'ōlelo'ia ma luna. Ma kēia ala wale nō e hiki ai iā mākou ke hoʻomalu i ka maikaʻi o nā paipu kila maʻemaʻeʻole a hana i nā puʻupuʻu kila wela wela me ka pololei kiʻekiʻe, ka hana maikaʻi a me ka maikaʻi maikaʻi.
