Paipu lauwili ʻoleua hana ʻia mai nā pahu pahu o nā kikoʻī like ʻole ma o ka extrusion kiʻekiʻe-mehana, hoʻoluʻu, annealing, hoʻopau a me nā kaʻina hana ʻē aʻe. ʻO ia kekahi o nā ʻano kila hana nui ʻehā ma koʻu ʻāina. Hoʻohana nui ia no ka lawe ʻana i nā wai e like me ka wai, ka aila, ke kinoea maoli, ka lanahu, a me nā mea ʻē aʻe a no nā paipu i nā hale kūkulu. Hiki ke hoʻohana ʻia no ka hana ʻana i nā hale kalapona i nā ʻāpana ʻoihana koʻikoʻi e like me nā kaʻa, nā tractors, nā mea hydraulic, a me nā mīkini mining. ʻO nā paipu a me nā paipu hoʻohuihui. Hoʻohana nui ʻia nā paipu kila seamless i ka ʻaila, ʻoihana kemika, mana uila, kūkulu moku, aerospace, ʻoihana nuklea, kūkulu pale aupuni a me nā māla ʻē aʻe. Loaʻa i ka paipu kila maʻemaʻe kahi ʻāpana hakahaka, hiki ke hōʻemi i ka hui ʻana o ka mea, e hōʻemi ai i ka friction; i ka manawa like, he maikaʻi ka thermal conductivity a me ka thermal conductivity, no laila ua hoʻohana nui ʻia i ka hana ʻana i nā kaʻa, nā tractors, nā mea hydraulic, nā mīkini hana, a me nā mea ʻē aʻe.

1. Hiki ke hana ʻia nā paipu seamless e like me nā koi like ʻole a hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical.

No ka laʻana, ʻo nā ʻenekini kaʻa a me nā ʻōnaehana hoʻoili he mau ʻāpana kikoʻī kiʻekiʻe me nā kumu kūikawā. Pono lākou i ka pololei maikaʻi e hoʻokō i nā koi hoʻolālā. I ka ʻoihana kaʻa, hoʻopilikia pinepine ʻia nā mea hoʻokele kaʻa e nā kūlana hana paʻakikī. ʻO ka maikaʻi o ka'ōnaehana hoʻokele e pono ai ka pololei kiʻekiʻe. No laila, paʻakikī loa ka hana ʻana o ia mau ʻāpana kiʻekiʻe. Ma hope o nā makahiki o ka hoʻomohala ʻana, hiki i ko mākou ʻāina ke hana i nā paipu kila maʻemaʻe kiʻekiʻe.

2. Hiki ke hoʻokaʻawaleʻia nāʻano hana hana o nā paipu liʻiliʻi i loko o nā paipu kila wela, ke anu a iʻole ke anu (extruded), hiki ke hanaʻia i nā lōʻihi kūpono e like me ka makemake o ka mea hoʻohana.

Hiki ke hoʻokaʻawale ʻia nā mea waiwai i: nā paipu kila kila, ke kila kila a i ʻole ke kila kila, ke keleawe a me nā paipu metala metala ʻole ʻē aʻe a me nā paipu kila kila ʻole; e like me nā hoʻohana like ʻole, hiki ke hoʻokaʻawale hou ʻia i loko o: nā paipu hoʻoheheʻe ʻaila, ka lawe ʻana i nā paipu wai, nā paipu kila kemika, nā paipu kila structural, nā paipu paila kīʻaha kiʻekiʻe a me nā paipu kila seamless kūikawā i hana ʻia i nā mea waiwai ʻole a i ʻole nā ​​mea kila, etc. ʻO ka pae wela hana o 20 # seamless steel pipe ma waena o -40 ~ 350 ℃; e like me kona haku mele 'ana, hiki ke maheleia i amorphous carbon structural paipu blank a olokaa seamless poepoe paipu. ʻO nā ʻano ʻano like ʻole o nā paipu poepoe ʻole: nā paipu hana kalapona (e like me nā paipu ʻaila hinu, nā pahu hoʻoili kaʻa, a me nā mea ʻē aʻe). nā paipu, a me nā mea'ē aʻe), nā paipu kila haʻahaʻa a me nā paipu kila kūikawā. Na paipu kila, a pela aku; e like me ka haku mele ʻana, hiki ke hoʻokaʻawale ʻia i loko o nā paipu kila seamless acid-resistant; e like me ke ʻano a me ka nui, hiki ke hoʻokaʻawale ʻia i loko o nā paipu square, nā puʻupuʻu poepoe, nā ʻāpana ʻāpana ʻāpana, a me nā paipu kūikawā.

Ua nāwaliwali ka makemake o ka mākeke no nā paipu kila ʻole. Ma ke ʻano o ka waihona waiwai: ke hoʻopau koke nei nā hale kila kila, akā aia kekahi ʻano kaomi waiwai. Eia kekahi, ma muli o ka hopena o ka mālama ʻana i ke kaiapuni a me nā kulekele palena hana, ʻaʻole koʻikoʻi ka kūʻē ʻana ma waena o ka hoʻolako mākeke a me ka noi, a ua kaupalena ʻia ka lumi no ka piʻi ʻana o ke kumukūʻai.

3. Hiki ke hana ʻia nā paipu seamless e ka ʻōwili wela a i ʻole ke kiʻi anuanu a laila welded.

I ka hoʻohana ʻana i nā paipu kila seamless no ka hana mechanical, pono e hana ʻia e like me nā kikoʻī, nā ana, nā ʻano a me nā mea i kuhikuhi ʻia i nā kaha kiʻi, a pono e hoʻokō ʻia ka mālama ʻana i luna e like me nā lula ma mua o ke kuʻi ʻana. ʻAʻole ʻae ʻia ka wiliwili pololei. Hiki ke hoʻoheheʻe ʻia ka metala weld a hoʻemi i ka maikaʻi o ka weld i ka wela i hana ʻia inā nui ka wela. Ma mua o ka welding, pono e nānā pono ʻia ka maikaʻi o ka weld a pono e hoʻokō ʻia ka hoʻāʻo ʻole. Ke loaʻa nā hemahema ma nā welds, ʻaʻole ʻae ʻia ka nānā ʻana i nā hemahema a pono e hoʻohana ʻia nā mea hoʻāʻo ʻino ʻole; i ka wā e mau ana nā hemahema ma nā welds, ʻaʻole ʻae ʻia ka nānā ʻana i nā hemahema; inā mau nā māwae ma nā welds, ʻaʻole ʻae ʻia ka nānā ʻana i nā hemahema; i ka wā e mau ana nā māwae ma nā welds ʻAʻole ʻae ʻia ka nānā ʻana i nā hemahema. Ke hiki mai nā hemahema koʻikoʻi, pono e hoʻōki koke i ka wiliwili a pono e hoʻoponopono i ka wiliwili.
