    Ke hana nui nei kā mākou hui i ka ʻoihana kūʻai aku o nā paipu kila ʻole,Paipu kila Kina, SMLS pake, Paipu kila maʻemaʻe, ʻO nā paipu kila ʻole, SMLS, SMLS Kina, Nā paipu hale SMLS.

    Nui nā kumu hoʻohālike o ka hana ʻana i ka paipu kila maʻemaʻe
    1, ʻO nā paipu kila ʻōwili wela

    lilo i kumu hoʻohālike no ka hana ʻana i ka paipu kila ʻole. Nui-kū hoʻomau ʻenehana ʻolokaʻa paipu.
    Ke hoʻohālikelike ʻia me nā hiʻohiʻona ʻē aʻe, ua lilo ka wili wili mau i koho mua no nā ʻoihana hana hoʻoheheʻe kila seamless nui o ka honua ma muli o kona kūlana kiʻekiʻe, kiʻekiʻe kiʻekiʻe, kiʻekiʻe ka pono, a me ka hoʻohana haʻahaʻa.
    2, 3 wili paipu wili mau

    ua wehe i kahi au hou o ka ʻenehana paipu kila hoʻomau
    Mai ka makahiki 2005, ua ʻoi aku ma mua o 20 mau pūʻulu o nā wili wili mau 3-roll i kūkulu ʻia a ke kūkulu ʻia nei ma ka honua holoʻokoʻa. ʻO ke kūkulu ʻia ʻana o kēia mau wili wili i hana i kahi au hou o 3-roll mau ʻenehana paipu kila.
    3. ʻO ka mīkini wili paipu ʻakomi, ʻike ʻia ʻo Plug mill
    Ma waena o lākou, nui ka nui a me ka nui o ka nui a me ka nui o ka nui o ka paipu wili wili i mea nui ma hope o ka hoʻololi ʻenehana.
    4. ʻO ka wili paipu manawa, ʻike ʻia ʻo Pilger mill

    He kūpono ia no ka hana ʻana i nā paipu kila nui a me ka mānoanoa a me ka manoanoa. ʻO ia kekahi o nā hiʻohiʻona kahiko loa o ka honua
    Ma muli o ka haʻahaʻa haʻahaʻa o ka hana a me ka maikaʻi ʻole o ka ʻili o waho o kēia wili, paʻakikī kona kumukūʻai hana a me ka maikaʻi o ka huahana e hoʻokūkū me nā wili ʻē aʻe. Ua hoʻopau ʻia ka hapa nui o nā wili liʻiliʻi a me waena. Loaʻa ka pono i ka hana ʻana i nā paipu kila mānoanoa nui, ʻoi aku hoʻi no ka hana ʻana i nā paipu mana o ka pā nui. He ʻano hana maikaʻi nō nā wili wili paipu manawa, no laila e mālama ʻia.
    5.ʻO ka mīkini wili paipu pololei, 3-roll tube rolling machine
    Ua kapa ʻia ka mīkini ʻōwili pahu pololei ʻo Accu2Roll tube rolling machine, a ʻo ka 3-roll tube rolling machine i kapa ʻia ʻo Assel tube rolling machine. ʻO ia hoʻi ka mea wili kila paipu ʻole me ka pololei o ka ʻōwili kiʻekiʻe. ʻO ka hoʻonohonoho ʻana o nā kaʻina hana i mua a i hope ua like like me ka Accu2Roll tube mill koe wale nō ka hoʻohana ʻana o ka stretcher i 3-roll cross-rolling.
    6. Nā mīkini ʻōwili paipu ʻē aʻe
    Ma waho aʻe o Kina, ʻo nā mea hoʻokuke, nā mīkini hoʻoheheʻe paipu nui, a me nā mīkini skew nui a me nā mīkini hoʻonui ʻaʻole i ulu hou i nā ʻāina ʻē aʻe o ka honua. Ma Kina, ma muli o ka hoʻomohala wikiwiki ʻana o ka hana ʻana i ka paipu kila maʻemaʻe a me ke koi ʻana i nā huahana kiʻekiʻe, ua hana hou ka hana ʻana i kēia mau wili wili.

    Welina mai e kipa i kā mākou hui, hale hana kahi e hōʻike ai i nā huahana like ʻole e hoʻokō i kāu manaʻo. I kēia manawa, kūpono ke kipa ʻana i kā mākou pūnaewele, a e hoʻāʻo kā mākou limahana kūʻai i kā lākou mea maikaʻi loa e hāʻawi iā ʻoe i ka lawelawe maikaʻi loa. E ʻoluʻolu e kelepona mai iā mākou inā makemake ʻoe i ʻike hou aku. ʻO kā mākou pahuhopu ke kōkua i nā mea kūʻai aku e hoʻomaopopo i kā lākou mau pahuhopu. Ke hana nui nei mākou e hoʻokō i kēia kūlana lanakila-lanakila.
