Hoʻopili ʻia ka paipu kila maʻemaʻe e ke kila poepoe holoʻokoʻa, a ʻo ka paipu kila me ka weld ʻole ma luna o ka ʻili i kapa ʻia ʻo seamless steel pipe. E like me ke kaʻina hana, hiki ke hoʻokaʻawale ʻia ka paipu kila maʻemaʻe i loko o ka paipu kila hoʻoheheʻe wela, ʻo ka paipu kila liʻiliʻi i ke anuanu, ka paipu kila ʻole i ke anu, ka paipu kila extruded, ka paipu jacking a pēlā aku. E like me ke ʻano o ka ʻāpana, ua māhele ʻia ka paipu kila seamless i ʻelua ʻano: poepoe a me ke ʻano. ʻO 900mm ka palena kiʻekiʻe loa a ʻo ka palena iki he 4mm. E like me nā hoʻohana ʻokoʻa, aia nā paipu kila maʻemaʻe ʻole o ka paia a me nā paipu kila liʻiliʻi. Hoʻohana nui ʻia ka paipu kila maʻemaʻe no ka paipu hoʻoheheʻe ʻana i ka aila, petrochemicalpaipu pohā, paipu paila, lawe paipu akiʻekiʻe-precision structural kila paipuno nā kaʻa, kaʻa kaʻa a me nā mokulele. 

Wahi a ka hoʻohana ʻana ua māhele ʻia i ke kumu maʻamau (no ka wai, nā pipelines kinoea a me nā ʻāpana structural, nā ʻāpana mechanical) a me nā mea kūikawā (no nā boilers, geological exploration, bearings, acid resistance, etc.) ʻelua ʻano.

'Oloka'i 'ia ka paipu kila ma'amau e ke kila kalapona ma'amau, ke kila ho'oha'aha'a ha'aha'a a i 'ole ke kila kila kila, a loa'a ka mea nui loa, i ho'ohana 'ia ma ke 'ano he pipeline a i 'ole ka 'āpana hana no ka lawe 'ana i ka wai. Nui nā ʻano paipu hili ʻole no nā hana kūikawā, e like me nā paipu hoʻoheheʻe ʻia o ka paila, nā paipu mana kemika, nā paipu hili honua a me nā paipu ʻaila ʻole. ʻO ka paipu kila maʻemaʻeʻole he'āpana'āpana hollow a hoʻohana nuiʻia e like me ka pipeline no ka laweʻana i nā wai, e like me nā paipu no ka laweʻana i kaʻaila, ke kinoea maoli, ke kinoea, ka wai a me kekahi mau mea paʻa.

Kaʻina hana paipu kila ʻole:

① ʻO ke kaʻina hana nui o ka paipu kila liʻiliʻi i ʻōwili ʻia (△ Kaʻina nānā nui): 

Hoʻomākaukau a me ka nānā ʻana △→ Hoʻomaʻamaʻa → perforating → Rolling → hoʻomaʻamaʻa hou → Sizing → Hoʻomaʻamaʻa wela △→ Hoʻopololei → Hoʻopau → Nānā △ (non-destructive, physical and chemical, nānā papa) → waiho

② Ke kaʻina hana nui o ka paipu kila ʻole i ʻōwili ʻia (kau ʻia)

Hoʻomākaukau hakahaka → hoʻomaʻamaʻa ʻiʻo → ʻōwili anuanu (kahakiʻi) → Hoʻomaʻamaʻa wela → hoʻopololei → hoʻopau → nānā.

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana o ka paipu kila maʻamau i ʻelua ʻano kiʻi anu a me ka ʻōwili wela, ʻoi aku ka paʻakikī o ke kaʻina hana ma mua o ka ʻōwili wela, ʻoi aku ka paʻakikī o ka tube billet i ʻekolu ʻōwili mau, extrusion ma hope o ka hoʻāʻo ʻana, inā ʻaʻole pane ka ʻili i ka māwae ma hope o ka ʻoki ʻana i ka ʻokiʻoki e ʻoki ʻia e ka mīkini ʻokiʻoki, e ʻoki ana i ka ulu ʻana o hoʻokahi mika. A laila e hoʻokomo i ke kaʻina hana annealing, annealing me ka waiʻawaʻawa pickling, pickling pono e hoʻolohe i ka nui o nā ʻōpū ma luna o ka ʻili, inā he nui nā ʻōhū, 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 liʻiliʻi liʻiliʻi ma mua o ka paipu kila liʻiliʻi ʻole, ʻoi aku ka liʻiliʻi o ka pā o ka paipu kila liʻiliʻi i ʻōwili ʻia, akā ʻoi aku ka mālamalama o ka ʻili ma mua o ka paipu kila maʻemaʻe, ʻaʻole ʻoʻoleʻa ka ʻili, ʻaʻole ʻoi aku ka nui o ka pahu.

Hāʻawi ʻia ke kūlana hoʻopuka o ka paipu kila maʻemaʻe ʻole ma hope o ka mālama ʻana i ka wela. Hot olokaa seamless kila paipu ma hope o ka nānā 'ana i ka maikaʻi e hele i loko o ko ke kookoo koʻikoʻi manual koho, ma hope o ka quality inspection e hoʻokō i ka aila ili, a laila ukali e ka helu o ka anu hoʻokolo kiʻi hoʻokolohua, wela olokaʻa lapaʻau e hoʻokō i ka ho'āʻo o ka perforation, ina ka perforation enlargement nui loa e straightener. Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia ia i ka mīkini ʻike kīnā e ka mīkini hoʻouna no ka hoʻokolohua ʻike kīnā, a hope loa i hōʻailona ʻia, hōʻano ʻia a waiho ʻia i loko o ka hale kūʻai.

Poepoe paipu blank → hoʻomehana → perforation → ʻekolu-roll skew rolling, hoʻomau i ka ʻōwili ʻana a extrusion → Wehe ʻia → ka nui ʻana (a hōʻemi paha) → Hoʻomaʻamaʻa → hoʻopololei → hoʻāʻo ʻana i ke kaomi wai (a i ʻole ka nānā ʻana) → Marking → ʻO ka paipu kila maʻemaʻe i loko o ka waihona i hana ʻia me ka ingot kila a i ʻole ka paipu paʻa paʻa ʻole ma o ka perforation a laila ʻolokaʻi ʻia a ʻōwili ʻia paha. Hōʻike ʻia nā kikoʻī o ka paipu kila seamless e ke anawaena o waho * ka mānoanoa o ka pā o nā millimeters.

ʻO ke anawaena o waho o ka paipu hoʻoheheʻe wela i ʻoi aku ka nui ma mua o 32mm, ʻo ka mānoanoa o ka pā he 2.5-200mm, ʻo ke anawaena o waho o ka paipu kila liʻiliʻi liʻiliʻi hiki ke 6mm, hiki ke 0.25mm ka mānoanoa o ka pā, ʻo ke anawaena o waho o ka paipu lahilahi-walled hiki ke 5mm, ʻoi aku ka nui o ka mānoanoa o ka paia ma mua o 0.25mm. paipu hili ʻole wela.
