Me te tinipaipa maitai kore-tuituingā tipu i Haina, mehemea he torutoru noa iho ngā māngai ka taea e koe te whiriwhiri, ko wai te tuatahi ka puta ake ki te hinengaro?

I tēnei rā, ka matapakihia e tātou takitahi, mai i te raki ki te tonga.

Me tīmata tātou ki te Tai Rāwhiti o Haina. Ko te Ansteel Seamless Steel Pipe Plant, i whakatūria i te tau 1953, koia te tuatahi o ngā wheketere paipa maitai kore hononga i New China, e mōhiotia ana i roto i te umanga ko te "cradle".

Ko tōna kaha whakaputa he 500,000 tāne/tau, me ngā whakatakotoranga mai i te Φ60-180mm, ko te nuinga e whakaputa ana i ngā paipa puna hinu, ngā paipa paipa, me ngā ngongo kōhua.

He pakari te turanga me te hangarau pumau o Ansteel, ā, he ingoa pai tonu tōna i roto i ngā mara tukatuka hinu me te mīhini.

Muri iho, me titiro tātou ki te Tai Tokerau o Haina. Ko te Paipa Rino Tianjin, e mōhiotia ana i roto i te umanga ko "TPCO" (Great Seamless), he 3.5 miriona tana te kaha whakaputa ā-tau, neke atu i te 1.5 miriona tana o ēnei he paipa puna hinu, e whakanoho ana i a ia ki roto i te taumata teitei o te kaha whakaputa kotahi-whakanao puta noa i te ao.

Koia te kaiārahi o te motu mō ngā hua papai pērā i ngā paipa paipa moana hohonu, ngā paipa puna hinu poka hohonu rawa, me ngā paipa puna hinu ātete-waikura.

I te poto: Ko te Tianjin Steel Pipe te kōwhiringa tuatahi mō ngā kaupapa moana hohonu me ngā puna hohonu taumata-motu.

Kei te raki o Haina anō hoki te rōpū Baogang, e whakamahi ana i ngā rauemi whenua onge o Baotou hei pupuri i ngā painga ahurei o ngā paipa motuhake e ātete ana ki te waikura me te pāmahana iti.

Neke atu i te 1.2 miriona tāne te kaha whakaputa ā-tau, ā, ko ngā whakatakotoranga kei waenga i te Φ38-457mm. I te tau 2025, kua oti kē te whakaputa me te tuku i tana paipa hanganga kaha-tino teitei 690 MPa i whakawhanakehia motuhaketia.

Kua tere te ahunga whakamua a Baogang i roto i ngā paipa hanganga kounga teitei me ngā paipa hinu i ngā tau tata nei, ā, kua whiwhi hoki ia i te tiwhikete API.

I te taha rawhiti o Haina, neke atu i te 3.37 miriona tana te nui o ngā paipa maitai kore-hono a te Shandong Luli Group i te tau 2023, koia te tuatahi o te motu e pā ana ki te nui o te whakaputanga me te rahinga hoko.

Ko tana waitohu apiti, 'Panjin Steel Pipe', e ono ngā raina huri-wera matatau, ā, ko te kaha kua whakaritea kia 6 miriona tana.

Ko ngā āhuatanga o Luli ko te rahi o ngā puranga, ngā whakaritenga whānui, me te utu iti, e pai ai mō ngā kaupapa nui.

I waenganui o Haina, kua whakangaohia e Henan Fengbao Pipe Industry te 1.2 piriona yuan ki tētahi kaupapa paipa rino tino matotoru, ā, ka tata te neke atu o te kaha whakaputa paipa rino kore-honohono hurihuri-wera ki te 2 miriona tana.

Kua whakakīia e Fengbao te āputa o tōna kaha whakaputa paipa rino tuimotu nui-diameter, ā, ka eke ki te 60% o tana putanga katoa ōna kaha tukatuka hōhonu.

Ko te whāinga he hanga i tētahi turanga kounga teitei mō ngā paipa hinu, ngā paipa hanganga, me ngā ngongo poiha pēhanga teitei me te pēhanga waenga.

I Haina Waenganui anō hoki, e mōhiotia ana a Hubei Daye Special Steel, i whakatūria i te tau 1890, ko te "pūtake o te hanga maitai Hainamana hou."

Ko tōna kaha whakaputa he kotahi miriona tāne o ngā paipa maitai tuimotu kounga teitei, he pakitara matotoru-waenga, me ngā whakatakotoranga mai i te Φ51-534mm me te matotoru o te pakitara mai i te 5-130mm.

Ko rātou te rangatira o te mākete mō ngā paipa mīhini hangarau me ngā ngongo poiha pēhanga teitei. Mō ngā kaupapa he nui ngā whakaritenga hangarau, ko rātou te kōwhiringa tika.

Kua kōrerohia e mātou ētahi kamupene māngai mai i te Tai Rāwhiti, te Tai Tokerau, te Rawhiti, me te Waenganui o Haina. I te wāhanga e whai ake nei, ka haere tonu mātou ki te tonga ki te kōrero mō Baosteel me ngā tipu matua i raro i te CITIC Pacific i te Tai Rāwhiti o Haina, tae atu ki ētahi kamupene he kaha te mahi kaweake. Kia mahara ki te whai i a mātou."

Kua kōrero mātou mō ētahi kaihanga nui i ngā rohe raki me waenganui. I tēnei wā, ka neke mātou ki Haina ki te Rawhiti me te tonga. Ko tētahi kamupene e mōhiotia ana e te katoa ko Baosteel, kei Shanghai."

Haina ki te Rawhiti: Baosteel, te "Pou Tuatoru" o ngā Hua Roa Kounga Teitei

Me tīmata tātou ki a Baosteel. Kei Shanghai, he pūkaha rongonui i roto i tā tātou umanga. Ko tana mira hurihuri tonu 140-waeine te mea e whakaputa paipa maitai kore hononga nui rawa atu o te ao.

E whakamahia whānuitia ana ngā paipa taumata-pūngao i roto i ngā āhuatanga mahi uaua pēnei i te moana hohonu me te whenua hōhonu, ā, kua uru atu ana paipa puna hinu ātete-waikura 13Cr ki ngā mākete o tāwāhi.

I te tau 2025, i whakangao a Baosteel i te 4.96 piriona yuan hei hanga i tētahi turanga paipa maitai kore-hono kounga teitei, hei whakaara ake i ngā hua roa kounga teitei ki tana tuatoru o ngā hua rautaki nui rawa atu.

"Ko Baosteel te mea e mōhiotia ana e ia ko ōna pūkenga hangarau kaha, ko tōna tere ki te whakawhanake i ngā hua kounga teitei, me te haumitanga nui tonu ki te R&D i roto i te umanga."

Me kōrero tātou mō CITIC Pacific Special Steel. Ehara i te wheketere kotahi, engari he rōpū kei Jiangyin, Jiangsu tōna tari matua.

E rima āna turanga whakaputa nui: ko Xingcheng Special Steel, ko Daye Special Steel, ko Qingdao Special Steel, ko Tianjin Steel Pipe, me Jingjiang Special Steel.

I te wā o te Mahere Rima Tau 14, i whakauruhia e CITIC Special Steel ngā rauemi paipa rino o ōna turanga rerekē, ā, i whakapiki ake i tōna kaha whakaputa paipa rino tuimotu ki te 5 miriona tana, ā, koia te kaihanga paipa rino tuimotu nui rawa atu o te ao.

I te poto: koinei te haurua o ngā kaweake paipa rino o Haina.

I roto i ngā apiti o CITIC Special Steel, ko Jiangyin Xingcheng Special Steel tōna turanga matua, me te kaha whakaputa ā-tau o te 6.9 miriona tana o te maitai motuhake.

Kāore ngā hua a Xingcheng e herea noa ki ngā paipa rino, engari e whakaputa ana hoki i te rino whāriki, te rino motuka, me te rino pūngao." Ko te tūranga kaiārahi o Xingcheng i te ao katoa e whakatakoto ana i te paearu mō te umanga rino motuhake katoa.

He maha ngā putanga hangarau me ngā mahi auaha i roto i ngā paipa maitai tui kore e whakawhirinaki ana ki te tautoko rauemi e whakaratohia ana e ngā kamupene maitai motuhake matua pēnei i a Xingcheng.

I tua atu, ko Zhejiang Jiuli Special Materials he toa huna i roto i te mara o ngā paipa tui kowiri tira.

He tohunga ki ngā paipa motuhake pērā i te 304, 316L, te maitai kore waikura takirua, me ngā koranu ātete-waikura me te pāmahana teitei, me ngā whakatakotoranga mai i te Φ6-219mm me te matotoru o te pakitara mai i te 0.5-18mm, ā, he kaha whakaputa tata ki te 40,000 tana.

E whakamahia ana āna hua i roto i te mana karihi, ngā matū hinu, te pūngao hou, me te hangarau moana, me te neke atu i te 34% te tawhē hua katoa.

Ina tae ki te kowiri tira me ngā paipa koranu motuhake, he ingoa kore e taea te karo i a Jiuli.

Ki te tonga tonu, ko te Hunan Hengyang Hualing Steel Pipe, i whakatūria i te tau 1958... He umanga paipa maitai tui kore ngaio a Jianchang e whai mana nui ana i te ao.

Ko te whānui o ngā whakatakotoranga hua kei waenga i te 32-762mm, ā, ka taea hoki e ia te hanga ngongo tapawhā me ngā ngongo tapawhā.

Hei te tau 2025, ka mahi tahi rāua ko Danieli ki te hanga i te raina whakaputa huri wera tonu nui rawa atu o te ao, i hangaia me te diameter paipa mōrahi o Φ24 inihi.

Ko te kounga maitai teitei rawa atu mō ngā paipa hinu me te hau ko te HS155V, mō ngā paipa raina ka eke ki te X100Q, ā, mō ngā paipa oko pēhanga ka taea te tu atu i ngā pāmahana tae atu ki te 600℃.

I te poto: he kaiārahi nui i roto i te hanga whare teitei.

Hei whakamutunga, tirohia te tonga-mā-uru o Haina, te Panzhihua Iron & Steel Group Chengdu Steel & Vanadium. Me te kaha whakaputa ā-tau o te 2.12 miriona tana, ko ana hua e kapi ana i ngā paipa hinu, ngā ngongo poiha, me ētahi atu, ā, kei a ia te tiwhikete API me ngā raihana hanga taputapu haumaru karihi.

Ngā Whakatakotoranga: Φ6-720mm, te matotoru o te pakitara 0.5-45mm, kua whai wāhi nui ngā paipa maitai tui kore ki ngā ahumahi pēnei i te tiaki whenua, te rererangi, te mana karihi, me ngā kohua.

Ko Pangang (Pangang Group) te kaihanga paipa maitai tui kore i te tonga-mā-uru o Haina, ā, ko rātou te kaiwhakarato i ngā whakatakotoranga hua tino whānui.

Heoi anō, he maha atu anō ngā kamupene kāore i whakahuatia, pērā i a Jingjiang Special Steel, Qingdao Special Steel, Zhejiang Taifu, tae atu ki a Dalipu, Molong, Chengde, Longchuan, Jianlong, Huarun, Changjiang, me ētahi atu. Kei te tuku puku hoki rātou i ngā takoha nui ki te umanga hanga pūngao, hanganga, me te kaweake o te motu. E tino mihi ana mātou ki a rātou.

E rua tekau tau tā mātou tīma e mahi ana i te umanga paipa rino, ā, he roa te wā e mahi tahi ana mātou me ēnei mira maitai. Ahakoa te momo paipa rino e hiahiatia ana e koe, mā mātou koe e āwhina ki te kimi i te kaiwhakarato tino tika. Māu e whakarite te ota, ā, mā mātou e whakarite te taurite.
