Tianjin Yuantai Derun Rōpū JCOE Φ1420 nuipaipa kanite wāhanga i whakatinanahia hei whakakī i te āputa i te mākete o Tianjin
Ko te JCOE he hangarau hanga paipa mō te whakaputa i ngā paipa maitai matotoru te whānui, e hangai ana ki te tukanga whakaputa whakarewa pewa rua-taha e rukuhia ana, ka mirahia te hua, ka pikohia i mua, ka pikohia, ka tuituihia, ka whakarewahia ki roto, ka whakarewahia ki waho, ka whakatikatikahia, ka papatahi hoki i roto i ngā tukanga maha. Ka taea te wehewehe i te tukanga hanga ki ngā taahiraa N+1 (he tauoti pai a N), ka whāngaihia aunoatia te pereti maitai me te piko whakarara i roto i ngā taahiraa kua whakaritea hei whakatutuki i te hanganga JCO ahunga whakamua CNC. Ka tomo te pereti maitai ki te mīhini hanga i te ahunga whakarara, ā, ka peia e te taraka whāngai hei mahi i te taahiraa tuatahi o ngā taahiraa N/2 o te piko maha-taahiraa hei whakatutuki i te hanganga "J" o te haurua tuatahi o te pereti maitai; ko te taahiraa tuarua ka tere te whāngai whakarara o te pereti maitai kua hangaia "J" ki te tūranga whakarara kua tohua, mai i tetahi atu pito o te pereti maitai kāore anō kia hangaia mō tētahi atu taahiraa N/2 o te piko maha-taahiraa, hei whakatutuki i te haurua tuarua o te hanganga pereti maitai, hei whakaoti i te hanganga "C"; Hei whakamutunga, ko te wāhanga o raro o te paipa "C" ka piko kotahi kia tutuki ai te "Ko ia taahiraa o te pēhi e hangai ana ki te kaupapa taketake o te piko-toru-ira."
Paipa maitai LSAWhe tūranga nui i roto i ngā mahi nuipaipa raina lsawngā kaupapa, ngā kaupapa tuku wai me te hau, te hanganga whatunga paipa tāone, te whakatū pou piriti, te hanganga ā-tāone me te hanganga tāone. I ngā tau tata nei, hei momo pūnaha whare penapena hiko hou me te hoahoa taiao, kua whakanuia te whare hanganga maitai hei "whare matomato" o te rautau 21. I roto i te kaupapa hoahoa whare teitei me te tino teitei ki te tuku i te kaupapa matua ki te whakamahi i te pūnaha hanganga maitai, maitai-raima rānei, ngā whare whānui-whānui e whakamahi kaha ana i te hanganga whatunga mokowā, te hanganga anga-toru-ahu, te hanganga kiriuhi taura me te pūnaha hanganga kua mua i te taumahatanga, koinei ngā paipa maitai i roto i te hanganga o ngā horopaki tono maha atu, ā, kua piki ake hoki te tono mō ngā paipa maitai nui-whānui, pakitara-matotoru-rahi. Inaa, ko tengā paipa kani me ngā paipa kanii hangaia e Yuantai Derun Steel Pipe Manufacturing Group e whakamahia whānuitia ana. Hei kounga teiteikaihanga paipa lsawi Haina, kei te whai wāhi a Yuantai Derun ki te tuku paipa maitai mō ngā kaupapa nui maha.
Nō nā tata nei, kua paahitia e Tianjin Yuantai Derun Steel Pipe Manufacturing Group te tiwhikete e pā ana kiPaipa kani API 5L, ā, ka whānui ake te whakamahinga i roto i ngā momo mara ā muri ake nei. Ko ngā hua matua kopaipa maitai waro lsaw, paipa maitai lsaw diameter nui, mepaipa maitai whakarewa lsaw.
Ka taea e te wāhanga JCOEΦ1420 o Tianjin Yuantai Derun Steel Pipe Manufacturing Group te whakaputa i ngā whakatakotoranga mai i te Φ355.6mm ki te Φ1420mm te whānui me te matotoru o te pakitara tae atu ki te 50mm, ka whakakī i te āputa i roto i te mākete Tianjin mō ēnei hua ina whakamahia, ā, ka taea te whakapoto i te wā arahi mō te tono i ngā paipa porowhita hanganga matotoru rawa, he nui rawa te pakitara. Ka taea te whakamahi tika i te paipa whakarewa pewa rua-taha i raro i te wai, he paipa whakarewa roa nui mō te tuku hinu me te hau, kua whakamahia whānuitia te paipa maitai JCOE i roto i te kaupapa tuku hau ā-motu "Te Hauāuru-Rawhiti", i te mea ka taea te whakamahi hei paipa maitai hanganga ki te hanganga o te hanganga maitai tino teitei, hei tāpiri atu ki te whakamahinga o te tukanga "porowhita ki te tapawhā" ka taea te tukatuka kia nui rawa te diameter. Hei tāpiri, ka taea te tukatuka i te tukanga "porowhita ki te tapawhā" hei paipa maitai tapawhā matotoru rawa, he nui rawa te pakitara, ka taea te whakamahi i roto i ngā whare whakangahau nui me te hanga mīhini me ngā taputapu taumaha.
