Mena kei te hiahia koe ki te mōhio atu ki ētahi atu kōrero, pēnei i te whakatau utu, ngā hua, ngā otinga, me ētahi atu, prīhiwhakapā mai ki a mātou i runga ipurangi.
He toa hokohoko a Tianjin Sanon Steel Pipe Co., Ltd. Kei te Tāone o Cangzhou, Porowini o Hebei tō mātou wheketere. Ko ā mātou puna matua o ngā taonga kongā paipa kōhua, ā, ko ngā rauemi e whakaatu ana i tēnei koASTM A335 P5/P11/P91/P92,ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. Ko ngā rauemi matua mō ngā paipa paipa koAPI 5L,API 5CT, ngā rauemi matua mō ngā paipa pakaru hinuGB/T 9948he 15MoG/12CrMoVGKo te GB/T 6479-2013 e tohu ana i ngā rauemi 10#/20#, ngā ngongo whakawhiti wera SA179/SA210/SA192, me ētahi atu. Ko ngā ngongo miihini GB/T 8162 e tohu ana i ngā rauemi 10#/20#/Q345/42CrMo, ko te EN10210 e tohu ana i ngā rauemi S355JOH/S355J2H, ko ngā ngongo rango hau GB1 8248 e tohu ana i ngā rauemi 34CrMo4/30CrMo.
Te hoko me te whakatau tata i ngā paipa maitai waro
He hua auau-rahi te paipa maitai waro e tirohia ana, e hokona ana hoki e ngā kiritaki. Ko ngā whakatakotoranga noa ko:ASTM A106 GRB, te whānui o waho 60-273mm, te matotoru o te pakitara SCH40-SCH80. I mua i te hoko, me āta tirotiro ngā taipitopito o ngā hiahia o te kiritaki, me te pātai atu ki ngā kaiwhakarato mō ngā utu. Ko ngā kaiwhakarato kounga teitei e mahi tahi ana mātou ko Baosteel, Hengyang, TPCO, Anhui Tianda, Luli, Fengbao, me ētahi atu, ā, ka arotahi mātou ki ngā taonga o te wā tonu kia tere ai te whakautu ki ngā hiahia o te kiritaki.
Mena ka whakaratohia e te kaiwhakarato he utu mō te ngongo tahanga, me tukatuka anō, tae atu ki te utu uta, ngā utu tukatuka me ngā utu tirotiro (e ai ki ngā hiahia o te kiritaki). Ko ngā whakamātautau taketake ko te diameter o waho, te matotoru o te pakitara, te ine roa, me te whakaū whakaahua, ataata rānei. Ka taea te whakarite tirotiro a te hunga tuatoru me te mahi tahi, ā, ka purangahia ngā whakaahua paipa rino katoa hei tohutoro.
Te hoko me ngā āhuatanga o ngā paipa maitai koranu
He rite te tukanga hoko o ngā paipa maitai koranu ki ērā o ngā paipa maitai waro, engari he rerekē rawa te mahi a ngā rauemi. Ko te rino me te waro te nuinga o te mea he mea hanga ki te maitai waro, he iti te utu, ā, he pai mō te hanga papatipu, engari kāore i te pakari, ā, he ngāwari ki te pakaru i ngā pāmahana iti. Ka tāpirihia e te maitai koranu ngā huānga pēnei i te chromium, te nickel, me te molybdenum hei whakapai ake i te ātete ki te waikura, te kaha o te pāmahana teitei, me te ātete ki te kakahu. Hei tauira:
ASTM A335 P5, P9, P11, P22,P91
Ngongo rango hauGB/T 18248-2021 34CrMo4, 37Mn
E 20,000 tāne o ngā ngongo koranu kei roto i te taonga i te tau katoa hei whakatutuki i ngā hiahia kanorau.
Ngā mea matua mō te hokongā paipa hinumengā paipa
Ko ngā paipa hinu me ngā paipa wai e whakamahia ana mō ngā ota hangarau, mō te whakakī anō rānei. Ko ngā tāne iti te mea e pai ake ana mō te hoko ā-wā, ā, ko ngā ota nui me arotake me te whakarite wā. Ko ngā ota hangarau e tohu ana i ngā waitohu me ngā whakaritenga tono. Ka taea e mātou te whakarato tuhinga tohu hei tautoko i te tono. Ko ngā keehi angitu e kapi ana i Īnia, Nepal, Vietnam, Bahrain, Peru, Nigeria me ētahi atu whenua, me te wheako pakari ki ngā mahi tono hangarau.
Whakarāpopototanga
Me tutuki tika ngā hiahia o ngā kaihoko i roto i te hoko paipa rino maeneene. He āhuatanga motuhake tō ia paipa rino waro, paipa koranu, paipa hinu me paipa raina. Ka whakawhirinaki mātou ki ngā kaiwhakarato kounga teitei me te nui o ngā taonga hei whakarite i te tuku tika, me te tautoko hoki i ngā ratonga tukatuka me te tirotiro ritenga hei whakarato i ngā otinga paipa rino pono mō ngā kaupapa o te ao.
