Ko te whakahou mōhiohio hou mō te paipa tapawha，Te hipoki i te ahunga whakamua hangarau、Ngā mahi mākete me ngā kōrero ahumahi：
Te ahunga whakamua hangarau
Hangarau hanga tika tiketike
Kua whakatutukihia e te kamupene whakaputa putorino tapawha kāinga te whakaputa putorino tapawha tapawha tiketike，Ka taea te whakatutuki i te tika o te rahi±0.05mmi roto。Hei tauira，Shanghai Jia maitai makariri i raro i te awhina o te North University Hangarau me Dalian Sangao Company，Kua whakawhanakehia te raina hanga hanga waewae matatini tino tika，Whakamahia te pūkaha-whakahaere rack kake tiketike、Whakauru4Hangarau me ētahi atu rārangi roller。
Ngā āhuatanga hangarau tirotiro tika tiketike，COPRA®Kei te whānui te whakamahia o te matawai screenshot papamahi，Ka taea te whakatutuki i te inenga hapa kore o ngā wāhanga kōtaha，me te whakataurite ki te wāhanga hoahoa pai，Te whakatau tere me te tika i te rerekētanga。
Hangarau hanga ngāwari
R me te whanaketanga o te mīhini hanga makariri hou hanga whakaritenga o te paipa tapawha atu ngāwari。Hei tauira，Te mīhini hanga makariri piko o te whanui hurihia hurihia e Dalian Fuji me ētahi atu kamupene，Te kaha ki te nohopuku ki te hanga o ngā hua whakaritenga rerekē。
Hanganga Mill hou（pērā i te miihini waea rere）Te whakarei ake i te ngāwari me te āheinga o te hanga putorino tapawha。
Ngā rauemi hou me ngā tukanga hou
Beijing University o te Pūtaiao me te Hangarau whakawhanakehia hangarau hou ki te hanga pokepokea pouaka tapawha nui，Kua angitu650×650mmwhai ake nei、Te matotoru taiepa mōrahi25mmhanga putorino tapawhā。
Ling Steel Steel Pipe Company R & D mahi tiketike、High-tika pourewa paipa tapawha motuhake，WhakamahiaQ355Brauemi，matotoru taiepa12mm，Te kaha mo te paipa welding noa1.94ngā wā。
