——Nō nā tata nei, i oti pai i tā mātou kamupene te whakarato āwhina ohorere mō tētahi puranga oASTM A53 GR.Bpaipa rino kore-hono mō ngā kiritaki o Amerika ki te Tonga. Ko ngā whakatakotoranga ko SCH 40, ko te whānuitanga o waho he 189mm-273mm, ko te roa pumau he 12 mita, ā, ko te tapeke he 17 tana. Mai i te whiwhinga o te tono ki te whakaū i te wāhi, i oti te tuku i roto i ngā rā e 3 noa iho, e whakaatu ana i te kaha whakauru mekameka tuku whai hua me te whiwhi whakamoemiti nui mai i ngā kiritaki.
Ngā wero me ngā otinga mō ngā puranga iti o ngā ota kounga teitei
E rua ngā raruraru nui i pā ki te kiritaki o Amerika ki te Tonga i roto i te tukanga hokohoko: ko te tuatahi, me tutuki i ngā paipa maitai tuimotu e hiahiatia ana ngā whakaritenga tino tika.ASTM A53/A53 GR.Bngā paerewa; ko tētahi atu, ko te nui o te hoko o te 17 tana kāore i tutuki i ngā whakaritenga rahinga iti rawa o te ota o te wheketere maitai. Hei whakautu i tēnei āhuatanga, i tere te whakatūnga o tā mātou kamupene i tētahi whatunga kaiwhakarato, i taurite tika i ngā rauemi ā-wāhi, ā, i whakarato i tētahi otinga kotahi ki ngā kiritaki mai i te whakaū i ngā whakatakotoranga ki te tuku ratonga, me te whakarite i te kounga o ngā rauemi me te pono o te waitohu.
"Mō ngā ota he mārama ngā whakaritenga waitohu me te kounga, engari kāore te rahinga e tutuki i te paepae tuku tika mai i ngā mira maitai, ko tō mātou uara kei roto i te whakaurunga tere o ngā rauemi," te kī a tā mātou kaiwhakahaere pakihi. "He whānuitia te whakamahinga o ngā paipa maitai kore hononga paerewa A53 GR.B i roto i ngā mara hinu, hau me te hanga, engari he maha ngā wā ka pāngia ngā hoko iti e te roa o te wā tuku me te iti o ngā hongere."
He aha i whiriwhiri aiASTM A53 GR.Bngā paipa rino tuitui?
Te pono o ngā rauemi: He kaha ake te kaha kume o te maitai waro GR.B (≥415MPa) ā, he pai mō ngā pūnaha paipa pēhanga reo me te pēhanga teitei.
Ngā paerewa tukanga: Ka tutuki te matotoru o te pakitara SCH 40 i te nuinga o ngā āhuatanga pehanga, ā, ka whakaitihia e te roa pumau 12-mita ngā pona whakarewa i te papaanga.
Tukunga tere: Ko te whānuitanga o te diameter o waho 189mm-273mm e kapi ana i ngā whakaritenga diameter paipa noa, ā, ko te rarangi taonga i te wā kotahi e whakamana ana i te ahunga whakamua o ngā kaupapa ohorere.
Mā tēnei mahi tahi ka whakamanahia anō ngā pūkenga ngaio o tā mātou kamupene i roto i te ao o te tuku maitai motuhake iti-papanga. I ngā rā kei te heke mai, ka haere tonu tā mātou whakapai ake i te pūnaha mekameka tuku paipa maitai kore hononga, ā, ka whakarato ki ngā kiritaki o te ao i ngā otinga paipa maha-paerewa tae atu kiAPI 5LmeASTM A106.
Mō mātou:
Ko te arotahi a SanonPipe ki ngā otinga hoko rauemi ahumahi o te ao. Ko tana pakihi matua e kapi ana ingā paipa kōhua, ngā paipa hinu, ngā paipa maitai hangangame te motuhakengā koranuMā te pūnaha whakahaere rawa mamati me te mahi tahi me ngā kaiwhakarato rautaki, ka taea te whakatutuki i te urupare ota ohorere 72-hāora.
