Ngā Pūrongo - Paipa ERW vs Paipa SSAW vs Paipa LSAW

Te Mārama ki ngā Rerekētanga i waenga i ngā Paipa Rino ERW, SSAW, me LSAW

He mea nui te mahi a ngā paipa rino i roto i ngā kaupapa hanga whare, hinu me te hau, me ngā kaupapa hanganga whenua.Paipa ERW, Paipa Rino SSAW, me ngā paipa rino whakarewa LSAWko ngā momo e toru e whakamahia whānuitia ana.

Rōpū Rino o te Kuini(Kaiwhakarato Ngongo Rino), he kaiwhakarato o te ao, e tuku ana i ngā maitai ka taea te whakarite kia rite ki ngā hiahia o te kaupapa, ā, e whakarato ana hoki i ngā otinga whānui mō ngā momo paipa maitai whakarewa e toru, hei āwhina i ngā kaimahi kirimana ki te whiriwhiri i te kōwhiringa tino tika.

He aha te paipa ERW?

Paipa maitai waro ERWKa hangaia te (Paipa Hiko Ātete-Hiko) mā te hurihuri i ngā koiri maitai me te whakarewa i te hononga ki te ātete hiko auau-tiketike.

Ngā Āhuatanga Matua:
He mata maeneene, he pai te manawanui ki ngā āhuatanga
He ohanga mō te whakaputa papatipu
E tika ana mō ngā diameters iti me te diameters waenga

Ngā tono noa:
Paipa Hanganga
Ngā tūāpapa hanga
Taonga me ngā ngongo miihini
Te kawe wai i te pēhanga iti

He aha te paipa SSAW?

Paipa Rino SSAWKo te (Spiral Submerged Arc Welded Pipe) he tikanga whakarewa i hangaia kia porowhita i ngā taha o ngā koiri maitai e tika ana, ā, ka hangaia ngā koiri hei paipa mā te whakamahi i te iahiko aukume auau teitei, ā, ka whai ake ko te HFIW, ko te whakarewa koiri pewa ruku rānei (SAW).

Ngā Āhuatanga Matua:
Te kaha o te diameter nui
Te whakaputa roa ngāwari
Te utu iti o ngā rauemi mata

Ngā tono noa:
Ngā paipa wai
Te mahi pou me te turanga
Te tuku hinu me te hau (pēhanga iti ki te pēhanga waenga)

He aha te paipa LSAW?

Paipa Rino LSAW(Te Paipa Whakarewa Āwhata Roa) ka hangaia mā te whakapiko i ngā pereti maitai kia rite ki te āhua o te paipa porowhita, kātahi ka whakarewahia te hononga kia roa.

Ngā Āhuatanga Matua:
Te kaha nui, te pono nui
Mō ngā tono pakitara matotoru
Pai rawa atu mō ngā mahi pēhanga teitei

Ngā tono noa:
Ngā paipa hinu me te hau
Ngā kaupapa o waho o Romania
He paipa maitai kaha, he hanganga pakari hoki, mō te hanga whare taumaha.

Te Whakamahinga Pai rawa atu	Hanganga	Te puranga / te wai	Hinu me te hau / pēhanga teitei

Me pēhea te whiriwhiri i te paipa maitai tika?

Ko te paipa tika e whakawhirinaki ana ki tāu mahi:

Kōwhiria te Paipa ERW → mō te whakamahinga ōhanga i roto i ngā tono hanganga
Whiriwhiria te Paipa SSAW → he pai mō ngā mahi poupou whānui
Tīpakohia te Paipa LSAW → mō ngā tono hanganga pēhanga teitei me ngā tono hanganga nui

Ngā Pātai Auau

He aha te rerekētanga i waenga i ngā paipa ERW me ngā paipa SSAW?
He mea whakapiri tika ngā paipa ERW, ko ngā paipa SSAW ia he mea whakapiri porowhita, kia nui ake ai te diameter.

He kaha ake te paipa ERW, te paipa LSAW rānei?
He kaha te paipa LSAW, ā, he mea tika kia noho ki te wāhi e tika ana te pēhanga teitei.

He paipa SSAW mō te hinu me te hau?
Āe, engari ko te nuinga mō ngā paipa pēhanga iti-waenga.

Ko tēhea paipa te mea iti rawa te utu?
Ko ngā ngongo ERW te mea tino ohanga.
