Ngā Pūrongo - Te Mārama ki te Rerekētanga i waenga i ngā Paipa Rino ERW, SSAW, me DSAW

He mea nui te mahi a ngā paipa rino i roto i ngā hanganga o te ao o ēnei rā, mai i ngā paipa hinu me te hau ki te tuku wai me ngā tono hanganga. I roto i ēnei, ko ngā mea tino rongonui ko ngāPaipa whakarewa ERW, Paipa maitai SSAW, Paipa maitai DSAWMā te mōhio ki ngā rerekētanga i waenga i ēnei hua ka taea e ngā kaihangarau, ngā kaimahi kirimana me ngā kaihoko te whiriwhiri i te paipa pai rawa atu mō ā rātou mahi.

Paipa Rino ASTM A671 CC65 CL 12 EFW mō ngā Mahi Ahumahi me ngā Hanganga (1)

He aha te paipa maitai ERW?

Paipa maitai ERWe pā ana ki tētahi paipa rino e hangaia ana mā te whakamahi i te whakarewa ātete hiko. Ko te hua o tēnei ko te hanganga o tētahi hononga roa i te roanga o te paipa.

Ko ētahi o ngā āhuatanga matua o ngā paipa ERW e whai ake nei:
DiameterIti ki te waenga (10 mm – 508 mm te nuinga).
Matotoru o te PakitaraAngiangi ki te waenga (te matotoru noa ≤20 mm).
Ngā tonoMō ngā paipa wai, ngā paipa hau, me ngā wāhanga hanganga me ngā wāhanga miihini.
Ngā PaingaHe tino tika ngā āhuatanga, he maeneene te mata o roto, he ohanga hoki.
Te HerengaKāore e tika ana mō te ratonga pēhanga tino teitei.

He aha te paipa maitai SSAW?

SSAW (Whakapiripiri Porowhita Rukuhia)paipa maitai, e kiia ana hoki ko te HSAW, ka hangaia mā te hurihuri i tētahi rīpene maitai kia āhua porowhita, ka whakarewahia te hononga mā te whakamahi i te whakarewa pewa i raro i te wai.

Ngā āhuatanga matua o ngā paipa SSAW:
Diameter: Waenganui ki te tino rahi (400 mm–3600 mm+).
Matotoru o te PakitaraAngiangi ki te waenga (≤25 mm noa).
TuituiHe hononga porowhita i te koki ki te tuaka o te paipa.
Ngā tonoNgā paipa hinu me te hau, te kawe wai, ngā kaupapa hanganga nunui.
Ngā Painga: Ka taea te whakaputa i ngā diameter nui me te matotoru pakitara ngāwari.
Ngā HereKa whakaitihia te kaha o te pēhanga e te hononga porowhita ki te whakataurite ki ngā paipa DSAW roa.

He aha te paipa maitai DSAW?

Paipa maitai DSAW (Whakapirihia te Pewa Ruku Takirua)he rite tonu kiPaipa LSAW (Rongonui Rukuhia te Āwhata)He mea hanga tēnei mā te whakapiko i te pereti maitai mai i te 1/2 inihi ki te 3 inihi te matotoru ki roto i tētahi rango, ā, ka whakarewaina ngā hononga o roto, o waho hoki mā te whakamahi i tētahi tukanga whakarewa pewa i raro i te wai.

Ngā āhuatanga matua o te paipa DSAW:
Diameter: Waenga ki te rahi (300–2500 mm te paerewa).
Te matotoru o te pakitaraMatotoru waenga ki te matotoru (≥6 mm ki te 50 mm+).
WhakamahiaNgā paipa hinu me te hau pēhanga teitei me ngā paipa tai, ngā tono hanganga e hiahia ana kia kaha te kaha.
Ngā PaingaHe pakari, he pono hoki ngā tuitui, ā, he mea tino pai te rauemi mō ngā āhuatanga taumaha.
Ngā ngoikoretangaHe nui te utu o te whakaputa, ā, he puhoi ake te tukanga whakaputa ki te whakataurite ki te ERW me te SSAW.

Ngā Ratonga a te Rōpū Rīra Rōia o Haina

Rōpū maitai kingi o Hainahe kaihanga ngaio o ngā hua paipa rino me ngā paipa rino ERW (Electric Resistance Welded), SSAW (Spiral Submerged Arc Welded) me DSAW (Double Submerged Arc Welded) me ētahi atu. I runga i ngā tau o te wheako ahumahi, ka tukuna e te kamupene he kōrero hangarau katoa me ngā tohutohu mō te momo paipa tino tika hei whakamahi i roto ite tuku hinu me te hau, te tuku wai, ngā mahi ahumahi pēhanga teitei, me ngā kaupapa toto totoka, me ētahi atu tono.

Ka whakaarohia e te Royal Steel Group ngā āhuatanga maha pēnei i tete rahi o te paipa, te matotoru o te pakitara, te taumata rauemi, te akomanga pēhanga, te ātete ki te waikura, me ngā āhuatanga taiaohei tautuhi i ngā otinga tino pai. Hei tāpiri, ka whakaratohia e te China Royal Steel Group he ratonga hanga me te ratonga paninga kua whakaritea (arā, te ārai-waikura, te whakapūmau, te arai epoxy) me te whakapumautanga kounga pakari me ngā paerewa o te ao o ASTM, ISO me te API.

Mā te hangarau matatau, te whakamātautau tika me te tautoko whakahaere, ka taea e te kamupene te whakarato i ngā hua paipa rino e tutuki ana i ngā paerewa haumaru, pakari me te mahi pakari, e āhei ai ngā kiritaki ki te whakarato i ngā otinga hanganga utu tika, pumau, me te whai hua.

Ko te whiriwhiri i te paipa maitai tika e whakawhirinaki ana ki ngā whakaritenga o te kaupapa, te whānui, te matotoru o te pakitara, me te whakatauranga pēhanga:

Ngā paipa ERWHe iti te utu, he pai mō ngā diameter iti ki te rahi waenga me ngā tono pēhanga iti ki te rahi waenga.

Ngā paipa SSAWHe pai mō ngā paipa whānui me te matotoru o te pakitara.

Ngā paipa DSAWKo te kōwhiringa pai rawa atu mō ngā tono pēhanga teitei, kaha teitei pērā i ngā paipa moana, hinu me te hau rānei.

Mā te mārama ki ngā rerekētanga i waenga i ngā paipa maitai ERW, SSAW, me DSAW ka tino pai te mahi, te haumaru, me te whai hua o te utu mō tētahi kaupapa hanganga.
