Ngā Pūrongo - ASTM A106 vs API 5L: Ko tēhea Paerewa Paipa Rino mō tō Kaupapa?

Mō ngā kaiwhakahaere kaupapa o te ao, ngā kaiwhakahaere hoko, me ngā kaiārahi hangarau, ko te whiriwhiri i te whakatakotoranga paipa tika he whakatau pai, he whakatau rānei e pā ana ki te haumaru, te tahua, me te roa o te mahi. Ina whakamahi paipa hinu, hau, wai pēhanga teitei rānei, e rua ngā waehere e puta ake ana: ASTM A106 me API 5L.

Ahakoa e tika ana ēnei e rua mō ngā paipa maitai waro, ā, he rite tonu ngā āhuatanga matū me ngā āhuatanga ā-ringa, mā te whakapoauau i a rāua ka nui te utu mō te kore e tutuki i ngā whakaritenga, ka tere rānei te pakaru o ngā paipa.

Anei tētahi whakamārama hangarau kia mōhio ai koe ko tēhea te mea e tika ana mō tō momo kaupapa.

Whānuitanga me te Whakamahinga Matua

Ko te rerekētanga matua i waenga i ēnei paerewa e rua ko te mea kua tuhia mō ngā taiao whakahaere rerekē:

Paipa Rino ASTM A106He mea hanga mō te mahi maeneene mō te pāmahana teitei me te pēhanga teitei. He mea whakamahi nui i roto i ngā paipa hinu, i ngā tipu hiko, i ngā tipu hinu matū me ngā tono poihau ina he pāmahana teitei te wai.

Paipa Rino API 5LHe paerewa tēnei i whakawhanakehia e te American Petroleum Institute mō te whakamahinga o ngā paipa i roto i ngā pūnaha kawe paipa raina i roto i ngā ahumahi hinu me te hau māori. Kua hangaia hei kawe i te hau, te wai, me te hinu mō ngā tawhiti roa me ngā wā roa i runga whenua me te moana.

Ngā Tikanga Hanga: Tuitui kore, tuitui whakarewa rānei

Ko te ngāwari o te hanga he rerekētanga matua anō hoki mō te whakamahere hoko:

Ko te hanga paipa maitai waro maeneene (Ngā Tohu A, B, me te C) anake te kōwhiringa e wātea ana mō te ASTM A106.

Kei roto i te API 5L ngā whirihoranga paipa tuturu me ngā whirihoranga whakarewa mō ngā whakaritenga paipa whānui. Ko ngā momo whakarewa ko te paipa API 5L ERW (Electric Resistance Welded), te paipa maitai LSAW (Longitudinal Submerged Arc Welded), te paipa maitai SSAW (Spiral Submerged Arc Welded).

Ngā Tohu Rauemi me te Hanganga Matū

He mea nui te mārama ki te pūnaha whakatauranga mō ngā tataunga hanganga me ngā whakatauranga pēhanga:

Paerewa	Ngā Tohu Noa	Kaha Kume (Minimum)	Kaha Hua (Minimum)
ASTM A106	Taumata A, ASTM A106 Taumata B, Taumata C	415 MPa (Taumata B)	240 MPa (Taumata B)
API 5L	API 5L Kōeke B, API 5L X42, API 5L X52, API 5L X60, API 5L X65, API 5L X70	415 MPa (Taumata B) ki te 570 MPa (X70)	245 MPa (Taumata B) ki te 485 MPa (X70)

Ngā Rerekētanga i roto i te Hangarau Whakarewa:

Ahakoa he tino ōrite ngā hanganga matū me ngā rohenga ā-pūkaha o te ASTM A106 Grade B me te API 5L Grade B, ka whakauruhia e te API 5L he maitai hurihuri-ā-mīhini kaha ake (ngā māka "X", pērā i te paipa raina API 5L X65). Mā ēnei māka teitei ake ka taea te hanga pakitara angiangi i roto i ngā paipa tawhiti, ka whakaitihia te taumaha katoa o te maitai me ngā utu utanga mō ngā kaupapa hanganga nui.

Ngā Taumata Whakatakotoranga Hua: PSL1 vs. PSL2

Ko tētahi hapa nui e mahia ana e ngā kaihoko o te ao ko te wareware i ngā taumata whakatakotoranga hua API 5L (PSL1 me PSL2):

PSL1e whakarato ana i te taumata kounga paerewa e ōrite ana ki te ASTM A106.

PSL2e whakatakoto ana i ngā whakaritenga tino kaha, ā-ture mō ngā paipa maitai waro. E whakahau ana kia whakamātauhia te pānga (whakamātautau Charpy V-notch) hei aromatawai i te pakari o te pakaru, e whakawhāiti ana i te ōrite o te waro kia pai ai te whakarewa, ā, e hiahiatia ana he whakamātautau kore-whakangaro pakari (NDE). Kāore he ōrite tika o te ASTM A106 ki ngā whakaritenga o te PSL2.

He Aratohu Whakarāpopototanga mō ngā Kaiwhakahaere Kaupapa

Kōwhiria te ASTM A106 (Sch 40 / Sch 80):Mena kei roto i tō kaupapa he paipa matatini o te whare whakapai hinu ā-rohe, he paipa mamaoa, he whakatakotoranga rānei o ngā waeine tukatuka e whakahaerehia ana i raro i te ahotea pāmahana teitei.

Kōwhiria te API 5L (X42 ki te X70):Mena kei te hanga koe i ngā paipa hinu ā-ao, i ngā paipa kohikohi me te kawe hinu ki tai, i ngā paipa rānei e hiahia ana koe ki ngā paipa nui te whānuiNgā paipa maitai API 5L kua whakarewainahe kaha ki te tu atu i te ahotea hua nui me ngā taiao hau waikawa.

Ehara i te mea he mea noa iho ngā whakaritenga te whiriwhiri i waenga i te ASTM A106 me te API 5L; engari he mea nui kia whakaitihia te mōrearea, kia whakaaetia e ngā ture, kia arotauhia hoki te utu.
