I roto i te umanga paipa,API 5Lko te paerewa e pupuri ana i ngā mea katoa kia kotahi. Engari ki te tirohia pai ngā whakaritenga, ehara i te tuhinga "kotahi te rahi e pai ana mō te katoa". Te whiriwhiri i waenga i teAPI 5L Tau Bme tētahiAPI 5L X70, te whakatau rānei mēnā me whai PSL2 tētahi kaupapa, koinei te wāhi e uaua ai te mahi hangarau.
Te Tūāpapa: PSL1 vs. PSL2
Ko te whakatau tuatahi i roto i tētahi tukanga hokohoko ko te Taumata Whakatakotoranga Hua. AhakoaAPI 5L PSL1He pai te API 5L PSL2 mō ngā tono taketake, he tino rerekē te API 5L PSL2. He mea hanga mō ngā taiao he nui ake ngā tūponotanga, pērā i ngā raina hau pēhanga teitei, ngā papaaho tai rānei.
| Fāhua | PSL1 | PSL2 |
|---|---|---|
| Whakamātautau Pānga CVN Whakahau | No | Āe |
| Te tuanui kaha hua | Kāore | Me Whakahau (Ka whakawhāiti i te kaha rawa) |
| Ōwehenga Hua Mōrahi | Kāore | Ko te tikanga 0.93 |
| Te Whai Aroturuki | Taketake | Me Whai Aroturuki Katoa |
| Raina Whakarewa NDT | Taketake | Me Whakahau (Irahiko, Ultrasonic rānei) |
Te Matū: Te Neke Atu i te "Parakore"
Ina kōrero te tangata mō te "kounga" o te PSL2, ko te matū te tikanga e kōrerohia ana e rātou. He tino kuiti ake ngā rohe mō te Phosphorus me te Whanariki i roto i te PSL2 nā te mea ko ēnei poke te take o ngā rahunga i te mara.
Anei te wehewehenga o te matū mō ētahi tohu noa:
| Huānga (Mōrahi %) | PSL1 Tau B | PSL2 Tau B | PSL2 X70 |
|---|---|---|---|
| Waro (C) | 0.26 | 0.22 | 0.22 |
| Manganēhi (Mn) | 1.20 | 1.20 | 1.65 |
| Whēkau (P) | 0.030 | 0.025 | 0.025 |
| Whānariki (S) | 0.030 | 0.015 | 0.015 |
Ko tētahi mea hei tirotiro māu ko te CEV. I roto i te PSL2, ehara te CEV i te whakaaro noa iho; he rohe mārō e whakarite ana ka taea te whakarewa i te paipa i te parae me te kore e pakaru. Mena he iti rawa te waro, ka huri te mira ki te tātai Pcm hei homai i tētahi pikitia tika ake o te kaha whakarewa.
Te Mahi me te Kaha o te Mīhini
Mā te ingoa o te karaehe ka kitea te kaha tuku iti rawa. Ko te kaha tuku iti rawa o te paipa X52 he 52,000 psi. Engari i roto i te PSL2, he rite tonu te hiranga o te kaha tuku "mōrahi" ki te kaha tuku iti rawa. Mena he mārō rawa, he kaha rawa rānei te paipa, ka ngaro te ngāwari e hiahiatia ana hei whakahaere i te nekehanga whenua, i ngā ngaru pēhanga rānei.
| Tau | Hua iti rawa (MPa) | Huanga Mōrahi (MPa) | Te Kukū Iti rawa (MPa) | Te Kukū Mōrahi (MPa) |
|---|---|---|---|---|
| Taumata B | 245 | 450 | 415 | 760 |
| X52 | 360 | 530 | 460 | 760 |
| X60 | 415 | 565 | 520 | 760 |
| X70 | 485 | 635 | 570 | 760 |
Whakamātautau Pēhanga: Te Tātai Waipūmau
Me whakaoti e ia hononga o te paipa API 5L te whakamātautau wai. Koinei te tohu tino pai i mahi te mira i tana mahi. Ehara te pēhanga i whakamahia i te tau matapōkere; ka tatauhia i runga i ngā āhuatanga ā-tinana o te paipa mā te whakamahi i te tātai e whai ake nei:
I roto i tēnei whārite,Pko te pēhanga whakamātautau,tko te matotoru o te pakitara, ā,Dko te diameter o waho. Ko te taurangiSe tohu ana i te ahotea muka, arā, kei waenganui i te 60% me te 90% o te kaha tuku iti rawa kua tohua o te paipa. Mō te PSL2, he maha ngā wā ka roa ake te whakamātautau kia mōhio ai kei te tino pai te hononga whakarewa.
Ratonga Kawa
Mena kei te kawe tō paipa i te hau "kawa" (H2(S), kāore e ranea ngā momo paerewa. Me rapu koe i ngā kupu tāpiri "MS" "NS" rānei, pērā i te X52MS. Ka whakamātauhia ēnei paipa ki te HIC. He tino kaha ake te matū i konei, ā, ka pēhia ngā taumata o te whanariki ki raro ki te 0.003% hei ārai i te hau kei kai i te maitai mai roto ki waho.
Tohutohu Tirotiro Whaihua
I a koe e ine ana i te paipa, kia maumahara ka taea e te API 5L te tuku i tētahi ātete ki te matotoru o te pakitara. Heoi, mō te PSL2, he tino kuiti ake aua ātete. Whakamahia he ine matotoru ultrasonic kua whakatikatikaina, ā, kia tino mohio kei te ine tika koe i te taha tapahi i te wāhi i waiho ai pea he kōhao i te kani. Ko te tiki i tētahi pānui tika mai i te pito rawa o te paipa te huarahi anake hei whakaū kei te whiwhi koe i te maitai i utua e koe.
