Mu makampani opanga mapaipi,API 5Lndiye muyezo womwe umasunga zonse pamodzi. Koma ngati muyang'ana mosamala zomwe zili mu chikalatachi, si chikalata cha "kukula kumodzi komwe kumagwirizana ndi zonse". Kusankha pakati paAPI 5L Giredi BndiAPI 5L X70, kapena kusankha ngati pulojekiti ikufunikadi PSL2, ndi pamene uinjiniya umakhala wovuta.
Chiyambi: PSL1 vs. PSL2
Chisankho choyamba mu njira iliyonse yogulira ndi Mulingo Wofotokozera Zamalonda.API 5L PSL1Ndi yabwino pa ntchito zoyambira, API 5L PSL2 ndi yosiyana kwambiri. Yapangidwira malo omwe zinthu zimakhala zovuta kwambiri, monga mizere ya gasi yothamanga kwambiri kapena nsanja zakunja kwa nyanja.
| Fchakudya | PSL1 | PSL2 |
|---|---|---|
| Mayeso Oyenera a CVN Impact Test | No | Inde |
| Denga Lolimba la Zokolola | Palibe | Zofunikira (Zimaletsa mphamvu zopitirira muyeso) |
| Chiŵerengero Chokwera Kwambiri | Palibe | Kawirikawiri 0.93 |
| Kutsata | Zoyambira | Kutsata Konse Kumafunika |
| Mzere Wothira NDT | Zoyambira | Zofunikira (Zojambula pa X-ray kapena Ultrasonic) |
Chemistry: Kupita Patsogolo pa "Chiyero"
Anthu akamalankhula za "ubwino" wa PSL2, nthawi zambiri amalankhula za kapangidwe kake. Malire a Phosphorus ndi Sulfur ndi ochepa kwambiri mu PSL2 chifukwa zonyansa izi ndi zomwe zimapangitsa kuti zinthu zilephereke m'munda.
Apa ndi momwe chemistry imagwera nthawi zambiri pamagulu angapo ofanana:
| Chinthu (Choposa %) | PSL1 Giredi B | PSL2 Giredi B | PSL2 X70 |
|---|---|---|---|
| Kaboni (C) | 0.26 | 0.22 | 0.22 |
| Manganese (Mn) | 1.20 | 1.20 | 1.65 |
| Phosphorus (P) | 0.030 | 0.025 | 0.025 |
| Sulfure (S) | 0.030 | 0.015 | 0.015 |
Chinthu chimodzi choyenera kusamala nacho ndi CEV. Mu PSL2, CEV si lingaliro chabe; ndi malire olimba omwe amatsimikizira kuti chitolirocho chikhoza kulumikizidwa m'munda popanda kusweka. Ngati mpweya uli wochepa kwambiri, mpheroyo idzasinthira ku fomula ya Pcm kuti ipereke chithunzi cholondola cha kusunthika.
Magwiridwe antchito ndi mphamvu za makina
Dzina la giredi limakuuzani mphamvu yocheperako yopezera mphamvu. Chitoliro cha X52 chili ndi mphamvu yocheperako ya 52,000 psi. Koma mu PSL2, mphamvu yopezera mphamvu "yokwanira" ndi yofunika mofanana ndi mphamvu yocheperako. Ngati chitoliro chili cholimba kwambiri kapena champhamvu kwambiri, chimataya mphamvu yogwirira ntchito yofunikira poyendetsa kayendedwe ka nthaka kapena kukwera kwa mphamvu.
| Giredi | Kuchuluka Kwapang'ono (MPa) | Kuchuluka Kwambiri (MPa) | Kulimba Kwapang'ono (MPa) | Kulimba Kwambiri (MPa) |
|---|---|---|---|---|
| Giredi B | 245 | 450 | 415 | 760 |
| X52 | 360 | 530 | 460 | 760 |
| X60 | 415 | 565 | 520 | 760 |
| X70 | 485 | 635 | 570 | 760 |
Kuyesa Kupanikizika: Fomula Yothira Madzi
Cholumikizira chilichonse cha chitoliro cha API 5L chiyenera kupambana mayeso a hydro-test. Ndi umboni womaliza wakuti mpheroyo yachita ntchito yake. Kupanikizika komwe kwagwiritsidwa ntchito si nambala yosasinthika; imawerengedwa kutengera mawonekedwe enieni a chitolirocho pogwiritsa ntchito njira iyi:
Mu equation iyi,Pndi kupanikizika koyesa,tndi makulidwe a khoma, ndipoDndi dayamita yakunja. ChosinthikaSikuyimira kupsinjika kwa ulusi, komwe nthawi zambiri kumakhala pakati pa 60% ndi 90% ya mphamvu yocheperako yopezera mphamvu ya chitoliro. Pa PSL2, mayeso nthawi zambiri amasungidwa nthawi yayitali kuti atsimikizire kuti msoko wothira weld uli bwino.
Utumiki Wowawasa
Ngati payipi yanu ili ndi mpweya "wowawasa" (H2S), magiredi wamba sadzachepetsa. Muyenera kuyang'ana ma suffix a "MS" kapena "NS", monga X52MS. Mapaipi awa amayesedwa ndi mayeso a HIC. Mankhwala apa ndi ochulukirapo, ndipo nthawi zambiri Sulfur imatsitsidwa mpaka 0.003% kuti mpweya usadye chitsulocho kuchokera mkati kupita kunja.
Malangizo Othandiza Oyendera
Mukamayesa chitoliro, kumbukirani kuti API 5L imalola kulekerera pang'ono makulidwe a khoma. Komabe, pa PSL2, kulekerera kumeneko kumakhala kolimba kwambiri. Gwiritsani ntchito choyezera makulidwe a ultrasonic choyezera ndipo onetsetsani kuti simukuyezera bwino m'mphepete mwa chodulira pomwe choduliracho chingakhale chitasiya burr. Kupeza kuwerengera kolondola kuchokera kumapeto kwa chitoliro ndiyo njira yokhayo yotsimikizira kuti mukupeza chitsulo chomwe mudalipira.
