Muindasitiri yemapaipi,API 5Lndiyo chiyero chinobatanidza zvese. Asi kana ukanyatsotarisa pane spec, haisi gwaro rekuti "saizi imwe chete inokodzera zvese". Kusarudza pakati peAPI 5L Giredhi BuyeAPI 5L X70, kana kusarudza kana purojekiti ichida PSL2 zvechokwadi, ndipo panotanga kuoma mainjiniya.
Nheyo Yekutanga: PSL1 vs. PSL2
Sarudzo yekutanga mune chero nzira yekutenga iChikamu Chekutsanangurwa Kwechigadzirwa.API 5L PSL1Yakanakira mashandisirwo ekutanga, API 5L PSL2 imhuka yakasiyana zvachose. Yakagadzirirwa nzvimbo dzine njodzi dzakanyanya, dzakadai semitsetse yegesi ine simba rakawanda kana mapuratifomu ekunze.
| Fkudya | PSL1 | PSL2 |
|---|---|---|
| Bvunzo yeCVN Impact inosungirwa | No | Ehe |
| Simba reKubereka Denga | Hapana | Zvinosungirwa (Zvinogumira pakusimba zvakanyanya) |
| Chiyero Chekubereka Chakanyanya | Hapana | Kazhinji 0.93 |
| Kutevedzana | Yekutanga | Kunyatsoteverwa Kunodiwa |
| Mutsetse weWeld NDT | Yekutanga | Zvinosungirwa (Radiographic kana Ultrasonic) |
Kemikari: Kufambira Mberi kwe "Kuchena"
Vanhu pavanotaura nezve "hunhu" hwePSL2, vanowanzo taura nezvemakemikari. Miganhu yePhosphorus neSulfur yakanyanya kusimba muPSL2 nekuti tsvina iyi ndiyo inokonzera kukundikana mumunda.
Heino maitiro ayo makemikari anowanzoputsika kune mamwe makirasi akafanana:
| Chikamu (Chakanyanya %) | Giredhi B rePSL1 | Giredhi B rePSL2 | PSL2 X70 |
|---|---|---|---|
| Kabhoni (C) | 0.26 | 0.22 | 0.22 |
| Manganese (Mn) | 1.20 | 1.20 | 1.65 |
| Phosphorus (P) | 0.030 | 0.025 | 0.025 |
| Sarufa (S) | 0.030 | 0.015 | 0.015 |
Chimwe chinhu chekutarisira iCEV. MuPSL2, CEV haisi kungopa zano chete; muganho wakaoma unoita kuti pombi ikwanise kusungirirwa mumunda pasina kutsemuka. Kana kabhoni iri shoma kwazvo, chigayo chinoshandura kufomura yePcm kuti chipe mufananidzo wakarurama wekuchinjika.
Kushanda Kwemakanika Uye Simba
Zita regiredhi rinokuudza simba remugoho wepasi. Pombi yeX52 ine mugoho wepasi we52,000 psi. Asi muPSL2, simba remugoho wepasi "repamusoro" rakakosha semugoho wepasi. Kana pombi yakaoma zvakanyanya kana kuti yakasimba zvakanyanya, inorasikirwa neductility inodiwa kuti ikwanise kubata kufamba kwepasi kana kumanikidzwa.
| Giredhi | Kugohorera Kushoma (MPa) | Kubudirira Kwakanyanya (MPa) | Min Tensile (MPa) | Kusimba Kwakanyanya (MPa) |
|---|---|---|---|---|
| Giredhi B | 245 | 450 | 415 | 760 |
| X52 | 360 | 530 | 460 | 760 |
| X60 | 415 | 565 | 520 | 760 |
| X70 | 485 | 635 | 570 | 760 |
Kuedzwa kweDzvinyiriro: Fomura yeHydrostatic
Chikamu chimwe nechimwe chepombi yeAPI 5L chinofanira kupasa bvunzo yemvura. Ndihwo humbowo hwekupedzisira hwekuti chigayo chakaita basa racho. Kumanikidzwa kunoshandiswa hakusi nhamba isina kurongeka; kunoverengwa zvichibva pahunhu hwepombi uchishandisa fomura inotevera:
Muequation iyi,Pkumanikidzwa kwekuyedza,tukobvu hwemadziro, uyeDndiyo dhayamita yekunze. Iyo variableSinomiririra kushushikana kwefiber, iyo inowanzo kuve pakati pe60% ne90% yesimba repaipi rakatarwa. Kune PSL2, bvunzo inowanzo chengetwa kwenguva yakareba kuti ive nechokwadi chekuti weld seam yakanyatsogadzirwa.
Basa reSour
Kana pombi yako iine gasi "rinovava" (H2S), magiredhi akajairwa haadi kuabvisa. Unofanira kutsvaga ma suffix ekuti “MS” kana “NS”, akadai seX52MS. Mapaipi aya anoongororwa HIC. Kemikari pano yakanyanya kuipa, nemazinga eSulfur anowanzo deredzwa kusvika 0.003% kudzivirira gasi kuti risadye simbi kubva mukati kuenda kunze.
Zano Rinoshanda reKuongorora
Paunenge uchiyera pombi, yeuka kuti API 5L inobvumira kushivirirana pahukobvu hwemadziro. Zvisinei, paPSL2, kushivirirana ikoko kwakasimba zvikuru. Shandisa gauge yehukuru hwe ultrasonic yakagadzikwa uye iva nechokwadi chekuti hausi kuyera zvakanaka pamucheto wekucheka apo saha ringave rakasiya burr. Kuwana kuverenga kwakarurama kubva kumagumo epombi ndiyo chete nzira yekusimbisa kuti uri kuwana simbi yawakabhadhara.
