Pombi yeClad yeBimetal Metallurgical yeX65+316L | Pombi yeCRA Inodhura Mari Yebasa reCO₂ - Womic Steel

Tsananguro pfupi:

Pombi Yekunze (Simbi Inotsigira):API 5L X65 PSL2 - simba rakakwirira, kusimba kwakanyanya, inonamirwa

Kufukidza kwemukati (CRA Cladding):316L (UNS S31603) – simbi isina ngura ine kabhoni shoma, inodzivirira ngura yeCO₂, uye inogona kusvetwa zvakanaka

Saizi Yehukuru:OD 219mm – 1219mm (8″ – 48″); Ukobvu hwemadziro esimbi inotsigirwa 8mm – 30mm; Ukobvu hwechifukidziro 1.5mm – 3.0mm; Kureba kumwe chete kusvika 18m (24m yakagadzirwa inowanikwa)

Maitiro Ekugadzira:Kusungana kwemupumburu unopisa + JCOE kugadzira – simba rekuchekerera chisungo chesimbi ≥200 MPa

Mitemo & Zvitupa:API SPEC 5LD (CRA Clad Steel Pipe), DNV-OS-F101, NACE MR0175, ISO 15156. Chitupa cheMill EN 10204 Rudzi 3.1. Kuongororwa kwevamwe (SGS, BV, DNV, TÜV) kuripo.

Mashandisirwo:Mapaipi ekuunganidza gasi rechisikigo ari kumahombekombe, mitsetse yekuisa CO₂, masisitimu ekupinza mvura, mitsetse yemafuta negasi ine chloride shoma, mapaipi anobatanidza fekitari yekuchenesesa.

Simbi yeWomicinopa pombi dzakasungirirwa nesimbi dzeX65+316L - imwe nzira inodhura zvishoma pane alloys dzakasimba dze316L kana kupfuura. Yakagadzirirwa sevhisi inotapira (CO₂ isina H₂S kana chloride dzakakosha). Inotsigirwa nemagwaro emhando yepamusoro uye ruzivo rwekutumira pasi rose.

1. Pfupiso - Nei X65+316L Clad Pipe

Pamapaipi anotakura gasi rechisikigo rine carbon dioxide (CO₂) asi pane huwandu hushoma hwehydrogen sulfide (H₂S) uye machloride mashoma, simbi yakasimba yekabhoni inokurumidza kuora, nepo simbi yakasimba ye316L isingatsvedzeri inowanzo shandiswa zvakanyanya uye inodhura zvakanyanya.

X65+316L bimetallic yakasungwa nesimbi yakaputirwa nesimbiinopa nzvimbo yepakati yakakodzera:

Rutivi rwekunze rweX65inopa simba guru (inobereka zvishoma 450 MPa), kusimba kwekutyoka, uye kudzora kumanikidzwa - izvo chaizvo zvinozivikanwa neAPI 5L X65 line pipe.

Kufukidza kwemukati kwe316Linosangana zvakananga nemvura, ichidzivisa ngura yeCO₂, oxidation yakajairika, uye mamiriro eacidic akapfava.

Matinji maviri aya anobatanidzwa zvachose nechisungo chesimbi (hot roll bonding + JCOE forming). Hapana njodzi yekuti liner iputsike, ikwinyate, kana kupatsanurwa - kusiyana nepombi dzakagadzirwa nemakanika.

Musanganiswa uyu unoshandiswa zvakanyanya mumasisitimu ekuunganidza gasi rechisikigo rinotapira,Mapaipi eCO₂ ekuwedzera mafuta ekudzoreredza (EOR),mitsetse yekuisa mvurauyenzira dzemafuta negesi dzine chloride shoma.

4. Maitiro Ekugadzira - Hot Roll Bonding + JCOE

Womic Steel inogadzira pombi dzakaputirwa dzeX65+316L dzichishandisa nzira dzakabudirira dzeindasitiri.chisungo chinodziya chemupumburu + JCOE chinoumbanzira:

Kugadzirira pamusoro– Maplate eX65 ne316L anocheneswa, kukuyiwa, uye kuongororwa.

Kuungana kwevacuum stack– Maplate maviri aya akarongedzwa nechikamu che316L chakatarisa mukati, chakavharwa pasi pevacuum kuti oxygen ibviswe.

Kupisa kutenderedza– Murwi wacho unopiswa kusvika 1150-1250°C uye unopfuudzwa nemuchina unotenderera. Kuderedzwa kwakanyanya (5:1 kusvika 10:1) kunoita kuti pave nechisungo chesimbi kuburikidza nekupararira kweatomu.

Kutonhodza nekutarisa ndiro– Ndiro yakaputirwa yakatonhodzwa, uye chisungo chacho chakaongororwa zvizere kuti chionekwe kana chaparara.

Kuumbwa kweJCOE– Ndiro yakaputirwa inogayiwa pamucheto, yozogadzirwa kuita pombi yakavhurika uchishandisa michina yakatevedzana yeJCO.

Kusonwa kwemusono werefu– Musono wakavhurika unosungirirwa uchishandisa welding yesimbi inonyungudika padivi kaviri (SAW) ine 316L kana 309L yekuzadza pa inner pass uye carbon steel yekuzadza pa outer pass.

Kuwedzera (sarudzo)- Kuwedzera kwemuchina kunovandudza kutenderera uye kunoderedza kushushikana.

Kurapa kupisa– Kurapa kupisa mushure mekuweld (PWHT) kunoshandiswa kana zvichidikanwa nezvinodiwa neprojekiti.

NDT uye kuyedzwa– Ona Chikamu 5 pazasi.

Kupedzisa kupedzisa– Migumo yakachekwa ine mafuta anodzivirira ngura uye zvivharo zvepurasitiki.
