Chitoliro cha X65+316L cha Bimetal Metallurgical Clad | Chitoliro Chotsika Mtengo cha CRA cha Ntchito ya CO₂ - Womic Steel

Kufotokozera Kwachidule:

Chitoliro Chakunja (Chitsulo Chothandizira):API 5L X65 PSL2 - mphamvu yayikulu, kulimba kwambiri, komanso kusunthika

Chivundikiro chamkati (CRA Cladding):316L (UNS S31603) - chitsulo chosapanga dzimbiri chopanda kaboni wochepa, cholimba ku CO₂ dzimbiri, komanso cholimba bwino

Kukula kwa Kukula:OD 219mm – 1219mm (8″ – 48″); Chitsulo chothandizira khoma makulidwe 8mm – 30mm; Chivundikiro cha khoma makulidwe 1.5mm – 3.0mm; Kutalika kumodzi mpaka 18m (24m yovomerezeka ikupezeka)

Njira Yopangira:Kulumikizana kwa Hot roll + JCOE kupanga - mphamvu yochepetsera mawonekedwe a bond yachitsulo ≥200 MPa

Miyezo ndi Ziphaso:API SPEC 5LD (CRA Clad Steel Pipe), DNV-OS-F101, NACE MR0175, ISO 15156. Chiphaso cha Mill EN 10204 Mtundu 3.1. Kuyang'anira kwa chipani chachitatu (SGS, BV, DNV, TÜV) kulipo.

Mapulogalamu:Mapaipi osonkhanitsira gasi lachilengedwe m'mphepete mwa nyanja, mizere yojambulira CO₂, makina ojambulira madzi, mizere yotsika ya mafuta ndi gasi, malo oyeretsera mafuta olumikizira mapaipi.

Chitsulo cha Womicimapereka chitoliro chophimbidwa ndi zitsulo cha X65+316L - njira yotsika mtengo m'malo mwa aloyi olimba a 316L kapena apamwamba. Yopangidwira ntchito yokoma (CO₂ yopanda H₂S kapena ma chloride ambiri). Yothandizidwa ndi zolemba zapamwamba komanso luso lotumiza padziko lonse lapansi.

1. Chidule - Chifukwa Chake Chitoliro Chokhala ndi X65 + 316L

Pa mapaipi onyamula mpweya wachilengedwe wokhala ndi carbon dioxide (CO₂) koma pali zochepa chabe za hydrogen sulfide (H₂S) ndi ma chloride ochepa, chitsulo cholimba cha carbon chimawonongeka mwachangu, pomwe chitsulo chosapanga dzimbiri cha 316L nthawi zambiri chimakhala chokwera mtengo kwambiri komanso chokwera mtengo.

Chitoliro chophimbidwa ndi zitsulo cha X65 + 316L cha bimetallicimapereka malo abwino pakati:

Gawo lakunja la X65imapereka mphamvu zambiri (kutulutsa kochepa 450 MPa), kulimba kwa kusweka, komanso kusunga mphamvu - chomwe chitoliro cha mzere wa API 5L X65 chimadziwika nacho.

Chivundikiro chamkati cha 316Limakhudza mwachindunji madzi, kukana dzimbiri la CO₂, kukhuthala kwachilengedwe, komanso acidity yochepa.

Zigawo ziwirizi zimalumikizidwa kosatha ndi mgwirizano wachitsulo (hot roll bonding + JCOE forming). Palibe chiopsezo cha kugwa kwa liner, makwinya, kapena kulekanitsidwa - mosiyana ndi chitoliro chopangidwa ndi makina.

Kuphatikiza kumeneku kumagwiritsidwa ntchito kwambiri mumakina osonkhanitsira mpweya wachilengedwe wokoma,Mapaipi obwezeretsa mafuta owonjezereka a CO₂ (EOR),mizere yojambulira madzindimafuta ndi mpweya wochepa wa chloride.

4. Njira Yopangira - Hot Roll Bonding + JCOE

Womic Steel imapanga chitoliro cha X65+316L pogwiritsa ntchito chitoliro chodziwika bwino cha makampani.hot roll bonding + JCOE kupanganjira:

Kukonzekera pamwamba– Ma mbale a X65 ndi 316L amatsukidwa, kuphwanyidwa, ndi kuunikidwa.

Kusonkhana kwa vacuum stack– Ma mbale awiriwa ali ndi gawo la 316L loyang'ana mkati, lotsekedwa pansi pa vacuum kuti mpweya uchotsedwe.

Kugubuduzika kotentha– Chokocho chimatenthedwa kufika pa 1150-1250°C ndipo chimadutsa mu mphero yozungulira. Kuchepetsa kwambiri (5:1 mpaka 10:1) kumapanga mgwirizano wa zitsulo mwa kufalikira kwa atomiki.

Kuziziritsa ndi kuyang'ana mbale– Mbale yophimbidwayo yazizira, ndipo chigwirizanocho chayesedwa ndi 100% kuti chisawonongeke.

Kupanga JCOE– Mbale yophimbidwa imaphwanyidwa m'mphepete, kenako imapangidwa kukhala chitoliro chotseguka pogwiritsa ntchito makina osindikizira a JCO angapo.

Kuwotcherera kwa msoko wautali– Msoko wotseguka umalumikizidwa pogwiritsa ntchito cholumikizira cha arc chomwe chili m'mbali ziwiri (SAW) chokhala ndi chodzaza cha 316L kapena 309L pa cholumikizira chamkati ndi chodzaza cha carbon steel pa cholumikizira chakunja.

Kukulitsa (ngati mukufuna)- Kukulitsa kwa makina kumathandizira kuti chizungulire chikhale chozungulira komanso kuchepetsa kupsinjika komwe kumachitika.

Chithandizo cha kutentha- Chithandizo cha kutentha pambuyo pa weld (PWHT) chimagwiritsidwa ntchito ngati pakufunika malinga ndi zomwe zafotokozedwa mu polojekitiyi.

NDT ndi mayeso– Onani Gawo 5 pansipa.

Malizitsani kumaliza- Malekezero opindika okhala ndi mafuta oletsa dzimbiri ndi zipewa zapulasitiki.
