1. Dulmar Guud - Sababta Tuubada X65+316L Loogu Xiray
Dhuumaha qaada gaaska dabiiciga ah ee ka kooban kaarboon laba ogsaydh (CO₂) laakiin kaliya xaddi raad ah oo ah haydarojiin sulfide (H₂S) iyo koloriin yar, birta kaarboon adag si dhakhso ah ayay u mirqaantaa, halka birta adag ee aan lahayn 316L ay badanaa aad u cayiman tahay oo qaali tahay.
Tuubo bir ah oo isku xidhan oo X65 + 316L ahwaxay bixisaa meel dhexe oo ku habboon:
Lakabka X65 ee dibadda ahwaxay bixisaa xoog sare (ugu yaraan wax soo saar 450 MPa), adkaanta jabka, iyo xakamaynta cadaadiska - sida saxda ah ee tuubada xariiqda API 5L X65 loo yaqaan.
Dahaarka gudaha ee 316Lsi toos ah ayuu ula xiriiraa dareeraha, isagoo iska caabinaya daxalka CO₂, oksaydheynta guud, iyo xaaladaha aashitada khafiifka ah.
Labada lakab waxaa si joogto ah isugu xira isku xidh bir ah (isku xidhka kulul ee duuban + sameynta JCOE). Ma jirto khatar ah in dahaarka uu dumo, laalaabmo, ama kala go'o - si ka duwan tuubo farsamo ahaan loo dahaadhay.
Isku-darkaan waxaa si weyn loogu isticmaalaa gudahanidaamyada ururinta gaaska dabiiciga ah ee macaan,Dhuumaha soo kabashada saliidda ee la xoojiyay ee CO₂ (EOR),Khadadka duritaanka biyaha, iyoqulqulka saliidda iyo gaaska ee koloriin yar.
