Chikwama ndi Machubu a API 5CT L80-9Cr
Kufotokozera Kwachidule:
Chikwama ndi mapaipi okhazikika a API 5CT L80-9Cr okhala ndi kukana dzimbiri kwambiri pazitsime za mpweya wowawasa. Abwino kwambiri m'malo okhala ndi CO₂ ndi H₂S.
Chikwama ndi Machubu a L80-9Cr:
Chikwama ndi machubu a L80-9Cr ndi zinthu zapamwamba kwambiri za OCTG zopangidwa motsatira malangizo a API 5CT. Zili ndi 9% ya chromium, chinthuchi chimapereka kukana kwabwino kwambiri ku CO₂ ndi H₂S corrosion, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito mu zitsime zamafuta ndi gasi. Ndi mphamvu yabwino kwambiri yamakina komanso kutentha kozimitsidwa komanso kofewa, L80-9Cr imatsimikizira kugwira ntchito kwanthawi yayitali m'malo otentha kwambiri komanso opanikizika. Imapezeka m'mitundu yonse ya kukula, mitundu ya ulusi, ndi kutalika (R1–R3), mapaipi athu a L80-9Cr amakwaniritsa zosowa zofunika kwambiri zamapulojekiti a m'mphepete mwa nyanja ndi zitsime zakuya.
