- API 5CT K55 Casing Tubing waxaa lagu bixiyaa dhererka bilaashka ah ee u dhexeeya 8m ilaa 13m iyadoo lagu salaynayo heerka SY/T6194-96. Si kastaba ha ahaatee, sidoo kale waa la heli karaa wax aan ka yarayn dhererka 6m iyo tirada waa in aanay ka badnayn 20%.
- Qalloocyada aan kor ku soo sheegnay lama oggola inay ka soo baxaan dusha sare ee API 5CT K55 Casing Tubing coupling.
- Qallooc kasta sida timaha timaha, kala soocida, xuubka, dildilaaca ama qoloftu maaha mid la aqbali karo gudaha iyo dibadda dusha alaabta. Dhammaan cilladahan waa in gebi ahaanba meesha laga saaraa oo qoto dheer ee la saaray waa in aanay ka badnayn 12.5% dhumucda derbiga magacaaban.
- Dusha sare ee dunta isku xidhka iyo API 5CT K55 Casing Tubing waa in ay ahaataa mid siman iyada oo aan lahayn wax jeexan, jeexan ama cillado kale oo saameyn xun ku yeelan kara xoogga iyo isku xirnaanta dhow.
Waxaa muhiim u ah hawl-wadeennada saliidda iyo gaaska inay ka ilaaliyaan wax-soo-saarkooda si fiican u daxalka ilaalinta cathodic & API 5CT OilField Tubing ayaa ugu horreyn u adeegta gudbinta saliidda iyo gaaska.
