Karakteristik tib API 5CT K55
- API 5CT K55 Aman Tubing yo ofri ak yon seri longè gratis soti nan 8m a 13m sou baz nòmal SY/T6194-96. Sepandan, li disponib tou pa mwens pase 6m longè ak kantite li yo ta dwe pa plis pase 20%.
- Deformation ki mansyone pi wo a yo pa gen dwa parèt sou sifas ekstèn nan API 5CT K55 Casing Tubing kouple.
- Nenpòt deformation tankou liy cheve, separasyon, pli, krak oswa scab pa akseptab sou tou de sifas enteryè ak deyò nan pwodwi a. Tout domaj sa yo ta dwe konplètman retire ak pwofondè a retire pa dwe depase 12.5% nan epesè miray nominal.
- Sifas la nan fil nan kouple ak API 5CT K55 Aman Tubing yo ta dwe lis san okenn burr, chire oswa lòt domaj ki ka gen yon enpak negatif sou fòs la ak koneksyon fèmen.
Li enpòtan pou operatè lwil oliv ak gaz yo pwoteje kav pi pwodiksyon yo kont korozyon ak pwoteksyon katodik ak API 5CT OilField Tubing prensipalman sèvi pou transfere lwil oliv ak gaz.
