API 5CT C90 CASING
We make API 5CT C90 Casing Tubing according to the SY/T6194-96 standard, it is open as short string sort and long string sort gave their couplings.
P11 Seamless Ferritic Alloy-Steel Pipe are reheated and furnished in the full-annealed, isothermal annealed, or normal-ized and tempered condition. If furnished in the normalized and tempered condition,the minimum tempering temperature for Grades P11are 1200°F [650°C].
