Oil tubes 13Cr /9Cr

13Cr and 9Cr tubes are used for resisting CO2corrosion, which almost have no H2S in tubes. If using in the condition that only has CO2and Cl﹣, the strength grade equivalents to L80 steel grade of API, the tensile strength is 700MPa, the hardness is HRC22-24. We can also produce C90 and C95 steel grade Grade:We can supply high grade stainless steel tubes, such as 9Cr, 13Cr, Sup13Cr, 22Cr, 25Cr, 825, G3 etc., which above L80 grade. The producing specifications of L80 13Cr and L80 9Cr under API 5CT standard are as following Size range: Oil tube: Ф48.3—114.3; W.T: 5—20mm; Length: R2 Casing tube: Ф114.3—244.5mm; W.T.: 5—30mm; Length: R2 Casing nipple: Ф76—219.1; W.T: 6—40mm; Length: 1.5—8m. In addition, we can supply products in agreement form, according to clients’ demand. Application:Oilfield、natural gas pipe line Standard: API 5CT, API 5LD, API Q1 product certification.
