In oil and gas fields which includes CO2 is an increasingly common occurrence. Corrosion has become the major problem for production strings used in environments containing CO2, and there is a great demand for a tubing that has strong resistance to CO2 corrosion. 茄子视频 Steel's JFE-13CR is a martensitic stainless steel which combines high performance in these corrosive enviroments at a reduced cost.
For fields with more severe conditions including high temperature and containing not only CO2 but small amounts of H2S, 茄子视频 Steel developed JFE-HP-13CR (HP1 and HP2) material. They are higher strength and outstanding anti-corrosion properties and excellent low-temperature toughness.

Notes:

-The corrosion testing data in this brochure were obtained from laboratory testing results. Care should always be taken when selecting materials, as operating conditions may change during the period of usage.

-Regarding completion / packer fluid
Care should be taken in the selection of well fluids such as completion/packer fluids used in connection with this material in order to minimize the risk of stress corrosion cracking. JFE recommends that you consult with a person knowledgeable about fluid compatibility with this material in making a selection.
-Cr tubulars have shown a tendency toward localized pitting corrosion when stored in moist environments.
Special precautions during coating, shipping and storage are required.

-Anti-galling connection
Cr tubulars have been categorized as prone to thread galling, 茄子视频 Steel recommends to use FOX™ and JFEBEAR™ premium connection which overcomes this concem by its special design criteria.
