API 5CT Super 13cr Casing Pipe for Oilfield Production

• Customization: Available

Product Description

 It can be applied to oil and gas well production that contain carbon dioxide and chlorine ion acidic medium, meanwhile, in order to adapt to the high temperature and the bad environment of carbon dioxide and a small amount of hydrogen sulfide coexist, we developed a series of super 13Cr pipe , the product not only has a higher strength and excellent corrosion resistant properties, but also has good low temperature toughness.
