13Cr Alloy Steel Seamless Casing Pipe L80 and P110 For Offshore Oil Drilling


13Cr casing pipe description:

13Cr alloy steel oil casing pipe 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, This kind

of pipe not only has a higher strength and excellent corrosion resistant properties, but also has

good low temperature toughness.

L80-13Cr; C95-SP13Cr1; C95-SP13Cr2; P110-SP13Cr1; P110-SP13Cr2

Features:

1. CO2 resistant oil pipe
2. Seawater corrosion resistant oil pipe
