Tubing has many different types,which types of the tubing has its own unique features and usage.Today I will introduce one kind of the tubing which with good performance in CO2 corrosion resistant.
CO2 corrosion resistant premium connection tubing and casing, with good performance in CO2 corrosion resistant, which is specially designed by seal lock connection applies to sour oil & gas well that contains CO2 or both CO2 and CL¯. Pipe body is produced with economic low-alloy steel billet containing Cr, Ni, Mo etc or stainless 13Cr, 15Cr steel billet, which have good performance in thermodynamic stability. Alloy component can directly block anode process and promote cathodic process. The activity of element can help the formation of corrosion resistant structure containing high, stable alloy component on the surface , whose thickness is about several atomic layers .It also helps improve CO2 corrosion resistant ability. KPE’s tubing and casing with special patent gas-sealing connection joint, , applies to different complex and serious well condition.
The standards of the tubing are shown as below:
API Spec 5CT
NACE-TM0171 Autoclave Corrosion Testing of Metals in High-Temperature Water
API Spec 5B
ISO 13679/GB/T 21267
