13Cr L80 tubing or casing is used for the chlorides H2S or Carbon dioxide Corrosion oil well,gas well or water well,with the superior premium thread maintain the higher tight seal capacity.
Martensitic stainless steel is a type of stainless steel that can adjust its mechanical properties through heat treatment. Simply put, it is a type of hardenable stainless steel.Typical grades are 1Cr13,2Cr13,3Cr13,
4Cr13, etc.After quenching,the hardness is higher,and different tempering temperatures have different combinations of strength and toughness,such as Grade 420 MOD,L80-13Cr,S13Cr 95ksi,S13Cr 110ksi,13Cr-110Ksi.
Martensitic stainless steel 13Cr L80 Tubular goods suitable environment as follows:
Petroleum products contain a large amount of carbon dioxide, dissolved salts, and hydrogen sulfide,which can easily react with internal pipelines during transportation. Especially in the later stage of oilfield development, due to water injection and extraction, the water content of the transportation medium increases,thereby exacerbating the corrosion inside the pipelines.
Carbon dioxide corrosion is influenced by many factors,mainly including carbon dioxide partial pressure, temperature,pH value,medium flow rate, carbonate scale,and the effect of wax.The significant impact on carbon dioxide corrosion is the thermal movement of carbon dioxide in the aqueous phase.
The hydrogen sulfide often contained in oil and gas itself does not cause corrosion to pipelines,but when it encounters water in the conveying medium, it will ionize,leading to electrochemical corrosion reactions in pipelines.
