corrosion resistant high cr steel for oil and gas wells


Related with this, stainless steels like 13% Cr and 22% Cr present a good corrosion resistance; nevertheless, their cost is very high compared with carbon steel tubulars. Keeping in mind the necessity of oil industry to reduce production costs, tubing manufacturers developed less chromium alloys to cover less severe CO2 partial pressure applications.

AMPP Store - 08085 High Performance Corrosion Resistant

In a 1998 study, costs for corrosion in USA were estimated to be about 276 billion [email protected] One way to reduce this gigantic amount of money [email protected] use modern stainless steels and nickel alloys with excellent resistance to various forms of [email protected] corrosive environments like seawater, brines, oil and sour gas wells. Corrosion Behavior of 3% Cr Casing Steel in CO2-Containing The main corrosion products of 3% Cr steel were found to be FeCO 3, Cr 5 O 12, Fe 2 O 3, and Fe-Cr, in which Cr 5 O 12 can contribute to corrosion resistance of 3% Cr steel by forming the thin and tight film. CO 2 caused a drastic change in the polarization behavior of 3% Cr steel. The anodic Tafel slope became larger in the sweet brine, indicating stronger dissolution of 3% Cr steel.

Corrosion Performances Of Modified 13Cr For Octg In Oil

Mar 09, 1997 · The application field of API-13% Cr martensitic stainless steel (AISI 420, hereafter referred to as 13Cr) is steadily increasing due to its good C0 2 corrosion resistance and cost effectiveness [1, 2]. From 1980 to 1993, more than 2400 km of 13Cr OCTG were reported to be installed in oil and gas wells [3]. Corrosion performances of modified 13Cr for OCTG in oil Aug 01, 1997 · Martensitic and duplex steels are increasingly used in the oil and gas industries when high CO {sub 2} environments are encountered. Nevertheless, very often the field conditions make traditional 13% Cr steel insufficient due to its limited corrosion resistance and the duplex being too expensive. This paper is aimed at evaluating the performances of new 95 ksi grade and new 110 ksi

The utility of iron alloys depends on minimizing the corrosion rate. Corrosion of steel is an electrochemical process, involving the transfer of electrons from iron atoms in the metal to hydrogen ions or oxygen in water. The corrosion reaction of iron with acid is described by the equation ..(1) This reaction is made up of two individual processes, which Corrosion Resistance of Martensitic Stainless Steels in Dec 01, 1998 · Martensitic stainless steels (SS) have been used widely for oil-country tubular goods (OCTG) because of their high strength and excellent corrosion resistance in carbon dioxide (CO 2) gas wells.Cr-rich precipitates form after tempering heat treatments of martensitic SS. Environment-Assisted Cracking of Corrosion-Resistant ABSTRACT What are Corrosion-Resistant Alloys? Corrosion-resistant alloys (CRA) refer primarily to Fe-Cr stainless steels (SS) and Ni-Cr-Mo alloys that are normally passive in corrosive environments. Alloy compositions, which range from Type 410 (UNS S41000)(1) martensitic stainless steel (MSS) to Alloy C-276 (UNS N10276), a Cr-Ni-Mo alloy, have been used in the production of oil and gas for
