Corrosion Behavior of API 5L X80 Steel in the Produced High-strength low-alloy steel is used in pipelines, which transport oil/gas and also produced water in the process of the secondary recovery of oil. This paper investigates the corrosion of X80 steel after immersion in static systems (biotic and abiotic). The corrosion rate, the corrosion morphology and the hardness of the coupons were

Corrosion Behavior of X80 Pipeline Steel under Coupling

In this work, X80 pipeline steel produced in China was used. The soil solution simulated a alkaline soil in Daqing City. OCP, potential of stray current-induced corrosion, polarization curve of X80 steel under tensile stress (hereinafter called T S) were measured, the influence law of stress on Corrosion effect of Bacillus cereus on X80 pipeline steel The corrosion of X80 pipeline steel in the presence of Bacillus cereus (B. cereus) was studied through electrochemical and surface analyses and live/dead staining. Scanning electron microscopy and live/dead straining results showed that a number of B. cereus adhered to the X80 steel. Electrochemical

Effect of AC on corrosion behavior of X80 pipeline steel

Corrosion behavior of X80 pipeline steel under the application of various waveforms AC was investigated in concentrated carbonate/bicarbonate solution by electrochemical measurements, immersion tests, and slow strain rate tensile tests. Under the application of AC current of various waveforms, the corrosion potential shifts negatively and the Effect of Inclusion on Pitting Corrosion of X80 Pipeline SteelThe influence of inclusion on pitting corrosion of X80 pipeline steel was investigated by using electrochemical test and atomic force microscope. The results indicated that corrosion potential of X80 pipeline steel sample with higher grade inclusion was lower, and decreased significantly with chloride ion concentration increasing. Inclusion was not conducive to corrosion resistance of X80

Effects of Alloy Content on Impact Toughness in X80

The X80 pipeline steel for the west to east gas transmission project was successful produced, based on the hot strip mills equipment advantage. However, the impact toughness was unstable during the production. In this research, optical microscope, scanning electron microscopy (SEM) and energy dispersive analysis (EDS) test were used to study the relationships Experimental Research on Fatigue Properties of X80 Jan 27, 2021 · Abstract. In recent years, many synthetic natural gas demonstration projects have been put into operation all over the world, and hydrogen is usually contained in synthetic natural gas. X80 is the most commonly used high-grade pipeline steel in the construction of natural gas pipelines. The compatibility between high-grade pipeline steel and hydrogen directly affects safety and reliability of long-distance pipelines.

Fracture Toughness and Application of X80 Pipeline Steel

The fracture toughness of X80 pipeline steel, which has been widely used in China, plays a key role in pipeline safety insurance. In order to know the accurate fracture toughness of X80, the methods of acoustic emission and high K ratio have been carried out to judge the initiation of crack propagation and improve flatness of fatigue pre-crack front. High Grade Steel Pipeline for Long Distance Projects at reached the conclusion that the use of X80 was a proven technology, even with all of the risks attributable to the use of the higher strength steel. However, the reason why X80 had so far not been employed worldwide for more pipelines was not due to any valid technical reasons, nor was it due to the absence of sufficient economic incentive.

Mechanical Properties of Intercritically Annealed X80 Line

Feb 17, 2021 · The current state of the art uses X70 or X80 line pipe steel grades (yield stress of 483 and 550 MPa, respectively) with a range of different steel chemistries which have a good combination of strength, toughness, and cost-effectiveness. New Development of High Grade X80 to X120 Pipeline Steels API X80 pipeline steel is widely used in natural gas and oil transportation.
