Corrosion Behaviour of Bitumen Coated API 5l X65 Steel

gas production is corrosion of carbon steel which causes major economic loss [2]. As a result of corrosion, crack of the pipe wall often causes collapse of petroleum and gas pipelines. The collapse is followed by huge losses of the products, environmental pollution and ecological disasters [3]. Effects of chloride ions on corrosion of ductile Environmental Api Carbon Steel Pipe CorrosionChloride is reported to play a significant role in corrosion reactions, products and kinetics of ferrous metals. To enhance the understanding of the effects of soil environments, especially the saline soils with high levels of chloride, on the corrosion of ductile iron and carbon steel, a 3-month corrosion test was carried out by exposing ferrous metals to soils of six chloride concentrations. Is the API 5L standard applicable to cast pipe?Is the API 5L standard applicable to cast pipe?This standard is not applicable to cast pipe. In a word, API 5L pipe is the carbon steel pipe applied to the oil and gas transmission system. Meanwhile other fluids like steam, water, slurry also could adopt the API 5L standard for the transmission purposes. API 5L specification covers the manufacturing types in welded and seamless.API 5L Pipe Specification (Updated on 2020) - Octal Steel
