    Carbon steel pipe mainly refers to the carbon mass fraction is less than 2.11% without containing deliberately added alloying elements of steel, with the level of carbon contained in a steel being one of the most important factors to be influence on its the strength of the steel, the hardness increases, and reduces ductility, toughness and weld ability. Besides, it generally also contain a small amount of silicon, manganese, sulfur, phosphorus in addition to carbon. Compared to other types of steel, it is the earliest, low cost, wide range of performance, the largest amount. Suitable for nominal pressure PN 32.0MPa, temperature -30-425 water, steam, air, hydrogen, ammonia, nitrogen and petroleum products, and other media. Carbon steel pipe is the earliest to use the largest amount of basic material in modern industry. The world’s industrial countries, in efforts to increase high strength low alloy steel and alloy steel production, which is also very attention to improving the quality and expanding the range of varieties and use. Proportion of the production in the countries’ total output of steel, approximately maintained at about 80%, it is not only widely used in buildings, bridges, railways, vehicles, ships and all kinds of machinery manufacturing industry, but also in the modern petrochemical industry, marine development, has also been heavily used.

    Carbon steel pipe is used for conveying oil , gas and other fluids. Standard: API SPEC 5L,ISO 3183,ASTM A 53M,ASTM A 106M,JIS G 3454,JIS G 3455, JIS G 3456

    Surface treatment of steel pipe:

    In order to improve the service life of oil pipeline, surface treatment is usually carried out to facilitate the firm combination of steel pipe and anti-corrosive coating.Common processing methods are: cleaning, tool derusting, pickling, shot blasting derusting four categories.

    1 :cleaning Grease, dust, lubricant, organic matter adhered on the surface of steel pipe, usually using solvent, emulsion to clean the surface.However, the rust, oxide skin and welding slag on the surface of the steel pipe cannot be removed, so other treatment methods are needed.Tool rust removal Steel pipe surface oxide, rust, welding slag, can use steel wire brush to clean and polish the surface treatment.Tool derusting can be divided into manual and power, manual tool derusting can reach SA

    2 level, power tool derusting can reach Sa3 level.If the surface of steel pipe is attached with a particularly strong oxide skin, it may be impossible to remove the rust with the help of tools, so we need to find other ways.

    3 pickling Common pickling methods include chemistry and electrolysis.But only chemical pickling is used for pipeline corrosion protection.Chemical pickling can achieve a certain degree of cleanliness and roughness on the surface of steel pipe, which is convenient for subsequent anchor lines.Usually as a shot (sand) after reprocessing.

    4 shot blasting for rust removal By high power motor drive the high-speed rotating blades, steel grit, steel shot, segment, minerals and other abrasive wire under the action of centrifugal force on steel pipe surface spray and mass ejection, thoroughly remove rust, oxides and dirt on one hand, on the other hand, steel pipe under the action of abrasive violent impact and friction force, to achieve the required uniform roughness.Among the four treatment methods, shot blasting and derusting is an ideal treatment method for pipe derusting. Generally, shot blasting and derusting are mainly used for inner surface treatment of steel pipe, and shot blasting and derusting are mainly used for outer surface treatment of steel pipe.
