What is the method for extending the service life of ASTM A106 seamless steel pipes?

For ASTM A106 seamless steel pipes, various difficulties arise when selecting them. It is not that the price is high, that is to say, the price is cheap, or that the quality of ASTM A106 seamless steel pipes is not satisfactory. Overall, it means that the trading volume is relatively low. There is still a reason for the difficulty in the service life of ASTM A106 seamless steel pipes when purchasing, and many customers have also come to understand. The seamless steel pipe factory can improve and increase the service life of ASTM A106 seamless steel pipes. The common method is:

The first method is to apply rust prevention treatment to the square tube. When applying rust prevention treatment to the square tube, it is crucial to use a steel brush to polish and polish its surface. This method can effectively remove loose or raised rust marks on the surface of the square tube.

The second method is to clean the surface of the square tube. During the cleaning process, organic solvents or solvents must be used to clean the surface, which exceeds the effectiveness of oil and dust removal. This type of method is only suitable for removing vegetable oils and dust on the surface of the square tube, which cannot remove rust and air oxide scale. Therefore, in anti-corrosion manufacturing, this type of method is only used as an auxiliary method.

The third method is to carry out acid pickling and passivation on the square tube. When conducting acid pickling and passivation on on the square tube, two methods are used: organic chemistry and electrolysis. These two methods will remove the air oxide skin on the square tube pipeline.
