Avoid spiral steel pipe erosion causes
In order to increase the service life of pipeline, pipeline anti-corrosion construction has become an indispensable link in the pipeline production process; With the continuous progress and production of manufacturers, a variety of anti-corrosion spiral steel pipes are on the market, so how can anti-corrosion spiral steel pipes avoid spiral steel pipes being etched
Avoid spiral steel pipe corrosion reasons
One of the most common ways to prevent metal corrosion is to change the structure of the metal. There are many types of metals, and some heavy metals have low chemical activity and are not easy to be eroded by other components, and some metals can be used in combination with other metals to effectively enhance the anti-erosion function
Such as adding chromium, nickel and other raw materials to the general steel to make stainless steel materials, you can get a good anti-corrosion effect
Corrosion prevention spiral steel pipe can be used to prevent corrosion, metal corrosion can also be achieved based on the disposal of corrosive media, this type of method focuses on removing the existence of corrosive media, that is, maintaining the drying of metal equipment, such as often wipe the water on the equipment, avoid the dryer in the precision instrument, adding corrosion inhibitors in the corrosive medium are all belonging to this type of corrosion prevention method.
The electrical safety method of metal safety protection is based on the principle of galvanic cell theory to do a good job of anti-corrosion protection of metal, according to the galvanic cell theory, only need to remove the chemical reaction of the galvanic cell that causes chemical corrosion, you can realize the anti-corrosion of metal.
The electrochemical safety method of metal corrosion can be divided into anode protection and cathodic protection, in which the cathodic protection is more used
Advantages of anti-corrosion spiral pipe
Because the spiral pipe is stacked outdoors, and when it is used, most of it is buried in the ground, so it is easy to corrode and rust, in order to ensure the smooth flow of the pipeline, the spiral pipe is required to have strong corrosion resistance.
Once the pipeline is corroded, it will cause oil and gas leakage, which will not only interrupt the transportation, but also pollute the environment, and may even cause fire, causing harm.
When the pipeline is erected, it is necessary to do anti-corrosion work or directly use anti-corrosion spiral steel pipe. The reason for the corrosion of the pipeline is that the anti-corrosion layer of the pipeline has been destroyed. Once the anti-corrosion layer and the pipe surface are separated, it will naturally cause anti-corrosion failure. This is also the ladder we should choose anti-corrosion spiral pipe when purchasing spiral pipe.
It is mainly to look at the characteristics of the medium around the pipeline, the temperature, and whether the medium around the pipeline is corrosive. Because the corrosiveness of the medium is closely related to the microorganisms contained in the soil. And if it is a long-distance pipeline, the soil environmental properties are more complex.
In addition, the temperature of the environment in which the pipe is located will also affect the corrosion of the spiral pipe, if the temperature is high, the corrosion speed will be accelerated, while the temperature is low, the corrosion speed will be slowed down.
