Estimate system.
Background technology
One kind chemistry that the description corrosion of corrosive pipeline phenomenon can be understood as occurring in environment of the material residing for it is anti-
Should, the reaction can cause the loss of pipeline material and cause the even whole pipeline system failure of line member.In pipeline system,
The definition of corrosion is：Based on specific pipeline environments, the chemistry occurred in all metals of pipeline system and nonmetallic materials
The erosion of reaction, electrochemical reaction and microorganism, the reaction can cause the damage and loss of line construction and other materials.Remove
Corrosiveness to the direct destruction of material outside, corrosion failure also can be considered as the Pipeline damage caused by corrosion product.Pipeline
Whether corrosion can spread, and range of scatter has the corrosion resistant of much agents of erosion for depending primarily on corrosive medium and existing pipeline material
Corrosion energy.Temperature, the concentration of corrosive medium and stress state can all influence the degree of corrosive pipeline.
Pipeline is avoided, the guard technology corroded by soil, air and pumped (conveying) medium (oil, natural gas etc.).Conveying oil,
The pipeline of gas is mostly in complicated soil environment, and the medium conveyed also more to be corrosive, thus inner-walls of duct and outer wall
It may all be corroded.The perforation once pipeline is corroded, that is, cause oil, gas leakage, not only make traffic interruptions, and can pollute ring
Border, in some instances it may even be possible to cause fire, causes harm.According to the statistics of U.S.'s pipeline industry, 1975 due to corrosion cause it is straight
Loss is connect up to 600,000,000 dollars.It is therefore prevented that corrosive pipeline is the important content of pipeline engineering.
Although having done the work of more pipeline corrosion protection, pipeline can still corrode for various reasons, accordingly, it would be desirable to periodically
Corrosive pipeline is detected, in the prior art, is generally detected, is examined by pipeline corrosion protection using pipeline corrosion protection detector
