Most of the water pipes in the urban sewage treatment project are buried steel pipes. The corrosion problem is a major problem in the sewage treatment project. The quality and life of the buried water pipelines directly affect the whole project. Therefore, Schneider anti-corrosion coating experts on the long-term anti-corrosion treatment of sewage treatment summary, do a good job in urban sewage treatment works buried pipeline corrosion is essential.

1. Features of buried pipelines

    1.1 Corrosion characteristics: urban sewage treatment works in the pipeline corrosion is mainly soil erosion, which is characterized by decentralized pipeline layout, soil conditions and complex corrosion mechanism is complex. Soil corrosion in the soil of salt, water, oxygen and other steel pipe formed by the electrochemical corrosion, microbial erosion. As the city underground electrical facilities, the cable is more intensive, stray current corrosion is also more serious, through the pipeline near the factory can even be subject to acid or alkali chemical corrosion.

    1.2 force characteristics: urban buried pipeline often through roads, buildings, rivers, etc., the pressure situation is complicated. In addition, in the pipeline buried backfill process may be subject to the impact of sand and crushing damage.

    1.3 Difficulty in repair: buried pipes once damaged by corrosion is not easy to check and repair, corrosion is intensified. In the maintenance often lead to environmental damage. Because of this feature, buried pipe and corrosion design life is generally required in 20-30 years.

2. Coating requirements: According to the characteristics of urban sewage pipes, pipeline coatings should be able to meet the following basic requirements:

    2.1 high adhesion, good resistance to chemical corrosion.

    2.2 good insulation performance and compactness, to prevent electrochemical and stray current corrosion.

    2.3 resistant to bacterial corrosion.

    2.4 have a certain degree of mechanical strength, to prevent the handling and burial process by mechanical damage.

    2.5 construction is simple, safe, to meet the site construction requirements.

    In addition, there are some special requirements in special areas, such as cold resistance.

3. Common anti-corrosion methods: available with urban sewage pipeline corrosion method has the following:

    3.1 petroleum asphalt - glass fiber cloth coating: This anti-corrosion method used in the pipeline more, is now eliminated. The disadvantage is not resistant to bacterial corrosion, poor physical properties, poor construction environment.

    3.2 chlorosulfonated polyethylene coating - glass fiber cloth coating: This method requires high surface treatment, thin coating, low mechanical strength. Now has been in the ranks of the elimination.

    3.3 SNT-509 inorganic anti-corrosion coating for long-term anti-corrosion: At present, our company is recommended SNT-509 acid and alkali anti-corrosion coating, the use of SNT-509 acid and alkali anti-corrosion coating This material construction has a convenient construction, low cost, Good performance and so on. Brush SNT-509 acid and alkali anti-corrosion coating is a convenient anti-corrosion technology, anti-corrosion effect is good, can monitor the operation and corrosion of the pipeline. Industrial pipes and long-distance pipeline applications a lot, and the effect is good.

4.SNT-509 acid and alkali anti-corrosion coating Description:

    Zibo Schneider Anticorrosive Technology Co., Ltd. R & D and production of SNT-509 acid and alkali anti-corrosion coating, the use of PH value of 1-12 in the acid and alkali, solvent gas, solution and acid and alkali, corrosive media can change Corrosion corrosion-resistant, for organic acids, inorganic acid, salt and alkaline, organic solvent corrosion environment, special anti-corrosion coatings, effective to prevent electrochemical and chemical corrosion, long-term protection of the substrate.
