Anti-corrosion steel pipes play a vital role in buried metal bodies
Cangzhou Tianyuan Anti-corrosion Engineering Co., Ltd. hot-selling hotline QQ:
In order to extend the service life of metal bodies buried underground, steel conduits and lead packages Aluminum cables generally have an anti-corrosion layer on the outside. As anti-corrosion coating materials for steel pipes, various insulating asphalt, coal char paint, epoxy asphalt, polyethylene, etc. are used. However, due to the use environment, they will inevitably age after a period of time. In actual pipeline engineering and usage environments, despite careful construction, the anti-corrosion layer cannot be guaranteed to be defect-free. If there is a defect in the anti-corrosion steel pipe layer and the pipe is set at the anode potential, the corrosion current will concentrate on the defective part. From a theoretical or practical experience, it will cause perforation faster than the bare steel pipe. The actual judgment of the quality of underground pipeline coatings is based on the measurement of the total leakage resistance of the pipeline to the earth and its size. In addition, when measuring the ground potential of underground pipelines protected by drainage and other electrical methods, generally according to It is determined by the attenuation state along the pipeline.
How will anti-corrosion steel pipes develop in the country in the future? Anti-corrosion steel pipes include the original asphalt paint anti-corrosion steel pipes and epoxy paint anti-corrosion steel pipes. In recent years, due to the development needs of the market and the continuous improvement of products, anti-corrosion steel pipe products have been introduced. Anti-corrosion steel pipes, cold-wrapped anti-corrosion steel pipes. The anti-corrosion system of anti-corrosion steel pipes is basically long-term. Generally, the design life of anti-corrosion steel pipes is more than one year. Regardless of petroleum asphalt anti-corrosion steel pipe, epoxy coal asphalt anti-corrosion, adhesive cold-wound tape anti-corrosion, or anti-corrosion, various anti-corrosion types are different but each has its own different advantages. Although petroleum asphalt anti-corrosion and epoxy coal asphalt anti-corrosion are used in engineering It will be phased out soon, but it cannot be completely canceled in the short term. Future development will mainly focus on the anti-corrosion type. Because anti-corrosion steel pipes have unique characteristics and characteristics, anti-corrosion steel pipes have great advantages in construction and actual needs.
