What kind of anticorrosion coating should be used for spiral steel pipe for the water transmission pipelines? We determine it according to the use and application of water. First of all, let's do the classification of water delivery. We can roughly divide it into two categories: one is industrial water and the other is domestic water. First, let's look at the first category:
Industrial water, as the name implies, refers to the production water of enterprises or wastewater after production. For industrial water requirements are not too strict, water treatment clean does not affect the use of so the application of corrosion is often relatively simple. We choose the cost-saving epoxy coal asphalt anti-corrosion and anticorrosion can be, this kind of anticorrosion operation is simple and affordable and is a good choice. Of course, there is also more stringent industrial water use, such as the pharmaceutical industry. This requirement is stringent and needs to be lined with tetrafluorotic corrosion. Tetrafluoron anti-corrosion anti-oxidation anti-acid and alkali is a more expensive anti-corrosion means. We use polyurea or lined with polyethylene anti-corrosion treatment for low acid and alkali water pipelines.
Domestic water, domestic water is divided into two kinds of water supply and drainage, water supply pipeline is our usual drinking water, and this kind of pipeline requirements are very strict, now the general practice is the inner wall 8710 non-toxic anti-corrosion coating, this coating is non-toxic and non-corrosive, high safety performance. In recent years, we have introduced more advanced plastic coating technology. This process increases the service life of the pipeline to 30-50 years, which greatly increases the service life of the pipeline. Now we are more inclined to this kind of embalming. However, this kind of anticorrosion also has the disadvantage that it needs equipment treatment and cannot be constructed on-site.
Life drainage is also very simple, as long as the pipeline anticorrosion period does not pollute the environment can be increased, so we generally do epoxy coal asphalt anti-corrosion more.
