The water supply of a city is very large. This caused the tap water to pass through the steel pipe, which would have a great impact on the pipeline. Under such a pressure, ordinary steel pipes are likely to be damaged. However, the spiral steel pipe is different, and its superior toughness determines that the spiral steel pipe can withstand greater pressure. And ordinary steel pipes may be easily rusted. The quality of IPN8710 drinking water pipeline anti-corrosion pipeline is a matter of concern to the purchaser *. Its quality is mainly composed of its own materials, standards, wall thickness, welds and other factors. The quality of the steel pipe is measured under the same material and standard conditions Mainly depends on the wall thickness and the quality of the weld. Due to the very wide range of spiral steel pipe users, the brackets, water pipelines and other projects that we usually see, once the quality of the spiral steel pipe is problematic, these projects will be affected, and the more serious ones will directly affect human safety. At present, the wall thickness of spiral steel pipes in the market is usually lower, so the lower difference range is better than the lower quality, and the pressure bearing capacity is stronger. The quality of the weld is mainly determined by eye or through flaw detection. The weld has no sand holes , Even welding seams are high-quality products.

Anti-corrosion steel pipes for drinking water pipelines refer to steel pipelines that have been processed by anti-corrosion technology, which can effectively prevent or slow down the occurrence of corrosion during chemical or electrochemical reactions during transportation and use. Anti-corrosion steel pipes are classified according to purposes: anti-corrosion steel pipes can be divided into: steel pipes for pipelines, steel pipes for thermal equipment, steel pipes for machinery industry, petroleum, steel pipes for geological drilling, container steel pipes, steel pipes for chemical industry, special-purpose steel pipes, etc. Pipeline water transportation is widely used in developed countries. In fact, the pipeline is used to directly transport water to farmland for irrigation, which effectively avoids water leakage and evaporation loss in the channel. This technology is developing rapidly in northern China. The pipes commonly used in field irrigation in many places are concrete pipes, plastic hard pipes and hoses, metal pipes, etc., so that the water is quickly transferred to the field in a timely manner, without the need to occupy farmland, which effectively improves the efficiency of irrigation and makes Water resources are fully utilized, which plays a great role in agricultural production and ensures the increase of agricultural production. The steel water pipeline produced by our factory adopts epoxy coal asphalt on the outer wall of the pipeline, and the inner wall IPN8710 non-toxic paint is used to prevent corrosion of the pipeline. It effectively avoids the corrosion of the steel pipe during the operation and does not harm the crops.

The transportation water quality is different, the anticorrosion materials are also different, and the anticorrosion effect is more different. It is related to the quality and cost of the anticorrosion insulation steel pipe. Consider the selection and application of anti-corrosion materials and anti-corrosion costs. The performance advantages of TPEP anti-corrosion and heat-insulated steel pipe: good heat insulation performance, heat loss is only% of traditional pipe materials, long-term operation can save a lot of energy, and significantly reduce energy costs. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be buried directly in the frozen ground underground. The service life is up to 3 years, and the correct installation and use can make the maintenance cost of the pipe network extremely low. An alarm system can be set up to automatically detect pipe network leakage faults, accurately indicate the fault location and automatically alarm. The materials and anti-corrosion system of TPEP anti-corrosion and heat-insulating steel pipes are basically long-term ones. It takes a long time to know the actual effect. Now that the country is vigorously developing the energy industry, especially the amount of capital invested in oil and gas pipelines is even greater. Since oil and gas pipelines are easily corroded, more efforts should be made to study anti-corrosion and thermal insulation steel pipes. Now people have proposed to use a new coating to improve its performance. The temperature in our city is cold in winter. Generally, the main pipelines and urban pipeline networks are laid underground, so the anticorrosion requirements for the pipeline network are very high. Good anticorrosion can avoid the leakage of the pipeline network caused by the corrosion of the pipeline and the increase of the internal friction Impeding and polluting water quality, on the contrary, brings great trouble to the pipe network.

If the drinking water pipeline is scaled, the water quality is "secondarily polluted", and the residual chlorine in the water is consumed by organic matter, so the total number increases. There are original bacteria in these and corrosion of the pipeline. These various, some seriously affect the quality of water, and some have exacerbated pipeline corrosion, thereby shortening the service life of the pipeline. Drinking water delivery pipelines are mostly metal pipelines, and metal corrosion is one of the main causes of material failure and destruction. Because buried pipelines are placed in the soil, their operating environment is complex. After the pipelines are corroded and damaged, they will cause pipeline leakage, environmental pollution, serious accidents such as combustion or explosion, and serious waste of resources and energy, which will cause the national economy to suffer. Huge loss. Therefore, studying the corrosion mechanism and taking effective protective measures are of great significance to economic construction. In summary, the effective detection and protection of the outer anti-corrosion layer of the directly buried steel water supply pipeline can promptly discover the damage points of the outer anti-corrosion layer, and promptly adopt scientific and effective measures to the damage points of the damaged outer anti-corrosion layer. Carry out repairs to ensure the safe operation of the water supply pipeline in good condition. Under the trend of continuous development and improvement of scientific and technological level, the company's detection technology and equipment for the external corrosion protection layer of directly buried steel water supply pipelines are becoming more and more perfect, the materials used are becoming more and more high-quality, and its detection procedures are also increasing The more standardized, these improvements provide a guarantee for improving the safety management level of buried gas pipelines, and will play a more important role in improving the company's overall operation efficiency of water supply pipelines.

How to develop anti-corrosion steel pipes for drinking water pipelines in China in the future. Anti-corrosion steel pipes include original asphalt paint anti-corrosion steel pipes and epoxy paint anti-corrosion steel pipes. In recent years, due to market development needs and continuous improvement of engineering products, anti-corrosion steel pipe products have launched 3PE Anti-corrosion steel pipe, anti-corrosion steel pipe with cold winding. The anti-corrosion system of anti-corrosion steel pipes is basically a long-term effect, and the design life of general anti-corrosion steel pipes is more than 30 years. Regardless of petroleum asphalt anti-corrosion steel pipe, epoxy coal asphalt anti-corrosion, adhesive cold-winding belt anti-corrosion, or 3PE anti-corrosion, each type of anti-corrosion is different but each has its own different advantages. Although petroleum asphalt anti-corrosion, epoxy coal asphalt anti-corrosion, in engineering It is about to be eliminated in use, but it cannot be completely cancelled in a short period of time. The future development will mainly be based on the type of PE corrosion protection. Because of the characteristics and characteristics of anti-corrosion steel pipes, anti-corrosion steel pipes have great advantages in construction and actual needs. *, The construction of anti-corrosion steel pipe is convenient, the steps are simplified and convenient, and the construction can be carried out in the processing plant and on site. IPN8710 ordinary drinking water pipes are plagued by corrosion defects, so the use of ordinary steel pipes is continuously shrinking. The corrosion is mainly caused by the oxidation of the steel pipe, and the metal will be oxidized. Even if it is an alloy, when the conditions are certain, the alloy steel pipe will still be oxidized.
