The type of
anti-corrosion steel pipe should be selected according to the working pressure, use, its environment and the material to be transported. Ordinary-grade TPEP anti-corrosion steel pipes are classified according to thickness, thin steel plates are 4 mm (thinnest 0.2 mm), medium-thick steel plates are 4-60 mm, and extra-thick steel plates are 60-115 mm. The substrate of the buried anti-corrosion steel pipe undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc and steel pipe substrate. Therefore, it has strong corrosion resistance. Sand discharge steel pipe galvanized pipes are widely used, in addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, oil, etc., they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and oil heating for chemical coking equipment Tubes for condensers, condensing coolers, coal distillation wash oil exchangers, trestle piles, and support tubes for mine tunnels, etc. At present, the service life of the pipeline system design is required to be more than 30 years. At the same time, we should continue to reduce the number of vehicle maintenance to ensure the everyday life and safe management of the pipeline. The construction party should attach great importance to it. With the development of modern information technology in China, the anti-corrosion materials purchased should have the following advantages:
1. Convenience in construction: Convenience in construction means that the steps are simplified and convenient, and both processing plants and sites can be used for construction.
2. Longer service life: Longer service life. Of course, it is hoped to upgrade from the original design life to a longer-term one, to save maintenance costs such as replacement.
3. Cost management economy: cost management economy means that the product service quality and service life can be proportional to the investment cost. In simple terms, it means high quality and low price.
4. Conforming to environmental protection: In line with the progress of the times, environmental protection requirements are becoming more and more stringent. Taking into account health, safety, and environmental factors, products that cannot meet environmental protection requirements will be phased out. Builders must actively pay attention to environmental protection issues, and then choose high-quality materials. The anti-corrosion protection system for corrosion-resistant steel is long-term, and it takes a long time to know the actual effect, no matter whether petroleum asphalt, coal tar enamel paint, epoxy coal tar pitch, cold tape, FBE PE powder or three-pass Long-term real testing of materials throughout the development process has different advantages, although in the protection project petroleum asphalt tar enamel epoxy coal tar pitch can not be eliminated in the short term, the future trend should melt the epoxy powder, 3PE, polyethylene up / polypropylene tape Cold mainstream products.
