3 PE anticorrosive pipe
The 3PE epoxy powder composite steel pipe (also known as TPEP anti-corrosion pipe) is an upgrade product on the basis of the epoxy composite steel pipe in the outer polyethylene, which is the most advanced anti-corrosion form of buried long distance pipeline at present. The self-developed fourth-generation large-diameter pipeline's new anti-corrosion outer wall adopts thermal fusion and winding process to form a three-layer structure anti-corrosion layer with the bottom epoxy resin, the middle adhesive and the outer polyethylene. The inner wall adopts thermal spraying epoxy powder for anti-corrosion, and the powder is evenly coated on the surface of the pipe body after being heated and melted at high temperature. At the same time, it has high strength of epoxy, low water absorption of PE and good softness of hot melt adhesive, with high anti-corrosion reliability.
1 at the end of glue. Before extruding the polyethylene coating, a sealing rubber layer should be applied to the pipe surface. The performance index of base gum is based on the hot melt adhesive of asphalt type used before. National standards on the base of the softening point, heating loss, needle penetration, thermal decomposition temperature, self-repair, shear strength, peel strength, and so on. However, it is proved that the adhesive still has many disadvantages, such as low temperature resistance and poor bonding performance. Some foreign people use butyl glue and the latest resin glue, and domestic base glue is one of the key research topics.
2 polyethylene. The density of polyethylene can range from 0, 91 to 0, 96g /c. The performance is different because of the different densities. Since there is no short bifurcation in high density polyethylene, its junction bii, degree, secondary strength, fracture rate, tear strength, drug resistance is much better than low density polyethylene, which can produce corrosion coatings with different properties and different prices according to the needs of users. High density polyethylene coated pipe (Huang Jiake) the applicable temperature below so ℃, bottom density polyethylene coated pipe (green jacket) the applicable temperature below 60 ℃.
3. Production method. Polyethylene anticorrosive coating used flow dipping process and powder dispersing and melting process, etc. Recently, the production method is basically extrusion method. Bibian of small diameter (15-800mm) is the adhesive circular mould method (with protective layer), and bibian of human diameter (400-1600mm) is the tight t-mould method (no protective layer, single layer). Recently, the use of close - fitting method on small and medium diameter pipe is increasing gradually. In the future, this method may be widely used on anti-corrosion steel pipe
- Q: What is the role of steel pipes in the mining and extraction of minerals?
- Steel pipes play a crucial role in the mining and extraction of minerals. They are widely used in various mining operations to transport water, slurry, and other fluids, as well as to provide structural support and ventilation in underground mines. One of the primary uses of steel pipes in mining is for transporting water or slurry. Water is essential in the mining process for various purposes, such as dust suppression, ore processing, and site rehabilitation. Steel pipes are used to create a network of pipelines that transport water from a source, such as a dam or reservoir, to different areas within the mine site. Similarly, slurry, a mixture of water and crushed minerals, is often transported through steel pipes to processing plants or tailings dams. Steel pipes also play a critical role in providing structural support in underground mines. Underground mining operations require tunnels and shafts to access valuable mineral deposits. These tunnels and shafts need to be reinforced to withstand the immense pressure exerted by the surrounding rock and prevent collapses. Steel pipes are used as support structures, such as roof bolts and rock bolts, to reinforce the walls and roofs of these underground excavations, ensuring the safety of miners and the stability of the mine structure. Additionally, steel pipes are used for ventilation systems in underground mines. Proper ventilation is vital in mining to ensure a constant supply of fresh air, remove harmful gases, and control temperature and humidity levels. Steel pipes are used to create ventilation shafts and ducts that facilitate the flow of air throughout the mine. This helps maintain a safe and healthy working environment for miners by preventing the buildup of toxic gases, dust, and heat. In summary, steel pipes are indispensable in the mining and extraction of minerals. They are used for transporting water, slurry, and other fluids, providing structural support in underground mines, and facilitating ventilation systems. Without steel pipes, the efficient and safe extraction of minerals from mines would be significantly hindered.

- Q: What is the difference between hot-finished and cold-finished steel pipes?
- Distinguishing hot-finished and cold-finished steel pipes can be done by examining their manufacturing processes, which lead to different characteristics and applications. To create hot-finished steel pipes, a solid steel billet is heated to a high temperature and then pierced to form a hollow tube. This process, known as hot rolling, ensures that the steel is easily shaped and malleable. As a result, hot-finished steel pipes have rough surfaces and rounded edges. They are generally larger in diameter and have thicker walls. These pipes are commonly utilized in industries that demand high strength and pressure resistance, like the oil and gas sector, structural projects, and heavy machinery manufacturing. On the other hand, cold-finished steel pipes are produced using a process called cold drawing. This involves pulling the hot-finished steel pipe through a die at room temperature to reduce its diameter and achieve the desired shape. The cold drawing process yields a more precise and smoother finish for the steel pipes. Cold-finished steel pipes possess smoother surfaces and sharper edges compared to their hot-finished counterparts. They are typically smaller in diameter and have thinner walls. Cold-finished steel pipes are commonly applied in industries that require accurate dimensions, such as automotive part manufacturing, construction component fabrication, and machinery production. In conclusion, the primary disparity between hot-finished and cold-finished steel pipes stems from their manufacturing processes, resulting in variations in surface finish, dimensions, and applications. Hot-finished pipes are suitable for applications that demand high strength and pressure resistance, while cold-finished pipes are ideal for applications that require precise dimensions and smooth surfaces.
