The function of hot dip coated steel pipe
The function of hot-dip plastic steel pipe Hot-dip plastic steel pipe is a new type of anti-corrosion steel produced by fluidized bed dip coating process and one-time film forming process, which is an upgrade to the original plastic coated steel pipe or electrostatic spray pipe. The hot dip molding process ensures better bonding of the paint and pipe material, and can achieve an adhesion force of 5070 kg per square centimeter, and its adhesion will not decay during long-term use. The thickness of the hot-dip coating is about 300 microns, which cannot be achieved by the spraying process. Therefore, the anti-corrosion performance of the hot-dip coating far exceeds the current domestic similar products.
Hot-dip plastic steel pipes are based on the surface treatment of ordinary steel pipes, using medium and working conditions, using polymer materials of different formulations, and uniformly coating them on the metal surface through special equipment. A uniform, dense and smooth plastic coating is formed on the metal surface, and this plastic coating layer becomes a new type of steel-plastic composite pipe, which combines the excellent mechanical properties of steel pipes and the chemical resistance of polymer materials.
Hot-dip plastic steel pipe products use good steel pipe material, which has high mechanical strength, strong pressure bearing capacity, excellent electrical insulation performance, smooth inner and outer surfaces and high hardness, small friction coefficient, good fire resistance, and low water absorption (less than 0.003%) and other advantages. Combining the performance advantages of high-quality steel pipes and nano-coatings, it is widely used in the construction of pipeline systems in the power, mining, municipal, communications, petroleum and chemical industries in various regions of our country.
Here are some of its features:
1. Add antistatic agent to the formula, the inner and outer surface resistance ≤1×10Ω can reach and exceed the relevant industry standards. ——Superior antistatic properties of hot-dip plastic steel pipe
2. The plastic raw materials used in the hot-dip plastic steel pipe are all added with flame retardants, and the flame retardant performance indicators fully meet the standards. – Flame retardant properties of hot-dipped plastic steel pipes
3. After the surface of the hot-dip plastic steel pipe is cured by special treatment, the adhesion of its coating is ≥30N/10mm. ——The coating of hot-dip plastic steel pipe has strong adhesion
4. The coating thickness is greater than 0.5mm, no pinholes, and good corrosion resistance. ——Dense inner and outer resin layers
5. Good coating toughness, high mechanical strength of steel pipe, resistance to external influences such as impact and bending, its performance is far superior to other mine plastic pipes. ——Excellent mechanical properties of hot-dip plastic steel pipe
6. Strong corrosion resistance, no scaling, especially suitable for underground transportation of high-sulfur water and calcium-magnesium-containing plasma water, saving maintenance costs, long service life, much higher than other pipeline materials, and high comprehensive economic benefits. ——The hot-dip plastic steel pipe is corrosion-resistant, does not scale, and has low fluid resistance
The hot-dip plastic steel pipe product overcomes the disadvantage of difficult connection of pure plastic mine materials, and can be connected with the original underground steel pipe and valve by means of flanges, quick joints, etc. as required, with strong interchangeability.
