Hot dip plastic steel pipe
Hot-dipped plastic steel pipe is based on the surface treatment of ordinary steel pipes, and uses different formulations of polymer materials according to the medium used and working conditions. Apply it evenly on the metal surface through special equipment, and form a uniform, dense and smooth plastic coating on the metal surface after plasticization and curing, becoming a new type of steel-plastic composite pipe. It combines the superior mechanical properties of steel with the chemical corrosion resistance of polymer materials.
The hot-dipping process can ensure that the coating and the pipe have good adhesion, and the adhesion it achieves is 50 to 70 kilograms per square centimeter, and its adhesion will not decrease during long-term use. The coating thickness of the steel pipe is about 300 microns, which cannot be achieved by the spraying process, so its anti-corrosion performance far exceeds the current similar products.
The material used for hot-dipped plastic steel pipe products is high-quality steel. The product has the advantages of high mechanical strength, strong pressure resistance, high inner and outer surface hardness, smooth steel pipe surface, small friction coefficient during use, excellent electrical insulation performance, and good flame retardancy. By combining the performance advantages of high-quality steel pipe and nano-coating, it is mainly used in the construction of pipeline systems in various regions for power transportation, municipal use, communication use, mining transportation and chemical industry.
Features of hot dip plastic steel pipe
1. Excellent antistatic performance of hot-dip plastic steel pipe:
2. Hot-dipped plastic steel pipe has good flame retardant performance
3. The hot-dipped plastic steel pipe coating has strong adhesion. The surface of the steel pipe is specially treated, the process is cured, and the coating adhesion is ≥30N/10mm
4. Dense inner and outer resin layers: the thickness of the coating is more than 0.5 mm, there is no pinhole, and it has excellent corrosion resistance.
5. The coating of hot-dipped plastic steel pipe has good toughness, high mechanical strength of the steel pipe, and has a strong ability to withstand external influences such as impact bending
6. The hot-dipped plastic steel pipe is corrosion-resistant, non-scaling, and has low fluid resistance. It is especially suitable for transporting high-sulfur water quality and water containing calcium and magnesium ions underground, saving maintenance costs. The service life is much higher than other pipes, and the comprehensive economic benefits are high.
7. Self-lubricating property: the inner wall is smooth without scaling, and the conveying resistance is small. Under the same conditions, the conveying capacity can be increased by 30%.
8. Easy and reliable connection
scope of application
Hot-dipped plastic composite steel pipes are suitable for coal mine gas extraction, ventilation systems, fire water supply systems, central air-conditioning HVAC circulating water pipes, industrial water supply and drainage, domestic water supply and drainage, gas and other gas transmission, power threading,chemical pipelines and seawater treatment pipes, etc.
Galvanized pipe
Galvanized pipe is a welded steel tube with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life
Features of galvanized composite steel pipe:
1. High mechanical strength and high ductility;
2. Good connection performance to ensure no leakage;
3. Special sealing of composite pipe end face;
4. The installation technology is relatively traditional and easy to promote;
5. Good hygienic performance, can transport clean water; high temperature resistance, can transport hot water, boiling water;
6. No aging, long service life;
7. Low temperature brittleness, small expansion coefficient;
8. Low purchase price.
scope of application
Galvanized steel pipes are mainly used in drinking water supply pipelines, seawater pipelines, sewage pipelines, shipbuilding pipelines and other water delivery pipelines. The connection method of the pipeline includes special special ring connection, groove connection or thread connection, and the construction process is similar to the groove connection of the steel pipe and the thread connection of the steel pipe.
Both hot-dip plastic steel pipe products and galvanized steel pipe products have the characteristics of high mechanical strength, strong corrosion resistance, convenient installation, convenient connection, high temperature resistance and long service life. The main difference is that in addition to the different materials of the protective layer, the hot-dip plastic steel pipe is coated both inside and outside, while the galvanized steel pipe is only coated with the outer layer.
