Hole mesh steel strip PE composite pipe
Hole mesh steel strip PE composite pipe is a new type of composite pipe, which takes cold-rolled strip steel and thermoplastics as raw materials, and use chlorine arc butt welding or plasma spiral welding to form porous wall steel pipes as reinforcements.thin-walled porous steel pipe reinforced by argon arc butt welding and double-sided composite thermoplastic, inside of the thermoplastic there is one steel plant with outer and inner layers. Because the reinforcement is completely covered in plastic through holes, the composite pipe overcomes the respective shortcomings of steel pipe and plastic pipe, and maintains the respective advantages of steel pipe and plastic pipe. It is an ideal application pipeline for civil construction, urban water supply, petrochemical industry, electric power, pharmaceuticals, metallurgy and other industries, and is a public at home and abroad. Recognized as a new high-tech composite pipe.
Industry Application
Civil buildings, petrochemical industry, urban water supply, pharmaceuticals, electric power, metallurgy industry etc..
Main technical performance:
- High strength, low linear expansion performance. Due to the reinforcement of the steel frame, the perforated steel strip plastic composite pipe has higher strength, high rigidity and impact resistance than plastic pipes. At the same time, the restraint effect of the steel frame also makes the perforated steel strip plastic composite pipe have a low line similar to that of the steel pipe. Expansion coefficient and creep resistance.
- Corrosion resistance and wear resistance. The high-density polyethylene material selected for the perforated steel strip plastic composite pipe is a crystalline non-polar polymer material with stable chemical properties, resistance to most acid, alkali salts and organic media, and no electrochemical corrosion. The wear resistance is 5 times higher than that of steel pipes.
- Smooth inner wall and good circulation performance. The inner wall of the perforated steel belt plastic composite pipe is very smooth, and the absolute roughness is only 1/20 of that of the steel pipe. The conveying capacity under the same conditions is about 30% higher than that of the steel pipe.
- Safety performance. The reinforced frame of the perforated steel belt plastic composite pipe and the plastic raw materials are completely contained as a whole through the perforated net, and there is no worry of peeling off the inner and outer walls of the plastic and the steel frame. The electric fusion connection has strong resistance to axial pulling, and the overall reliability of the pipeline is high. Under normal conditions, the service life can reach 50 years.
Pipe specifications
Product advantages
Characteristics: Good rigidity and insufficient flexibility
With a steel plant inside, which strengthen the rigidity and with higher abrasion resistance. Outside of the steel plant, with two piece of high-density polyethylene, ensures the flexibility.
Hygienic performance
The hygienic index and safety of the perforated steel strip composite pipe conform to GB9687 (the sanitary standard of polyethylene products for food packaging) and GB/T17219 (the safety evaluation standard of water delivery equipment and protective materials for drinking water). The best substitute for zinc pipe and ductile iron pipe.
High strength and low linear expansion
Due to the reinforcement of the steel framework, the perforated steel strip plastic composite pipe has higher strength, high rigidity and impact resistance than the plastic pipe. At the same time, the binding effect of the steel plate also makes the perforated steel strip plastic composite pipe Also has low linear expansion coefficient and creep resistance similar to steel pipe.
High ring stiffness and high rigidity
The perforated steel strip plastic composite pipe has high ring stiffness and high rigidity close to that of metal pipes, and is especially suitable for overhead laying of pipe corridors and risers.
