Product advantages
1) High ring stiffness
For ordinary plastic wall wound pipes for underground drainage, the maximum ring stiffness is difficult to exceed SN 8, but the new structure of pipes can easily reach SN8, SN12.5 and SN16, or even higher. On the other hand, this kind of steel-plastic composite pipe with steel pipe as the middle layer and polyethylene plastic inside and outside has very good anti-corrosion performance. Therefore, this composite anticorrosive pipe can be applied to various harsh environments. For example, in some coastal areas, because the soil contains corrosive substances, the working life of concrete pipes will be very short, and it is very desirable to be able to use corrosion-resistant plastic buried drainage pipes. However, in the past, because products without high ring stiffness could not meet the design requirements, metal-reinforced winding structural wall pipes could be used.
2) Save material cost
In addition to these performance improvements, another significant advantage is saving material costs. Compared with other plastic pipes with the same diameter and ring stiffness, the steel belt reinforced polyethylene (PE) spiral corrugated pipe can save nearly half of the material consumption.
Steel tape winding pipe product introduction
Steel tape winding pipe
Polyethylene only accounts for 2/3 of the overall weight of the composite pipe; under the situation of rising plastic prices, this is a very good solution for reducing material costs. The ring stiffness achieved after the thin steel strip is pressed into a steel rib far exceeds the effect produced by a very thick polyethylene structure layer. The required ring stiffness can be easily achieved by appropriately designing the thickness and height of the steel rib. The function of polyethylene in the metal-reinforced winding structure wall pipe is corrosion resistance and abrasion resistance. Therefore, there are not many steel ribs in the metal-reinforced winding structure wall pipe, and the polyethylene does not need much material. Huantong Pipe Industry uses continuous steel belts to press into approximately ^-shaped spiral steel ribs that are wound between the inner and outer layers of thermally welded polyethylene to combine the high rigidity and high strength of the steel with the flexibility, corrosion resistance and wear resistance of polyethylene. Together.
Features
1. Pressure and impact resistance. The ∧-shaped steel belt reinforcement inside the pipe greatly improves the ring stiffness of the pipe.
2. Good economy. Large-caliber pipes of the same specification are lighter in weight than pipes of other materials, convenient for handling, transportation, installation and connection, and low overall cost.
3. Acid and alkali resistance, anti-aging, and will not be corroded by sewage or chemicals. The black pipe is anti-ultraviolet and prolongs its service life.
4. Smooth drainage and sewage, small flow resistance on the inner wall of the pipe, strong water flow capacity and large flow.
5. The connection method is safe and reliable, and it can be used in combination with electric heating, heat shrinkable tape, internal and external extrusion welding, etc., the connection is firm, and the pipe does not leak.
Scope of useedit
1. Municipal engineering drainage and sewage engineering.
2. Various water delivery and irrigation projects in industry and agriculture.
3. Road public works, such as railways, highways, stadiums, etc.
