Super pipeline products are a kind of products that we often see and use in our life. They also play a very important role in various industries and fields as well as urban construction. With the continuous development and progress of pipeline products, the development of China's pipeline industry has also seen a qualitative leap. Pipelines with different uses appear on the market, meeting the needs of more industries for pipelines.

For the connection method of small calibers with calibers less than 600, the repair free technology lined with stainless steel material is selected, with strong repair force and high mechanical strength. There is no need to repair the internal and external surfaces of super pipes after welding, which solves the problem of repairing the internal and external surfaces at the joints after the pipes are connected. It gives full play to the corrosion resistance of stainless steel and ensures the corrosion resistance of the joint.

After material modification, the ring stiffness of the lined anti-corrosion composite steel pipe reaches okpa, which is significantly higher than the requirement of the relevant national departments that the ring stiffness of buried plastic pipes should be above kPa. The impact strength is high, and the power cable protection pipe can withstand the impact force of kg weight and m height at the temperature of ℃, which fully reflects that the low-temperature impact performance of this material is fully applicable to the requirements under the construction environment.

Super pipe flame retardant PVC and hot-dip plastic steel cable protection pipe materials have good flame retardant properties and can be extinguished immediately after leaving the fire. In particular, the chlorine content of power cable protection pipe material is significantly higher than that of PVC, so the flame retardancy and smoke density index are significantly improved.
