PE tube should be familiar to all of us, it is widely used in our life. With the improvement of people’s living standard, people’s requirements for products are also increasing rapidly, and its technology is becoming more and more mature. Next, I will introduce the flip molding technology of PE tube.
In view of some existing problems, combining with numerical simulation technology, the turning forming of products in the factory was studied. Firstly, on the basis of consulting a large number of technical data, the basic theory of turning forming, the characteristics of common pipe fitting turning die, the instability mode of PE pipe fitting turning forming, and the two common instability modes of axial compression are discussed. The tear instability of tube end is analyzed simply.
Secondly, the turning forming process of common pipe fitting turning dies such as cone die, round corner die and groove die is studied theoretically. The deformation process of various pipe fitting turning dies and the influence of the main parameters on the forming process are analyzed, and some laws of the influence of various parameters on the forming process are put forward.
On the basis of the above research, aiming at the defects of the traditional vehicle tube die, the structure of the “booster” vehicle tube die was put forward, the deformation process of the vehicle tube was simulated, and the influence of various parameters on the forming process was studied. Analysis, a preliminary summary of some formation rules. Compared with the traditional PE pipe fitting turning forming structure, the “SUPERcharger” pipe fitting turning die not only improves the geometric precision of pipe fitting turning, but also greatly improves the formability of pipe billet.
The PE pipe system is connected by electrothermal melt, and the joint strength is higher than the pipe body. Low temperature impact resistance, low temperature embrittering temperature of polyethylene is very low, can be used in the range of -60℃~60℃. In winter construction, due to the good impact resistance of the material, the pipe brittle crack will not occur. Good stress cracking resistance, PE pipe has low notch sensitivity, high shear strength and excellent scratch resistance, environmental stress cracking performance is also very outstanding.
Good chemical corrosion resistance, PE pipe can withstand a variety of chemical media corrosion, chemical substances in the soil will not cause any degradation of the pipe. Polyethylene is an electrical insulator, so it will not rot, rust or electrochemical corrosion; It also does not promote the growth of algae, bacteria or fungi.
Aging resistance, long service life, containing 2~2.5% carbon black polyethylene pipe evenly distributed, can be stored outdoors or used for 50 years, not damaged by ultraviolet radiation.
PE tube has good wear resistance. The wear resistance of PE pipe and steel pipe is 4 times that of steel pipe. In mud transport, pipes have better wear resistance than steel tubes, which means longer service life and better economy
Through the above introduction, you should have a certain understanding of PE tube turnover molding technology, if you want to know more about the product information, please pay attention to our website update, hope to help you.
