Second, the pull tube performance characteristics:
1, excellent physical properties. High-density polyethylene has good rigidity, strength, but also has good flexibility, creep resistance, and more high-density polyethylene hot melt connection characteristics of excellent features conducive to the installation of plastic pipe.
2, corrosion-resistant, long service life, in China's coastal areas, high groundwater levels, land humidity, and PE tube resistant to a variety of chemical media erosion, without preservative treatment. In addition, it does not promote the growth of algae, bacteria or fungi, the service life of up to 100 years.
3. Hot Wrapping Molten seam of high quality, extruded from the extruder die in the molten state of the flat material belt and cover tape, according to the predetermined position evenly wrapped in the heated drum mold to ensure that the structure Tube welding seam quality, pipe using air cooling, material cooling uniform. In particular, the structural design of the flat material with the weld seam is covered by tape covered support tube to improve the overall product anti-pressure capacity. The horizontal layer of the pipe and the reinforcing structure layer are welded in the molten state, the quality of the welding seam is high, there is no internal stress, and the overall strength of the pipe is high.
4, flexible ring
Plastic pipe is a flexible pipe, under external pressure load, flexible pipe and rigid pipe to withstand the load mechanism is completely different. Flexible pipe in the pressure before the destruction, there may be greater deformation, while the rigid pipe by the external pressure before the collapse is not likely to have a greater deformation. When the rigid tube is subjected to external pressure, the load is completely transferred to the bottom of the tube bed through the pipe wall, bending moment is generated in the pipe wall. As the pipe diameter increases, the bending moment and stress of the pipe wall sharply increase, Concrete drainage pipe often need to add steel: while the flexible pipe deformation before deformation under pressure lateral expansion, the pipe around the backfill soil can play to prevent the deformation and expansion of flexible pipe role, the external pressure load is passed and apportioned Go to the surrounding backfill. Therefore, under the same external pressure, the stress in the wall of the flexible pipe is smaller, and it will bear the load with the surrounding backfill soil. The pipe and soil work together. Therefore, the plastic buried drainage pipe and rigid concrete pipe without the same strength and stiffness, reasonable stiffness, is fully meet the requirements, which has been confirmed by the application of developed countries in Europe overcast.

4. Toughness, good flexibility.
PE pipe is a highly ductile pipe with an elongation at break of more than 500%, very good adaptability to uneven subsidence and misalignment of the pipe foundation and good earthquake resistance, so it is most suitable for use in areas with seismic hazards and worldwide practice PE pipe is the best shock proof pipeline. It has been reported that the PE pipe and water supply pipe were the only undamaged pipes in the 1995 Kobe earthquake in Japan. In addition, the flexibility of PE pipe is PE pipe can be coiled (especially small diameter PE pipe), reducing the number of connecting pipe fittings. The trend of PE pipe is easy to change according to the requirements of construction method. During construction, it can bypass the obstacle within the allowable bending radius of the pipe to reduce the construction difficulty.

5, large circulation capacity, cost-effective. PE pipe wall smooth, non-scaling. PE pipe surface roughness equivalent absolute ratio of 1/20 steel pipe, the same diameter, the same length, the same pressure PE pipe flow capacity of about 30% larger than the steel, so obvious economic advantages. Compared with the metal pipe, PE pipe can reduce the project investment by about one-third (larger than the diameter of 200 mm pipe costs slightly higher), coil can be small diameter pipe, can further reduce project costs.

6, excellent installation performance, pipe connections used in the socket embedded fused fuse socket with the same material fused technology, high quality connections. Can be 100% leak-free, to ensure the same life of the pipeline system and operational safety. At the same time, due to the light weight of other products under the same application conditions, the product is easy to transport, convenient and quick to construct, and can reduce the construction cost. In the application range, it can be directly applied without concrete cushion and concrete pipe trench , Basically do excavation while under the tube, backfill, simplifying the construction process and shorten the construction period. In engineering acceptance, the use of closed-air test instead of closed water test, not only speed up the acceptance rate, but also closed the water test complicated work and a large number of test costs.

 
7, good sealing. PE pipe itself welded connection (hot melt or fused), in essence, to ensure that the interface material, the structure and the identity of the pipe itself to achieve the integration of pipe joints and pipe. Its interface tensile strength and burst strength are higher than the pipe body, which can effectively resist the axial stress generated by the internal stress of the hoop stress. As a result, there is no risk of leaks caused by the twisting of the joints compared to rubber rings or other mechanical joints and the sealing performance is very good.
 

 
8, good resistance to stress cracking: PE pipe with a low notch sensitivity, high anti-shear strength of the section of the anti-tracking ability, resistance to environmental stress is very prominent.
9, low temperature impact resistance: PE pipe low temperature embrittlement temperature is very low, can be -60 degrees Celsius temperature range of safe use. In the northern part of our country, when laying polyethylene in the field in the winter, there is an experience that it is unsuitable for paving work below zero because the polyethylene pipe is easy to rupture.
10, good wear resistance. Polyethylene pipe and steel wear resistance comparison experiments show that: its wear resistance is 4 times the steel pipe.

 
11, has a good ability to resist 222 scratches. Studies have shown that PE grade PE tube better resistance to SCG ability and scratch resistance. PE100 grade pipe is more excellent scratch resistance.
12, a good resistance to rapid crack transfer ability. Cracking is cracking occurs in the pipe, the crack is transmitted at a fast speed, and the pipeline may be damaged in an instant, and the consequences can be disastrous. Practice shows that the plastic pipe in the PE pipe resistance to crack transmission ability stronger than other pipelines.
13, winding pipe material, high-density polyethylene and polypropylene can be 100% recycled.
