Which company offers the cheapest tunnel escape pipes? Henan Deyuan Rubber and Plastic Products Co., Ltd. is a professional manufacturer specializing in the production and sale of subway tunnel escape pipes. We produce tunnel escape pipes in two specifications: Φ630*22mm and Φ800*30mm, with reasonable prices, guaranteed quality, and sufficient stock. We welcome everyone to inquire and place orders!
The subway tunnel escape pipes use ultra-high molecular weight polyethylene materials, which have unparalleled impact resistance, compressive strength, wear resistance, aging resistance, lightweight properties, chemical corrosion resistance, are sanitary and non-toxic, and are not easily adhered. They are known abroad as "miracle plastics." Therefore, the new type of tunnel escape pipe - ultra-high molecular weight polyethylene has a wide range of application prospects in fields such as machinery, transportation, textiles, papermaking, mining, agriculture, and chemicals.Which company offers the cheapest tunnel escape pipes?
Tunnel escape pipe: The specification is Φ800*30, and its main parameters are: yield strength σ1=3.7GPa, elastic modulus: E1=700MPa; Poisson's ratio ν1=0.42; density: ρ1=950kg/m3.
The impact test specimen is a block of granite, with the initial selected block diameter of 0.67m. The rock parameters are: elastic modulus E2=40GPa, Poisson's ratio ν2=0.2, density ρ2=2500kg/m3. The weight of the rock block W=400kg. The limit values of the height H from the center of the tunnel and the top of the side to the top of the circular pipe are set at 7m and 5m, respectively. The block is freely released, and impacts are performed on the tunnel escape pipe and the steel pipe. The falling speeds can be calculated according to the conservation of energy, which are v1=11.7m/s and v1=9.9m/s, respectively. Different wall thicknesses H of the circular pipe are calculated, and the impact deformation values of pipes with different wall thickness sizes are obtained.
From the results, it can be seen that the impact energy of the stone block dropped from a height of 10m is very large. At the same time, the Yunnan φ800 ultra-high molecular weight escape pipe has extremely high impact resistance, and external impacts cannot cause it to rupture. Moreover, it has excellent toughness and the ability to absorb impact energy, allowing it to absorb most of the impact energy during the impact process, reducing damage to the pipe. The impact resistance of steel pipes is inferior to that of tunnel escape pipes, and they deform after being hit by stones, making recovery difficult.Which company offers the cheapest tunnel escape pipes?
Conclusion: For the first time, the subway tunnel escape pipe has been used to design the emergency rescue passage for tunnel firefighting. At the same time, the structural dimensions of the tunnel escape pipe conform to ergonomic principles, have a simple structure, and are easy to assemble and disassemble. Subsequently, through comparative impact resistance experiments between the tunnel escape pipe and steel pipe, the reliability of the tunnel escape pipe for emergency rescue in highway tunnels was verified.
The raw materials are uniformly provided by the Shanghai Chemical Research Institute, with a stable molecular weight greater than 2.5 million and rich experience.
Huge scale: covering an area of 2000 acres, with 31 production lines for ultra-high pipes, producing 24 hours a day.
After-sales service: One-year warranty, providing measurement and installation after-sales service.
