Direct supply of ultra-high escape pipes from the manufacturer - Gansu escape pipes

In order to strengthen safety management during tunnel construction and ensure the personal safety of construction personnel during tunnel excavation, according to the Ministry of Railways' "Guidance on Emergency Rescue in Railway Tunnel Construction" (Railway Construction [2010] No. 88) and the actual surrounding rock conditions of the tunnel in the segment, the following requirements for the installation of escape pipelines during tunnel construction are outlined:

1.Escape pipelines should be pre-installed in construction areas of tunnels with surrounding rock grades IV, V, and VI.

2. The pipeline should use ultra-high escape pipes with a diameter of φ630～φ800mm, and the wall thickness must not be less than 30mm. It should be arranged from the lining working face to a suitable location within 20m of the excavation face, with a working rope reserved inside the pipe for easy escape, rescue, communication, and transportation of various items.

3. The longitudinal connection of the ultra-high escape pipes should use a chain connection method to prevent separation during collapses.

All units receiving this notice must pay close attention, set up escape pipelines according to the notice requirements, and ensure that they can effectively function after an accident. The Safety Quality Department of the Project Management Office will conduct follow-up inspections on this work, and units that fail to implement the requirements will be punished according to the situation.

Direct supply of ultra-high escape pipes from the manufacturer - Gansu escape pipes provides extremely reliable protection for emergency rescue in highway tunnel firefighting; the pipe has high ring stiffness, good pressure resistance, and is not easily deformed. In case of a collapse during highway tunnel firefighting, its bearing capacity and resistance to environmental damage far exceed that of ordinary pipes.

Direct supply of ultra-high escape pipes from the manufacturer - Gansu escape pipes materials should be lightweight, easy to disassemble and transport; the pipes have good toughness and high impact strength. When subjected to strong external forces, they deform instantly, absorbing a large amount of impact energy, and then quickly return to their original shape, providing extremely reliable protection for emergency rescue in highway tunnel firefighting; the pipe has high ring stiffness, good pressure resistance, and is not easily deformed. In case of a collapse during highway tunnel firefighting, its bearing capacity and resistance to environmental damage far exceed that of ordinary pipes. The transportation department has designed the emergency rescue passageway for highway tunnel firefighting using new materials (ultra-high molecular weight polyethylene). At the same time, the structure dimensions of the new emergency rescue passage conform to ergonomic principles, with a simple structure that is easy to assemble and disassemble. Subsequently, comparative tests of impact resistance between tunnel escape ultra-high molecular weight polyethylene pipes and steel pipes have verified the reliability of the application of ultra-high molecular weight polyethylene pipes in highway tunnel firefighting emergency rescue.

The ultra-high molecular weight polyethylene pipes produced by our company—safety escape pipes, tunnel escape pipes are thermoplastic engineering plastics with an average molecular weight greater than 2 million, polymerized from ethylene and butadiene monomers under the action of catalysts. This material has superior comprehensive performance, including wear resistance, low-temperature resistance, corrosion resistance, self-lubrication, and impact resistance, ranking high among all plastics. It can work for a long time under conditions of -269 to +80℃ and is known as 'amazing' engineering plastic.

1. The ultra-high molecular weight polyethylene pipes—safety escape pipes have extremely high impact resistance:

At room temperature, it is twice that of PC, five times that of ABS, eight times that of POM and PBT, and ten times that of PE100. Repeated impacts result in even higher surface hardness and excellent resistance to cavitation. Its flexibility allows it to withstand various external shocks without the need for composite steel pipes, making it more reliable than steel pipes.

2. The heat deformation temperature of ultra-high molecular weight polyethylene pipes is higher than that of ordinary plastics by over ten degrees, while cold brittleness is almost nonexistent, and its elongation rate is as high as 400%.

3. Ultra-high molecular weight polyethylene pipes (UHMW-PE)—safety escape pipes are easy to install:

4. The weight of ultra-high pipes per unit length is only 1/8 of that of steel pipes. No anti-corrosion treatment is required, and the direction can be changed according to terrain.

5. Ultra-high molecular weight polyethylene pipes (UHMW-PE)—safety escape pipes have high wear resistance:

The wear resistance is superior to that of polytetrafluoroethylene, nylon, carbon steel, and other materials.
