Ultra-High Escape Pipe Direct Supply from Manufacturer | Gansu Escape Pipe

In order to strengthen safety management during tunnel construction and ensure the personal safety of construction personnel during the tunneling process, based on the Ministry of Railways' "Guidelines for Emergency Rescue and Relief in Railway Tunnel Construction" (Rail Construction [2010] No. 88) and the actual surrounding rock conditions of the tunnel section, the following requirements for the installation of escape pipes during tunnel construction are hereby announced:

1.The tunnel construction in the work area should pre-install escape pipes in the surrounding rock sections of levels IV, V, and VI.

2. The pipes should use ultra-high escape pipes with a diameter of φ630～φ800mm, with a wall thickness of no less than 30mm, arranged at an appropriate position within 20m from the excavation face, with a reserved working rope inside the pipe to facilitate 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 disconnection during collapses.

All units must attach great importance to this notice and set up escape pipes according to the requirements of the notice, ensuring that they can effectively function in the event of a closure accident. The Safety and Quality Department of the Project Management Department will track and inspect the implementation of this work and will penalize units that fail to implement the requirements effectively.

Ultra-High Escape Pipe Direct Supply from Manufacturer | Gansu Escape Pipe provides extremely reliable assurance for emergency rescue in highway tunnel fire escape; the pipe has high ring stiffness, good pressure resistance, and is not easily deformed. In the event of a collapse in highway tunnel fires, its load-bearing capacity and resistance to environmental damage far exceed that of ordinary pipes.

Ultra-High Escape Pipe Direct Supply from Manufacturer | Gansu Escape Pipe materials should be lightweight for easy disassembly and handling; the pipe should have good toughness and high impact strength, deforming instantly under strong external impacts, absorbing a large amount of impact energy, and then quickly returning to its original shape, providing extremely reliable assurance for emergency rescue in highway tunnel fire escape; the pipe has high ring stiffness, good pressure resistance, and is not easily deformed. In the event of a collapse in highway tunnel fires, its load-bearing capacity and resistance to environmental damage far exceed that of ordinary pipes. The transportation department uses new materials (ultra-high molecular weight polyethylene) for the design of emergency rescue passages in highway tunnels. 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 disassemble. Subsequently, by conducting impact resistance comparative tests between ultra-high molecular weight polyethylene pipes and steel pipes for tunnel escape, the reliability of using ultra-high molecular weight polyethylene pipes for highway tunnel fire emergency rescue was verified.

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 overall performance, is wear-resistant, low-temperature resistant, corrosion-resistant, self-lubricating, and has high impact resistance among all plastics. It can work long-term under conditions of -269 to +80℃, known as an 'amazing' engineering plastic.

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

At room temperature, it isPC's2's 2 times, ABS's 5 times, POM and PBT's 8 times, and PE100's 10 times. Repeated impacts increase surface hardness significantly and provide excellent cavitation resistance. Its flexibility allows it to withstand various external impacts without the need for composite steel pipes, making it more reliable than steel pipes.

2. Ultra-high molecular weight polyethylene pipes have a heat deformation temperature that exceeds ordinary plastics by several degrees, while cold brittleness is almost negligible, and the elongation rate reaches up to 400%.

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

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

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

Wear resistance is superior to materials such as polytetrafluoroethylene, nylon, and carbon steel.
