The Luoyang Zhengju tunnel escape pipe, made of UHMWPE, can effectively prevent people from being trapped due to tunnel collapse during tunnel construction. It has three outer diameters of 800mm, 860mm and 1000mm, and a wall thickness of 30mm. If you have a project to start and need tunnel escape pipes, please contact me at any time.
