Overview

The complex environment of TBM tunnel construction often presents safety hazards such as gas accumulation and dust explosions. PVC fire-resistant and anti-static ventilation ducts are specially designed for these high-risk environments.

Utilizing a special formula and process, they combine flame-retardant PVC material with static-dissipating technology, ensuring the essential functionality of the ventilation system while providing dual safety protection.

This ventilation duct offers advantages such as airtightness, wear resistance, corrosion resistance, and high compressive strength. Available in lengths of 1m-30m without joints, it meets the long-distance ventilation requirements of TBM tunnel construction.

Product Features

Fire and flame retardancy: Made from Class B flame-retardant PVC mesh, this product offers superior flame retardancy, effectively suppressing flame spread and reducing fire risks during tunnel construction.

Static-dissipating properties: The PVC coating effectively prevents spark discharges caused by static electricity accumulation, significantly reducing the risk of explosions in gaseous environments.

Durability and practicality: Made from high-quality PVC, this hose exhibits excellent tensile strength, high tension, high tear strength, abrasion resistance, and flex resistance. Technical Parameters
