GAS PIPE
This gas pipe utilizes a special rubber inner liner highly resistant to gas corrosion, perfectly adapted for the delivery of combustible gases such as underground coal mine gas and biogas. It provides excellent airtightness and is highly resistant to gas permeation and leakage. The multi-layer high-strength fiber wrapped reinforcement structure ensures stable pressure containment, effectively resisting gas pressure fluctuations while remaining highly tensile and resistant to cracking. The weather- and abrasion-resistant outer cover protects against dragging by underground rocks, moisture corrosion, and aging. It offers excellent flexibility and is highly resistant to damage when bent. Select models are equipped with an anti-static structure to safely dissipate friction-generated static electricity, completely eliminating the risk of gas explosions. It is primarily used for underground coal mine gas drainage, biogas pool gas delivery, and mine ventilation and exhaust applications.
