Sinohydr GAS300 Gas Hose is a specialized industrial hose designed for safe and reliable gas transfer in mining and industrial applications. Manufactured to HG/T2540-93 standards, this antistatic gas hose features a comprehensive five-layer construction with integrated antistatic copper wire, making it ideal for use in potentially explosive environments. With a 3:1 safety factor and an operating temperature range of -20°C to 80°C, our mining gas drainage hose delivers exceptional safety, performance, and durability in the most demanding conditions.
Our underground gas hose is constructed with a nitrile rubber (NBR) inner tube that provides excellent resistance to gases and hydrocarbons. The reinforcement layer combines high tensile textile cord, helix steel wire, and continuous antistatic copper wire, ensuring both structural integrity and electrical conductivity. The NBR+CR outer cover offers superior flame retardancy, abrasion resistance, and weather protection, making it suitable for use in harsh mining environments. Available in 10 standard sizes from 19mm to 203mm inner diameter, the GAS300 industrial gas hose can be customized to meet your specific requirements.
The integrated continuous copper antistatic wire ensures complete electrical conductivity along the entire length of the hose, preventing the buildup of static electricity that could ignite flammable gases. This critical safety feature makes our antistatic gas transfer hose essential for use in explosive atmospheres.
The NBR+CR outer cover is formulated with flame-retardant additives that slow the spread of fire and reduce smoke generation. This enhanced safety feature provides additional protection in mining and industrial environments where fire hazards exist.
The combination of high tensile textile cord and helix steel wire reinforcement provides exceptional strength and resistance to kinking, crushing, and abrasion. This robust construction ensures the hose can withstand the rigors of underground mining operations.
With a 3:1 safety factor and rigorous quality testing, our coal mine gas drainage hose provides reliable performance and peace of mind in critical safety applications. All hoses are manufactured to strict industry standards and undergo thorough inspection before shipment.
