What are the main application scenarios of large-diameter rubber hoses?

1. Industrial Field Petrochemical & Energy For conveying crude oil, diesel, lubricating oil and other media; oil-resistant rubber hoses can resist chemical corrosion. Fire water supply or high-pressure fluid transmission on offshore oil and gas platforms. Chemical Industry For conveying acid-base solutions and chemical reagents; special rubber hoses with anti-corrosion linings (such as PTFE) are required. Mining & Metallurgy Used for slurry and mud transportation; wear-resistant rubber hoses can withstand highly abrasive environments. Conveying cooling water or steam in high-temperature scenarios (high-temperature resistant materials required). 2. Construction Engineering Concrete Conveying Large-diameter hoses (e.g., above DN150) for pump trucks to deliver concrete, requiring both wear resistance and pressure resistance. Drainage & Flood Control Temporary drainage systems (e.g., construction sites, tunnels); tear-resistant rubber hoses allow rapid deployment. Ventilation Systems Flame-retardant rubber hoses for temporary smoke exhaust or air supply, commonly used in fire emergency situations. 3. Agriculture & Irrigation Farmland Irrigation Large-flow water conveyance; weather-resistant hoses adapt to outdoor ultraviolet rays and temperature differences. Pesticide Spraying & Fertilization Special hoses with chemical corrosion resistance are required to avoid erosion by chemicals.
