APPLICATION

icon Petroleum
Oilway products are applied in crude oil transportation, refining equipment, and storage tank systems. Through high-pressure and corrosion-resistant valve solutions, they ensure the efficiency and safety of oil and gas transmission, and help stabilize the operation of oil fields and refineries.
icon Gas
For long-distance pipelines, LNG liquefaction, and urban gas scenarios, Oilway uses zero leakage sealing and ultra-low temperature adaptability technology to ensure the safety of natural gas transportation and reduce leakage and environmental risks.
icon Chemical
For corrosive media, high-temperature reactions, and fine chemical processes, Oilway provides valve systems with high sealing and acid and alkali resistance to ensure the continuity of chemical production and environmental safety.
icon Power
In the boiler system, steam pipeline network, and desulfurization and denitrification process, Oilway optimizes thermal energy management through high-temperature and high-pressure resistant valves, improves power plant operating efficiency, and supports environmental emissions.
icon Mining
Used for slurry transportation, tailings treatment, and acidic wastewater scenarios, Oilway uses wear-resistant and corrosion-resistant valve technology to improve mineral processing efficiency, reduce equipment losses, and meet mining environmental requirements.
