304 Line Pipe

Pipeline conduits are specialized tubular materials used for transporting various media (oil, gas, water, chemical fluids, slurries, etc.) over long distances or in industrial settings. Their core characteristics include excellent pressure resistance, corrosion resistance, fatigue resistance, and long-term operational stability. They must be adaptable to different media characteristics (such as corrosion, high temperature, and high pressure) and laying environments (such as underground, seabed, desert, and high-altitude cold regions). They are indispensable core transport equipment in energy, chemical, municipal, and mining industries.
