description
ONSHORE PIPELINE is the core infrastructure for the long-distance transportation of oil, natural gas, water resources, and industrial media on land. They are made of high-strength welded steel pipes (such as LSAW/SSAW/ERW). Through strict material selection, welding processes, and multi-layer anti-corrosion treatments, they ensure safe operation under complex geological and climatic conditions. Their typical design life is 30-50 years, suitable for high-pressure, high-flow transportation scenarios, with advantages such as high efficiency, low loss, and easy maintenance.
