Onshore lines are typically buried to protect them from external damage and to meet regulatory requirements, requiring precise trenching and compaction. Smart pigs, or pipeline inspection gauges, are deployed internally to detect anomalies such as corrosion, cracks, and geometric deformations.
Onshore Oil Pipework Trenching Standards and Best Practices
Material Selection and Steel Grades The choice of material for oil pipework is dictated by the specific application, pressure requirements, and the chemical composition of the transported fluid. Higher grades like X80 and X100 are employed in challenging environments, offering greater resilience against high pressures and potential ground movement.
Once fabricated, pipes are joined in the field using various methods, including gasketed flanges for frequent maintenance sections and fusion welding for permanent, high-integrity connections in transmission lines. Regular hydrostatic testing verifies the pressure containment capability of the system.

Protective Coatings and Corrosion Management Internal and External Protection Corrosion is the primary enemy of oil pipework , necessitating advanced protective measures. Regulatory Compliance and Industry Standards The design, construction, and operation of oil pipework are governed by a stringent framework of international standards and local regulations.
