GB/T 40874-2021

This standard provides guidelines for ensuring pipelines are fully filled during the bulk transfer of crude petroleum and petroleum products, minimizing air pockets and vapor voids that can cause measurement inaccuracies or operational hazards. It is applied in the petroleum industry during loading, unloading, and inter-tank transfers at terminals, refineries, and storage facilities where custody transfer or inventory control relies on precise volumetric measurement. The guidelines help operators achieve consistent pipeline fullness, reducing errors in quantity determination and improving safety in bulk cargo operations.
