Abstract: Ethylene Oxide (EO) is an important chemical raw material and traditional tank truck road transportation poses significant safety risks. Ethylene oxide piping transport offers substantial advantages in terms of safety, efficiency and stability. This paper first conducts a comprehensive comparison of three commonly used EO piping transport schemes from the perspectives of safety, one-time investment and operational convenience. For long-distance ethylene oxide piping transport, the loop piping transport scheme is prioritized. The paper then elaborates on the temperature control and safety measures for EO loop piping transport, addressing the engineering design challenges of long-distance EO piping transport based on ?the ethylene oxide properties.

Key words: ethylene oxide, long-distance pipeline, loop piping transport, temperature rise control, safety measures
