Analysis on the insulation of gasoline pipelines in refineries using electric heat tracing systems

In low-temperature environments, the light hydrocarbon components of gasoline pipelines are prone to volatilization, while the heavy components may precipitate wax, leading to reduced pipeline transportation efficiency and even potential safety hazards in oil refinery gasoline pipelines.Electric heat tracing systems, with their precise temperature control, explosion-proof and corrosion-resistant capabilities, and intelligent management capabilities, have been increasingly used for insulation of gasoline pipelines in refineries.

Why do gasoline pipelines in refineries require electric heating systems?

Prevent the volatilization of light hydrocarbons and component separation

The light hydrocarbons (such as butane and pentane) in gasoline are prone to volatilize at low temperatures, forming vapor locks that disrupt full-pipe flow, leading to metering inaccuracies or delivery interruptions. Electric heat tracing maintains pipeline temperature, suppresses gasification, and ensures stable single-phase flow of oil products.

Avoid the possibility of wax precipitation and viscosity increase in recombinant components

Some gasoline fractions, such as high aromatic hydrocarbon gasoline, may precipitate trace amounts of wax or increase viscosity at low temperatures, increasing pumping resistance and energy consumption.Electric heat tracing maintains oil fluidity through precise temperature control.

Anti static and leakage risks

Low temperature leads to a decrease in gasoline fluidity, and uneven flow velocity in pipelines may cause static electricity accumulation;Meanwhile, the cold shrinkage of metal pipelines can easily cause seal failure.Electric heat tracing constant temperature control can reduce temperature difference stress and suppress static electricity risk.

The electric tracing system, through technological innovation and intelligent management, has built a full process guarantee system for gasoline pipelines in refineries, from anti condensation, anti-static to stable transportation, becoming a suitable solution for temperature control in the refining industry.
