The system layout can be customized according to oil viscosity, flow rate, pipeline pressure, temperature requirement, hazardous-area classification, outdoor environment and available installation space.
Materials and Customization
Oilfield media may contain water, sediment, salt, corrosive components or high-viscosity crude oil. Material selection should consider oil composition, water content, sediment content, working temperature, pressure, corrosion level and maintenance requirements.
For common crude oil or produced liquid heating, carbon steel or SS304 can be used for many system structures. For corrosive oilfield media, humid environments or higher-temperature applications, SS316L, SS310S, Incoloy or selected corrosion-resistant materials can be considered.
Heating element watt density, flow path and safety margin should be reviewed carefully for heavy oil, high-viscosity crude oil and oil-water mixtures.
Customization options include:
