Line Heaters

WellFlex Line Heater consists of three components: shell, firetube and coil. The process stream flows through the coil, which is immersed in the upper portion of the liquid media bath of the shell. The coil preheats the flow stream before reducing the pressure across a restricting choke followed by post-heating coils. Fuel gas is burned in the firetube and indirectly transfers heat to the media, then to the coil, and finally to the process stream. WellFlex standard pre-assembled line heater include coil, heater and fuel gas system and have rated capacities up to 4.0 MM BTU/hr. WellFlex can also customize a variety of coil arrangements and design pressures.

How It Works

WellFlex Line Heaters help you control temperature in your process stream as pressures are reduced to production system. Line Heater controls the effect of temperature drop when the well stream passes through the pressure-reducing choke. They can also be used to heat gas transmission lines, flow line, separator inlets, flow line paraffin control, crude oil and process temperature control.
