Electrically traced
Electrically traced tubing
Freeze protection. Temperature maintained.
An electric heater within the insulated bundle supplies heat for freeze protection or temperature maintenance.
Specify the required temperature, power supply, sensing and protection together. PMA can help review the appropriate construction.
The range, at a glance. The detail that matters.
Compare the construction, tube sizes, materials and heating limits before bringing your operating conditions together.

4
¼, ⅜, ½ and ¾ inch outside diameters are listed across the range. Availability depends on the family.
STAINLESS STEEL
316/316L
A common process-tube material. Copper and fluoropolymer options are also listed, depending on construction.
ELECTRIC HEATER LIMITS
85–204°C
Published operating limits span low-temperature self-regulating to power-limiting heaters. These are not guaranteed maintained temperatures.

Reliable lines.
Considered systems.
SpecificationElectrically traced tubingFreeze protection. Temperature maintained.
An electric heater within the insulated bundle supplies heat for freeze protection or temperature maintenance.
Steam traced tubingProcess heat. Carried along the line.
A steam tracer transfers heat to the process tube for temperature or viscosity maintenance.
Pre-insulated tubingInsulated transport. A considered construction.
Insulated tubing carries steam, gas or liquid without an integral electric heater.
THE COMPLETE BUNDLE
Where construction
meets duty.
The process tube, heating arrangement, insulation and jacket each have a role. Consider them together around the fluid, temperature and installation.
Electric tracing
Heat alongside the process tube for a defined freeze-protection or temperature-maintenance duty.
Steam tracing
A steam tracer transfers heat to the process tube. Review the supply and condensate return together.
Pre-insulation
Reduce heat loss during fluid transport. Review cold shutdowns separately when active heating is absent.
SPECIFICATION STARTS HERE
Define the line.
Bring the process, temperature duty and installation together. Four inputs help shape a complete tubing specification.
01 / PROCESS
Understand what flows.
- Fluid & duty
- Define the fluid, flow and pressure, together with the required line duty.
02 / THERMAL
Set the temperature duty.
- Temperature
- Specify the maintained temperature, inlet conditions and ambient extremes.
03 / CONSTRUCTION & INSTALLATION
Consider the complete line.
- Tubing & jacket
- Review tube count, dimensions, materials, insulation and the jacket environment.
- Utilities & route
- Confirm power or steam, controls, line length, supports and terminations.
