Heat tracing: electric pipe and tank heating

In plants, heating is installed for one of three reasons: something freezes, something loses its flow, or something has to stay at a set temperature. Which product you need is decided not by the equipment but by which of these three problems you have.

Frost protection or process temperature?

Pipe heating comes in two kinds. Frost protection keeps a fluid from freezing — the target is usually around +5 °C, power is low and the system runs seasonally. Process heating keeps a fluid at, or brings it to, a set temperature — viscosity, crystallisation and condensation belong here, power is higher and the system runs continuously. Cable selection starts with this distinction.

In both cases the cable is laid along the pipe and covered with insulation. On valves and flanges — points that are opened often and lose the most heat — a removable valve and flange heating jacket is used instead.

Self-regulating cable adjusts its own output to temperature: more heat at cold spots, less at warm ones, so overlapping runs do not overheat — preferred for complex geometry and long lines. Constant-wattage cable gives a fixed output per metre and is easy to calculate. Neither replaces the thermostat, residual current protection and correct earthing.

Heating jackets are made in our own workshops; heat tracing cables are sourced from selected manufacturers, with warranty and technical responsibility staying with us.

Why electric heat tracing

No steam line needed. Steam and hot-water tracing need a boiler, lines, condensate traps and a return. Electric tracing needs none of these; the cable goes on the equipment. If a working steam line already exists, steam is an option — building one for tracing is the most expensive route.

Heat only where it is needed. Electric tracing generates heat where it is used, with no transport losses, and a single valve or tank can be heated without running the whole plant.

Control at the thermostat. A digital thermostat and sensor hold the target; precise processes use PT100 sensors. The sensor sits between cable and wall and reads the surface, not the content — for exact product temperature add an immersion sensor, and keep the sensor away from the wind- and sun-exposed side.

Low maintenance, not zero. Before each season check insulation integrity, junction boxes, earthing and the sensor, and measure the cable's insulation resistance. Most faults come from damaged insulation and wet connections, not from the cable itself.

Insulation is part of the system

Cable without insulation does not work: most of the heat goes to the surroundings, the system runs constantly, never reaches its target and the bill is far above expectation. For keeping warm, installed power alone says little about cost — because the system runs under thermostat control, the real question is how many hours a day it is on, and insulation decides that.

Planning a line? Start with the pipe diameter, the fluid, the target and the lowest ambient temperature; we calculate W/m and metres with you.

Where it is used

  • Chemicals and petrochemicals — pipelines, reactors, storage tanks, refinery lines
  • Food — oil, sugar and glucose lines, honey and molasses storage
  • Pharma and cosmetics — raw material heating
  • Paint, varnish and adhesives — resin and glue viscosity
  • Energy — power plants, biogas, frost protection of equipment
  • Buildings — water lines and fire sprinkler lines

Frequently asked questions

What is heat tracing?
An electric heating cable system used on pipelines and industrial equipment for frost protection or to maintain process temperature. The cable is fixed to the surface, covered with insulation and controlled by a thermostat.
What is a self-regulating heating cable?
A cable whose conductive polymer core adjusts output to temperature: more heat where it is cold, less where it is warm. It protects itself on overlapping runs but does not replace the thermostat, RCD protection or proper earthing.
What is the advantage over steam tracing?
No boiler, condensate traps or return line; heat is generated where it is used; single pieces of equipment can be heated independently. If a working steam line already exists, steam is worth comparing — it is an infrastructure decision.
How is energy consumption calculated?
For heating up: from mass, specific heat and temperature rise. For keeping warm: from surface heat loss, where insulation decides. Installed power alone does not give cost — what matters is how many hours the thermostat keeps it on.
Can it be used in hazardous areas?
For Ex-classified areas we supply imported ATEX-certified cable; our own production is not ATEX certified. Please state the zone classification when requesting a quote.
Which certificates do you have?
Our products carry CE, GOST and EAC marking. Certificates are shared on product pages and with quotations.
