Electric Heat Tracing for Oil and Gas Facilities
Oil, Gas and Petrochemical Plants
Oil and gas facilities require robust heat tracing for freeze protection, process temperature maintenance and critical plant equipment. Pro Therm combines engineering, suitable hazardous-area systems and worldwide installation with its own heat tracing teams.

Tank connections, pipe racks, pump stations and loading systems have different thermal conditions. Heat tracing is engineered to match the specific process conditions and heat losses. Sound design starts with product, temperature, insulation, pipe and tank geometry, and ambient data for each area. Pumps, flanges and valves may add significant heat loss.

Long pipelines and system architecture

For long runs, circuit length, supply voltage, feed points, power distribution and maintenance access can strongly influence heating technology selection. Circuit distribution should account for maintenance boundaries and isolation. Feed points, junction boxes and sensors must remain accessible after insulation is installed.
For international projects, supply, country, area classification and project-specific evidence need early clarification. Responsibilities for supply, installation, electrical connections and insulation are equally important. Pro Therm coordinates the agreed scope with its own installation teams and the site's handover requirements.

Define critical transfer paths for restart

Restart requirements are established along the intended transfer path: tank outlet, pump, filter, main line and delivery point can cool at different rates. Product data on viscosity or solidification help describe the necessary minimum conditions.
Heat tracing is considered together with process interlocks. An adequate temperature on the main pipe does not prove that every connected item is ready for service. The operator defines which measurements and status indications are needed for an operating release.

Why is heat tracing used on oil and gas piping?
Typical reasons include freeze protection, pumpability, viscosity control and process temperature maintenance.
Which heat tracing technology is best for long pipelines?
It depends on length, power, voltage, temperature and project requirements; several technologies may be suitable depending on the application.
Can Pro Therm install heat tracing on international oil and gas projects?
Yes. Worldwide electric heat tracing installation is a core Pro Therm service.
Why include pumps and filters?
They can create additional heat losses and cold transitions. Their heating duty and maintenance accessibility are therefore assessed with the pipe route.

Tank farms and loading areas
Tank connections, pipe racks, pump stations and loading systems have different thermal conditions. Heat tracing is engineered to match the specific process conditions and heat losses. Sound design starts with product, temperature, insulation, pipe and tank geometry, and ambient data for each area. Pumps, flanges and valves may add significant heat loss.
Hazardous locations
Hazardous areas are common in oil and gas applications. Heating cables, accessories, controls, temperature limitation and installation must match the actual area classification and project specification.
Standards reference (checked 14 October 2026): IEC/IEEE 60079-30-1:2025 and IEC/IEEE 60079-30-2:2025 are international references for resistance trace heating in hazardous areas. Germany still lists DIN EN 60079-30-1:2018-04 and DIN EN 60079-30-2:2018-04 as current national editions. Equipment group, permitted EPL, protection concept and evidence for the actual assembly determine suitability.
