Electric trace systems are used to maintain or raise the temperature of pipes, tanks, Industrial equipment and processes. However, different environments have specific challenges that should be considered in the design phase to avoid premature failures and ensure efficient operation.
1. Moisture and exposure to water
Areas with high humidity or subject to direct exposure to water, as external industrial plants, sea or places with frequent washing, require liquid penetration resistant cables.
Humidity risks:
- Short circuit in the electric trace.
- Cable insulation degradation.
- Premature system failure.
Solutions:
- Use of cables with external moisture external coating.
- Proper protection of connections and terminals.
- Use of sealed derivation boxes to avoid infiltration.
2. Corrosive environments
Chemical industries, petrochemicals and food often operate in aggressive atmospheres, where chemicals are present that can deteriorate the electric trace cables over time.
Risks of corrosion:
- Degradation of the external coating of the cable.
- Exposure of internal conductors and system failure.
- Need for premature replacement of cables.
Solutions:
- Selection of cables with specific coatings for chemical resistance, as special fluoropolmers or thermoplastics.
- Additional protection for electrical connections with sealants and sealed boxes.
- Use of corrosion resistant supports and fixations to avoid mechanical degradation of the system.
3. Extreme temperatures
Industrial environments may face severe temperature variations, From extremely low temperatures (freezing environments) Even intense heat operations, as refineries and steel mills.
Extreme temperature risks:
- Cable Thermal Contraction or Expansion, compromising your integrity.
- Risk of overheating and premature degradation in places with high temperatures.
- Reduction of efficiency in very cold environments.
Solutions:
- Choice of cables with temperature range specification appropriate to the environment.
- Use of cables with thermal shielding to avoid deterioration.
- Proper thermal insulation of the pipe and the electric trace itself to minimize temperature fluctuations.
4. Areas with potentially dangerous atmospheres
Industries that operate in places with flammable gases, fuel dust or volatile vapors need to adopt strict measures to ensure that the electric trait is safe for operation in these environments.
Risks in potentially dangerous atmospheres:
- Risk of sparks and ignition due to electrical failures.
- Need for equipment certification to avoid electrical discharges.
Solutions:
- Use of specific electric stroke cables for these applications, with reinforced isolation and shielding, specific for classified areas ex.
- Implementation of Electric Overload Protection Systems.
- Continuous monitoring of system integrity, with regular inspections to avoid wear or failures.
5. Criteria for choosing the right cable
When projecting an electric trace system, It is essential to consider:
✔ Cable operating temperature range.
✔ Chemical and mechanical resistance of the coating.
✔ Ability to support adverse environmental conditions.
✔ Attention to electrical risks in areas with aggressive atmospheres.
✔ Integration with monitoring systems and thermal control.
On Scooter, Our experts evaluate each project individually to define the best electric trace solution, considering all environmental conditions and process requirements.
Conclusion
The choice of proper electric trace cable is essential to ensure safety, efficiency and durability of the system, mainly in challenging environments. Consider factors such as humidity, corrosion, extreme temperature and potentially dangerous atmospheres in the design phase avoids premature failures and optimizes system performance.
