How do scale and oil coke quietly ruin your heating equipment? Learn prevention and maintenance to double the service life of your equipment.

In long-running heating systems, an outer “shell” often forms on the surface of electric heating tubes. This is the culprit behind declining equipment efficiency.

The “Thermal Barrier Effect” of Scale:
When heating hard water, calcium and magnesium ions precipitate and adhere to the tube wall. The thermal conductivity of scale is extremely low, only one-tenth to one-twentieth that of metal tubing. This not only reduces thermal efficiency (wasting electricity) but also causes internal heat to accumulate, eventually leading to tube wall rupture.

Carbonization of Thermal Oil:
In oil heating systems, if the oil temperature is too high or the flow rate is insufficient, the surface oil film undergoes thermal cracking, forming a varnish-like carbon deposit. This carbon layer not only hinders heat dissipation but also degrades the oil quality.

Modern Solutions:

Specialty Coating Technology (2026):
Our newly launched anti-scale coated heating tubes utilize superhydrophobic surface energy technology, making it difficult for scale to adhere.

Large R-Radius Bends:
A larger radius is adopted at tube bends to reduce fluid dead zones and lower the probability of scaling.
