SHS ceramic composite pipes feature a smooth inner surface and are non-corrosive, unlike seamless steel pipes which have a rough, helical ridge on the inner surface. After testing by relevant authorities on the inner surface roughness and water resistance characteristics, the smoothness of the inner surface is superior to any metal pipe, with a water resistance coefficient of 0.0193, slightly lower than that of seamless pipes. Consequently, these pipes have the advantage of low operating resistance, which can reduce operation costs.

Corrosion-resistant and scale-inhibiting

The steel ceramic coating, being (a-AL2O3), is neutral in nature. Consequently, it boasts resistance to both acidic and alkaline substances, as well as corrosion from seawater, and also features anti-scaling properties.

Thermal resistance

Due to its single stable crystalline structure, this corundum ceramic (a-AL2O3) ensures the composite pipe can operate normally for a long time within a temperature range of -50 to 700°C. The coefficient of linear thermal expansion is 6-8×10^-6/°C, approximately half that of steel pipes. The material exhibits excellent thermal stability.
