Diamond has many characters, such as high thermal, low permittivity, high band gap, super high hardness, low friction etc, which makes it possible to be widely used in industry.

Titanium nitride coating has great application in industry owing to its superior properties, such as good wear and corrosion resistance, low friction coefficient and good thermal barrier properties.

Insulation friction in the pipe thermal expansion, well counteract thermal expansion forces can effectively restrict the pipeline along the axial elongation, improved safety Buried heating pipe.
