Hoop Strength:
Hoop strength is the resistance against radial pressure. The strength
of the ceramic -lined steel composite pipe is 300 to 500MPa.
Compression-Shear Strength:
Compression-shear strength is the bonding strength at the interface
between the ceramic layer and the steel pipe. The compression-shear
strength of the ceramic-lined composite pipe is 15 to 20MPa.
Resistance to Mechanical Shock
The ceramic layer does not crack or flake off when the composite
pipe receives a mechanical shock.
Resistance to Thermal Shock
The ceramic layer does not crack or flake off when heated to 800℃
and then quenched.
Resistance to Abrasion:
The ceramic-lined steel composite pipe has exceptional resistance
to abrasion. Its service life in materials transportation with
hard abrasives is more than 20 times longer than in common steel
pipe.

Resistance to thermal shock |
A composite elbow was used
in a mining plant for about fifty thousands hours. The general
service life of common steel elbow is about 700 hours. |
Good Weld Ability
The ceramic-lined steel composite pipe can be joined by welding
the steel pipe layer.
Light Weight
The ceramic-lined steel composite pipes are lighter than alloy
pipes, cast iron pipes, and cast stone pipes, which reduces the
expense of transportation and makes the pipes easier to install.

|
Good weld ability |
The relative weight of the
composite pipe is about 40-50% lighter than that of the
cast stone pipe |
