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
 
Convenient Installation
The ceramic-lined steel composite pipes can be easily connected by welding, or with flanges and soft easy connectors.
 
Convenient installation 
The composite pipes have good corrosion-resistant. There is no evidence of corrosion filling the composite pipes with bitter for one year (left), but the common steel pipe under the same condition is corroded seriously (right).
