The cast basalt liners are inserted and embeded with a dense cement mortar inside the steel pipe,it can be used in higher working pressure and so on.

Performance Characteristics:
1. Good Wear Resistance
The lining of this pipe is corundum ceramics with Mohs hardness of over 9.0, which is equivalent to over HRC90. Therefore, it has high wear resistance to any conveyed medium of electricity, coal, metallurgy and mines
2. Low Running Resistance Loss
3. Low Engineering Cost
Ceramic-lined composite steel pipe can reduce the cost of supports and hangers due to its light weight. Its total engineering cost is equal to that of cast basalt pipe, and 20-30% lower than that of wear-resistant steel pipe.
4. Good Temperature Resistance Ceramic-lined composite steel pipes can bear normal operation of long-term in range of -50 ℃ -900 ℃, with linear expansion coefficient of 6-8 × 10-6 / ℃.
5. Convenient Installation and Construction
The product has such good comprehensive performances as are heat resistance and mechanical impact resistance etc., and can adopt welding, flange connection, quick connection, etc. Safe and convenient construction can reduce installation costs.
