Comparison between new type and traditional type
| NEW TYPE | TRADITIONAL TYPE |
| Smooth surface, less joints, less carbon and dust deposition | Traditional ascending pipe is installed by refractory bricks, after installation, the surface is rough and has many joints. It is easy to accumulate coal and dust. |
| Simple structure New type consists of three parts: glazed base, glazed bottom pipe, monolithic casting upper pipe. | Complicated structure |
| Easy to install the ascending pipe, using the bolts to link the three parts. | Complicated installation |
| Reduce the repair times and save the cost. | Frequent repair and high cost |
| Long working life | Short working life |
| Solve the gas leakage problems, reduce the environment pollution and heat dissipation, lead to energy saving. | Long time mechanical operation and chemical damage on the joints, leading the joints to become bigger. Gas leakage and environment pollution. |
Main Composition: Al2O3
Application: Coke oven, etc

Product Introduction
The lining of ascending pipe upper structure is made of monolithic casting refractory; bottom structure is made of high temperature glazed refractory. There is less carbon deposit on the surface of the pre-cast refractory. New type pre-cast plays a very good role in thermal insulation.
Features
1. Smooth surface.
2. Simple structure.
3. Long working life.
4. Energy saving.
Application
It’s mainly for coke oven.
