Product Details
Ascending Pipe Precast Refractory
Description
The lining of the upper structure of the rising tube is made of indeterminate cast refractory; the bottom structure is made of high-temperature glazed refractory. They have the advantages of excellent high-temperature performance, thermal shock stability, no tar bonding, no carbon buildup, strong carbon penetration resistance, good abrasion resistance, no carbon buildup, no tar sticking and long service life.
Features
High temperature resistance
Ascending pipe precast refractories are able to withstand extremely high temperatures, often thousands of degrees Celsius. They are ideally suited for use in high-temperature industrial environments in industries such as steel, cement and glass.
Thermal shock resistance
The structure and material composition of ascent pipe prefabricated refractories are able to withstand the stresses caused by thermal expansion and contraction, and are stable at high temperatures when experiencing sharp temperature changes.
Resistance to chemical attack
Ascending pipe precast refractories have excellent chemical stability and are resistant to corrosion from contact with fuels, exhaust gases or other chemicals.
Customization
Ascending pipe precast refractories can be customized to meet specific riser shape and size requirements. This means that prefabricated components can be produced in a variety of shapes to suit the layout and design of different piping systems.
Easy installation
As the Ascending pipe precast refractory is manufactured and adapted in the factory, it is much easier to install. Prefabricated components can be accurately installed in piping systems, making the construction process more efficient and reducing the need for on-site pouring.
Consistency and quality control
Riser prefabricated refractories are manufactured in a factory environment, allowing for better quality control. This ensures consistency and quality of each prefabricated component, providing reliable performance and durability.
Benefits and maintenance
The use of rising tube prefabricated refractories increases system efficiency and reliability, reducing downtime and maintenance costs. Their excellent refractory properties and chemical stability extend equipment life and reduce the frequency of repairs and replacements.
Application
This rising tube superstructure is mainly used in coke ovens.

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. |
