Cast Basalt Pipe Reducer
Adopt centrifugal casting manufacturing cast basalt pipe reducer. Molten lava in the vacuum state is poured into the high-speed rotation the centrifuge. In fixed standard time to exit the centrifuge into the annealing furnace. Cast basalt pipes have an excellent performance of high abrasive and high corrosion resistance. Often in the form of cast basalt pipe reducer appeared in various operating conditions the pump outlet location.
As hydraulic or pneumatic conveying worn or corrosive wear resistance, corrosion resistant lining material pipe can effectively protect the pipe prolong the service life of pipelines.
The whole production process of cast basalt wear resistant materials are completely finished under the monitoring of internal control procedures for the safe and orderly.

Cast basalt pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, etc.
Comparision Chart
Comparison of Ceramic lines with few other materials under standard conditions| Material | Thickness(mm) | Approx life ( Months ) |
|---|---|---|
| Mild Steel | 10 | |
| Cast Iron | 20 | |
| Ni-Hard | 20 | |
| Cast Basalt | 30 | 20-25 |
| Ceramic | 10 | 35-40 |
The excellent performance of cast basalt lined steel pipe is that it sets tenacity of steel pipe, abrasive resistance of cast basalt pipe, concreteness of cement mortar in one.
Chemical substance ( weight %) of cast basalt
| SiO2 | Al2O2 | Fe2O3 | TiO2 | CaO | MgO | K2O | Na2O | FeO | P2O5 |
|---|---|---|---|---|---|---|---|---|---|
| 43.13-41.12 | 12.5-13.52 | 8.64-9.5 | 2.02-2.62 | 9.05-10.22 | 8.65-10.47 | 1.4-1.75 | 4.62-5.28 | 4.82-6.25 | 1.1-1.38 |
This greatly improves the products adaptive capacity in complicated operation conditions. At the same time. Cement mortar is selected as the filling material and this can make the inside surface of steel pipe in alkali mediums. So the surface of steel pipe generates purifying films. These films can prevent being rusted.
