Cast basalt lined elbows are used too many industrial areas where the abrasive, chemical and hot materials transported and which are commonly lined steel elbows. Cast basalt lined elbow is composed of steel pipe tee, cast basalt pipe and cement mortar concrete.
Cast basalt lined elbow is composed of steel pipe tee, cast basalt pipe and cement mortar concrete. 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.
Cast basalt pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, etc.
Cast basalt lined steel pipe is made with lined cast basalt pipes, coat steel pipe and the cement mortar filling between the two layers, it sets the wear resistance and corrosion resistance of cast stone pipe, the toughness of the steel pipe and the consolidation of the cement mortar in one. Greatly improve the product's ability of adapting various complicated working condition. At the same time using cement mortar as filling material, can make the pipe inner surface in alkaline medium, so that the surface of the steel pipe will produce a purified film to prevent corrosion. Cast basalt lined steel pipe is not only resistant to wear and corrosion, against high pressure, but also convenient and safe to transport.
The nominal diameter series of cast basalt lined steel elbow pipe is the same as the cast basalt lined steel straight pipe , the turning radius and central Angle can be made according to the requirements of customers.
The technical parameters of the coat steel of cast basalt lined steel pipe according to the operating pressure of the pipeline system to determine.

Other specifications of cast steel pipe lined with basalt can be manufactured according to customer technical requirements. Suitable for large-diameter basalt lining steel pipes with a nominal diameter greater than 800mm. Generally, according to the running status of the pipeline, different cement is used to fix the basalt brick inside the finished steel pipe to complete the basalt lining steel pipe. Its advantages are good wear resistance, wide range of use, basically not limited by the size of the pipeline and low cost of pipeline installation.
Comparison of Ceramic lines with few other materials under standard conditions :
| Material | Thickness(mm) | Approx life ( Months ) |
| Mild Steel | 10 | 3-5 |
| Cast Iron | 20 | 6-8 |
| Ni-Hard | 20 | 12-14 |
| Cast Basalt | 30 | 20-25 |
| Ceramic | 10 | 35-40 |
Hard & Compact Smooth & Inner Withstands High-Abrasion & Corrosion In any of the process industries especially Sled and Cement corrosion and abrasion lead to significant downtime of the plant. Further, the useful life or the equipment itself may get impaired because of the high abrasive nature of the materials being used. Thus, ‘wear mechanism’ results in hut down, replacement, etc., which is costly, resulting in loss to tilt: tunic of millions of dollars.
