Anti-Wear Curve Internally Basalted
Anti-wear curve internally basalted is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers. Anti-wear curve internally basalted combines the advantages of cast basalt and steel pipe, wear resistance, corrosion resistance, anti-high-pressure, transportation and easy installation.
This greatly improves the products adaptive capacity of 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.
Advantages
Good abrasion resistance
As the wear surface, the cast basalt ceramic is 8 Mohs hardness, whose wear resistance is 10 times that of hi-chrome cast iron alloy pipes. It can make little wear loss of the pipe during running, which extend the service life of the equipment largely.
Good thermal stability and excellent corrosion resistance
-50-350 ℃ is ideal temperature for the cast basalt ceramic lined pipe, and the inner wall of the pipe is cast basalt plates or tubes which have unique chemical properties of wonderful acid and alkali resistance.
Light Weight
The density is 3.63g/cm³, which is only half of the steel to reduce the load of equipment largely.
Easy and fast to fix on site
Welding, flange, flexible joint are available for fix with the equipment.
All the performance of Anti-wear cast stone lined steel pipe / cast basalt lining composite tube makes low project costs, the charges can be about 20-30% less than wear steel piping project.

Ceramic lined equipment and bends
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.
Characteristics
- High resistance to all types of chemicals.
- High resistant to sliding abrasion.
- Non weld ability & smooth surface results ill easy How of materials.
- Can With stand and temperature up to 200 C.
- Smooth Surface and resistant to abrasion & corrosion.
Technical details:
- Friction Resistance: As more material is passed over Cast Basalt, it gets polished up thereby reducing friction further. Cast Basalt improves in service after getting polished. Wetting also improves its performance in practical applications.
- Impact Resistance: Direct Impact Resistance at a perpendicular angle is low like all other ceramics, but it can be increased with proper installation by reducing the angle of impact. Cast Basalt can be used to mitigate sliding abrasion. Moreover, external impact strength of composite basalt pipe (enclosed in M.S. Shell) is always more than that of bare Ni-hard Pipe.
- Chemical Resistance: Cast Basalt is almost absolutely acid/alkali resistant (except Hydrofluoric Acid) and hence corrosion resistant.
- Weight and Sizes: Basalt Tiles are available in regular shape square of 200 x 200 x 30 mm thick, weighing approximately 90 kg/sq. m; whereas bends and pipes are lined using Basalt Cylinders of various standard sizes from 50NB up to 500NB.
- Temperature: Cast Basalt withstands temperature up to 450ºC.
- Life: Life of basalt-lined pipe is estimated to be 7 to 10 times that of Cast Iron, and 3 to 4 times that of Ni-hard Steel.
Why are cast basalt lined pipes so wear-resistant
Cast basalt pipe can be divided into straight pipe, elbow, three-way (four-way) pipe and variable diameter pipe, etc.
The cast basalt lined pipe has the characteristics of thoughtful structure, low water absorption, high compressive strength and good wear resistance. Except hot phosphoric acid, hydrofluoric acid and dissolved alkali above 30℃, it has good corrosion resistance to almost all inorganic acids, organic acids, alkalis, salts, water and organic solvents. The brittle material of cast stone has high hardness, and the problem of cast stone is that it is brittle and is not easily impacted by heavy objects.
Under the microscope, the cast stone can be seen interlaced with individual pyroxene spheres or feather-like crystallites of 0.05-0.1 mm. The thoughtfulness of this internal structure greatly improves the hardness of the cast stone, and its mohs hardness reaches 7~8. The greater the hardness of the material, the better the wear resistance. From the point of view of atomic and molecular structure, the combination of silicon and oxygen atoms of this silicate mineral is connected with each other by a strong force.
Individual cast basalt lined pipes have good wear resistance in blast furnace tank utilization, and meet application requirements in terms of wear resistance, but there are also brittleness of ceramic materials, which are easily broken during the process of falling ore. The construction of single-piece pasting is incomplete, and signs of aging will appear after a long time of pasting. The wear-resistant material not only has good wear resistance in the use of blast furnace tanks, but also meets the application requirements in terms of wear resistance, and has a mortar material, which is tough and will not be smashed in the process of falling ore. Good performance, combined with cement, not limited by time and so on. The wear resistance of cast basalt lined pipes is also the reason for their widespread use.
The connection of cast basalt line steel pipe
Cast blast lined pipe and fittings can connect with flange, quick assembly joints and welding.
Flange connection
Flange connection is one kind of common pipeline installation connections. By two pieces of flanges, pipeline, valve, equipments are connected and it forms a tight piping system. When pipeline pressure is larger, flange connection is priority selection. Flanges have lots of different sizes. Flange size is determined according to pipeline normal diameter and pipeline operation pressure.
The parameters of the outside steel pipe will be decided according to the working pressure of the system. The connection of the pipes and fitting will be of flange connections, easy—flexible joint connection or by welding.
