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.
- 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 90 degree is low like all other
ceramics, but it can be increased with proper installation by
reducing the angle of impact. Cast Basalt is the best wherever
sliding abrasion exists. Moreover, external impact strength of
composite basalt pipe 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 approx. 90 kg/sq m; whereas bends and pipes
are lined using Basalt Cylinders of various standard sizes from
50NB upto 500NB.
- Temperature: Cast Basalt withstands temperature up to 4500oC
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.

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.
