Cast basalt bends

Description

These Cast Basalt Bends are manufactured using fine grade of raw material that is procured from your trusted vendors. Available in different sizes, we can also customize these bends as per the requirements of our clients. Linings made of Cast Basalt are proven to last six to ten times longer than steel, cast iron, Ni-hard, etc. These products are known for their sturdy constructions and dimensional accuracy.

According to customer requirements along with cast basalt production technology and we can offer various specifications and various shapes to meet client’s need.

Specifications

• Nominal Bore: 32 to 600 mm
• Wall Thickness: 20 to 30 mm
• Length: 500mm

Features

• 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 (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 approx. 90 kg/sq m; whereas bends and pipes are lined using Basalt Cylinders of various standard sizes from 50NB to 500NB.
• Temperature – Cast Basalt withstands temperature up to 450⁰ C
• 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.

Application Area

• Cement Industries
• Thermal Power Plant
• Paper Industries
• Fly ash Handling System

Why are cast basalt lined pipes so wear-resistant

The moulding process of cast basalt lined pipe includes solution casting, sintering and thermal direct sintering. So, why the cast basalt lined pipe is very wear-resistant cast basalt lined pipe has been widely used in building materials, chemical industry, metallurgy, mining and other industries. Cast basalt lined pipe is an ideal substitute material for steel, iron, lead, rubber, wood, etc. In some parts of many equipment. Individual metals cannot achieve high wear resistance, acid and alkali corrosion resistance, and have the advantages of extending equipment service life, reducing maintenance man-hours, improving production efficiency, and reducing product costs.

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.
