Abrasion Resistant Bends
1.Ceramic-line d Abrasion Resistant Bends are produced by self-propagating high-temperature synthesis (SHS) and centrifugal casting technology. The effects of additives such as SiO2, CrO3, Na2B4O7 and ZrO2 on the densification degree, combining strength and the toughness of the ceramic layer were of prime interest. The results show that the densification degree of the ceramic layer can be improved by adding SiO2 and CrO3 in the thermite. This improvement correlated with the reduction of porosity of ceramic layer. The combining strength is increased through the addition of a suitable amount of Na2B4O7. The highest fracture toughness of ceramic layer is obtained at 7 wt.% of ZrO2 in thermite. Ceramic-lined compound steel pipe shows excellent service properties when it is used in tubular billet crystallizer, including the prevention of cracks and flakes.

Wear Resistant Elbows

1. The Manufacturing Process of Wear Resistant Ceramic Lined Steel Pipe and Elbows:
SHS-ceramic steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline which are produced in a way of Self-propagating High-temperature Synthetic process.

Wear resistant elbows are composed of three layers: ceramic, intermediate, and steel layers. The ceramic layer is formed by molten alumina at a temperature above 2500 degree.

The molten alumina produced from the reaction Fe2O3+2Al=2Fe+Al2O3 spreads on the inside wall of the steel pipe under the influence of a centrifugal force, then solidifies, so the ceramic layer has high density and smooth surface and bonds to the elbow.

2.Features of Alumina Ceramic
Alumina is a cost effective and widely used material in the family of engineered ceramics. Alumina ceramics have been developed and optimized for maximum wear resistance and corrosion resistance. A high density, diamond like hardness,fine grain structure and superior mechanical strength are the unique properties that make it the material of choice for a wide range of demanding applications.Ceramic has uses similar to Cast Basalt but it has greater resistance to wear in high velocity applications and impact resistance in extreme dynamic systems .

3.Product: Wear Resistant Elbows/Bends
Size: DN40-DN600
Wall Thickness: 3-10mm
Housing Material: Seamless Carbon Steel
Inner Material: 95% Alumina Ceramic
Ceramic Thickness: 3 to 6 mm
Normal Operation Velocity: 20-35m/s
Normal Operation Temperature: -50---800degree

4..Obvious performance of wear resistant elbows :
1. Heat-resistance, -50 - 800 Celsius degree
2. Easy Installation and Anti-Scaling
3. Abrasion-Resistance and hardness, is above 9.0
4. Corrosion-Resistance,10 times of stainless steel pipe
5. Economical Cost, 20-30% lower than that of anti-abrasion alloy steel elbows.

5.Application Fields
Paper Making: For conveying pulp.
Shipping: For clearing shipping channels and sediment transportation.
Metal Mines: For conveying tailings, concentrates and backfill minerals.
Coal Preparation Plants: For conveying dense media, mixture and coal slurry.
Power Plants: For deashing, deslagging, coal dropping, powder transportation
