Abrasion Resistant Elbows

1. The Manufacturing Process of 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.
Alumina Ceramic Abrasion-resistant Product 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. Obvious performance of abrasion resistant elbows :
1. Heat-resistance, -50 - 800 Celsius degree
2. Easy Installation and Anti-Scaling
3. Alumina Ceramic Abrasion-resistant Product 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.
4.Application Fields of  Abrasion Resistant Elbows
Paper Making: For conveying pulp.
Metal Mines: For conveying tailings, concentrates and backfill minerals.
Coal Preparation Plants: For conveying dense media, mixture and coal slurry.
Shipping: For clearing shipping channels and sediment transportation.
Power Plants: For deashing, deslagging, coal dropping, powder transportation

Characteristics and applications of inert alumina ceramic balls

图片
   Inert alumina porcelain balls have the characteristics of high strength, high chemical stability and thermal stability. They can withstand high temperature, high pressure and corrosion from acids, alkalis, salts and various organic solvents. They are widely used in petroleum, chemical industry, fertilizers, natural gas and environmental protection industries. As a support and covering material for the catalyst in the reactor, it can buffer the impact of liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor.       Inert alumina ceramic balls are used in industries such as environmental protection and environmental protection as covering support materials and tower packing for catalysts in reactors. Inert alumina ceramic balls have the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acids, alkalis a

What ‘s the advantage of ZTA toughened wear resistant ceramics

图片
  ZTA toughed ceramic is a new material with excellent performance and wide application prospects. ZTA, also known as alumina-zirconia composite phase ceramic, is a composite material composed of two ceramic phases, alumina and zirconia. It is a multi-phase ceramic with excellent chemical stability, thermal stability and high strength. It inherits the high hardness of alumina ceramics and the high toughness of zirconia ceramics, and has excellent wear resistance, high temperature stability and toughness. 1. Anti-wear performance: ZTA toughed ceramics have excellent wear resistance. It has high hardness and can maintain good wear resistance under harsh conditions such as high speed and high pressure. This makes ZTA tough ceramics widely used in high-speed friction, motorcycle brake pads and other fields. 2. High temperature stability:   ZTA toughed ceramics have a high melting point and good high temperature stability. In high temperature environments, it can maintain its original stre
