Wear Resistant Elbows

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.

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 .

Ceramic Lining Pipe and Elbow

Ceramic Lining Pipe and Elbow have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. Ceramics with very low friction factor at low impingement angles decreases the abrasion of materials maximally. Its low density makes it easy to carry and install. Furthermore, its diamond-like hardness, fine grain structure and superior mechanical strength are the unique features that make it a wide range of demanding applications, such as coal preparation, power generation, iron and steelmaking, cement, asphalt, dredging, mining and mineral processing, oil and gas drilling.

Metals have good ductility but poor resistance to abrasion - which means that abrasion prevention is required when metal pipes are used in high-temperature fluid catalyst service. On the other hand, ceramics possess great hardness and abrasion resistance, but they are brittle. Metal Ceramic double pipe is a hybrid pipe using metal as an outer pipe and a ceramic material for inner pipe segments, applied together to utilize the two materials' advantages. Hence excellent wear-resistance and good corrosion resistance of the ceramics and high strength and toughness of metal can be well combined to get a comprehensive advantage of wear-resistance, corrosion-resistance and anti-scaling. They are suitable for applications in heavy wear working conditions.

Ceramics are among the hardest materials available and provide ultimate wear resistance in piping. In high wear applications, ceramic lined pipes have been demonstrated to be cost-effective by increasing service life and reducing maintenance costs. Sunny Steel supply ceramic lined abrasion resistant steel pipes to your custom dimensions and budget. Our ceramic linings are the highest quality materials available to ensure that we provide the most cost-effective solutions for our clients.
