Abrasion Resistant Linings

Abrasion Resistant Linings

Alumina is a cost effective and widely used material in the family of engineered ceramics. Abrasion Resistant Linings have been developed and optimized for maximum wear resistance and corrosion resistance. A high density, diamond like hardness, fine grain structured 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.

We provides its customers with the full range of abrasion resistant lined pipe work including straight pipe, bends and elbows, reducers, tees and y-pieces. We offers a comprehensive range of lining materials designed to combat erosion.

Basalt and alumina ceramic are the two generally accepted lining materials. Other linings which complement the basalt and ceramic include Eucor, AZS, silicon nitride bonded silicon carbide, and ceramic filled epoxy coatings.

Anti-corrosion service life.
Main performance indicators: The wear resistance of the ceramic work surface is more than 100 times that of manganese steel, 20 times that of high chromium cast iron, and several times to several dozen times higher than that of wear resistant rubber. Ceramic metal bonding strength up to 300kg/cm2 can be used up to 500°C.

The use of equipment made of wear-resistant ceramics, the service life can be increased by more than five times, and the performance-cost ratio can be increased by more than three times.

Why Ceramic Coating?
  • Ceramic coating is used by the OE’s extensively on 2007 & newer exhaust.
  • Ceramic coating is recommended for parts that are exposed to extreme heat.
  • Ceramic coating is used inside of chrome stacks to reduce the outside temperature of the pipe.
  • Ceramic coating will increase the longevity of the chrome stack.
  • Ceramic coating produces more usable power.
  • Ceramic coating protects parts from thermal fatigue.
Factors that affect composite quality:

① due to the outer surface of the outer tube irregular, resulting in the outer wall thickness is not uniform.
By the Ceramic tile lined pipe forming the basic constraints, to make the outer tube in the elastic deformation range, uneven outside the tube wall thickness, making the mass production, in the loading of explosives, the amount is limited. The dose is small, the impact of a large wave, the outer tube is prone to permanent deformation, or even unsafe, making the binding force but decreased; the amount of small, the impact of small, lined with less than a one-time full plastic deformation, resulting in double Metal composite pipe adhesion is usually about 0.5MPa. Due to the characteristics of the explosive forming process, the liner liner is shrunk inward in the axial direction. In order to ensure that the nozzle round, had to be second correction.
② due to the small binding force, so that the inner and outer tube ring joint surface gap, lining pipe in the pipe end welding, will repeatedly bear the process of media transmission, alternating pressure changes in the reverse, bending, resulting in the connection material fatigue, cracking , Resulting in decreased corrosion resistance – (Finged phenomenon).
③ due to the amount of loading explosives are limited, the liner does not reach the full plastic deformation. 
As the reaction force generated by the shock wave is small, the inner surface of the liner pressure is not fully reflected, the liner straight seam welding is still in the state of tensile stress. Resulting in the liner surface as a whole, especially the straight seam welding, the ability to resist thermal stress corrosion.
