Wear resistant ceramic liner pipe

Wear resistant ceramic liner pipe is made through self-propagating high-temperature synthesis (SHS) technique.

The pipe consists of three layers:

  • ceramic lined pipe struct section
  • steel pipe
  • smooth ceramic lining (compact corundum)

It has many advantages over steel pipes, cast stone pipes, and steel-plastic compound pipes.

The combination of high rigidity of ceramic and high elasticity of steel gives the pipe unmatchable features as an abrasion resistant, heat resistant and corrosion resistant material for use in the fields of power generation, metallurgy, mining, and chemical industry etc.

Features and Advantages of ceramic lined pipe:

1). High Abrasion Resistant:
Vickers hardness of the corundum lining is HV1100 to1500, as high as that of tungsten-cobalt hard alloys, and the abrasion resistance is 20 times as carbon steel pipes. The composite ceramic lined steel elbow was used in a mining plant for about fifty thousands hours. The general service life of common steel elbow is about 700 hours.

2). Corrosion Resistant:
Corundum is a neutral material, and is acid-proof and fouling -free.

3). Heat Resistant:
Ceramic lined composite steel pipe can work under circumstances of -50 to 800 Celsius degree .

4). Lower Weight and Convenient Installation:
The ceramic lined steel pipes are lighter than alloy pipes, cast iron pipes, and cast stone pipes and can be welded or connected through flanges, which reduces the expense of transportation and makes the pipes easier to install. For the pipes with the same sizes, types and length, the weight of ceramic pipe is about 1/2 of the wearable cast alloy steel pipe’s, while the cost has reduced 10%~20% per meter. The weight of ceramic lined steel pipe is about 1/3 of the cast stone bent pipe’s, 1/2 of the cast stone straight pipe’s.
