Description

 

Polished 2mm 3mm 4mm Advanced 95%/99% Alumina Ceramic Sleeve

 

Alumina Ceramic Sleeve has the properties of self-lubricity and inadhesion, the roughness is only 1/6 that of steel pipes thus less flow resistance.

 

Surface roughness:

The surface processing can achieve very high precision: the inner hole surface can reach 0.005mm, the outer hole surface can reach 0.001mm, and the mirror polishing can reach Ra0.1.

  1. The maximum height is 600mm
  2. The maximum length is 2500 mm
  3. The maximum CNC length is 1200 mm

 

 

 

 

 

The advantages of alumina ceramic sleeve:

1.Corrosion resistance

Advanced ceramic sleeve with extremely stable molecular structure and no electrochemical corrosion, thus they can resist erosion of acid, alkali, salt solutions and organic solvents.

 

2.Thermonstability

Working temperature can be as high as 1400 degree celsius.

3.Good self-lubricity
