Zirconia Ceramic Sleeves & Liners

 

Refractron Technologies Corp. is a leading manufacturer of technical ceramics. Products include both controlled porosity and densely structured ceramics designed to meet requirements specified by our customers for durability, chemical, corrosion and wear resistance, toughness, and density.

Refractron Technologies Corp’s Magnesia-partially Stabilized Zirconia (MgPSZ) is optimum choice in ceramic liners and sleeves where the traditional metal alloys fail. Sleeves and liners made with Refractron’s Mg-PSZ Zirconia have superior abrasive resistance as compare to carbon steel, 316Ss, D2-Steel, Stellite Alloys 6, and Tungsten Carbide. In addition, zirconia is inert to virtually all acids, bases, solvents, and other corrosive slurries and fluids.

Refractron’s MgPSZ zirconia ceramic liners will allow you to extend service life enabling you to improve operating efficiencies, reduce maintenance costs, and minimize downtime with less frequent repairs. Our zirconia is extremely strong, has superior toughness, and excellent abrasion resistant. Additionally we use a proprietary manufacturing process, starting with the highest purity raw materials that results in a chemically superior zirconia product as compared to the competition. This translates into superior chemical stability of the ceramic components in operation when subject to the corrosive liquids and slurries.

 

 

The range of dense structural ceramics using proprietary zirconia ceramics includes custom blended ceramic alloy powders formed by isopressing or extrusion to meet customer specifications. These ceramic alloy components are used in extreme wear and corrosion applications in the chemical and petrochemical industry as well as components for healthcare and dental applications.

Custom built liner and sleeve sizes include: 2” OD up to 13” OD by up to 20” Long and they are produced to order in as fired blanks or as finish components with a variety of tolerances and finishes. Mg-PSZ liners provide better (6X) Abrasion Resistance than Tungsten Carbide along with better (3X) Impact Resistance that Silicon Carbide.

Proven applications for structural zirconia ceramic includes: Chemicals [hot caustic, acids, solvents], Materials handling [abrasive fluids, suspensions], High velocity fluids, Oil and gas (pipe spools, liners, sleeves), Pulp and paper, Metal forming and All wear-prone and corrosive environments.

The range of dense structural ceramics using proprietary zirconia ceramics includes custom blended ceramic alloy powders formed by isopressing or extrusion to meet customer specifications. Refractron’s zirconia is offered in two materials Magnesia Partially Stabilized Zirconia, Mg-PSZ and Yttria Tetragonal Zirconia Polycrystal, Y-TZP. Refractron’s structural ceramic zirconia materials provide excellent erosion, corrosion and abrasion resistance along with temperature resistance, fracture toughness and strength. These ceramic alloy components are used in extreme service applications that take advantage of their superior wear and corrosion resistance. Numerous applications for these materials are in the chemical and petrochemical industry providing economic payback in the way of reduced maintenance and down time.

Zirconia is also becoming the material of choice for components in healthcare and dental applications. This dense structural ceramic material is usually precision ground using conventional diamond cutters and wheels. Machines used for precision grinding include: surface grinders, CNC milling machines, jig grinders, center less grinders, CNC lathes, ID grinders, etc.

In addition to liners and sleeves, the types of dense, structural ceramic components produced by Refractron include: valve components, plugs, pistons, precision ceramic balls, press tooling, dental blanks, extrusion tooling and wear plates. Other specialty products include a range of porous ceramic filters, diffusers and adsorbent filter/drier cores for refrigeration applications, dispersion parts, vacuum chucks, inkpads and gas probes.

We work closely with our customers to define their needs and the requirements of each specific structural ceramic application. Our engineering and sales team is great at attacking technical design and process problems, then customizing an innovative solution using our broad range of advanced industrial ceramics.
