Selection Guide
Choosing the right ceramic lined pipe fitting depends on your specific operating conditions. Follow these guidelines for optimal performance and cost-efficiency:
- Wear type — Pure sliding abrasion → standard ceramic tile lining; Impact + abrasion → ZTA tiles or thickened ceramic in critical zones
- Particle hardness — Soft particles (coal, limestone) → 92% Al₂O₃ sufficient; Hard particles (quartz, corundum) → 95% or 99% Al₂O₃
- Temperature — Below 350°C → adhesive-bonded tile lining; Above 350°C → SHS sintered lining (no organic adhesive)
- Corrosive media — Acidic/alkaline slurry → 99% Al₂O₃ or SiC lining; HF or hot H₃PO₄ → avoid alumina, use SiC instead
- Pressure — Verify steel shell wall thickness meets pressure rating; all pressures ≤10 MPa supported
- Geometry — Elbows, tees, and reducers → tile lining with interlocking tiles for full coverage; Straight runs → SHS or centrifugal cast options
- Connection — Welding for permanent installations; Flanged for removable sections; Clamp for quick-change fittings

Silicon Carbide (SiC) Ceramic Products
WearTech silicon carbide ceramic products deliver unmatched performance where alumina ceramics reach their limits — in extreme temperatures (up to 1600°C), aggressive chemical environments, and ultra-high abrasion. With Mohs hardness 9+ and thermal conductivity 3–5× higher than alumina, SiC ceramics extend service life 5–7× longer than alumina in the most demanding applications. All products are custom-manufactured to your specifications.
Why Silicon Carbide?
SiC ceramics are fundamentally different from alumina. The strong covalent Si–C bond (88% covalent character) creates a material that retains full mechanical strength at temperatures where metals creep and alumina softens. Combined with exceptional thermal shock resistance, SiC is the material of choice when both extreme wear and extreme temperature are present.
- Extreme Hardness — Mohs 9+, Vickers 2200–2800 HV; 50% harder than tungsten carbide, 10× harder than stainless steel
- High Thermal Conductivity — 40–170 W/m·K (3–5× alumina), enables efficient heat dissipation and outstanding thermal shock resistance
- Low Thermal Expansion — CTE 4.0–5.0 × 10⁻⁶/K (half of alumina), minimizes thermal stress during rapid temperature cycling
- Superior Corrosion Resistance — Virtually inert to all acids, alkalis, and organic solvents except HF; annual corrosion rate below 0.01 mm in boiling 98% H₂SO₄
- High‑Temperature Strength Retention — Maintains 400+ MPa flexural strength at 1400°C; no creep below 1600°C
- Lightweight — Density 3.0–3.2 g/cm³ (1/3 of steel), reduces structural load and handling cost

How It Works
A hydrocyclone uses centrifugal force to separate particles by size and density --- no moving parts, no power required beyond the feed pump.
Tangential Feed
Slurry is pumped tangentially into the cylindrical upper section, creating a powerful vortex
Centrifugal Separation
Heavy/coarse particles are forced to the outer wall by centrifugal force; fine particles migrate inward
Underflow Discharge
Coarse particles spiral downward along the cone wall and exit through the bottom spigot
Overflow Collection
Fine particles rise through the center vortex and exit via the top overflow pipe (vortex finder)

Cyclone Lining Product Forms
⭐ Arc-Shaped Cyclone Tiles --- Customizable
The core customizable product for cyclone internal lining. Each cyclone section --- cylinder, cone, underflow spigot, vortex finder --- has a unique curvature and taper angle, requiring tiles precisely formed to match. We manufacture custom arc tiles from customer drawings, measurements, or samples, ensuring seamless fit and maximum lining coverage.
- Trapezoid-shaped taper tiles --- Interlocking edges for tight joints, easier installation into tapered sections
- Arc-shaped taper tiles --- Conform precisely to cyclone's internal radius, minimizing gaps and reducing turbulence-driven edge erosion
- Standard sizes: 50--150mm length × 20--100mm width × 6--50mm thickness
- Installation: Adhesive bonding or weldable studs
- Fully customizable --- Tiles manufactured to match your exact cyclone ID, cone angle, and section geometry
Cone Section Liner Sets
The cone section is the highest-wear zone in any hydrocyclone. We supply pre-formed cone tile sets with progressively changing curvature to maintain a smooth internal profile throughout the taper.
- Applicable cyclone diameter: DN100 -- DN1,500+
- Wall thickness range: 8 -- 50mm
- Inner diameter tolerance: ±0.1 -- 3.0mm
- Cone angle: custom per drawing
- Sections per cyclone set: 15 -- 25+ (depending on size)
- A complete cyclone lining set typically requires 20+ mold sets --- we maintain a library of hundreds of existing molds to minimize tooling costs
Modular Cyclone Liner Kits
Barrel section + cone section + adapter rings --- replace the most-worn cone independently without removing the entire lining.
- Step-interface design --- Controlled mating details ensure consistent positioning, reducing misalignment and edge erosion
- Quick-change underflow spigots --- Modular spigot inserts allow rapid replacement without full liner teardown
- SiC drop-in liner kits --- Precision-cast RBSiC assemblies (cone, barrel, vortex finder, spigot) replacing tiled constructions entirely
- Available up to 60″ (1,524mm) diameter
Ceramic-Rubber Composite Panels
For cyclones operating under high-impact slurry conditions.
- Alumina mosaic tiles vulcanized into wear-resistant rubber matrix
- 2-in-1 (ceramic + rubber) or 3-in-1 (ceramic + rubber + steel backing)
- Steel backing plate allows mechanical bolt-on installation
- Rubber layer absorbs impact energy and vibration, reducing ceramic fracture risk
- CN rubber backing enables cold-bonding installation without curing
- Standard plate sizes: 150×300, 300×300, 500×500, 600×600mm

Struggling with ceramic tiles debonding from equipment surfaces? Premature adhesive failure causing unplanned shutdowns and costly re-lining work? The right adhesive is the critical link between your wear protection ceramic and the substrate — get it wrong, and even the best ceramic fails.
WearTech offers two complementary adhesive systems engineered for industrial ceramic bonding across the full temperature spectrum. Our Epoxy-Based Adhesive (WT-EP100) is a two-component epoxy system that cures at ambient temperature, delivering shear strength of 18–20 MPa with excellent chemical resistance and good impact tolerance. It handles continuous service temperatures from -60°C to 150°C, with a high-temperature variant rated up to 180°C, making it the most versatile choice for bonding ceramic tiles to steel and concrete substrates in chutes, hoppers, pipes, and cyclone lining installations. Applied by trowel or spatula, it forms a permanent bond that withstands heavy vibration and aggressive slurry environments.
For extreme thermal conditions where standard organic adhesives cannot survive, our Inorganic Silicate Adhesive (WT-SI200) is a water-glass based inorganic binder system that withstands temperatures up to 1,000°C with zero organic degradation. It offers outstanding thermal shock resistance and achieves shear strength of 12–15 MPa — ideal for bonding ceramic components in kilns, furnaces, high-temperature ducting, and other installations exposed to direct flame or radiant heat. Applied by trowel, WT-SI200 cures through an air-drying and heat-activation process rather than organic cross-linking, ensuring long-term stability even under repeated thermal cycling. Together, these two systems provide complete coverage for every ceramic bonding challenge — from ambient-temperature wear protection to extreme heat installations.
