Fly-ash abrasion and high temperatures in coal and biomass boilers, ash handling and flue-gas systems.
Fly ash and pulverized fuel can erode elbows, fan casings, dampers and branch connections because fine particles follow high-velocity, turbulent gas paths. Bottom-ash or dense-phase systems introduce different particle sizes and impact conditions. The survey should therefore distinguish pneumatic erosion, sliding ash, impact and any corrosion caused by condensation or cleaning water before a ceramic lining is selected.
Operating and upset temperatures, thermal cycles, gas chemistry, dew point, ash composition, velocity, pressure, component expansion and access for inspection all affect the design. The steel shell remains responsible for pressure and structural loads. Adhesive or mechanical retention must be qualified for the exact exposure, and any expected wear-life statement should be based on a comparable ash system rather than a generic multiplier.
Distinguish the loads acting on each part of the process before comparing lining constructions.
Entrained particles can focus wear at elbows, branches, reducers, fan housings and internal steps. Velocity, solids loading and flow disturbance need to be considered together.
Suspended solids load pipes, elbows and transitions according to concentration, particle range, velocity and local turbulence. Wear can differ markedly between straight pipe and changes of direction.
Feed drops create local impact before material establishes a sliding path. Blockage, start-up and variable fuel or ash condition can change the controlling mechanism.
A useful enquiry replaces general labels with the service data that controls wear, installation and inspection.
Dry or wet duty, material identity, particle distribution, moisture and solids concentration.
Normal, minimum, maximum and upset flow; velocity where known and start-stop frequency.
Operating and design pressure for piping, plus normal and peak temperature at the lining.
Elbow radius, branch and reducer geometry, support locations and any internal bore steps.
Process chemistry, condensation, flushing, cleaning and outage condition.
Failure location, current material, wall-thickness-loss map or lining-condition map, inspection access and consequence of leakage or detachment.
Use these checkpoints to shortlist a construction without extending any product beyond documented operating limits.
Distinguish dry pneumatic erosion, wet slurry abrasion and gravity-fed impact before selecting a lining construction.
A pipe solution cannot be transferred to a bunker or chute without a new support and impact review.
Design the steel pipe or vessel for pressure, loads, supports and code requirements; then integrate the wear lining and transitions.
The ceramic lining is not the pressure boundary and does not replace piping-code assessment.
Confirm exact ceramic, bond, joint, shell and repair procedure against temperature, chemistry, moisture and cleaning exposure.
No generic material label establishes universal chemical or thermal resistance.
Create a repeatable baseline so future shutdown teams can distinguish deterioration from a different viewing condition.
Use line isometrics or equipment drawings to identify elbows, branches, first impacts and inaccessible zones before inspection.
Separate lining condition from pressure-shell condition and escalate any sign affecting containment under the plant integrity process.
Check outer elbow radii, bore transitions, joints, terminations, loose pieces and corrosion staining.
Establish dated baseline images and any available wall or wear measurements at the same reference locations.
Focus the wear survey on the components where material flow, impact and operating constraints meet.
Explore the available ranges associated with this sector, then confirm material, geometry and retention from the actual service conditions.
Final selection requires a review of the equipment, material handled, wear mechanism and operating constraints.
Move from a broad sector view to equipment- and wear-mechanism guidance before selecting a product range.

Yes. The steel assembly remains the pressure-containing and structural component. The wear lining must be integrated without replacing the applicable piping design, fabrication and inspection requirements.
Direction change, turbulence and particle impingement can concentrate wear at the outer radius, entry or downstream transition. Geometry and flow data are therefore as important as the material name.
Compare the same elbows, joints, transitions and impact zones against the handover baseline. Record loose pieces, joint recession, local wear, corrosion staining and any changed operating condition.
Share the equipment, material handled and observed wear so the enquiry can be reviewed against the relevant ceramic range.
