Ceramic-lined pipes & elbows
Steel pipe lined with alumina tiles, built to your line drawing: straight spools, elbows, reducers and tees, flanged to your standard. For slurry, tailings, fly ash, bottom ash and other abrasive powders.

What we supply
| Item | Typical range* | Notes |
|---|---|---|
| Straight spools | About DN80–DN600 (3″–24″); lengths to your layout, e.g. 3 m and 4 m | Flanged or plain ends |
| Elbows and bends | Any angle; bend radius as specified, e.g. 1.5D or 3D | Heavier lining on the outer radius on request |
| Reducers and tees | To drawing | Branch connections lined to the same grade |
| Rubber-ceramic lined pipe | e.g. DN350 in long spools | For slurry with impact or pressure pulsation |
| Alumina tubes and sleeves | Bores from about 40 mm to 500 mm | Inserted into steel, or used as replaceable wear sleeves |
*Typical ranges from partner factories. Final sizes, lengths and tolerances are confirmed on the quotation.
Lining methods
- Bonded tiles — the usual choice for slurry and ambient-temperature powder lines.
- Welded tiles — for larger bores, or where the adhesive's temperature or chemical limits are a concern.
- Inserted alumina tubes — for smaller bores, where a one-piece lining avoids joints.
- Rubber-ceramic — where the line also sees impact or pressure pulsation.
The method is chosen by temperature, bore, pressure and particles — not by habit.



Hot ash lines
Fly ash can still be several hundred °C where it is collected. If that is above the adhesive’s rating, bonded tiles are the wrong choice; we specify mechanical retention or inserted tubes and confirm the method with the factory engineer before quoting.

Questions
Which parts of a line should be lined first?
Where wear concentrates: bends (especially the outer radius), tees, reducers and the spools just after pumps or feeders. Many plants line these first and leave straight runs until wear records show they need it.
Can you match our flanges and lengths?
Yes. Send the flange standard and rating — for example ASME B16.5 Class 150, EN 1092-1 PN16, JIS or AWWA — and the face-to-face lengths or an isometric drawing.
Ceramic-lined, rubber-lined or both?
Alumina resists sliding abrasion by hard, sharp particles and tolerates higher temperatures. Rubber cushions impact and suits many fine slurries at moderate temperature. Rubber-ceramic combines the two. Send the duty and we recommend one, with the reason.
Who is responsible for pressure design?
You or your designer specify pressure, wall thickness and flange rating; the factory builds the steel spool to that specification. We coordinate the documents but do not take on pressure design.
Send the line drawing and the medium.
Bends and spools are made to your layout. With the medium, temperature and flange standard we can recommend a lining and quote.
