Ceramic-lined pipes & elbows
Finished steel spools, elbows, reducers and tees lined with alumina, built to your line drawing and flanged to your standard. Alumina tubes and tiles are also supplied on their own for companies that line their own pipe. For slurry, tailings, fly ash, bottom ash and other abrasive powders.
Lined pipe sections or ceramic components?
A finished lined section combines the pipe body, ceramic lining and agreed end connections. Ceramic tubes or tiles supplied separately still need to be incorporated into the equipment. Tell us which supply scope you need, so that the enquiry is reviewed against the right drawing and inspection requirements.
| Supply scope | What you receive | Usually suits |
|---|---|---|
| Finished lined sections | Pipe body, ceramic lining and the agreed end connections, as one part | Replacing a section or bend that can be specified, then installing the assembled part |
| Ceramic components | Alumina tubes, sleeves or tiles only; they still have to be fitted into the pipe | Fabricators that line or assemble their own equipment |

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 | Fitted in steel, or supplied on their own for your own lining work |
*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.
What to send us
Send the information you have. A drawing, sketch or replacement-part reference is a useful starting point; missing details can be confirmed while we review the enquiry.
- Supply scopeFinished lined sections, or ceramic components only
- QuantityNumber of spools, elbows and fittings
- MediumSlurry: solids type, specific gravity, % solids, d50/d80 and largest particle. Dry: powder type and particle size
- TemperatureMaximum, normal, and how quickly it changes
- Velocity and pressureIncluding pressure surges, if any
- PipeSize and how it is stated (DN/NPS, OD or ID), wall thickness or schedule, steel grade
- End connectionsFlange standard and rating, or plain ends
- LayoutLengths; for elbows, the angle and centreline radius. An isometric or drawing if you have one
- HistoryCurrent pipe material, service life and where it fails
Before an order is confirmed, we agree the drawing revision, lining arrangement, dimensions to inspect, end connections and who supplies what. Inspection records and photos follow that agreed scope.
Confirm the handover between supply and installation
Before comparing quotations, record the responsible party and acceptance point for each step. This prevents a quotation for ceramic components being mistaken for a complete installed pipe section.
- Drawing and interfaces: agree the drawing revision, mating connections, orientation and dimensions to check. Identify who approves the fit with the existing line before manufacture.
- Steel body and lining: state who supplies the pipe body and who fits the ceramic. Where different parties perform these steps, agree who checks the assembled section and resolves a mismatch.
- Pre-shipment inspection: agree the inspection location, items to check and records required. Identify any witness or approval needed before packing; do not assume a photo replaces a specified acceptance check.
- Receiving and site work: name the party responsible for unloading, receiving checks, installation and site acceptance. Record exclusions and unresolved items before confirming the order.
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.
Who fits the ceramic lining and checks the finished section?
Confirm this in the supply scope before placing an order. For a finished lined section, identify the party making the steel body, the party fitting the lining and the location of the agreed pre-shipment checks. For ceramic components only, the buyer needs to arrange fitting and inspection of the assembled pipe. A component inspection does not establish acceptance of the finished assembly.
Does a lined-pipe quotation include installation on site?
Do not assume that supply of a lined section includes site installation. Identify the installer and agree responsibility for receiving checks, handling, joint assembly and any site acceptance or commissioning checks. Site work, pressure design and operating approval must be assigned to the appropriate project parties; they are not included merely because a product quotation or inspection photo is provided.
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.
