Built to take the wear
so your pipeline never has to
Complete rubber-lined and ceramic-hybrid-lined steel pipe spool packages for abrasive, corrosive and slurry services—engineered, fabricated, lined & tested to international standards, delivered as ready-to-install units with fixed pricing for up to 24 months.
The real wear happens on the inside
Slurry, brine, acid, and abrasive media attack pipelines from within — gradually thinning the steel wall until leaks appear. By the time external signs are visible, the damage is often already expensive to repair.
A high-quality rubber lining acts as a sacrificial barrier, vulcanised directly to the steel, taking the punishment so your pipeline lasts longer and maintenance stays on your schedule — not the pipe's.
Two specialists - One accountable package
We combine engineering support, world-class steel fabrication with specialist rubber lining to deliver complete, tested spool packages under a single Duratan quote.
Steel Fabrication
- Pipe spools, fittings, and structural steel fabricated to your isometric drawings, P&IDs and line list
- We work with SET-listed Thai steel fabricators offering ASME-certified pressure boundary manufacturing and substantial pipe & spool production capacity.
- Fabrication to AWS, JIS, BS, Norsok, AS, and ASTM codes and standards
- Flange drilling to ANSI/ASME B16.5 (USA), EN 1092/DIN (Europe), or AS 4087 (Australia) — matched to your project's governing standard
- ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified
- Every fabricated spool is dimensionally inspected before surface preparation begins, ensuring the rubber lining is applied only after the steelwork has been verified against the approved drawings
Rubber Lining & Vulcanisation
- Interior lining vulcanised onto the fabricated steel spool — bore up to 1.4m diameter or spool length up to 15m per cycle, depending on which combination your spec needs (send us your dimensions and we'll confirm the exact envelope)
- Natural hard and soft rubber, Butyl, Chloroprene, EPDM, and NBR compounds selected for your media, temperature, and abrasion profile
- Full lining procedure: surface blasting, primer coat, adhesive coat, rubber sheet lining, autoclave vulcanisation or open steam curing, 100% inspection, then painting and shipping
- Lining thickness up to 25mm, checked by magnetic thickness gauge to ISO 2808 / ASTM D7091
- ISO 9001:2015 certified, with full raw rubber lot traceability
Ceramic-Rubber Hybrid Lining
- For extreme wear zones (cyclone underflow, tailings lines, high velocity slurry elbows and knuckles), ceramic tiles can be embedded into the rubber lining during the vulcanisation process to dramatically extend service life in high-velocity or high-abrasion sections
- Ceramic tile vulcanisation-bonded into the lining during the same autoclave cycle as the pipe lining itself — not a separately applied layer
- Available within the same bore and length envelope as standard rubber lining
- Can be applied along the full spool or targeted at the specific high-wear sections of a longer line, where straight rubber alone would wear out first
- Ceramic tile in high-alumina grades — 92% to 99% Al2O3 — with zirconia-toughened alumina (ZTA) available for impact-prone sections where fracture resistance matters as much as raw hardness
- Tile hardness from roughly 950 up to 1,200 HV depending on grade — harder than hardened steel — matched to the abrasion severity of your application. Silicon Carbide (SiC) available on request for extreme thermal or chemical service
No single rubber compound is best for every application. The correct compound is selected according to your process media, operating temperature, abrasion profile and chemical environment.
| Compound | Hardness | Best suited to |
|---|---|---|
| Natural Hard Rubber | 60–90 Type D | High-temperature acid resistance — electrolytic equipment, HCl and alcohol recovery, bromine production |
| Natural Soft Rubber | 35–70 Type A | Slurry abrasion resistance — mineral processing and mining pipelines, including large coarse-particle duty |
| Butyl | 45–65 Type A | The broadest chemical resistance of the range — H₂SO₄, HF, phosphoric acid, FGD systems |
| Chloroprene (CR) | 55–70 Type A | Seawater and desalination piping, water box condensers |
| EPDM | 55–80 Type A | Heated water supply and water treatment, ozone and weathering resistance |
| NBR | 60–80 Type A | Oil and hydrocarbon resistance — petrochemical and refining service |
What stands between the process media and steel
Hover any layer in the diagram for what it does and why it's there.
Every spool is tested on both sides of the process — the steel fabrication and the rubber lining — with results issued as part of the shipment's Certificate of Conformance.
Lining Thickness
Magnetic thickness gauge check across the full spool, confirming the lining meets spec before it ships.
Holiday (Spark) Test
DC holiday detector checks the full lined surface for pinholes that could let process media reach the steel.
Bond Strength (Peel Test)
Universal testing machine confirms the rubber-to-steel bond holds under load — a lining is only as good as its weakest bond.
Hydrostatic Pressure Test
The fabricated steel spool is pressure-tested to your project's governing code by the fabricator, before the rubber lining is applied.
Dimensional & Visual Inspection
Spool dimensions, flange drilling, and weld quality checked against your isometric before lining and again before shipping.
Code-Stamped Fabrication
Available for spool packages that require code-stamped pressure boundary components.
SGS pre-shipment inspection
Independent verification before your order leaves Thailand, on every order.
Full material traceability
Steel mill certificates and heat numbers, plus raw rubber lot traceability, compiled into the shipment's Certificate of Conformance.
Certificate of Origin
Issued by Duratan as exporter of record. This supports preferential duty treatment for imports into Australia (TAFTA), New Zealand, Japan, China, South Korea, and other Free Trade Agreement partner countries.
Fixed pricing, up to 24 months
Hedged against raw rubber, foreign exchange and freight volatility, so your budget doesn't move mid-contract.
Flange drilling to your standard
ANSI/ASME B16.5, EN 1092/DIN, or AS 4087, confirmed at order.
