Pipes that move concrete, not budgets
Wear-resistant delivery pipes for concrete pumps and abrasive media. Hardfaced on the inside, flanged to your pump standard, painted signal red so nobody loses them on site.
Why a hardfaced pipe
Wear layer inside
The bore is protected by a chromium carbide layer. The abrasive slides on carbides, not on the pipe wall your pressure rating depends on.
No weak seams in the flow
Continuous overlay in the wear path. No longitudinal weld joints for concrete and slurry to attack first.
Bolt-in replacement
Flanged ends machined to your pump's standard. Swap a worn section in minutes, not a shift.
Standard pipe program
Straight pipes, bends and reducers for concrete pumping and abrasive media transport. The table shows the standard program. Custom lengths, angles and flange executions are quoted within 24 hours.

| Bends | 15° · 30° · 45° · 90° (custom radii and angles on request) |
| Interior hardness | up to 62 HRC |
| Flange standards | Machined to your pump system: Putzmeister ZX, Schwing MF, SK and compatible types |
| Finish | Signal red topcoat, ends protected for transport |
Typical program values. Exact dimensions, wall constructions and pressure ratings are confirmed at quotation, matched to your pump and placement.
Compatible with Putzmeister, Schwing, Sany, Zoomlion and CIFA systems.
Beyond concrete
The same hardfaced construction handles any abrasive flow: fly ash and bottom ash lines, slurry and tailings transport, dredging discharge, pneumatic conveying of cement and raw meal.
How long does a hardfaced pipe last?
Service life depends on the mix, pressures and placement rates. Hardfaced pipes typically outlast standard steel pipes several times over in the same line. Tell us your current change-out interval and we'll tell you what to expect.
Can you match my existing flanges?
Yes. Send the pump model or a drawing/photo of the current flange with basic dimensions. We machine ends to match so the pipe bolts straight in.
Do you supply complete sets?
Yes: straights, bends, reducers and clamps as a complete delivery-line package, or individual replacement sections in batch quantities.
Send your line layout or pump model
DN size, lengths, angles and flange type, or just the pump model and a photo. We come back with a firm offer within 24 hours.
