Ceramic Lined Carbon Steel Pipe for Abrasive Conveying — Field-Weldable, Long-Life Composite Pipe
Ceramic Lined Carbon Steel Pipe bonds an α-Al₂O₃ corundum ceramic inner sleeve to a carbon steel outer shell through SHS (Self-propagating High-temperature Synthesis) centrifugal casting, producing a composite pipe built for extreme abrasion, hot slurry, and corrosive media where ordinary steel fails within months. Tianjin Youcheng Technology carries approximately 200 tons of stock and holds a standard production lead time of 7–10 days, supplying heavy-industry projects across more than 14 export markets.
What Is This Product?
This pipe uses a two-layer composite structure. The outer layer is a carbon steel base pipe — available in Q235B, Q355B, or L245 grade — providing structural strength and on-site weldability. The inner layer is a dense α-Al₂O₃ corundum ceramic with a Vickers hardness of HV 1100–1500.
SHS centrifugal synthesis brings the ceramic and the steel together at their interface, and a metallurgical bond forms there. Adhesive alone is not what holds the lining on. The join happens at the material level. So under vibration or thermal stress, the lining is less likely to come apart than liners that are fixed on mechanically.
The outer steel surface can take paint or a coating to guard against corrosion. Pipe ends are left as bare steel. Field welding during installation can then happen without special tools.

Product Advantages
The α-Al₂O₃ lining delivers measurably higher wear resistance than unlined carbon steel, making ceramic lined carbon steel pipe the preferred choice in pneumatic conveying and slurry transport systems where standard pipe fails prematurely. Because the ceramic bonds at the metallurgical level during synthesis, lining adhesion is stronger than adhesive-based alternatives — an important factor in pipelines that operate under vibration or fluctuating temperatures.
The ceramic layer has a low friction coefficient. Because of that, flow resistance goes down. Less scale collects over time too. Pumps can use less energy over the whole life of the pipe. Heat is the other side of this. The pipe is rated to work at temperatures up to 900°C. That figure depends on the bonding method. Sintering systems and fly ash lines are where it fits. Other high-heat processes are a fit as well.
Putting it in on site is simple. The bare steel ends take a weld right there in the field, and any standard welding method will do. Elbows with the same ceramic lining come off the same production line. So do tees and reducers. One wear-resistant system then keeps the same lining material and the same thickness all the way through.
Application Scenarios
Power generation: fly ash and pulverized coal systems. Fly ash moves at high speed and eats through ordinary carbon steel pipe in almost no time. Power plants put ceramic lined pipe in a lot of places, on ash discharge lines and on pulverized coal conveying lines. Those pipes get changed out often. Every swap costs downtime, and downtime costs money.
Mining and mineral processing: tailings and slurry transport. Tailings slurry carries sharp mineral bits along with it, and the pressure behind them is high. Concentrate lines run wet, then dry, then wet again. The ceramic lining handles both the scraping and the wear that this cycle brings.
Steel and cement production: hot abrasive material handling. Hot, coarse raw material moves through sintering systems and cyclone separator outlets. Walls on unlined pipe like that get thin fast.
Metallurgy and coal industry. These pipes turn up anywhere abrasive powder or slurry gets pushed along under pressure. You will also find them in spots where stopping work to swap a pipe drives running costs up.
Quality Control Process
No pipe gets shipped until it clears a set inspection flow.
- Ceramic hardness verification: We run the HRA test to confirm the lining hits the wear resistance level we asked for.
- Bond integrity check: Does the bond hold? Ultrasonic testing (UT) and shear tests give the answer. They show if the ceramic will delaminate when vibration or thermal cycling hits it.
- Dimensional tolerance inspection: Wall thickness gets measured. Pipe-end alignment is checked the same way. Whatever the project specifications call for, both are held against that number.
- Surface integrity review: Micro-cracks can sit inside the ceramic layer. So can spalling. Visual inspection and dye penetrant testing are what find them.
- Hydrostatic pressure testing: We put the carbon steel shell under pressure. This test shows the shell can take it. It also shows there is no leak while the unit runs.
A Mill Test Certificate (MTC) ships with each order. That certificate uses the EN 10204-3.1 layout. Standard NDT is part of the order too. An outside agency can handle third-party inspection as well. You pay extra for it.
Ceramic Lined Carbon Steel Pipe Customization & Supply Options
We match your project requirements on pipe grade, outer diameter, wall thickness, length, and pipe-end type. Cut-to-length and beveling work can be done to order. We also take OEM and ODM orders. Those can meet different national standards. They can follow your own drawings too.
Orders ship in steel frames or wooden crates. Both suit international freight. Sea and land shipping reach Kuwait, Russia, Brazil, Belgium, Kenya, plus more than 10 other markets. Stock runs about 200 tons. Standard specs for Ceramic Lined Carbon Steel Pipe need 7–10 days to produce. That lines up with typical project schedules.
FAQ
Q: Can This product be cut or welded at the job site?
A: We do not advise cutting the ceramic lining at the site. That lining is hard, and it cracks easily. Diamond tools are needed to cut it. Before the pipes ship, they should be made to the lengths you need. The plain steel ends are a different case. Those can be welded on-site with normal welding methods.
Q: What does the pipe do about thermal expansion differences between the steel and the ceramic?
A: SHS manufacturing forms a metallurgical bond at the steel-ceramic interface. That bond is what soaks up the difference in thermal expansion when the pipe heats and cools. Runs hot, or cycles a lot? Talk to our technical team about your operating conditions before you order.
Q: Does the pipe hold up to mechanical impact?
A: External loads land on the carbon steel outer shell, and that shell gives the pipe its structure. Sharp or heavy impact is another story. Ceramic is brittle by nature. One hard blow in a single spot can chip or crack it, so do not let that kind of direct impact reach the lining.
Q: How do pipes get joined out in the field?
A: Pipes in the field are often joined with flange connections. Groove couplings are another way. Welding is used too. Those welding steps are set up to protect the ceramic layer inside. Matched ceramic-lined fittings can complete the system. Elbows, tees, and reducers are some of them.
Q: What customization choices can you pick?
A: Pick the pipe grade you need (Q235B, Q355B, L245). Outer diameter is 68–1220 mm. Wall thickness is 4.5–24 mm. You also set the fixed-cut length. Pipe ends come plain or beveled. Need an anti-corrosion coating outside? We can add one on request.
