One-piece ceramic liners for pipe, elbows and spools in abrasive and corrosive service.
A ceramic sleeve cast and fired in one piece, set into a steel pipe.
No tiles, no epoxy joints, no sprayed layer.
Ceramic lined pipe is steel pipe with a ceramic layer on the inside that takes the wear from abrasive or corrosive media. CeraLine makes that layer as one cast piece: a fired ceramic sleeve with a smooth bore and a constant wall, mortared or bonded into the steel body before it ships. With no tile joints and no epoxy for the media to wash out, the liner wears slowly and evenly across its surface instead of failing first at the seams.
Many inquiries start with the words "coating for my pipe". A coating is a layer sprayed or troweled onto the steel, and its life ends where the stream has cut through to the metal underneath.
A CeraLine liner is a part of its own. It is cast, fired and at least 1/4 inch thick, with walls up to 6 inches in elbows and 8 inches in spools where the wear calls for it.
Blasch does not coat or spray. If you came looking for a coating, the real question is how much wear wall your process needs, and a cast liner gives you that wall in solid ceramic.
Tiled, segmented and one-piece liners can use the same ceramic. The difference is how many pieces meet inside the bore.
In a lined pipe the ceramic is rarely the first thing to go, the joint between two pieces is, so the fewer joints in the bore, the longer the line runs between shutdowns.
CeraLine covers the straight runs, the bends where the stream changes direction, and the fittings that tie a lined line into the rest of the plant. All wear products
Long and short radius, 45, 90 and 180 degrees, built to the center-to-face dimension of the elbow it replaces.
Straight lined sections up to 7 ft long and 3 ft in diameter, with ends that match your existing flanges.
Reducers, choke rings, tees, wyes and laterals, where a change in diameter or direction speeds up the media.
Every part is designed for one line. The ranges below show what the casting process covers.
| Elbows | Pipe and spool liners | |
|---|---|---|
| Inside diameter | 1/2 in to several feet | up to 3 ft |
| Wall thickness | 1/4 in to 6 in | 1/4 in to 8 in |
| Geometry | long and short radius, 45°, 90°, 180°, custom angles | straight, up to 7 ft long |
| Ends | ANSI flanges, Victaulic, weld on, slip on, threaded, precast flanges | same as elbows |
| Joints between sections | not applicable | shiplap, tongue and groove |
The ceramic grades are alumina bonded silicon carbide (ALTRON), reaction bonded silicon carbide (InVinCer RB), recrystallized silicon carbide (InVinCer Rx), nitride bonded (NITRON), oxide bonded (OXYTRON), sintered silicon carbide (ULTRON) and dense alumina.
The grade follows the medium: particle hardness and velocity for abrasion, temperature swings for thermal shock, chemistry for corrosion. Silicon carbide grades
Three lines where steel parts failed on a schedule the plant did not choose, each result with the application it was measured in.
Bagasse boiler ash line, Guatemala
Steel 90 degree elbows in continuous pneumatic ash conveying at 60 to 70 °C lasted 3 to 4 months. The CeraLine elbow went in in March 2023 with a 20.7 mm liner in a 100 mm bore. After 30 months about 2 mm had worn away at the point of highest wear, and the bore was still round.
FCCU catalyst transfer line, Greece
Steel elbows at the regenerator failed within days, with catalyst at 690 °C and constant temperature swings. Elbows lined with reaction bonded silicon carbide have passed 12 months, and about 13 of them, in 90 and 45 degree versions, now run in the same line.
Lithium battery plant, US Midwest
Stainless pipe and elbows carrying highly corrosive material had to be replaced every few months. Elbows and spools with reaction bonded silicon carbide liners in 304 stainless bodies with custom flanges have now run for more than a year.
CeraLine runs where steel lasts months: fly ash and bottom ash conveying, pet coke and fuel transport, carbon and trona injection, FCC catalyst lines, slurry and tailings lines, foundry sand, cement and battery materials.
Two things bring most lines to a ceramic liner: the media cuts through steel, or the chemistry eats it. Many lines have both, and the grade is chosen so one liner handles the abrasion and the corrosion together.
Where the line has to keep its inside diameter, the steel body is made one size larger and joined to the existing pipe with a special flange or reducer, so the bore has no step at the connection.
A drawing helps when you have one. Most CeraLine projects start without.
Medium, temperature, velocity, and how often the current part fails. Dimensions are enough to start.
A Blasch engineer chooses the ceramic, the wall, the joints between sections and the end connections, then draws the part.
The liner is cast, fired and set into its steel body in Albany, New York.
The finished elbow or spool bolts or welds in where the old part was, with no ceramic work in the field.
No. It is a solid ceramic sleeve, fired before it goes into the steel and never thinner than 1/4 inch. Blasch does not apply coatings or spray layers.
That depends on the medium, the velocity and the grade. The useful number is the wear rate: once you know how much wall a liner loses per year, the replacement can go into a planned outage.
With the right grade, yes. Thermal shock resistance is weighed together with abrasion and chemistry when the engineer chooses between silicon carbide grades and alumina.
Yes. Each part is built to the face-to-face or center-to-face dimension and the flange pattern of the part it replaces, so it drops into the existing line.
No. Send the dimensions, the medium and the operating conditions. A Blasch engineer designs the liner and produces the drawings for you.
Tell us what runs through the line and where it fails. A Blasch engineer comes back with a liner design for that line.
