Custom Ceramic Tile Lined Elbows for Pneumatic Conveying

Custom Ceramic Tile-Lined Elbows for Existing Pneumatic Conveying Lines

Replacing a worn elbow in an existing conveying system is not always as simple as ordering another 90° bend. The replacement must fit the available space, align with the adjoining pipes, and maintain the required internal passage.

ELACERA supplies custom ceramic tile-lined elbows for pneumatic conveying systems, manufactured according to approved drawings. Each elbow combines a fabricated steel shell with an internal alumina ceramic tile lining to protect surfaces exposed to abrasive powders and bulk materials.

Product Specifications

All dimensions and construction details are subject to technical confirmation.

When a Standard Elbow Will Not Fit

Replacement elbows are often installed between existing pipe sections with limited room for adjustment.

Even when the nominal diameter and bend angle are correct, differences in center-to-face dimensions, straight-end lengths, or flange orientation can prevent proper installation.

For a drawing-matched replacement, ELACERA reviews the required bend geometry, connection details, and overall installation dimensions.

Flange bolt-hole orientation is particularly important for fixed piping arrangements. It should be clearly shown on the drawing rather than assumed from the flange standard alone.

Ceramic Tile Protection at High-Wear Bends

In pneumatic conveying systems, abrasive particles change direction as they pass through an elbow. Repeated particle impact can cause concentrated wear, particularly along the outer arc.

The alumina ceramic tiles form a wear-resistant surface inside the supporting steel shell.

Because an elbow has a curved internal profile, tile dimensions and positioning must be selected to follow the bend geometry. Particular attention is given to tile joints, exposed edges, and lining continuity near the pipe ends.

The lining thickness and fixing method should be selected according to the conveyed material, operating temperature, impact conditions, and approved construction requirements.

This product uses individual ceramic tiles, not an integral ceramic sleeve or ring lining.

Finished Bore and Connection Details

The finished internal bore deserves attention when replacing an existing steel elbow with a ceramic-lined version.

Ceramic lining reduces the available internal passage unless the outer steel geometry is designed accordingly. An abrupt internal step at the connection may expose a local edge to repeated particle impact.

The required finished bore, lining termination, and connection dimensions should therefore be checked together.

Before manufacturing, the approved drawing should establish the bend angle, radius, flange arrangement, inlet and outlet lengths, and other critical dimensions.

Applications

Custom ceramic-lined elbows can be considered for abrasive pneumatic conveying applications such as:

• Fly ash conveying in power plants
• Pulverized coal transport in steel and power industries
• Cement and raw meal powder conveying
• Mineral powder and bulk material handling

The appropriate lining structure depends on the actual material and operating conditions.

Request a Custom Ceramic Lined Elbow Quotation

For replacement projects, please send ELACERA the existing elbow drawing or a dimensional sketch.

Useful information includes the pipe diameter, bend angle, centerline radius, end connections, ceramic thickness, required quantity, and conveyed material.

If the original drawing is unavailable, photographs of the worn elbow and its installation position can help with the initial technical review.
