Evidence-first editorial standard
This guide separates observed facts, engineering assumptions and data that still require confirmation. It does not promise a universal service life or replace the exact product data and project specification.
A quote is only as precise as the request behind it
Two suppliers asked for "a ceramic lining for this chute" with one photo will price two different linings, and neither price says what will actually be installed. The data below is what a supplier needs to propose a specific grade, thickness and fixing by zone. Gathering it takes a few hours on site and saves weeks of back-and-forth, as well as the surprise of extras after the order.
The equipment and its geometry: data 1 and 2
First, a drawing, or at least overall dimensions, plate thickness and the position of openings, stiffeners and inspection doors. Second, a wear map: where the current liner or steel is worn, how deep, and where it is untouched, with photos referenced to the drawing. The wear audit checklist shows how to record it. Without a wear map, the supplier must assume the worst zone everywhere, and the price rises accordingly.
What flows through it: data 3 to 6
Third, the material — type, maximum lump or particle size, moisture and whether it sticks. Fourth, the flow — tonnage or volumetric rate, its range, and for slurry the solids concentration and velocity. Fifth, the temperature at the steel, including peaks and cleaning. Sixth, the chemistry — pH, chlorides, solvents or anything that attacks steel or adhesive. These four decide the wear mechanism, and the mechanism decides the grade, as explained in abrasion, impact and erosion.
What has happened so far: data 7
Seventh, the history of the current protection: what it is, when it was installed, how long it lasted, and how it failed — worn through, cracked, debonded or knocked off. A liner that debonded points to fixing or substrate, not to grade; one that wore through evenly points to thickness or grade. The diagnosis method is in ceramic lining failure analysis. This single piece of data often changes the proposal more than all the others.
How it can be installed: data 8 and 9
Eighth, the fixing constraints — whether welding is allowed, whether the outside of the shell is accessible for bolting, the maximum weight a crew can handle, and whether the equipment vibrates. Ninth, the shutdown window and site conditions — how many hours, the temperature during installation, confined space, and who installs. A lining that cannot be fitted in the window is not a solution, however good the ceramic.
How to send it, and what comes back
Put the nine items on one page with the drawing and photos, and say which zones matter most. Induscoat reviews the request, asks for whatever is missing, and returns an offer by zone with grade, thickness, format, fixing and exclusions stated, so it can be compared line by line, as described in what a ceramic lining costs. Typical scopes cover IC TILE for chutes and hoppers, IC PIPE for pipelines and IC CUSTOM for shaped parts; the equipment pages start from our chute and hopper linings.
