Refractory anchor
Metal or ceramic support fixed to the shell that holds a monolithic lining in place.
In short
Metal or ceramic support fixed to the shell that holds a monolithic lining in place. JJ Projects sources it to the specification the buyer names. Typical reference, form: V-type and other metallic anchors; ceramic anchors.
Specification references
Typical references only. The governing specification is the one on your purchase order or datasheet.
| Property | Typical reference |
|---|---|
| Form | V-type and other metallic anchors; ceramic anchors |
| Materials | Alloy selected for the lining temperature |
| Installation | API 936 for installation quality control |
Specification references describe what the order names, not a certification held by JJ Projects.
Refractory
Typical uses
- 01Holding castable and gunned linings to steel shells
- 02Fired heaters, boilers, reformers and furnaces
- 03Ducts, stacks, cyclones and reactor vessels with monolithic lining
- 04Repairs where anchors have burned out or loosened
What to include in a request
A request with these details can be quoted without a round of questions. Send what you have and we will ask for the rest.
- 01Anchor type and shape, for example V-type, Y-type or other metallic style, or ceramic anchor
- 02Alloy, chosen for the temperature at the anchor, which is lower than the hot face temperature
- 03Anchor dimensions, and the lining thickness it must hold
- 04Spacing and layout pattern from the lining design, with the number of anchors
- 05Method of attachment, for example welded to the shell
- 06Quantity, and installation quality control, for example API 936
- 07Documents: material test report for the alloy where required

Questions
Questions
01How are anchors selected?
By the lining thickness and type, the temperature, the orientation of the surface and the vibration or thermal movement. These come from the lining design or the refractory supplier. Send the lining drawing or specification.
02What is API 936?
API 936 is the API recommended practice for quality control of the installation of monolithic refractory linings, including inspection and testing during application. It is referenced in the project specification, not a rating of the anchor itself.
Send the specification. We will take it from there.
