How to check fit and access
Confirm panel handling weight, removal order, nozzle clearance and access to bolts and lifting points.
See inspection and acceptance checks →Equipment & process
Removable heat exchanger head insulation covers
Plan sections around nozzle positions and the head removal path.
Shell-and-tube exchanger heads opened for cleaning or tube bundle service.
Product views and construction details
Compare alternate views and see how the jacket opens, fits or fastens.
Design and specifications
Dividing the head into panels gives the maintenance team a manageable removal sequence without covering lifting or bolting points.
- Shape and construction
- Removable panels around the head and nozzle projections; identify each panel on the review drawing
- Facing, core and hot face
- Coated glass-fibre and fibrous core for suitable dry hot duty; review aerogel layers where the nozzle or head access is tight.
- Nominal core thickness
- 25 / 40 / 50 mm fibrous comparison; compare a thinner core at the same heat-loss target.
- Installation and closure
- Separate rated straps or lacing per panel; confirm accessible fastening and agreed panel weight.
- Dimensions to confirm
- Head diameter and profile, bolt ring, nozzle projection, lifting envelope and withdrawal path.
These are options for a custom quotation. Confirm the assembled materials, dimensions, service limits and finish in writing.
Review the construction detail
inspect lining, end collars and the space needed for bolt access.

Operating temperature and expected result
Assess large-area heat loss and hotspots around penetrations and the head-to-shell junction.
Agree the conditions, measurement points and target for the proposed cover before quoting. Record the complete assembly’s approved service limits separately from the target outside-face temperature.

Calculated outside-face temperature for Shannon LT450SS at 21.1 °C ambient, flat-surface model. The manufacturer lists a maximum service temperature of 232 °C for this model. The columns show its nominal insulation thicknesses in millimeters and the manufacturer’s approximate inch equivalents.
| Operating temperature | 25 mm (1 in) | 40 mm (1½ in) | 50 mm (2 in) |
|---|---|---|---|
| 121 °C | 37.9 °C | 33.3 °C | 30.8 °C |
| 177 °C | 47.3 °C | 40.3 °C | 36.3 °C |
| 232 °C | 57.2 °C | 47.8 °C | 42.3 °C |
These figures describe the cited manufacturer’s model. Shape, airflow, compression, gaps and closures affect the installed result. A lower outside-face temperature still needs to be checked against your site’s contact and inspection requirements.
