How to check fit and access
Release the overlap from the working side, remove and refit the band, then check the end collars for gaps.
See inspection and acceptance checks →Steam & hot water
Wraparound flange insulation blankets
Use an overlapping closure that can be reached from the available working side.
Repeated flange pairs on straight utility runs with access from one side.
Product views and construction details
Compare alternate views and see how the jacket opens, fits or fastens.
Design and specifications
A wrap suits a flange pair that can be reached from one side and has enough room to pull the jacket around.
- Shape and construction
- Flexible band with a longitudinal overlap and shaped pipe exits
- Facing, core and hot face
- Coated glass-fibre outer face and enclosed flexible fibrous core sized for wrapping around the joint.
- Nominal core thickness
- 25 mm nominal comparison; check 40 mm for bendability, fit and closure reach.
- Installation and closure
- Reinforced overlap with rated tabs or straps facing the working side.
- Dimensions to confirm
- Outside diameter, joint width, pipe and adjacent insulation OD, working-side access and closure reach.
These are options for a custom quotation. Confirm the assembled materials, dimensions, service limits and finish in writing.

Operating temperature and expected result
Review continuity at the overlap and pipe transitions; keep any required leak-monitoring points clear.
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.
