Removable Insulation Jacket

A sewn cover built from a measurement, not a nominal size

Removable flexible thermal insulation covers, also known as removable insulation jackets or flexible insulation blankets, use a multi-layer composite structure of an outer protective layer, a middle thermal insulation layer and an inner fitting liner. Each cover is fabricated through measurement, custom cutting and sewing against the actual configuration and operating conditions of the equipment and pipelines on site, so it adapts to irregular shapes and to multi-temperature-zone duty. It suits systems that have to be opened for maintenance, cleaning and servicing, is reusable, and provides energy savings as a supporting material in industrial thermal and cold insulation.

Temperature types

• Cold preservation type: low-temperature refrigeration and constant-temperature cold preservation.
• Low-temperature type: conventional warm conditions at 300 C and below.
• Medium-temperature type: industrial conditions from 300 C to 600 C.
• High-temperature type: thermal conditions from 600 C to 1000 C.

Core performance

• Good insulation across a wide range, from -70 C to 1000 C.
• Chemical stability with optional insect, mildew, aging and weather resistance.
• Class A and Class B1 flame retardant grades to national standard requirements.
• Waterproof and moisture proof against conventional water vapour exposure.
• Effective heat and cold retention, reducing energy loss and improving efficiency.
• Flexible and tough, conforming closely to irregular equipment and pipe curves.
• Easy to remove and refit, reducing interference with maintenance and cleaning.
• Reusable with a long service life and low overall cost.
• Customisable sizes and configurations for non-standard equipment.
• Smooth, wipeable surface that keeps the plant looking tidy.
• Blocks high surface temperatures and reduces the risk of contact burns.

Classification by function

• Internal temperature preservation: blocks external convection, reduces radiation and conductive exchange, stabilising process temperature.
• External thermal radiation protection: blocks strong external radiation and conduction to protect components and instruments.
• Anti-freeze: resists external low temperature and protects equipment, pipelines and instruments from freeze damage.
• Low-temperature cold preservation: blocks external heat transfer and maintains the internal low-temperature environment.

Applications

• Pipes, elbows, flanges, valves, tees and sight glasses.
• Reactors, heat exchangers, pump bodies, equipment heads and unit cabinets.
• Steam turbines, gas turbines, engine exhaust pipes and injection moulding machines.
• Instrument boxes and precision equipment in high-temperature areas.
• HVAC, refrigeration equipment and pipelines.

Usage precautions

• Install and remove along the preset opening direction; violent pulling and forced disassembly damage the sewn structure and surface layer.
• Avoid contact with sharp or hooked objects that puncture the fabric or detach the insulation layer.
• A flexible insulation auxiliary material for conventional dry static conditions; not resistant to strong acid or alkali, high-speed airflow erosion or continuous open flame.
• All technical data are for reference only; performance is affected by site conditions, installation and environment.
• Inspect fabric, stitching and insulation regularly and replace promptly when damaged, aged or detached.
