Insulating with Arma-Chek D >> Using Pre-Covered Tubes
ARMA-CHEK D PRE-COATED TUBES
Arma-Chek D pre-coated tubes are supplied with a self-
adhesive seal in 1 metre lengths. The covering fi nishes
approximately 10 mm before the end of the tube in order
to guarantee that the insulation material is installed “un-
der tension” around butt joints.
The Arma-Chek D pre-coated tube range is available for
pipes with an outer diameter of up to 89 mm. For larger-
sized pipes with an outer diameter of 102 mm up to 160
mm special (non self-adhesive) pre-coated tubes are
available on request.
Note:
Due to the semi-fl exible nature of the products
sleeving around bends is not possible!
INSULATING STRAIGHT PIPES (OD < 89 MM)
1. Clean the pipe surface with Armafl ex cleaner
removing any dust or other contamination.
2. Snap the tube onto the pipe.
3. Peel back both release paper strips step by step,
200 mm at a time. Align the seam joints and apply
heavy pressure to the complete seam, this action will
allow closure.
Note:
Always check the seam is fully bonded before
proceeding to the next steps.
4. Lay the covering tightly round the tube and fi x using
the factory applied adhesive strip.
5. Use correct Armafl ex adhesive to secure the longi-
tudinal seam. Apply on one side only. Always
remember to “stagger” longitudinal seams.
6. Secure the butt end on the under face of the Armafl ex
tube with the Armafl ex adhesive and also provide a
“wet seal“ to the adjoining tube.
7.
For internal application:
The butt joints have to be over secured with the
matching 50mm width self-adhesive Arma-Chek D
tape.
50 mm
For external application:
Over seal all seam and jointing details of the covering
with a “bead” of Arma-Chek Black or Grey Mastic.
Ensure all joints are staggered away from the direct
patch of rain, provide a watershed.
8. Use the Arma-Chek mastic to seal all seams and
joints! All seams and joints to have an allowance of a
min. of 10 mm wide and 3 mm thick mastic “beading”
applied.
USING THE ARMAFLEX TEMPLATE
The fabrication of bends and tees using Armafl ex tube
requires tubes to be cut to different angles. In order to
make this process quicker and easier, the Armafl ex tem-
plate is provided on every box of Armafl ex.
Additional copies are available on request (contact your
local Armacell representative for more information).
1. Place a copy of the Armafl ex template face up on a
table or worktop.
2. Line a tube of Armafl ex across the template parallel
along the horizontal base line.
3. Select the required angle cut from the template and
cut along this line.
