END CAPS AND TERMINATION POINTS
Using self adhesive Arma-Chek D tape / bandage:
Self adhesive tape or bandage can be used to cover the
open cell structure of the Armafl ex on oversize insulation
covers. The “feathering” technique can be used (see pic-
ture). The length of the feathering should be two times
insulation covers thickness. The edges of the “feather-
ing” should be reinforced using additional self adhesive
tape or bandage material on both ends. (Note: bandage
must be glued with the correct type of adhesive!)
Using covering:
Method 1:
1. Measure the following diameters of the end cap:
a) small (insulated) pipe diameter and
b) the large bore insulated body.
2. Using Arma-Chek covering as a template, mark out
2 half-semi circles which have the following measure-
ments:
a) small bore insulated pipe outer diameter
b) large bore insulated diameter of insulated body.
Allowance should be made to both the inner side of
the small diameter and the outer side of the large
diameter for feathering overlap length minimum equal
to the insulation thickness of the non covered area!
Method 2:
1. Measure the following diameters of the end cap:
a) smaller (insulated) outer diameter of insulated
body and
b) the large outer diameter of insulated body.
2. Using Arma-Chek covering as a template, mark out 2
circles with the same center and the following
measurements
a) outer diameter of small insulated body.
b) large bore diameter of insulated body.
Allowance should be made to both the inner side of
the small diameter and the outer side of the large
diameter for feathering overlap of minimum equal to
insulation thickness of the non covered area.
3. Cut out and modify the covering, fabrication using the
”feathering“ technique. When installing use the
correct type of Armafl ex adhesive!
4. For the quadrant overlap use Arma-Chek D self-
adhesive tape (in the correct size for the overlap) on
indoor applications, on outdoor applications the
covering material (rolls), which can be cut into an
approximate trapezium shape for the best fi t.
