2. Guideline for each installation process
Part 3 Design and installation
2.4 Insulation work
2.4.1 Insulation
1) Operational steps
2) Bending vertical side of insulation
3) 'L' Fitting connection part insulation
EPDM length should be more
longer than pipe length.
Do not extend EPDM by force.
1
Use the original uncut insulation
material.
1
All of the fitting connecting parts
should be insulated.
Bring face to face the each end of
EPDM on fitting connection part.
1
Make fitting cover to fit the EPDM
insulation fitting cover should be
overlapped with insulation min 1
inch (2.5cm).
2
Bond the both cutting sides of
fitting cover.
3
Only in specialcase is the vertical
cutting of the insulation allowed.
2
Bond both sides of the surface of
EPDM and press them together for
long lasting bonding.
3
Dry it until it becomes thick and
sticky.
4
Put the pipe in EPDM insulation
carefully so that the pipe will not
get damaged with EPDM.
2
Bond on both side of cut surfaces
of move sure to use the correct type
of bond for EPDM cut surface
attaching.
3
Dry it until it becomes thick, sticky
and does not get detached.
