Recommended sealing material for threaded sleeves:
-
Water / glycol heat exchangers, use Teflon tape.
In these cases, hemp cannot be used as sealing material!
Connection pipes without thread:
If the connection pipes are executed without threads, then a mechanical, force-fitting connection
(STRAUB coupling) is recommended (Figure 55). This coupling could be included optionally in the
scope of delivery from TRANE, if not, then it must be provided on site. In order to avoid a damage of
the copper pipe of the heat exchanger due to mechanical force, a ring is used to reinforce the cop-
per pipe (Figure 53 and Figure 54).
