(54) | Corrosion-protected construction in a pipe heat exchanger and a method for forming the construction |
(57) The invention relates to a corrosion-protected construction in a pipe heat exchanger,
which construction includes a pipe (11) protected from corrosion by a surfacing (15)
and a pipe plate (13) forming the frame of the heat exchanger and supporting the end
of the pipe (11). In addition, a through-hole (14) is formed in the pipe plate (13)
for the pipe (11). The construction also includes an attachment piece (16), made of
corrosion-resistant material, arranged between the pipe (11) and the through-hole
(14). The attachment piece (16) is of a hardening corrosion-protection substance,
which essentially fills the entire space (17) between the pipe (11) and the through-hole
(14). The invention also relates to a method for forming the corrosion-protected construction
in a pipe heat exchanger. |
