Installation Steps Of Fluoropolymer, Titanium And Stainless

1、The
pipelines should be installed with a pressure limiting valve ≤ 0.4mmPa.
In order to prevent clogging impurities inside the piping system and
scratches on the bundle, it is necessary to install an easy-to-maintain
filter before the heat exchanger, and install a steam trap at the
outlet.
2、When
it requires installing multiple groups of products, they can be
connected in parallel. Centralized steam supply should be considered for
the separate steam boxes; each branch is a separate steam supply
system. The exhausts can also be connected in parallel, but it is
forbidden to connect them to the metal outlet of the heat exchanger so
as to avoid clogging at the outlet of the heat exchanger and the
splitting of bundles.
3、In
order to prevent the workpieces and crushing plates from damaging the
bundles during the process, it is necessary to make appropriate
isolation devices for the products. Our factory can manufacture
protective devices for the users, or provide protection and production
patterns according to user requirements.
4、When
temperatures are below 0 ℃ in winters, please drain the condensed water
from the products during off-time, to prevent freezing, which can cause
rupture of tubes.
5、When
changing amps for tube shell heat exchangers, please follow the
installation instructions and technical protocols. During test runs
after the products are installed, please operate in line with the
following procedures:
♦Step
1: open the corrosive liquid circulating pump inside the fluoropolymer
heat exchanger tubes. The circulation pressure is ≤ 0.45mmPa when the product is used.
♦Step 2: open the tube shell external circulation heating (or cooling cycle) pumps, pressure ≤ 0.4mmPa.
♦When
the product is in use, the pressure inside the heat exchanger tube
bundle is always ≥ tube shell heating and cooling circulating water
pressure. Prevent the pressure inside the tube shell is greater than the
pressure inside bundle so as to avoid squeezing the bundle.
