ENGLISH
To prevent oxidation during soldering process, fill the inside of the BPHE with nitrogen
.
Threaded connections
Mount the BPHE first; add the pipes using threaded connectors.
The supply pipes of the BPHE should be fixed to avoid stress or tension of the thread
connections.
In case the buyer orders a junction or flange connection separately from the BPHE, we do
not feel responsible for bad quality braze/sweat of given connectors or possible accidents.
6. Initial operation
Before putting the BPHE into operation, it has to be checked whether the specified
maximum operating parameters provided by the manufacturers label are not going to be
exceeded.
Check any fluid connections for potential leaks.
The pumps that supply the BPHE have to be equipped with shut-off valves. Pumps
capable of generating a higher working pressure than the BPHE is designed for must be fitted
with safety valves. The system has to be air-free to avoid interference with BPHEs function.
To avoid pressure surges, pumps have to be turned on while the valves are closed.
It is necessary to check whether the pulsations and impulses are not transmitted to the
BPHE. The correctness of the mounting of the pipelines has to be checked to avoid
unnecessary loads on the connectors.
To avoid hydrodynamic shocks and the traces of air in the system, the cut-off and air
escape valves have to be opened during launch. The valves on the supply and return lines
must be opened slowly as much as possible.
The air left in the system and BPHE reduces the operation efficiency, as well as increases
the risk for corrosion.
7. Operation
The exceeding of maximally permissible temperatures and pressures, provided on the
label of the BPHE, is not allowed during operation.
The operation of the BPHE under strong drops of temperature and jumps of pressure
might lead to the damaging of the BPHE and is not tolerated. In case strong drops of
temperature, jumps of pressure and the hydraulic shock have occurred, it is necessary to
stop the operation of the BPHE, inspect visually the unit and in case of necessity perform the
hydraulic pressure test.
During operation avoid temperature drops bigger than 100°C between the primary and
the secondary channels.
It is prohibited to use aggressive mediums that can lead to corrosion of the materials
of the BPHE.
