Piping
5.4.1 Protecting flange faces against corrosion
Protect uncoated flange faces with a suitable anti-corrosive before connecting the
piping.
Verify compatibility with the material of any O-ring fitted in the mating flange.
5.4.2 Connecting the piping
DANGER
Impermissible loads acting on the pump nozzles
Danger to life from leakage of hot, toxic, corrosive or flammable fluids!
▷
Do not use the pump as an anchorage point for the piping.
▷
Anchor the pipelines in close proximity to the pump and connect them without
transmitting any stresses or strains.
▷
Observe the permissible forces and moments at the pump nozzles.
▷
Take appropriate measures to compensate thermal expansion of the piping.
NOTE
It is recommended to install check and shut-off elements in the system, depending on the
type of plant and pump. However, such elements must not obstruct proper drainage or
hinder disassembly of the pump.
✓
The suction lift line/suction head line has been laid with a rising/downward slope
towards the pump.
✓
The nominal diameters of the pipelines are at least equal to the nominal
diameters of the pump nozzles.
✓
To prevent excessive pressure losses, adapters to larger diameters have a diffuser
angle of approx. 8°.
✓
The pipelines have been anchored in close proximity to the pump and connected
without transmitting any stresses or strains.
1. Thoroughly clean, flush and blow through all vessels, pipelines and connections
(especially of new installations).
2. Before installing the pump in the piping, remove the flange covers on the suction
and discharge nozzles of the pump.
CAUTION
Welding beads, scale and other impurities in the piping
Damage to the pump!
▷
Free the piping from any impurities.
▷
If necessary, install a filter.
▷
3. If required, install a filter in the piping (see drawing: Filter in the piping).
