Pressure classes and their applications
PN (Pressure Nominal) is the nominal pressure rating of a pipe measured in bar. Below are typical applications of PN6 through PN25 polyethylene pipes for potable water and gas.
PN66 bar
- ▸Low-pressure systems
- ▸Sewer and drainage
- ▸Irrigation
- ▸Gravity (non-pressure) flow
PN1010 bar
- ▸Potable water
- ▸Medium-pressure irrigation
- ▸Low-pressure gas mains
- ▸Industrial water
PN12.512.5 bar
- ▸High-pressure potable water
- ▸Industrial pipelines
- ▸Medium-pressure gas mains
- ▸High-rise water supply
PN1616 bar
- ▸High-pressure water supply
- ▸High-pressure gas mains
- ▸Mining industry
- ▸High-pressure industrial systems
PN2020 bar
- ▸Very high-pressure systems
- ▸Special industrial use
- ▸Water supply in mountainous regions
- ▸Critical infrastructure
PN2525 bar
- ▸Highest-pressure systems
- ▸Special-purpose projects
- ▸Extreme conditions
- ▸High-risk industrial use
Key factors when choosing PN
- ▸Maximum working pressure of the system
- ▸Temperature regime
- ▸Pipe diameter
- ▸Application
- ▸Environmental conditions
- ▸Service life
Safety factor
- ▸Potable water: 1.25
- ▸Gas: 2.0
- ▸Industrial use: 1.6–2.5
Recommendations
Potable water systems
- • Low-rise buildings: PN10
- • Mid-rise buildings: PN12.5–PN16
- • High-rise buildings: PN16–PN20
Gas systems
- • Low pressure: PN10
- • Medium pressure: PN16
- • High pressure: PN20–PN25
Industrial use
- • Standard: PN16
- • Heavy load: PN20
- • Special: PN25
Installation of polyethylene gas and water pipes
Polyethylene pipe installation is fast and straightforward. Thanks to the material's flexibility, pipes can be laid in both underground and above-ground systems with minimal complications.
- Flexibility: Polyethylene bends easily, allowing routing through complex terrain.
- Light weight: Lightweight pipes simplify transport and installation.
- Easy jointing: Dedicated fittings make connections fast and secure.
- Fewer fittings: PE systems need fewer fittings — lower cost and faster installation.
- Long service life: Correctly installed PE pipes deliver a long life cycle with minimal maintenance.
Applications
- ▸PE-to-metal transitions, flanged joints
- ▸Civil & industrial projects
