An economical and comparable
alternative to stainless steel piping.
The Alvenius lightweight steel piping system is thermo-plastic
coated inside and outside. This combines the strength of steel
and the resistance of thermo-plastic to wide variety of corrosive
The pipes are connected using Alvenius well known quick-couplings
or flanges making it possible to quickly exchange single pipe-lengths
and fittings. This also eliminates the need for expensive welding.
Alvenius piping systems are suitable for working pressures
up to 1000 psi/70 bar. See specifications.
The characteristics of thermo-plastic
Method of coating
- Extremely good adhesion - no risk of scaling or cracking.
- Elongation at break 800%.
- Good resistance to chemicals, especially acids and alkalies.
- Excellent weather resistant properties.
- Good corrosion protecting characteristics.
- Dielectric resistance.
- Safe working temperature continuous in air +150F/65C.
- Difficult to ignite building material.
The untreated steel surfaces are sand blasted to coatable
finish. The pipes are heated to the temperature for coating.
The pipes are coated using fluidised bed or electrostatic coating
methods. The thickness of film applied is 20-30 mil/500-700 microns.
Range of applications
Alvenius thermo-plastic coated pipe systems are found in
various types of industry, where primarily stainless steel has
been the traditional material for pipes that are subjected to
Mining and mineral processing
Municipal/waste water industry
Paper and cellulose industries
Food stuffs industry
The pipes can be used as process and cooling water pipes,
effluent and drainage pipes, high pressure pipes, fire fighting
pipes. Special dimensions and designs available
